The a16z Speedrun team is seeking a seasoned, high-impact Go-to-Market Partner to help our founders gain traction through modern Product-Led Growth strategies. This role will work hands-on with companies across both B2C and B2B, advising them on how to build repeatable, scalable growth engines, experiment with distribution channels, and validate product-market fit through user feedback and data-driven insights. While most of these startups are pre-revenue, the role will also support the effective implementation of founder-led sales as a complement to PLG, ensuring early learnings translate into both product improvements and initial revenue traction. This role requires an in-office presence 2-3 days a week in our San Francisco, CA office.
