What My Time At Tinder Revealed About Legal AI

Ruben Miessen spent years leading the product teams at Tinder and Match Group, where sitting through weekly legal committee meetings helped him develop a deep understanding of the processes that caused bottlenecks and frustrations.

Rather than build another generalist legal AI tool, Ruben co-founded LegalFly in 2023 with a laser focus on in-house legal and procurement teams at enterprises in highly regulated industries.

The Belgian startup now employs over 50 people across Ghent, London, and Dubai, and closed 2025 with 600% year-over-year growth - with 80% of clients coming inbound rather than through outbound sales.

In this episode, I ask Ruben:

• Why he built exclusively for in-house teams instead of law firms - and why that choice shaped everything from product to go-to-market.

• The role European data privacy regulations played in LegalFly’s product architecture and competitive positioning.

• His predictions for legal AI consolidation in 2026 - and why he thinks data quality will matter more than ever.

• Plus, the roadmap for LegalFly’s Series B and US expansion plans.
