The Ocean's Billion-Ton Carbon Removal Opportunity | Gigablue

<p>What if the cheapest, largest carbon removal machine on Earth isn&#39;t a factory, but phytoplankton in the ocean?</p><p>Company bio:</p><p>Gigablue is building MCFS (Microalgae Carbon Fixation and Sinking), a marine carbon removal method that uses phytoplankton and carbon carrier pods to capture and store carbon in ocean sediment. They recently raised a $20M Series A to scale their work. </p><p>Speaker bio:</p><p>Ori Shaashua is the co-founder of Gigablue and a serial technology entrepreneur, investor, and executive with a multi-sector track record across artificial intelligence, climate tech, cybersecurity, digital health, and smart mobility.</p><p>Five lessons for climate entrepreneurs:</p><ul><li>Build for the real bottleneck, not the obvious one – In carbon removal, the challenge wasn’t just capturing carbon; it was exporting it durably. Great founders identify the true constraint and design around it.</li><li>Trust is part of the product – In a market that depends on verification, transparency, and public credibility, open methodology and measurable outcomes become strategic advantages.</li><li>Use the business model buyers already understand – Gigablue borrowed contract structures from commodity and energy markets, making it easier for large buyers to transact with confidence.</li><li>Scale requires timing, not just ambition – Ori emphasized that the market is moving from experimentation to consolidation, and that entering at the right stage can lower risk for both founders and buyers.</li><li>Tie the mission to durable economics. – A climate solution has to make financial sense, not just scientific sense. The strongest ventures are built where impact and commercial viability reinforce each other.</li></ul><p><br></p><p>--</p><p><br></p><p><strong>1️⃣ Join our confidential CEO community.</strong></p><ul><li>Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.
