2026 Comparison
Best Portfolio Monitoring Tools for Private Capital
Compare portfolio monitoring and fund management platforms for sponsors, operators, SPVs, and private capital teams — features, pricing, and which fits your operating model.
Portfolio monitoring is the backbone of modern private capital operations. Whether you are running deal-by-deal SPVs, a search acquisition, a holdco, or a committed fund, the tools you use to track company performance directly affect board cadence, lender communication, LP reporting, and value creation. The right platform eliminates hours of manual data collection, turns operating updates into decision-ready dashboards, and keeps investor relationships strong with professional, timely reporting.
We evaluated every major portfolio monitoring tool on the market across five dimensions: data collection methodology, metrics depth, LP reporting capabilities, valuation features, and total cost of ownership. Below, you will find detailed breakdowns of each platform, followed by guidance on which operating KPIs actually matter, how to structure your monitoring cadence, and how requirements differ between sponsor-led operating models and larger fund platforms.

Deep Dive: What Each Tool Actually Delivers
Archstone: The Sponsor Operating Command Center
Archstone is built for sponsor-led private capital teams that need a single platform for LP capital calls, portfolio company tracking, quarterly reporting, and investor communications. Pricing starts at $297/mo for the Core plan, which covers up to 15 portfolio companies and 25 LPs. The Growth plan expands capacity, adds custom branding on LP reports, and unlocks the full AI copilot (Archie) for due diligence summaries and automated narrative generation in quarterly letters. There is no per-company surcharge, which makes the economics significantly better than platforms that charge per portfolio company as your vehicle count scales.
Data collection is handled through a combination of company self-service portals and direct integrations. Portfolio companies receive automated monthly or quarterly metric requests via email, with a simple form that captures revenue, burn rate, cash on hand, headcount, and any custom KPIs you define. For companies that use QuickBooks, Xero, or Stripe, Archstone can pull revenue and cash data directly via API, reducing operator friction. The platform tracks essential metrics including ARR, net revenue retention (NRR), gross margin, burn rate, runway in months, headcount growth, customer acquisition cost, and lifetime value. Each metric is trended over time so you can spot inflection points or warning signs before they become crises.
LP reporting is where Archstone particularly shines for lean sponsor operations. The AI copilot generates first-draft quarterly letters that summarize portfolio-level performance, highlight top and bottom performers, and present fund-level metrics (TVPI, DPI, RVPI, net IRR) in a format institutional LPs expect. Reports export as branded PDFs or are delivered through the built-in LP portal with secure data room access. Valuation support includes the ability to log markups, markdowns, and write-offs with supporting notes, and the platform calculates implied portfolio value using your stated methodology (last round, comparable transactions, or revenue multiples). For funds that need to produce audited financials, Archstone exports clean data to your fund administrator or accountant.
Visible: Portfolio Company Data Collection
Visible has established itself as the gold standard for collecting metrics from portfolio companies at scale. Their pricing is structured in three tiers: Starter at $149/mo for up to 15 portfolio companies, Standard at $349/mo for up to 40 companies, and Enterprise at custom pricing for larger portfolios. Each tier includes unlimited users on the fund side, which is helpful for multi-partner firms. The per-company cost on the Standard plan works out to roughly $8.75/company/month, which is competitive but adds up quickly for large portfolios.
The core strength of Visible is its portfolio-company data collection workflow. Operating teams receive customizable metric request forms on whatever cadence you set (monthly or quarterly). The forms are clean, mobile-friendly, and quick to complete. Visible supports conditional logic in forms, so a SaaS company sees different questions than a hardware or services company. If a company misses its reporting window, the platform sends automated reminders and escalation emails. Response rates are strong because the experience is simple enough to complete quickly. Integrations pull data from Stripe, QuickBooks, Google Sheets, Plaid, and a dozen other sources, allowing some companies to report passively.
For metrics tracking, Visible covers MRR, ARR, burn, runway, headcount, NRR, churn, and custom metrics. The benchmarking feature compares portfolio companies against anonymized cohorts, so you can see whether a company's growth is strong or below median for its peer group. LP reporting is handled through a drag-and-drop update builder that lets you assemble quarterly letters from portfolio data, charts, and narrative blocks. Reports can be sent directly from the platform or exported as PDFs. However, Visible does not include fund administration, capital call management, or waterfall calculations. You will need a separate tool for those functions, which is why many funds pair Visible with Carta or a dedicated fund admin service.
Carta: Full-Service Fund Administration for Institutional Managers
Carta is the most comprehensive platform on this list, but it comes at institutional pricing. Fund administration services typically start at $3,000/month and scale based on AUM, number of portfolio companies, and complexity of your fund structure (multi-entity, sidecars, SPVs). For a $50M fund with 20 portfolio companies, expect to pay $4,000-6,000/month. Carta also offers a lighter-weight portfolio monitoring product (Carta Investor Services) for smaller funds, but pricing is still meaningfully higher than pure-play monitoring tools. The value proposition is clear: Carta replaces your fund administrator, your cap table tool, your 409A valuation provider, and your LP portal in one platform.
Data collection on Carta works differently from Visible or Archstone. Because Carta is the cap table provider for many private companies, it can already access certain financial data such as equity events, option exercises, and cap table changes without requiring a separate survey. For operational metrics like MRR and burn rate, Carta relies on manual entry by the sponsor team or direct data pulls from integrated accounting platforms. The platform tracks fund-level metrics (IRR, TVPI, DPI, MOIC by vintage) natively and can produce LP statements, K-1 schedules, and audited financial reports. Valuation is where Carta truly differentiates: its team of certified valuation analysts produces ASC 820-compliant fair value assessments, handles 409A valuations for portfolio companies, and provides defensible mark-to-market estimates for each position in your fund.
LP reporting through Carta is institutional-grade. The platform generates quarterly and annual LP reports, distributes capital call and distribution notices, tracks LP commitments and contributions in real time, and maintains a secure data room with granular access controls. For funds with institutional LPs (endowments, fund-of-funds, pension allocators), Carta's reporting format matches what these LPs expect and reduces back-and-forth during due diligence. The downside is cost and complexity: Carta is overkill for a first-time GP managing a $5M fund, and the onboarding process can take 4-8 weeks. For a deeper look at what institutional LPs expect in your reports, see our guide on LP reporting and investor expectations.
Kushim: Analytics-First Portfolio Intelligence
Kushim positions itself as the analytics layer for private capital portfolios, and it delivers on that promise. Pricing is custom and typically ranges from $500 to $2,000/month depending on the number of portfolio companies and funds under management. They offer a free tier for funds with fewer than five active portfolio companies, which makes it a reasonable starting point for lean operators who want more analytical depth than a spreadsheet can provide. The platform is designed for quantitatively-oriented fund managers who want to go beyond basic metric tracking into portfolio-level analytics, attribution analysis, and scenario modeling.
Data collection in Kushim is primarily manual or via CSV import, which is its biggest weakness compared to Visible or Archstone. Founders do not receive automated metric request emails. Instead, the GP (or an associate) enters portfolio company data into the platform after collecting it through whatever process the fund uses — email, phone calls, board meetings, or separate survey tools. Where Kushim shines is what it does with data once it is in the system. The platform calculates IRR, MOIC, TVPI, and DPI at the fund level, the investment level, and the sector/stage level. It benchmarks your fund's performance against vintage-year cohorts from Cambridge Associates and PitchBook data, so you know exactly how your Fund II is performing relative to peers. Cash flow modeling lets you project future distributions and unfunded commitments based on different exit scenarios.
Valuation methodology on Kushim is flexible: you can mark positions using last-round pricing, comparable company multiples, discounted cash flow, or a blended approach. The platform records your methodology for each position and generates an audit trail that your fund auditor can review. LP reporting dashboards are clean and data-rich, with the ability to export reports as PDFs or share interactive dashboards via a secure link. Kushim is best suited as a complement to another tool that handles data collection and LP communications. Many funds pair Kushim's analytics with Visible's data collection or use it alongside their fund administrator's reporting to add a layer of portfolio intelligence.
Affinity: Relationship Intelligence for Deal Flow and LP Management
Affinity is not a portfolio monitoring tool in the traditional sense. It is a relationship intelligence CRM used by deal teams that need automatic interaction capture. Pricing starts at $100/user/month on the Plus plan and scales to $150/user/month for the Premium plan, which includes advanced analytics, custom objects, and API access. For a three-partner firm with two associates, expect to pay $500-750/month. Affinity's value comes from its ability to automatically capture every email, calendar event, and interaction with management teams, LPs, co-investors, and deal sources — building a relationship graph that no one on your team has to manually maintain.
For portfolio monitoring specifically, Affinity is limited. It does not track MRR, burn rate, runway, or other operational KPIs. It does not send automated metric requests to company teams. What it does exceptionally well is track the relationship layer: when was the last portfolio check-in, who owns the next action, which co-investor relationship matters for the next deal, and which LP relationships need attention before the next capital formation push. The deal pipeline management is excellent, with customizable stages, automated data capture from emails, and integration with Crunchbase, PitchBook, and Clearbit for enrichment.
Most private capital teams that use Affinity pair it with a dedicated portfolio monitoring tool. Affinity manages relationships and deal flow; Archstone, Visible, or Kushim manages portfolio performance data. Affinity does integrate with many tools via API, so it is possible to pull portfolio company status into your Affinity records for context during interactions. If you are a lean sponsor deciding between a CRM and a portfolio monitoring tool and can only afford one, choose portfolio monitoring first — you can track relationships in a spreadsheet, but tracking 20+ portfolio companies in a spreadsheet breaks down fast.

What to Track in Your Portfolio (The Essential KPI Dashboard)
The biggest mistake sponsors make with portfolio monitoring is trying to track everything. You end up with 40 metrics per company, management teams hate filling out your forms, and you never actually look at most of the data. The best portfolio dashboards are ruthlessly focused on the metrics that drive your operating decisions and LP reporting. Here is what disciplined private capital teams actually track, organized by priority. For a comprehensive breakdown, see our guide to portfolio operations KPIs sponsors should track.
Tier 1: Track Monthly (Non-Negotiable)
Monthly Recurring Revenue (MRR) / Revenue. The single most important metric for most venture-backed companies. Track absolute MRR plus month-over-month growth rate. For non-SaaS companies, track the closest revenue equivalent (GMV for marketplaces, bookings for enterprise). MRR tells you whether the company is gaining traction or stalling, and the growth rate trend is often the leading indicator of whether a follow-on investment makes sense.
Burn Rate and Runway. How much cash is going out the door each month and how many months the company can survive at the current burn. This is the metric that determines urgency: a company with six months of runway needs your attention now, whether that means leading a bridge round or helping them cut costs. Track both gross burn (total spend) and net burn (spend minus revenue) to understand the full picture.
Cash on Hand. The raw number that, combined with burn, gives you runway. Founders sometimes overstate runway by using optimistic burn projections. Cash on hand is harder to fudge and gives you an independent data point to validate their runway claims.
Tier 2: Track Quarterly (Important for Follow-On Decisions)
Net Revenue Retention (NRR). The percentage of revenue retained from existing customers after accounting for churn, downgrades, and expansion. An NRR above 120% means the company grows even without acquiring new customers. Below 90% is a red flag that the product has retention problems. This metric is critical for SaaS companies and increasingly watched by growth-stage investors evaluating your portfolio companies for follow-on rounds.
Headcount and Hiring Velocity. Total employees and the rate of new hires. Headcount growth that outpaces revenue growth is a warning sign. Conversely, a company that is growing revenue 3x while keeping headcount flat is demonstrating operating leverage. Track headcount by department if possible (engineering, sales, G&A) to understand where the investment is going.
Gross Margin. Especially important for companies approaching Series A and beyond. Sub-50% gross margins in a software business signal that the product might be more services than software, which impacts how growth investors will value the company. Track the trend — improving margins quarter over quarter is a strong positive signal.
Tier 3: Track When Relevant (Situational Value)
Customer Acquisition Cost (CAC) and LTV/CAC Ratio. Important once a company has a repeatable sales motion. Irrelevant for pre-product-market-fit companies. A 3:1 LTV/CAC ratio is the common benchmark, but the payback period matters more: if CAC payback is 18+ months, the company needs significant capital to scale.
Pipeline and Bookings (Enterprise / B2B). For enterprise companies, track active pipeline value, win rate, and average contract value. These leading indicators predict revenue 2-3 quarters out and are often more useful than trailing revenue metrics for assessing the trajectory of the business.
Product Engagement Metrics. DAU/MAU ratio, retention curves, usage frequency. These matter most for consumer and PLG companies. Do not ask B2B enterprise companies for DAU/MAU when it is not relevant to the operating model.
How Top Sponsors Structure Their Monitoring Cadence
Collecting data is only half the equation. The other half is what you do with it and how often you review it. The best sponsors treat portfolio monitoring as a rhythm, not a fire drill before LP reporting deadlines. Here is the cadence that most disciplined private capital teams follow:
Monthly: Collect and Triage
Send automated metric requests to all portfolio companies in the first week of each month. Give operating teams a five-day window to respond. By the second week, you should have data from most of your portfolio. Spend one to two hours reviewing the data in your monitoring dashboard, flagging any company that shows a meaningful change: burn rate spiking, revenue declining, cash dropping below six months of runway, or covenant risk increasing. For flagged companies, schedule a call with the responsible operator that week. Do not wait for the next board meeting.
The monthly review is also when you should update your internal company status ratings. Many GPs use a simple green/yellow/red system: green means on track, yellow means needs attention, red means at risk. These ratings feed directly into your quarterly LP report and help you allocate your time. A portfolio of 25 companies means you cannot give equal attention to all of them. The monthly triage ensures you are spending your hours where they matter most.
Quarterly: Analyze and Report
The quarterly cycle is where portfolio monitoring translates into LP reporting and valuation updates. In the first two weeks of each quarter, review three months of portfolio data in aggregate. Calculate portfolio-level metrics: total portfolio revenue growth, median burn rate, number of companies that hit plan versus missed, follow-on funding activity. Update your fair value estimates for each position using whatever methodology your fund uses. Many lean private capital teams use last-round pricing with adjustments for material events.
Produce your quarterly LP letter by week three. The letter should include: fund performance summary (IRR, TVPI, DPI), portfolio company highlights (top performers, new investments, exits), portfolio company lowlights (markdowns, write-offs, companies at risk), and a brief market commentary. Tools like Archstone generate first drafts of these letters automatically from your portfolio data. For a detailed breakdown of LP reporting best practices, see our guide on what LPs expect from private capital reporting.
Annually: Full Portfolio Review and Valuation Audit
Once a year, conduct a comprehensive portfolio review. Evaluate every position: Is this company on a path to returning the fund? Should you be allocating more reserves for follow-on? Is it time to write down a position that has been stagnant? The annual review is also when most funds produce audited financials and update their ASC 820 valuations. If you use Carta's fund administration, they handle this process. If you self-administer, work with your auditor to produce defensible fair value estimates. This is also the right time to review your monitoring process itself: Are you collecting the right metrics? Is the cadence working? Are company teams responding on time? Iterate on your approach annually and you will build a monitoring machine that compounds in value over the life of your fund.
Portfolio Monitoring for Lean Sponsors vs Large Funds
The portfolio monitoring tools and processes you need differ dramatically depending on the size and structure of your vehicle. A lean sponsor managing several deal-by-deal vehicles has different requirements than a 10-person team managing $200M across three vintages. Here is how the approach differs:
Lean Sponsors and Smaller Vehicles
As a lean sponsor, you may own investor relations, board communication, lender coordination, and the back-office workflow at the same time. Your portfolio monitoring tool needs to be an all-in-one platform that minimizes the number of systems you manage. You cannot afford to stitch together five different tools and spend 10 hours a week moving data between them.
Recommended stack: A single platform like Archstone ($297-499/mo) that handles LP management, portfolio tracking, and reporting in one place. At this stage, you likely have a concentrated portfolio and a manageable LP base. You do not need enterprise analytics or custom benchmarking. You need a tool that lets you collect monthly data from company teams with minimal friction, produce professional quarterly LP reports in under an hour, and manage capital calls and distributions without hiring a large back office.
Common mistakes: Over-engineering your monitoring process with too many metrics, paying for fund administration services you do not need yet, and choosing tools designed for institutional funds that are 10x your size. The most important thing at this stage is consistency: a simple process you actually execute every month beats a sophisticated process you abandon after two quarters. For more on building an efficient operating stack, see our private capital operations guide.
Multi-Partner Funds ($25M-$500M+)
Larger funds face different challenges: multiple partners need access to the same data, institutional LPs demand specific reporting formats and compliance standards, and the sheer volume of portfolio companies (30-100+) makes manual data collection impossible. You also need to manage follow-on reserves, model portfolio construction, and produce valuations that withstand audit scrutiny.
Recommended stack: Visible ($349+/mo) for portfolio data collection plus Carta ($3K+/mo) for fund administration and LP reporting, or a combined platform if your fund admin offers monitoring capabilities. Add Kushim ($500+/mo) if your LPs expect vintage-year benchmarking or if your investment committee relies on quantitative portfolio analytics. Use Affinity ($500+/mo for a team) as your CRM for deal flow and LP relationship management.
Common mistakes: Relying on associates to manually collect data via email (it does not scale and data quality suffers), using a single tool that is strong in one area but weak in others (Carta is great for admin but not for data collection; Visible is great for collection but not for fund accounting), and underinvesting in the reporting layer that your institutional LPs see. At this fund size, your LP reporting is a product — it needs to look professional, be delivered on time, and contain the exact metrics your LPs track.
Frequently Asked Questions
What portfolio monitoring tool is best for a lean sponsor?
Archstone is built for sponsor-led operators: it combines LP management, deal pipeline, fund accounting, and AI-powered reporting in one platform starting at $297/mo. Visible is also strong if your primary need is collecting metrics from portfolio companies.
Do I need portfolio monitoring software for a small fund?
For funds with fewer than 10 portfolio companies, a spreadsheet can work initially. But once you have LPs expecting quarterly reports and multiple companies to track, dedicated software saves significant time and presents a more professional image.
How much should I budget for fund management software?
Budget $100-500/mo for a lean private capital operation. Larger funds with institutional LPs may need $1K-5K/mo for full-service platforms like Carta. The cost is typically covered by management fees and is well worth the time savings.
How often should you collect portfolio data from founders?
Monthly is the gold standard for core metrics (MRR, burn, cash on hand). Quarterly works for less time-sensitive data like headcount, NRR, and qualitative updates. Avoid asking more frequently than monthly — founders are building companies, not filling out surveys. Automated collection via tools like Visible or Archstone dramatically improves response rates by making the process painless. Set a consistent collection window (e.g., first week of each month) so founders build it into their routine.
What if founders do not report their metrics on time?
Non-reporting is the single biggest challenge in portfolio monitoring. Start with automated reminders — most tools send two to three follow-ups automatically. If a founder consistently misses reports, escalate personally: a direct email or text message works better than automated pings. Make reporting easier by reducing the number of metrics you request (five core metrics maximum) and integrating with tools founders already use (Stripe, QuickBooks). For chronic non-reporters, tie reporting to follow-on eligibility — not punitively, but as a fund policy that reserves are allocated to companies where you have visibility into performance. Most founders comply once they understand the connection between transparency and continued support.
Can you track public market comps alongside your private portfolio?
Yes, and you should. Tracking public company multiples in your sector gives you a real-time read on how the exit environment is shifting. If public SaaS multiples compress from 15x to 8x revenue, that directly impacts your portfolio valuations and exit timelines. Tools like Kushim allow you to set up public comp sets and track them alongside your portfolio. Carta includes comparable company analysis in their valuation services. At a minimum, maintain a simple spreadsheet of five to ten public comps in each sector you invest in, tracking EV/Revenue, EV/EBITDA, and revenue growth rates. Update it quarterly when you do your portfolio review.
What about using Airtable, Notion, or Google Sheets instead of a dedicated tool?
Spreadsheets and general-purpose databases work for very early-stage funds (under 10 portfolio companies, under 10 LPs). The breaking point comes when you need automated data collection from founders (building this in Airtable means maintaining custom forms and automation), LP-facing reports that look professional (exporting from Notion to PDF is painful), fund-level performance calculations (IRR and TVPI in a spreadsheet are fragile and error-prone), and auditability (your fund auditor needs clear data trails). If you are pre-first-close and building your track record with angel investments, Notion or Airtable is fine. Once you close your fund and have LP obligations, invest in a real monitoring tool. The transition cost only increases the longer you wait.
How do you handle markups and markdowns in portfolio valuation?
Many lean private capital teams use a simple methodology: carry investments at the last-round price until a material event justifies a change. A markup happens when a portfolio company raises a new priced round at a higher valuation, and a markdown happens when a company raises a down round, experiences a material adverse event, or fails to hit milestones that justified the prior valuation. Document every valuation change with a brief rationale and the supporting data. For LP reporting, show both cost basis and fair value for each position. Your fund auditor will want to see your valuation policy and evidence that you applied it consistently. Tools like Archstone and Carta log valuation changes with timestamps and notes, creating the audit trail automatically.
What metrics should you include in quarterly LP reports?
At minimum, every quarterly LP report should include: fund-level performance (net IRR, TVPI, DPI, RVPI), capital deployment summary (called vs committed, invested vs reserved), portfolio company roster with status (active, marked up, marked down, exited, written off), top three to five company highlights with key metrics, and any new investments or exits during the quarter. Institutional LPs also expect a brief market commentary and your outlook for the portfolio. Avoid vanity metrics and keep the narrative honest — LPs respect transparency about challenges more than spin. The best LP reports are four to six pages, data-rich, and delivered within 45 days of quarter-end.
