What founders say

  • "I expected the acceleration program to be quite messy and not very interesting, especially considering all workshops available this year online. Instead it was the opposite experience. After the 6 months I really feel, as a first time co-founder, that I have a full picture, and an understanding from all angles"
    • Maarja Meitern - Co-founder & COO
  • "By attending the Rockstart Smart Energy program we mostly reduced our time to market, not only by meeting with expert mentors to fine tune the business plan but also by having the right warm intros into key customers and the right investors. I particularly remember the speed of relevant things happening."
    • Pedro Pinto - CEO
  • "Besides the fundamentals (mentoring, workshops, networking) Rockstart has been and remains to be very helpful in fundraising. Their wide network in energy venturing has helped us find the right investor and their experience in start-up funding ensured setting up a deal structure that was right for everyone."
    • Hubert Penn - CEO
  • "Rockstart was a game changer since it helped us unlock value that would have been very hard for us to reach. Firstly, senior mentors from different backgrounds helped us as an advisory board. Secondly, we were part of a great network: we closed a sales contract with a utility company and signed an investment agreement. Last but not least, working with top tier startups was very enriching - I didn’t expect to learn so much from one another."
    • Joan Collel - CEO


The innovations driving the energy transition represent a major opportunity for agile, tech-focused startups. The top-down, centralized fossil fuel system is being disrupted by decarbonized, digitized and decentralized models, offering clean, renewable, and local energy solutions for energy intensive sectors. These solutions are central to slowing down the pace of climate change.

Old and new energy cost curves are now crossing and will diverge, driving and accelerating massive structural change. We target European businesses (see also FAQ’s) whose success will drive significant societal impact. The three areas we are interested in are:


    Integrating, exploiting and optimizing the increasing renewable energy supply to ensure a clean, reliable and sustainable energy infrastructure.


    Tackling energy intensive sectors and helping market players to avoid, reduce or offset their carbon footprint and get closer to the net-zero transition.


    Creating value from the increasing mobility data to unlock transport electrification opportunities and help cities become smarter.
