About Simple Cap

Simple Cap started with a spreadsheet that kept breaking.

I was in the middle of raising a Series A. Every conversation with a potential investor meant updating a cap table model — adjusting the pre-money, adding a new investor line, tweaking the ESOP pool, then checking how it all flowed through to dilution. I'd copy a tab, rename it, change a few numbers, and inevitably break a formula three columns over.

I looked for a tool that could do this simply. Something where I could plug in a valuation, add investors, set an option pool, and just see what happens to ownership. No 45-minute onboarding. No annual contract. No sales call.

Everything I found was either built for lawyers managing post-close cap tables or priced like enterprise software. I didn't need a legal record of share certificates — I needed to sit down with my co-founder and say, “if we raise at this valuation with this ESOP, here's where we end up.”

So I built the tool I wished I'd had.

Simple Cap lets you model ownership across multiple funding rounds in minutes. Add founders, set up a seed round, stack a bridge note, plan your Series A — and watch dilution update in real time. No spreadsheet gymnastics. No surprises when you finally look at the numbers.

It's free for a single project, and a few pounds a month if you need more. That's it. No per-seat pricing, no annual lock-in, no hidden fees.

If you're planning a raise and want to understand what it actually means for ownership, I hope Simple Cap saves you the hours it would have saved me.
