Raise your round without the spreadsheet chaos.
A cap table, data room and SEIS/EIS platform for UK startups. Branch your cap table to test a round without touching the real one, zoom from the headline split down to a single vesting tranche, and tell the agent what to change.

One table, every level
Zoom out for the board. Zoom in for the detail.
Most cap tables give you one flat view that someone updates when they remember to. RoundRaise starts at the ownership split and lets you click into a share class, then a holder, then a single grant and its vesting schedule.
Risk gets flagged at every level: unvested founder equity, a departed co-founder with no leaver terms, a pool that won't last to Series A. The numbers are the same all the way down, because there's only one table.

Risk flag: Unallocated pool is 8.7%. Tight for a Series A hiring plan.
Branches
Branch your cap table like code.
Spin up a branch for the round you're considering, run it, and see the diff against your live table line by line: founder dilution, pool top-up, SAFE conversions, exit payout. Merge the branch into main once the round closes, or bin it. Your real cap table doesn't move until you say so.
Think of it as Cursor for fundraising.

FAQ
Questions founders ask us
Still working through the details? Here's what founders ask us most before they start.
Contact usSee all questions and how we compare →Tell the agent what to change on your cap table or data room (add someone to the option pool, issue shares, record a transfer, share the data room with an investor) and it's done. Open a branch to test a round, diff it against your live table and merge it when the round closes. Plus a pre-filled SEIS/EIS advance assurance draft and CS01/SH01 filings: one platform instead of five disconnected tools.
No. RoundRaise doesn't match founders with investors or make introductions. It's a cap table, data room and SEIS/EIS advance assurance platform, so when you've found your investors, your round is modelled on a branch, your advance assurance is in hand, and your data room is ready to share.
The spreadsheet-and-lawyer patchwork most founders start with, and it does what Carta or SeedLegals do, built from the ground up around live conversation with your data instead of static records and forms.
A bolted-on chatbot answers questions about static records. RoundRaise's agent acts on them. Tell it to add someone to the option pool or issue shares, attach the paperwork, and your cap table updates. Ask what happens if you raise £500k at a £5m post and it opens a branch, runs the round on your actual table and shows you the diff, rather than retrieving a stored answer. It works the same way on your data room: create share links, email an investor their link, move documents into folders.
Cap table branches and SAFEs work for companies anywhere; SEIS/EIS specifically is UK-only, since that's a UK tax scheme by definition.
Import your existing cap table directly (see How It Works above), with no manual re-entry needed. Vestd, SeedLegals and Carta exports all import, and Standard includes white-glove onboarding from your previous provider to check everything has come across.
Monthly plans run to the end of the current month. The annual plan is paid upfront and runs for 12 months. No cancellation penalty either way.
