Quill was founded in 2024 by Rachel Singh and Tom Ostrowski — a former litigation associate at a top-five law firm and a former Clio engineer who had spent years building legal software from the inside of an industry they were only partially adjacent to. That mismatch showed up clearly over time: tools were being optimized for administrative efficiency, while the actual work of lawyering lived somewhere else entirely.

Their core observation was blunt: most legal SaaS has been designed by people who don’t practice law. As a result, the category has become good at managing surfaces — billing, time tracking, document storage — but largely blind to the underlying structure of legal thinking. Attorneys don’t operate in rows, pipelines, or CRM objects. They work in matters, arguments, precedent chains, and evolving narratives that don’t map neatly onto traditional software abstractions.

That gap has left small and mid-sized firms in an awkward middle ground. They’re too complex for lightweight solo-practice tools, but too lean to justify heavyweight enterprise systems built for large institutional firms. The result is fragmented tooling, duplicated effort, and a constant cognitive tax on legal teams trying to stay organized across disconnected systems.

Quill is built around a different abstraction entirely: organizing legal work the way lawyers actually think about it. Instead of forcing matters into rigid software structures, the product centers on reasoning flows — how arguments are constructed, how facts evolve across a case, and how documents, notes, and precedents connect over time. The goal isn’t just automation, but alignment with the mental model of litigation itself.

Under the hood, Quill acts less like a document system and more like a structured workspace for legal reasoning, where information is continuously linked across matters, timelines, and arguments. The emphasis is on reducing context-switching and surfacing relevant connections that would otherwise remain buried in scattered files and emails.

We led the seed in Q4 2025. Since then, Quill has expanded into over 60 firms ranging from 5 to 50 attorneys. The product is seeing strong retention, with renewal rates above 95%, and users reporting an average of six hours saved per attorney per week — driven not just by automation, but by the reduction of cognitive overhead in how legal work is structured and retrieved.
