More about us

Thirty years of combined renewable knowledge

When three specialists in the international world of fuels felt that the energy transition needed to speed up to get greener and cleaner sooner, there was only one solution: in 2020, Bram van Santen, Ralph Brands, and Fabian Leeman made the jump and Connex B.V. was born.

They had a vast knowledge of sustainable fuels. A large network in place. And an ambitious entrepreneurial spirit. From day one, Connex has done things differently to truly impact the path to achieving Net Zero.

Our Founders

Bram van Santen

Corporate Director
Bram is dedicated and his energy is inexhaustible. He doesn’t believe in limitations: “We just need to search, find or adept to a solution and push through the existing boundaries. I firmly believe in the green value of our product, and that with it we can really speed up the energy transition.”

Fabian Leeman

Operational Director
For the past twelve years, Fabian has dedicated his working life to a more sustainable future of fuel, seven of which he was active worldwide in renewable diesel. “At Connex, we have this very energetic and ambitious team, and it is a real joy to scale up together!”

Ralph Brands

Commercial Director
“As a child, I enjoyed walking in the forest, enjoying all the beauty nature offers. What bothered me was the rubbish people left behind, polluting it. How wonderful it is to be still focused on waste and residues, to find innovative solutions and high-quality applications to achieve beautiful things and change the future for the better.”
