Our product

useaccount.ai

We don't just build software for clients — we ship our own. useAccount.AI is the accounting inbox for small businesses: not accounting software you operate, but an inbox you feed — forward an invoice by email and it's booked automatically, saving up to 90% of accounting work.

It's proof of how we work: lean, product-driven, and built on modern cloud infrastructure.

How we work

Agile by conviction, not by ceremony — small senior team, short feedback loops, no hand-offs.

Discover

We align on outcomes and users — not on a 60-page spec.

Ship early

Working software in the first sprint, not a demo in month three.

Iterate

Real feedback reshapes the backlog every sprint. Priorities are allowed to change.

Evolve

Continuous delivery, measurable results, and a product that keeps improving after go-live.
