Marketing Lead

San Francisco, CA — On-site — Full-time

About The Company

We're an applied research lab curating data solutions for foundation-model development, serving the frontier of AI with a mission to deliver the best data to power the best models. Our work sits directly in the loop of how those systems improve. We've raised a Series A and grown to a $100M+ revenue run rate, backed by top-tier venture firms and angels from leading AI labs. Founded 2025, 11–50 people. Industry: AI research / data for foundation models.

About The Role

We're hiring our first marketing leader to build the marketing function from scratch and establish a clear brand across two audiences: a tier-zero destination for top researchers, engineers, and ops talent; and a highest-data-quality, research-led perception among the labs and customers we serve, generating inbound from teams that currently require bottoms-up outreach. This is an IC seat for the foreseeable future, with a team build expected within months if the foundation is strong.
