About The Position

Crosby is an AI-first law firm reimagining corporate legal services from the ground up. They are a team of technologists and legal experts who build proprietary technology and human-in-the-loop workflows that meaningfully improve how lawyers and machines work together — delivering speed, consistency, and quality across high-stakes work. Their systems review complex documents faster and with exceptional accuracy, combining advanced AI with structured legal expertise. Clients receive AI-powered redlines, commentary, and negotiation guidance within hours, at a predictable, volume-based price. Backed by Sequoia, Index Ventures, and Bain Capital Ventures, they're building the end-to-end contracting platform for the next generation of fast-growing companies. The Controller role is the first to build and own Crosby’s accounting and financial operations function from the ground up.

The Controller will partner closely with the leadership team and investors to deliver accurate, timely financials while building processes and systems that support rapid growth. The ideal candidate is deeply technical and highly pragmatic, able to operate at startup speed while maintaining institutional-grade rigor.
