Pioneer Square Labs

Pioneer Square Labs is a Seattle-based startup studio and venture capital fund that builds and invests in the next generation of technology-driven companies.

Founded in 2015 by Greg Gottesman and a team of veteran operators, Pioneer Square Labs (PSL) functions as both a venture studio and a dedicated investment fund. The studio side ideates and validates hundreds of concepts annually, spinning out high-growth startups like Boundless and Recurrent through a rigorous process of rapid prototyping and customer discovery. Its venture arm, PSL Ventures, manages over $180 million in assets to back early-stage founders across the Pacific Northwest. By integrating engineering, design, and recruiting resources directly into the formation phase, PSL significantly compresses the time required to move from initial hypothesis to a funded, scalable business.
