We are Rockstart

We’re here to empower founders to drive positive change on a global scale.

Back in 2011

Our plans were big, our ambitions were even bigger. We wanted to create the ultimate startup machine. And together with hundreds of founders, mentors and investors, we did.

Fast forward to 2024

We’re empowering founders to drive positive change in a world that seriously needs more sustainability. Creating a better food system, transforming the energy business, developing promising technologies.

Meanwhile, it’s not only about the first thousand days anymore. It’s about the entire journey, many years into the future.

So yes, we grew up. We went from accelerating growth to seed investing. Has the eager accelerator become a classical seed investor?

Guess not. People still find it hard to pin us down. And actually, we like that.

Our world is in the middle of a transformation towards a sustainable and regenerative future. But on our own, we could never have a global impact. So we enable others to challenge the system.
