Ownership is the most consequential math in a startup, yet most early cap tables live as a scary, error-prone spreadsheet nobody trusts. Come a raise or an option grant, a wrong percentage or a missed dilution can cost real money and real trust. You need a clear source of truth before, not after, the round.
The exact thing you needed, made for you.
Iris builds a clean cap table spreadsheet: founders and their equity splits, an option pool, and investors by round, with share counts and ownership percentages that recalculate automatically. It models pre- and post-money ownership and shows dilution across a new round, so you can see exactly who owns what — and what a raise does to it.
- Founders, option pool and investors by round

Model a round
Ask "what if we raise $2M at $10M pre?" and Iris shows the post-round table.
One prompt. A real deliverable. Not a template you fight with.
Most “free tools” hand you a rigid template and leave the hard part to you. Iris is a full autonomous agent: it does the thinking, writing, and designing, then opens the result in a live workspace where you refine it in plain English. Live models and trackers with real formulas you can keep editing.
Actually made for you
Original, specific output built from your details — never generic fill-in-the-blanks.
Editable in plain English
Don’t like a part? Just say so. Iris rewrites, restyles, and restructures on request.
Yours to export
Take it with you — export, publish, or drop it into the tools you already use.
Frequently asked
Does it calculate dilution automatically?
Yes. Ownership percentages and post-round dilution are live formulas — change the round and the table updates.
Can it model a new funding round?
Yes. Give Iris a raise amount and valuation and it produces the post-money cap table and each holder’s new percentage.
Is an option pool included?
Yes — set the pool size and Iris factors it into fully-diluted ownership.
Can I export it?
Export to XLSX to keep working in Excel or Google Sheets.
