Insights & ideas

John Sarihan argues that legal services should be measured by deal velocity rather than billable hours, positioning speed of contract negotiation as the core value a law firm should deliver [1][2]. Alongside co-founder Ryan Daniels, he is reimagining how legal work gets done by building Crosby as an AI-powered firm dedicated entirely to contract negotiations [1]. Rather than building legal software for lawyers to use, Sarihan has structured Crosby as an actual law firm staffed with lawyers, reflecting a view that AI should be embedded directly into legal practice rather than sold as a tool alongside it [1]. This framing, captured in the title of his conversation on Training Data, signals a broader critique of the traditional billable-hour model as misaligned with what clients actually want from contract negotiation work [2].
