Activity in this selectionOct 19, 2026 · Sep 20, 2026

FJ Labs specialises in early-stage marketplaces and network-effect businesses, co-investing globally with a particular focus on the US.

It looks for capital-efficient businesses with sound unit economics and the potential to lead their markets. Its stated process typically reaches an investment decision after two hour-long calls over two weeks.

FJ Labs takes an angel-style role: it does not lead rounds or take board seats. It joins institutional venture investors and helps portfolio founders prepare subsequent financings through introductions to other funds and its marketplace network.
