Every innovation at Convex Energy starts with smart ideas which are a direct product of our traders’ experience and market knowledge.


We trade, develop & innovate

Convex Energy was founded in 2017 in Berlin. The basic premise: a unique dual setup where world-class traders and developers create value using an innovative tech stack.

Berlin is home to one of the most vibrant tech scenes, providing us with the entrepreneurial vibe and talent pool needed to build the most dynamic energy trading company on the planet. Thanks to our continued expansion across Europe, we have been able to diversify and enhance our tech and market excellence even further.

At Convex Energy, we have always understood that our number one success factor is people. It's part of our DNA to create an environment where transformative solutions can emerge. When our employees bring forward new ideas, we set up projects to develop and test them. If an idea shows promise, we make it happen.

We treat the ideas of our interns with the same respect as those from management. Our goal is to foster an inclusive work environment that encourages creativity, transparency, and fairness, where every employee is empowered to bring forward new ideas to elevate energy trading to the next level.
