From late nights in spreadsheets to a two-second verdict.
Start-Check exists because our founding team spent years doing this work by hand, and hand-built tools don't scale past your first hundred cases.
In 2020, our founding team was running manual wallet reviews for an OTC desk — pulling explorer data, checking sanctions lists one address at a time, and writing up findings in a shared doc that nobody outside the team could read. It worked, barely, until volume tripled in a single quarter.
We built the first version of Start-Check to solve our own problem: a single screen that traced a wallet, scored it, and explained the score in language a non-analyst could act on. Colleagues at other desks asked to use it. Within a year, screening wallets for other teams had quietly become the actual business.
Today the product looks different — more chains, faster tracing, audit-ready exports — but the goal hasn't changed: turn a messy on-chain trail into a clear, defensible answer, fast enough to use in the moment a transaction is actually happening.
