What is a cap table?

Answer

A capitalisation table records who owns what proportion of a company — every shareholder, every class of share, every option and everything that could become a share.

What it contains:

Every shareholder and the number and class of shares held.

Share classes and their rights — ordinary, preference, founder shares, non-voting — which matter enormously, because ownership percentage says nothing about rights.

Options and warrants, granted and reserved.

Convertible instruments not yet converted.

Percentages on both an issued and a fully diluted basis.

Why fully diluted is the number that counts. Issued share percentage flatters founders by excluding the option pool and anything convertible. Investors negotiate on fully diluted figures, and a founder reasoning from the issued figure will consistently overestimate their position.

Why it must be accurate from the start. A messy cap table is one of the most common reasons a funding round or acquisition stalls, and the problems are almost always historical:

Shares promised in conversation and never documented.

A founder who left still holding a large stake, with no vesting to claw it back — the single most damaging cap table defect, and one that can make a company uninvestable.

Too many small shareholders from early informal investment, making every subsequent decision requiring shareholder consent slow.

Missing paperwork — share certificates, board minutes, option grant documents — which surfaces in due diligence and delays everything while it is reconstructed.

Options granted without a scheme, or with unclear terms.

What good practice looks like: keep it in one authoritative place rather than several spreadsheets; reconcile to the statutory register of members and Companies House filings, since the legal record is what counts; document every issue and transfer at the time; use vesting with a cliff for founders as well as employees; and model prospective rounds before agreeing terms.

Dedicated cap table software exists and is worth it beyond a handful of shareholders, largely because it enforces consistency.
