Investment Thesis

FJ Labs is a stage-agnostic venture capital firm focused on marketplace and network effect businesses at venture scale. Founded by Fabrice Grinda and Jose Marin, the firm believes in backing visionary founders who can execute on their vision with demonstrated passion, grit, and tenacity. The firm has amassed the world's largest portfolio of marketplace startups with over 30 unicorn exits, making it one of the most successful marketplace-focused VCs globally.

Sector Focus

FJ Labs specializes exclusively in marketplace and network effect businesses:

  • Multi-sided platforms: Business models that create value through network participation

Notable past investments include Alibaba (largest e-commerce platform), Coupang (e-commerce), Flexport (logistics), Delivery Hero (food delivery), Shipbob (fulfillment), Properly (real estate), Wallapop (classified marketplace), and Rappi (delivery in Latin America). These investments span geographies and demonstrate the firm's global marketplace expertise.
