Joseph Davidson — Cjay's father-in-law — spent 18 months in a Cyprus prison cell for a crime he didn't commit. Through those months and the year that followed, Cjay sat alongside the legal team, reading evidence and hunting for the contradiction. They found it. Joseph came home — but 18 months of his life were lost to the speed at which humans can read, remember, and connect the dots.

Cjay started building a private tool to do faster what he had been doing manually — search, summarise, find contradictions, surface case law. When Joseph was free, it became clear lawyers in private practice need the same thing. To take it from prototype to product, Cjay assembled a team — Yaron Hersh as CTO, the mastermind behind the security architecture (SOC 2, GDPR, every backend safeguard that keeps a lawyer's client data confidential), senior contracts lawyers (led by Emma) to write the prompts and guardrails, and legal researchers to make sure every reference to case law holds up.

The privacy obsession — never sending a single byte of client matter to a cloud — came from a case where every leaked detail mattered. JurisAi started with one case. It became a serious product because that case taught us what serious means.
