Keep is onchain fundraising built for solo builders, indie hackers, and small teams. Raise directly from your backers; your token is tradable the moment the raise settles — no liquidity to seed, the contract locks it for you. If the launch doesn't work out, the contract automatically refunds most of the money to backers. Non-custodial, live on Solana mainnet.

Hey PH — we're a small team. Keep exists because I kept watching indie AI builders with real users and no realistic way to raise. Keep is what I wished existed for them. The idea is simple: backers fund the builder in USDC; if it doesn't work out, the contract refunds them automatically. Making that un-gameable was the actual work — price gates on a time-weighted average, founder vesting, permanently locked liquidity, and no admin keys anywhere in the money path. Every rule came from attacking my own design. The exact numbers are in the gallery above, and the full mechanism is at keep.coffee/how-it-works. One question for the builders here: right now every raise has a fixed target of 20,000 USDC. Is that the right size for a solo builder — too small to matter, or enough to ship on?

How does the refund mechanism actually work if the launch fails partway through, and do backers need to manually claim their refund or does the contract push it back automatically?

Tried it out yesterday and the auto-refund feature is genuinely reassuring for backers, something most fundraising tools skip over entirely.
