Equity & Growth: Competitive salary and meaningful equity. As we scale, you’ll have the opportunity to shape the engineering organization and lead major technical initiatives.

Overview

We're looking for a Head of Enterprise GTM to own and build AfterQuery's enterprise go-to-market function from the ground up. This person will be responsible for driving enterprise customer acquisition, developing strategic commercial partnerships, structuring complex deals, and ensuring successful delivery of the engagements we sell.

This is a senior, highly autonomous leadership role for someone who can operate as both a strategic leader and a hands-on individual contributor. You will personally identify and pursue high-value enterprise opportunities, build relationships with senior decision-makers, lead complex sales cycles, and translate customer needs into commercially sound engagements that our research and technical teams can execute.

Our core research and technical capabilities are already in place. The primary challenge is bringing those capabilities to the right customers, creating compelling commercial opportunities, and converting them into successful, long-term partnerships. You'll work closely with our researchers and technical leadership to understand what we can deliver, while taking full ownership of how we position, sell, structure, and bring those solutions to market.

You'll own the entire customer lifecycle, from initial prospecting and relationship development through commercial negotiation, engagement launch, delivery, and account expansion. This includes building the operating processes and commercial infrastructure needed to scale the function, as well as establishing and leading a high-performing GTM team as the business grows.

We're looking for someone who can independently drive results from day one, create structure where little exists, and build a repeatable enterprise GTM engine without relying on an existing sales organization or extensive support.

What You'll Do

Own and Build the Enterprise GTM Function

Take full ownership of AfterQuery's enterprise go-to-market strategy, commercial execution, and overall customer acquisition efforts.

Define and execute the strategy for identifying, pursuing, and closing high-value enterprise opportunities across AI, technology, and other relevant industries.

Personally drive outbound prospecting, relationship development, pipeline generation, and strategic account acquisition while building the foundation for a scalable sales organization.

Establish our enterprise sales motion, including target account strategy, qualification, positioning, pricing, deal structures, and commercial negotiations.

Identify the highest-value customer use cases for custom evaluations, data generation, model training, and post-training engagements.
