About the Company

Founded in January 2025, Ocean Orchestra aims to be a force for good in ocean conservation and the ocean economy. Backed by leading SaaS, FinTech and Climate investors, this is an opportunity to apply modern tech to a huge global challenge. Oceans are 71% of our planet and central to climate health, yet receive only a fraction of the world’s investment, technology, and AI innovation. Ocean Orchestra is changing that.

Our founding team — Jeremy King , Simana Paul and others [we can happily introduce the other co-founder live; she’s amazing] — have built businesses to global scale. Now, we’re focused on creating lasting, positive change for our planet.

Equity: Real ownership, significant upside potential.
