Frequently asked questions
Who runs investment decisions at FJ Labs?
Investment decisions are led by co-founders and partners Fabrice Grinda and Jose Marin, who jointly oversee the firm's deal flow. A supporting team of venture partners, including experienced marketplace founders and operators, aids in sourcing and diligence. Final authority rests with the founding partnership.
How does FJ Labs source proprietary deal flow?
FJ Labs sources primarily through a high-volume inbound engine, attracting over 200 deals per week from founder referrals and its own marketplace network. The firm's stated approach is to screen this top of funnel rapidly and invest only in the top 2 to 3 percent it deems most promising. This volume model relies heavily on the firm's marketplace brand and the founders' personal reach.
Is FJ Labs structured as a traditional venture capital firm?
No. FJ Labs operates with the posture of an angel investor but deploys capital at a scale characteristic of institutional venture. It does not fit a typical multi-fund VC structure and instead makes fast, conviction-led decisions, with a particular capability in helping portfolio companies raise subsequent funding rounds.
What investment stages does FJ Labs typically target?
FJ Labs targets early-stage marketplace startups, spanning seed through start-up phases and extending into expansion and late-stage venture. Its sweet spot is getting into companies early, using its operational background to guide founders and then supporting them through the fundraising lifecycle.
Which sectors does FJ Labs explicitly focus on?
FJ Labs concentrates almost exclusively on marketplace businesses. The firm's investment thesis is built on a deep sector expertise in two-sided marketplaces, and it describes itself as marketplace experts, filtering its massive inbound deal flow through that specific operational lens.
Does FJ Labs participate in fund commitments or only direct deals?
Based on its described investment posture, FJ Labs engages in direct venture investments rather than fund-of-funds commitments. It writes checks directly into companies identified through its proprietary screening process, consistent with its high-velocity angel-style approach.
What is FJ Labs' geographic investment focus?
FJ Labs pursues a global investment strategy with a primary focus on the United States. It maintains physical offices in Canada, including Toronto, Montreal, and Kitchener, reflecting an active North American investment corridor alongside broader international marketplace bets.
