Matthieu Vaxelaire
I joined eFounders in 2012 as a partner, where I had the privilege of helping launch unicorns like Front (HX14) and Aircall (HX14). I then led Mention as CEO (HX13), taking it all the way to acquisition and co-founded Colette.club. In 2022, I returned to Hexa as a Partner, I am passionate about launching several companies at a time and working with ambitious entrepreneurs.
I love helping founders bring their visions to life by generating ideas, shaping market positioning, and guiding strategic direction. I’m here to help navigate critical business decisions, secure key partnerships, and connect with top-tier investors. At Hexa, I’ve supported startups in raising funds in record time with backers like LocalGlobe, Point Nine, and Frst. For me, there’s nothing more rewarding than helping ambitious founders turn bold ideas into thriving businesses.
Outside of work, I’m passionate about triathlons — so much so that I’m organizing one! That said, I still can’t swim crawl to save my life.
Exothermic energy—that’s what I call the type of energy that inspires and unites, and it’s exactly what I look for in founders. As a founder, your ability to excite investors, clients, and teams is critical. It’s simple: if I leave a conversation with you feeling more energized than when I walked in, I know you have what it takes.
I also value those who combine speed with reflection—those who move fast, take decisive action, and consistently seek feedback. The ones who can push the tempo while asking, “How can I improve?” at the end of the week are the ones who stand out.
From my experience as an entrepreneur and working alongside founders, I’ve learned that entrepreneurship is an all-encompassing journey. While it may offer more flexibility than the gruelling careers of investment banking or consulting—making it possible to balance being a parent—it still demands a profound level of commitment. I look for founders who not only understand this intensity but are fully prepared to embrace it.
