Best Cap Table Software for Startups (2026)

Most founders start looking for cap table software for startups the moment a spreadsheet formula breaks in front of an investor. By then the real question — which tool actually fits a company this size — has already been rushed.

This guide sorts the credible options in cap table software for startups into three honest tiers, by stage rather than by a flat 'best overall' ranking, so you can pick the one that matches where your company actually is today.

Why stage matters more than features

Cap table management means different things at different points in a company's life. At pre-seed, it means modelling — working out what a SAFE, a new hire's option grant, or a future round will do to everyone's ownership, before any of it is signed. At Series A and beyond, it means administration — issuing real grants, running 409A valuations, and giving investors and employees a portal they can log into and trust. Both are legitimate uses of the phrase 'cap table software,' which is exactly why comparison lists that treat the category as one flat market end up confusing more founders than they help.

Buying administration tooling before you need it adds cost and process to a company that just needs answers fast — most of that machinery sits unused until you've actually issued a real grant. Buying pure modelling tooling once you're issuing real equity at volume leaves you without the compliance trail a later diligence process will ask for, and rebuilding that history from memory is far harder than setting it up properly from day one. Matching the tool to the stage is the actual decision — not which logo looks most established, and not which one a friend's startup happens to use.

Cap table modelling vs cap table management: not the same job

The two phrases get used almost interchangeably, but they describe different work. Cap table modelling is exploratory: you're testing what-if scenarios — a new SAFE, a bigger option pool, a priced round at a different valuation — before anything is legally binding. Nothing you do in a modelling tool needs to be defensible to an auditor, because nothing has actually happened yet.

Cap table management is the opposite: it's the system of record for equity that has actually been issued. It needs to survive an investor's diligence request, back a 409A valuation, and hold up if a regulator or acquirer ever asks to see it, which is part of why guidance from bodies like the SEC treats accurate ownership records as a compliance matter, not a nice-to-have. Confusing the two jobs is how founders end up either overpaying for administration they don't need yet, or under-provisioning the record-keeping a funded company actually requires.

Tier 1: Free, self-serve modelling for pre-seed founders

If your company hasn't issued a priced round yet, this is almost certainly the tier you need. A free cap table tool is for running scenarios — what does a $500k SAFE at a $6m cap actually cost the founders in dilution, what happens if the option pool grows before the next raise, how much does a second founder's departure change everyone else's percentage — not for storing legally binding ownership records. Nothing here needs to survive an audit, so speed and clarity matter more than compliance features.

• Foundily — free calculators covering cap tables, SAFEs, dilution, option pools, and exit waterfalls, plus an API and an MCP server so agents and spreadsheets can pull the same maths programmatically. No 409A support and no issuance workflow — that's a deliberate scope, not a gap, and it's exactly why the core calculators stay free rather than gated behind a funded-stage price tier.
• Gust Equity Management — sits alongside Gust's incorporation and back-office tools, a sensible fit if you're already using Gust for company formation and want basic equity tracking in the same place rather than a separate account with a separate login.
• LTSE Equity — a free tier for cap table record-keeping from the Long-Term Stock Exchange, leaning slightly more towards ownership tracking than pure what-if modelling, but still accessible with no funded round required to get started.

Foundily fits here specifically, not further up the list, and we'd rather say that plainly than let a comparison post imply otherwise. It's free cap table software built for modelling decisions quickly — including through an API an agent or script can call directly, which is unusual at this end of the category — not for replacing a system of record once you're issuing real grants.

Tier 2: Systems of record for funded startups

Once you've closed a priced round and started issuing real option grants, modelling alone stops being enough. You need equity management software that can run a 409A valuation, issue grants with e-signature, and give investors and employees somewhere to check their own numbers without emailing the finance lead. This is the tier most people mean when they say 'cap table software' by default, and it's where switching costs start to matter, because real legal records now live inside the platform, not just numbers you're testing.

• Carta — the category's most established name, with broad coverage across 409A valuations, option issuance, and investor relations reporting. It's the default choice for many funded startups, though its scope and pricing structure lead some companies to look elsewhere as they scale — our Carta comparison and Carta alternatives roundup cover that in more depth if you want a direct like-for-like comparison.
• Pulley — built specifically around modern cap table workflows, with a strong reputation for scenario modelling and clean handling of SAFEs and convertible notes alongside issuance. A common landing spot for teams moving off spreadsheets or switching away from a heavier incumbent platform — see our Pulley alternative comparison for how it stacks up feature by feature.
• Ledgy — a European-headquartered equity management platform, popular with startups managing cap tables across multiple jurisdictions, with investor portals and compliance reporting built around that international use case from the outset rather than bolted on later.

Tier 3: Enterprise-scale equity administration

A smaller group of companies — larger private firms, pre-IPO businesses, and public companies — need equity administration at a different scale entirely: broad-based plans across thousands of employees, multi-country payroll and tax integration, and filings tied to public-market reporting obligations. Commentary hosted at Harvard Law's corporate governance forum reflects how much heavier the reporting expectations get once a company reaches this size.

• Shareworks (by Morgan Stanley) — an established equity plan administration platform aimed at larger and public companies, covering broad-based plan management, statutory filings, and integration with payroll and brokerage systems at a scale that early-stage tools simply aren't built to handle.

If your company is still counting its cap table holders in the dozens, this tier is almost certainly overbuilt for where you are. It becomes relevant later, once headcount and plan complexity grow well past what a founder can track by memory — not now.

What to actually check before you commit

There's no single best cap table software for every company — only the one matched to your stage. Beyond the marketing page, a handful of details tell you more about whether a given tool will actually fit than any feature list does. Ask these before you sign up, not after you've moved a quarter's worth of data in.

• Does it handle SAFEs and convertible notes as pending, not as issued shares, until they actually convert? Getting this wrong overstates dilution before it should count, and it's a surprisingly common bug in home-built spreadsheets as well as some cheaper tools.
• Does the fully diluted percentage include unallocated option pool shares? Leaving them out makes every other number on the table look bigger than it will really be, which is misleading to both founders and prospective hires reading an offer letter.
• Can you export your full data — holders, grants, vesting, and history — in a usable format? Investopedia and other reference sources treat cap table accuracy as basic financial hygiene, and that only holds up in practice if the data isn't locked behind a single vendor's interface.
• Does pricing scale with your stage, or does it jump straight to a funded-company price tier you don't need yet? A tool priced for a Series B team doesn't make sense for a two-founder company with no outside capital.
• If you need 409A support, does the platform provide it directly, or point you to a third party? Knowing which one before you sign up avoids an unpleasant surprise the first time a valuation is actually due.
• How is the API or export access documented, if you plan to pull cap table data into other tools or automate anything around it? Not every provider treats this as a first-class feature.

Switching providers without losing your history

Founders often delay picking cap table software because they worry about being locked into the wrong one. In practice, the underlying data — holder names, share classes, grant dates, vesting schedules — nearly always exports as a spreadsheet a new provider can import. Standard-form documents referenced by organisations like the NVCA use broadly consistent structures for this reason, which makes moving between tools less painful than founders expect, even after a couple of years of real activity on the old platform.

What doesn't move automatically is anything generated inside the old platform itself — signed grant documents, 409A reports, historical audit logs, and sometimes investor communication history. Download and archive those before you cancel anything, regardless of which tool you're switching to or from. It's a five-minute task while your account is still active, and a much longer one once it isn't.

Start free, upgrade when the stage actually demands it

The mistake worth avoiding isn't picking the wrong brand — it's picking the wrong tier for where your company actually is. Startup advice from sources like Y Combinator consistently treats early tooling decisions as reversible, and cap table software for startups is no exception: start with free modelling, move to a system of record once you're issuing real grants, and move to enterprise administration only if you get that big.

If you're pre-seed or pre-round right now, there's no reason to pay for anything yet. Run your scenarios in Foundily's free cap table calculator, and when it's time to add SAFEs, option pools, or a full round to the picture, check pricing for what comes next.
