- We are a tight-knit team of 17, working 4 days in-person in downtown San Francisco.
- Our backgrounds sit at the intersection of finance and engineering.
- As a group, we have built accounting systems at Affirm, ledgers at Stripe and Robinhood, and companies from the ground up.
- We have passed CPA exams, built finance teams from one to dozens, shipped 0→1 products, and scaled systems that support billions in transactions.
- We understand our customers because we have been in their shoes.
- We care deeply about correctness, trust, and building systems that last.
- We are opinionated about the future of finance and committed to building it together.
- We are defining the Operational Ledger, a new financial foundation for how businesses truly understand themselves.
- If you want to work on deep, consequential systems, financial data is one of the hardest places to do it well.
- Finance sits at the center of every business, yet most software makes it difficult to see how numbers are constructed or why they can be trusted.
- Accounting is the foundation.
- The goal is a live, queryable financial system businesses can reason from.
- By running the day-to-day accounting workflows alongside our customers, we turn messy, judgment-heavy financial data into a reliable, queryable system of record.
- Our backend systems establish correctness.
- The frontend must establish proof.
- In accounting, trust comes from traceability.
- When someone sees a number in Quanta, they should be able to drill into it, follow it to the underlying transactions, and understand how it was produced.
- If they cannot do that, the system does not matter.
- As we scale engineering output, including agentic tools that generate code, frontend coherence becomes a systems problem.
- The interface has to remain consistent, explainable, and structurally aligned with the ledger beneath it.
- We are hiring a Staff Frontend Engineer to define how that system is built.
