Real execution, not just signatures

Live round progress
Total raised against your target, and who has signed and who has paid, at a glance.
Investors complete accreditation and identity checks before the money moves. How accreditation works
Legally binding agreements made easy.
Every investment generates a complete, ready-to-sign agreement, filled in with your round's terms and the investor's details. No separate e-signature or document tool needed.
Bespoke agreements
Tailored to each investor and their terms, downloadable as a PDF by either side, and kept with the investment record.
Cryptographic signatures
Both sides sign with their wallet. Every signature is timestamped, checked against the signer's wallet, and kept with the agreement.
