About AfterQuery

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.

Overview

As Head of Growth, you will own one of the company's most important strategic assets: the supply side of our marketplace. The systems you build will directly determine our ability to serve customers, launch new products, enter new domains, and maintain our quality advantage.

This role sits at the intersection of growth, product, engineering, recruiting, and operations. Early on, you'll develop the playbooks yourself. Over time, you'll partner closely with engineering to transform those playbooks into software, automation, and scalable systems, all towards the end of creating a repeatable engine that can identify, recruit, and retain exceptional talent globally.
