Ex-Tinder AI Wizards Fuel LegalFly’s €15M US Conquest
By Ben Thomson for LawFuel | November 24, 2025
Ghent, Belgium – Remember swiping right on Tinder? Now imagine swiping through contracts at warp speed. That’s the magic LegalFly is bringing to the staid world of law, courtesy of a founding team that once powered the world’s hottest dating app with AI smarts.
Fresh off a blockbuster €15 million Series A, this Belgian legal tech disruptor is gunning for America’s biggest law firms, and it’s not messing around.
AI Tinderr Pros Ditch Dates for Documents
LegalFly isn’t your average startup. Founded in 2023 by four AI heavyweights from Tinder – CEO Ruben Miessen, CTO Kasper Verbeeck, CDO Gregory Vekemans, and COO Dennis Montégnies the company was born from frustration.
“We watched our own legal teams at Tinder drown in paperwork, slowing down everything,” Miessen told LawFuel.
Their fix was to build a hyper-secure AI copilot that slashes grunt work by 60%, letting lawyers focus on the big-picture wins.
These aren’t rookies. At Tinder (and parent Match Group), they scaled AI to match billions of users. Now, they’re matchmaking lawyers with efficiency.
“Our product-first mindset from Tinder drives us,” Miessen says. “We build what users crave – no fluff.”
What LegalFly Does
In a world where generative AI promises the moon but delivers data nightmares, LegalFly stands out. Their platform is an “agentic AI workspace” for in-house legal, compliance, and procurement teams. Think:
- Instant Contract Review & Risk Analysis: Spot red flags in seconds, not hours.
- AI-Powered Drafting: Generate airtight docs with legally-trained agents.
- End-to-End Automation: From litigation prep to compliance checks, all with bank-level security.
The key hook forr LegalFly is it’s LLM-agnostic (works with any AI model) and anonymizes every document for on-premise fortress-like protection.
Firms like Slaughter and May and Allianz are already hooked LegalFly’s beta has a 100+ client waitlist across Europe.
“Generative AI is the biggest shift of our lifetime,” Miessen declares. “We empower pros to deliver more value – safely.” Customers rave: 60% faster reviews, zero security slips.
€15M Series A Eyes Star-Spangled Expansion
LegalFly’s war chest just exploded. The €15M Series A, led by Notion Capital with redalpine and Fortino Capital, caps a blistering rise from their €2M seed (also redalpine-led, with Google DeepMind’s Mehdi Ghissassi on board). Total haul: €17M+ in under two years.
The cash is turbocharging a US invasion. “We’re tripling our team to 100 by year’s end and storming American markets,” Miessen reveals. Expect beefed-up features, deeper partnerships, and a foothold in finance and insurance – sectors LegalFly already dominates in Europe.
Investors are swooning. “LegalFly’s vision and execution are unmatched,” says Notion’s team. Redalpine’s Sebastian Becker adds: “Their security focus is a game-changer – we’re witnessing legal AI’s future.”
The Legal AI Gold Rush Hits Main Street
Legal tech is booming, but trust issues linger. With breaches costing firms millions, LegalFly’s “secure-by-design” ethos is catnip. As US expansion ramps, expect headlines: Tinder alums vs. Big Law bureaucracy.
“We’re not replacing lawyers – we’re unleashing them,” says Miessen.
