This is not presented as a direct pitching role. Founders should use Pioneer Square Labs's official submission or contact route and follow the firm's published fit: Show the founder insight, Pacific Northwest connection, problem, earliest validation and whether the best fit is studio co-creation or a PSL Ventures investment.
