How we work
Built by engineers who care about correctness.
CircleSave is engineered test-first. Before we wrote the first React component, we had 69 automated tests covering the ledger engine, contribution service, and reconciliation engine. We do not ship financial logic without proof that it is correct.
We believe financial infrastructure should be boring in the right way: predictable, immutable, and reconciled. Our engineering culture prioritizes correctness over cleverness.
- ✓100% test coverage on all financial service code
- ✓Every PR reviewed against the double-entry invariant
- ✓Production incidents require a blameless post-mortem and ledger audit
- ✓No financial logic ships without an idempotency proof
Remote-first

Compliance-first
