What Cap Table Software Actually Does
At its core, cap table software does three things: it tracks ownership (who has how many shares of what class), calculates dilution (what happens to everyone's percentage when new shares are issued), and generates investor reports (ownership waterfalls, round summaries, board packs).
Enterprise platforms bolt on governance workflows: board consent, electronic signatures, option vesting schedules with automatic cliff triggers, 409A valuations, and investor portals. These are genuinely useful when you have 50+ stakeholders and active board management. At pre-seed, they are overkill.
The 80% use case for most founders is simpler: I have a spreadsheet, I need a professional PDF I can put in front of an investor. That is a solved problem that does not require a £100/month platform.
Features You Actually Need at Each Stage
| Stage | Required | Nice to Have | Skip |
|---|---|---|---|
| Pre-seed | Founder shares, simple ownership table, basic PDF export | Option pool placeholder | Waterfall analysis, 409A, investor portal |
| Seed | SAFE/convertible note modelling, investor share class, dilution table | Round summary with valuations | Full governance workflows, board consent tracking |
| Series A | Full waterfall analysis, anti-dilution clauses, option vesting schedules, board portal | Scenario modelling for future rounds | Nothing — you need the full stack |
The Problem With Complex Cap Table Software
The main platforms in this space were built in a different era of startup finance. Their pricing reflects that: £50–£200/month before you unlock the features you actually need. For a pre-seed company generating no revenue, that is a meaningful monthly cost.
Beyond price, there is a complexity problem. Most platforms assume you will migrate all your historical data, connect to your legal documents, and use their templates for future allotments. That is a significant time investment when you just need a clean PDF for a pitch meeting next week.
When your cap table has four shareholders and two share classes, you do not need a governance platform. You need a professional equity report that takes 60 seconds to produce.

When to Upgrade Your Cap Table Management
There are clear inflection points where a more comprehensive platform becomes necessary rather than optional:
You have 10+ shareholders with different share classes and option grants
You are preparing for a Series A with institutional investors who will run serious due diligence
You have active ESOP vesting schedules that need to be tracked automatically
You are doing a secondary transaction and need waterfall analysis to model liquidation preferences
Your board requires electronic consent workflows and a formal governance trail
Below those thresholds, you are paying for features you will never use. A verified equity report and a well-maintained spreadsheet will serve most seed-stage founders completely adequately.
Frequently Asked
Do I need cap table software before I raise a seed round?
You need a clean, accurate cap table — but not necessarily a subscription to cap table software. A verified PDF showing ownership, share classes, and fully diluted percentages is usually sufficient for seed investors. You can generate that from a spreadsheet or an AI tool without paying monthly fees.
What is the difference between issued shares and fully diluted shares?
Issued shares are what has actually been granted. Fully diluted shares include all options, warrants, and convertible notes as if they had all converted. Investors care about fully diluted percentages because that is what their ownership looks like after everything converts.
When should I switch from a spreadsheet to dedicated software?
When you have more than two share classes, an active option pool, or convertible notes outstanding. At that point, the dilution maths becomes error-prone in a spreadsheet and mistakes can create real legal problems in a due diligence process.
Can cap table software connect to Companies House?
Some enterprise platforms offer Companies House integration for UK companies, which can auto-populate allotments from filed confirmation statements. For most seed-stage founders, a manual CSV upload is faster and more accurate than relying on Companies House data, which can lag by months.
