GC AI is currently an AI platform for in-house lawyers to 10x themselves. Using the latest LLMs, we are building AI agents that can use company knowledge, leverage external sources, and connect with internal tools to provide better and faster legal advice to the rest of the company. Thousands of weekly active users tell us they “cannot imagine their lives without GC AI” - which has led us to 95% retention and a NPS of 75.
This is a once-in-a-generation opportunity to build for a $1T annual market. We have jaw-dropping product-market fit - growing our customer base from 0 to 500+ legal teams in a year and 3X ARR growth in the last 4 months. Join our Series A stage rocket ship backed by top investors like Sound Ventures, Fellows Fund, Guillermo Rauch and Worklife Ventures. GC AI is a small but mighty team of lawyers, engineers, sellers and doers. Here, you’ll have infinite room to grow and rethink how legal work gets done.
