Climestart

Today I’m launching Climestart, an e-learning platform for early-stage climate tech entrepreneurs and those who want become one. It has the mission to democratize climate tech entrepreneurship via access to know-how. This very first version starts with 105 lessons and exercises to take you from zero to product-market fit. You can choose how many of them you do, but you get a certificate in Climate Tech Entrepreneurship if you do at least 50 of them. There is more in the making, and early backers will get it much cheaper, since what you get is a lifetime membership (not another annoying subscription). So, if you are contemplating over becoming a climate tech or nature tech founder and need inspirational knowledge, guidance, and encouragement, check it out. Initially, Climestart was nothing but a side project keeping myself busy and creative in a challenging episode of my life. I didn’t approach it very entrepreneurial, more as a means for personal growth. That’s why I now feel proud and stupid at the same time saying that everything about the project I did myself as bootstrapping solopreneur: the content, the audio recordings, the design, even the code - well, eventually switching to vibe coding, but who doesn’t nowadays? I developed Climestart for my past self. When I first tried to break into climate tech 2.5 years ago, I faced many challenges. I read books, did online research, and attended countless events, but came out more confused. As a generalist, no path or sector felt obvious. I took online courses, which were fun but mainly suited for job seekers. I didn’t want a job - I wanted to build a company. Eventually, I landed on biodiversity and nature finance, but only after months of wandering. Looking back, my choice didn’t fully align with my skills or the market. Joining a venture builder helped - I felt like a founder again. Still, I learned the hard way that the climate tech playbook differs from traditional startups. So, with Climestart, I asked: What could have helped me back then? Nothing replaces the struggle - but better preparation would’ve made it smoother. Though I usually preach customer-first building, this time I built for myself. Because if something works for you, it’ll likely work for others like you. And you’re always there to test it.
