#230 This Founder Built a $5M Climate Tech Startup in Africa (Here’s How!) w/ Martin Freimuller (Octavia Carbon)
Martin Freimüller, the CEO and Co-Founder of Octavia Carbon, a cutting-edge Direct Air Capture (DAC) company based in Kenya
Martin’s journey began with a deep appreciation for Africa’s potential and the realization that Kenya, with its abundant geothermal energy and skilled talent pool, is the perfect location for DAC. In just two and a half years, Octavia Carbon has developed patented technology, grown to a team of 61 (40 of them engineers), and even built Kenya’s first DAC pilot facility.
Here’s the kicker: they’ve managed to secure millions in prepaid carbon revenue to fund their projects — all before raising their $5M seed round. Octavia’s tech pulls CO2 from the air, stores it underground as minerals, and leverages Kenya’s unmatched renewable energy resources to make the process both cost-effective and scalable.
Reliable and affordable carbon removal is critical to the fight against climate change, and Octavia Carbon is showing that emerging markets can lead the charge.
