For YC founders
Built for YC founders.
A YC batch runs on a clock. Holdfast runs on the same clock. We ship one production-ready feature in 14 days, fixed price, so you can spend founder time on the things only a founder can do.
Built for the pace you are already running
During a batch, every week is a demo, a metric, a conversation with users. You do not have a quarter to spend on a billing integration or an auth migration. A 14-day sprint fits inside the cadence you are already keeping.
We write a fixed scope and a fixed date on day 0, so you can plan around it. If we miss day 14, you get the full fee back. No surprise on a founder’s budget.
No contract that outlives your runway
We do not ask for a 12-month minimum or a retainer. One sprint is one sprint. That matters when your runway is measured in months and every commitment is a real decision.

Sprints worth reading.
