Ghent, 5 May 2026 — leadstreet today announces the integration of Koho Collective (HubSpot Gold Partner). With this move, the organisation responds to HubSpot's rapid transformation into an AI-driven customer platform. The combined team of 22 specialists, with offices in Ghent and Antwerp, further builds on the broad HubSpot expertise in the region.
A shared vision on the future of HubSpot
HubSpot projects have long gone beyond software alone. Organisations today expect an integrated approach in which marketing, sales, service and commerce come together in one platform. The rise of AI and data-driven processes is accelerating that evolution and increasing the complexity of these projects.

That demands partners who are both strategically and technically strong. With the integration of Koho Collective, leadstreet directly addresses that need.
Continuity for clients, strengthened expertise
For Koho Collective's clients, day-to-day collaboration remains unchanged: they keep their familiar points of contact. At the same time, they gain access to a broader team with additional technical and strategic expertise.
"We built Koho Collective on the belief that technology must always serve business strategy. We found that same vision at leadstreet. By joining forces, we can respond faster to the technological shifts we're seeing today," says June van der Weyden.
Founder June van der Weyden joins as partner and becomes part of leadstreet's management team, alongside Johan Vandecasteele, Johan Vantomme, Michel Antonise and Hilde Lamaire. Her full team makes the move with her.
"Strong HubSpot experts are hard to find. When you find a team that matches both on substance and culture, you act. The growing complexity of HubSpot projects demands exactly this kind of reinforcement," says Johan Vandecasteele, managing partner at leadstreet.
A strategic move in a growth journey
The integration is part of leadstreet's broader growth strategy, developed in partnership with strategic partner Meja. The company aims to further expand its role within the HubSpot ecosystem by investing in talent and innovative solutions. With this move, leadstreet deliberately positions itself in a consolidating market where scale, expertise and vision are increasingly decisive.
