What Is tl;dv? The AI Meeting Tool Taking on Silicon Valley from Aachen


Every company runs on meetings. Sales calls, customer success check-ins, product reviews, leadership syncs. The problem isn’t the meetings. It’s that most of what gets said in them disappears the moment the call ends, buried in recordings nobody watches and notes nobody takes.

tl;dv fixes that. It records, transcribes, and summarizes meetings across Zoom, Google Meet, and Microsoft Teams, then goes further than any basic transcription tool by synthesizing intelligence across hundreds of calls at once. A sales leader can see patterns across their entire team’s customer conversations. A product manager can search six months of customer calls for every time someone mentioned a specific feature. Someone joining a new account can get up to speed on the full history of that relationship without sitting through hours of recordings.

This is what tl;dv calls organizational memory. Not a summary of what happened in Tuesday’s call. The accumulated intelligence of every conversation your company has ever had, made searchable and usable by anyone who needs it.

It competes directly with Otter.ai, Fireflies.ai, and Fathom, all US-based and US-funded, and differentiates on three things: multi-meeting intelligence rather than single-call summaries, European data compliance built in from the start, and a whole-company approach where every team has access, not just sales.

The Pivot That Built One of Europe’s Fastest-Growing AI Startups

Raphael Allstadt, Carlo Thissen, and Allan Betteral had been building Mosaeek since 2017, a video platform that let viewers record spontaneous reactions to content they were watching online. Its early users called it “the SoundCloud for video.” When a better opportunity came along, the team took it.

That opportunity was meetings. tl;dv launched in 2020, just as Covid hit and remote work became the only kind of work overnight. Other tools existed, but the emphasis had never been on the relentless pace of business: the back-to-back calls, the decisions made over video that used to happen in a room, the institutional knowledge that was now disappearing into recordings nobody had time to watch.

That was the gap. “Every major tech player has either built or invested in a product competing in this space,” Allstadt has said. “Meetings are one of the largest untapped sources of knowledge inside any company.” The team saw it early, built for it specifically, and grew faster than companies that had been in the space for years.

How tl;dv Built Eight-Figure ARR on €4.3 Million

When tl;dv decided to monetize in 2023, they didn’t hire a billing team or spend months building payment infrastructure. They implemented Stripe in three weeks and launched their subscription model without touching product development. “With Stripe we were able to generate eight-figure revenue from a standing start,” Allstadt has said.

The freemium model they built turned out to generate three to four times more leads than a free trial period would. That’s the kind of data point that only reveals itself if you’re watching the numbers closely enough to act on them. tl;dv watched, acted, and scaled.

600% year-on-year revenue growth followed. Then came the decision that changed the product category entirely: integrating Anthropic’s Claude. Before Claude, tl;dv summarized individual meetings. After Claude, it could synthesize intelligence across hundreds of them at once. As Allstadt put it, the platform evolved “from a meeting recap tool to a powerful intelligence engine.”

tl;dv is one of a small number of European startups that Anthropic has chosen to feature publicly as a Claude customer. For a company competing against well-funded US alternatives, being recognised as an Anthropic partner is a credibility signal that sits outside the usual metrics of funding rounds and headcount.

The numbers that followed the Claude integration tell their own story: 500% revenue increase, 300% growth in new customer sign-ups, 50% faster summary generation, and a 20-30% decrease in monthly customer churn.

By 2025, tl;dv had crossed eight figures in annual recurring revenue and is operating at 20-30% profit margins on a team of approximately 60 people. The average Sifted 250 company has raised €93.5 million to get to a comparable position.

tl;dv did it on €4.3 million, with no finance department, and a subscription model built in three weeks.
