Greenlab

Greenlab is a Brussels-based accelerator dedicated to circular and urban industrial projects. We support entrepreneurs who have validated their pilot system and are ready to take a critical next step: structuring a strategic, controlled, and scalable go-to-market approach.

Our mission is clear: transform innovation into predictable, revenue-generating traction, and prepare your venture for robust industrial growth.

 

Why join Greenlab ?

Powered by hub.brussels and co-funded by the European Regional Development Fund (ERDF), Greenlab is the leading accelerator for securing the market entry of circular industrial projects.

Specifically designed for projects at the CRL5/TRL6 maturity level, our 4-month intensive program bridges the gap between a successful pilot and a robust industrial rollout. We focus on circular and urban industries – from sustainable construction to industrial tech – helping founders mitigate scaling risks, secure their commercial traction, and prepare for high-impact industrial operations in the Brussels-Capital Region.

The Greenlab program provided both knowledge and recognition, as well as rich, high-quality support—but above all, a sense of belonging to a community. Because a strong network is a real asset in entrepreneurship and in the growth of any project

Greenlab gave babyloop exactly what an early-stage startup needs: structure, challenge and momentum. The program helped sharpen our strategy, validate key assumptions and connect with an incredible community of mentors and entrepreneurs. It’s an environment that pushes founders to think ahead and move faster. Winning the public award was a fantastic encouragement from the community

Greenlab helped us take a step back and explore different customer segments in a concrete way. Through the market research and financial projections carried out during the program, we were able to validate certain assumptions and refine our strategy. This notably led us to focus on the B2B sector in order to reach profitability

Bel Albatros was founded seven years ago, and Greenlab was the very first support program we joined. It helped us structure our approach and develop our first product made from recycled plastic. Today, we create a durable, custom-made material designed as an alternative to marble, used by architects and designers for interior design projects. Greenlab played a key role in transforming an idea born in a FabLab into the innovative entrepreneurial project we carry forward today

Taking part in the Greenlab program in 2020 was a turning point in the launch of our company. The program helped us structure our offer in a clear and coherent way by confronting it with market requirements and expert feedback. But beyond the methodological support, it was the supportive ecosystem we discovered that truly made the difference. Being surrounded by committed entrepreneurs, available coaches, and an active network gave us the momentum—and confidence—we needed to move from idea to action. Greenlab is much more than an accelerator: it is a community that provides the right tools at the right time
