About The Position

Arceus is building an AI-native law firm for fast-moving companies, helping them move contracts through legal with speed, transparency, predictable pricing, and quality. The Founding GTM Lead will design and run how Arceus grows, owning the go-to-market motion from first contact through signed customer and expansion. The role will build the narrative, systems, and execution that turn early demand into a repeatable revenue engine, while working directly with the founder and influencing company strategy. This is an in-person role based in San Francisco. The position involves building the GTM function from the ground up and defining go-to-market for an AI-native legal practice. The successful candidate will run experiments, develop repeatable systems across inbound, outbound, events, and content, and help establish Arceus as a category leader. The company expects urgent, consistent execution, ownership, and a positive attitude. The stated schedule expectation is 12 or more hours per day, six days per week, including weekends. Success milestones include starting GTM motions within the first week, generating pipeline and early results by day 14, identifying high-performing channels and closing initial deals by day 30, building repeatable systems by day 60, and owning a predictable engine producing qualified pipeline and closed revenue by day 90. Compensation is a base salary of $150,000–$190,000, meaningful equity, and the listed benefits.
