I have been in your shoes twice.
Daniel Kivatinos, CEO and co-founder of Loopfour, is a two-time YC founder. He built DrChrono through W11, then JustPaid through W23, now Loopfour. Across both companies he watched the same story repeat: finance workflows that should have been automated kept eating engineering time or lived inside a single person's head.
“Every YC company I have met hits the same wall: finance workflows that are too custom for off-the-shelf tools and too risky to leave in a spreadsheet. We built Loopfour to take that wall down. If you are in the batch, come talk to us. We will move fast.”

What you get
A managed finance automation team, not a platform to figure out.
Loopfour is not a no-code builder you staff yourself. Our engineers do the building and maintenance. You approve exceptions and see results.
Deterministic and auditable by default
Every run follows predefined steps. No surprise decisions at runtime. Full audit trail on every execution.
Typically live in two weeks
We scope your highest-pain finance workflow and get it running on your existing systems, fast.
Works even without an API
If a portal has no API, we connect through secure browser automation. Your stack works as-is.
Founder-friendly YC terms
Custom pricing built for early-stage companies. Talk to us and we will find something that works for your stage.
Start with one, scale when ready
We begin with your single highest-pain workflow, prove it out, then take on the next. No big-bang rollout.
