About us

The people behind SellZap.

We pair business judgment with engineering to make software that fits the way a team actually works. You work directly with Lorenzo and Diego, from the first conversation through delivery.

Built with the founders

You talk to the peoplewho scope and ship.

SellZap stays small on purpose: one commercial founder and one engineering founder on the work, not layers of account management.

Fairplay: reconciliation with a clearer review path.

We built Fairplay a bank reconciliation engine that matches bank movements with collections data, prepares the file for their ERP, and sets differences aside for human review. We validated it in parallel with their manual process before their team relied on it.
