Impact Capital's mission is to invest in inspiring, innovative and convincing impact businesses. Therefore, 3E was my first investment. 3E has now become a breeding place for spin-offs and for world leading digital solutions. For me, it was clear from the beginning when I invested in 3E that it has a special culture. The culture of being more human-centred, very internationally oriented, and a cross-road of many different cultures. It makes 3E an inspiring place to work, to be inspired by and to inspire other companies.


Piet Colruyt,
Impact Capital - CEO

After working for 10 years in the solar PV industry, I joined 3E in 2019 and got to continue with my passion for renewable energy. I moved from working on a few projects a year to seeing a new project almost every few weeks. I also have the chance to collaborate with big industry names, large solar PV plants and colleagues from all over the world. The work I do at 3E is very rewarding: when the client recognizes the quality of my work and wants to work with you again, it feels great! The company culture at 3E makes the return on investment even higher. It’s an easy, horizontal environment to work in and everyone’s door is always open. I have a lot of possibilities to develop my skills and appreciate the transparent and trusting way of working.


Thibault Desardurats,
Solar Consultant for the Technical Advisory team, Toulouse 

I actually started at 3E as a consultant, and I immediately felt welcome and part of the team because of the open mindset, honest communication and the trust they gave me from the start. Very quickly I realised that I didn’t want to leave the company anymore, one thing led to another and now I’m their new HR officer!


Sanne Peerebooms,
HR Officer, Brussels

I joined 3E in the pursuit to work for a diverse, challenging and leading-edge renewable energy company.

It has been a little over a year now since my onboarding and it makes me happy to say that each and everyone of those requirements has been more than fulfilled. On top of that I get to work in an amazing team together with supportive colleagues.


Arthur Ostyn,
Consultant in the Resource Assessment team, Brussels

I stumbled on 3E and it was one of the better things to happen to me. It made me more conscious about my ecological footprint in little things. The colleagues of different nationalities are also very interesting to me.

I am surrounded by many smart people and they say “surround yourself with people who inspire you”, no? Well, there you go.

I like the vibe at 3E and this since the very beginning!
