Most term sheets ask for the pool to be created pre-money — that means existing shareholders (including you) absorb it. You can set it to 0 if no pool is being created this round.
This is the simple maths. Check the real numbers.

The things founders ask us
What is a cap table?
The record of who owns what in your company. It lists every shareholder, how many shares they hold, what class those shares are, and what percentage that represents — both as issued today and fully diluted once options and convertibles are counted.
Can I import a cap table I already have?
Yes. Start from your Companies House record, or upload the spreadsheet you already keep and we turn it into a structured record. You do not start from a blank page.
Is it really free?
Yes. Add as many shareholders and option holders as you need and export to Excel whenever you want, without paying and without a trial that expires. Paid plans add templates, e-signatures and included lawyer time.
Do you support ASAs, convertible loan notes and SAFEs?
Yes, fully. Track longstop dates, discounts, valuation caps and interest rates, so your fully diluted numbers stay right before anything converts.
Can I track option grants?
Yes. Create your pool and track every grant by name, with exercise price and vesting terms, rather than carrying the whole pool as one line.
What is the difference between issued and fully diluted share capital?
Issued share capital is the shares that exist today. Fully diluted also counts your option pool and anything your convertibles will turn into, and it is the number investors usually ask for. Both are in one view, one toggle.
What if I need an actual lawyer?
You can connect to one from inside SuLe, and they work from the same cap table rather than asking you to send a spreadsheet. Premium plans include 30 minutes of lawyer time every month.
How many shares should we issue at incorporation?
Any number works and the legal minimum is one, but a round figure like 100,000 keeps the maths readable: 1% is a clean 1,000 shares. The share count does not change what the company is worth.
How many shares should I issue when incorporating a UK startup?
How should co-founders split the equity?
Deliberately, after talking through contribution, capital and who is full-time. An equal split should be a decision rather than a default, and whatever you agree, the register of members is the legal record — not a spreadsheet or a handshake.
How big should our option pool be?
Around 10% of fully diluted shares is a common seed figure, growing to 10–15% by Series A. Size it against your next 18 to 24 months of hiring, role by role, rather than picking a round number.
Does the option pool come out before or after the investment?
It matters more than it sounds. A pre-money pool dilutes only the existing shareholders, so your effective valuation is lower than the headline figure. A post-money pool dilutes the new investor too.
