About us
Our Story
It started on a holiday in Portugal. Half relaxed, half obsessed, Onno couldn't stop thinking about the untapped potential in B2B marketing and sales. He saw teams working harder than ever, armed with more tools and data than ever before.
And yet.... tools didn't talk to each other. Teams operated in silos despite targeting the same buyers. Smart strategies launched at the wrong moment because detecting genuine buying signals remained impossible. It wasn't a people problem—it was an intelligence problem.
And the question became clear: What if AI could bridge this gap?
Not another tool, but the glue that connects what teams already have — making the whole process simpler, smarter, and finally effective for everyone.
Back home, Onno called Tim. He was fighting the exact same battle. When Jorn joined the conversation the idea sparked instantly. It sealed the deal. The three of them committed: let’s build this.
Eight months of relentless work followed. At times, the problem felt unsolvable. Then came the breakthrough. ZenGem was born — the AI-powered Co-Pilot for B2B Marketing & Sales teams: find and identify companies most likely to buy, understand what matters to them, and engage them automatically across the entire Buyer Journey. Allowing for a new way to grow your funnel.
