More about us

Thirty years of combined renewable knowledge

When three specialists in the international world of fuels feel the energy transition seriously needs to speed up faster to get greener and cleaner sooner, there is only one way to go. So, in 2020 Bram van Santen, Ralph Brands, and Fabian Leeman made the jump and the energizing Connex B.V. was born.

Their knowledge of sustainable fuels was already solid. A large network already in place. And their entrepreneurial spirit ambitiously set to work. From day one, Connex does things differently to truly make an impact on 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.”
