People often ask where the name Nebor comes from. In April 2025 Andrew moved into a new house in Haarlem, just outside Amsterdam. While he was unpacking, his next-door neighbor leaned over the fence with a glass of wine to welcome him. That neighbor was Yannick.
Andrew had his own lead generation agency for about two and a half years, building outbound systems in Clay for US-based B2B companies. Yannick had around ten years in enterprise SaaS sales and is one of the few salespeople who really values revenue operations. They came from very different worlds, but every time they talked about sales and marketing, they described the same problems and opportunities.
They decided to build something together because each is good at a different part of the same problem. Andrew thinks about the machine: the strategy, the automation and how the system is put together. Yannick thinks about the people who use it and whether it holds up in a real organization. They founded Nebor in January 2026, and the office is now in the same street.
We often get asked where the name Nebor comes from. In April, 2025, I've moved into our new house in Haarlem, just outside of Amsterdam. Whilst unpacking our boxes, my next door neighbor leans over the fence to welcome me with a glass of wine.
That person was Yannick. At the time, I've been running my own lead gen agency for about two and a half years, where I was building outbound systems for US-based B2B companies, mainly over the back of Clay.
I came from quite a different world than Yannick. My background is mainly within the startup world, working with companies that have massive total addressable markets. And Yannick, on his turn, has about 10 years of experience in enterprise SaaS sales. The good thing is that he is one of the few salespeople that understands the value and importance of revenue operations. So even though we came from different worlds, every time we spoke about sales and marketing, we kept describing the same problems and opportunities.
What actually made us decide to build something together wasn't that we agreed on everything. We were good at completely different parts of the same problem. So I think more about the machine, the strategy, the automation, and how the system is architected, whereas Yannick thinks more about how are people using it, how it actually holds up inside an organization.
So in January of 2026, we officially founded Nebor, your next-door co-partner. It started over the fence, and now we opened our office in the same street. So if you're wondering why we build things the way we do, we're building growth engines using AI, accessible for everyone, just like your next-door neighbor.
