FAQ
Questions founders ask us
Think of it as Cursor for fundraising.
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. Plus round modelling, 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 ownership is modelled, 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 recalculates your actual ownership in real time 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.
Round modelling 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. Standard includes white-glove onboarding to check everything has come across.
Your plan runs to the end of your current billing period. No lock-in, no cancellation penalty.
