AfterQuery is an applied research lab curating data solutions for foundation model development.
We serve every frontier AI lab with the mission of delivering the best data to power the best models. In doing so, we can make expertise that once took a lifetime to build available to anyone who needs it. Our customers are the ones building the foundation models themselves and our work sits directly in the loop of how those systems improve.
This is a rare opportunity to join a company at a defining moment in AI. Since raising our $30M Series A at a $300M valuation, AfterQuery has grown well over a $100M revenue run rate.
We're based in San Francisco and backed by leading investors including Altos Ventures, BoxGroup, and Y Combinator and angels from Google DeepMind, OpenAI, Anthropic, Meta Superintelligence Labs, and Microsoft AI.

This person will act as the main relationship owner for AfterQuery's most important frontier AI lab customers, focused on renewals, expansion, and lasting partnerships rather than one-off deals. They'll pursue new revenue within existing accounts, run senior-level touchpoints like quarterly reviews and contract negotiations, and feed customer input back into product and engineering decisions. As one of the company's first hires dedicated to this function, they'll also be building the account management and customer health processes from scratch while helping shape how AfterQuery approaches customer relationships going forward.
