A Malagasay start-up has won a share of $150,000 at the Blue Carbon Plus Challenge in Singapore during Regenerative Ocean Week 2025. Mena Tsook took the win in the Pilot Phase category organised by Hatch Blue with her innovative cosmetic and wellness products that sustainably harness marine resources.
Mena Tsook is the brainchild of Sarobidy Rakotonjatovo and uses sea urchins which have proliferated and threaten the delicate sea grass ecosystem of the Indian Ocean coastline around the country. She takes up the story:” I started Mena Tsook as a way to contribute to ecological balance. Sea urchins, while valuable, have become invasive in certain areas, threatening local marine biodiversity. By turning them into a resource, we’re helping both the environment and local communities. Plus, sea urchin roe is naturally rich in lipids and nutrients, making it a healthy and gourmet ingredient.”
Mena Tsook was helped to bring her project to life with support from AfroClimate, a dynamic organisation dedicated to supporting social innovators in the climate sector. “AfroClimate has been a valuable support in the development of my startup. Their mentorship has helped me grow not only as a founder, but also as a leader. With their guidance, I’ve been able to shape my vision and improve the financial, marketing, and operational management of my project. What I truly appreciate is their energy — they keep us active, push us to take action, and turn ideas into reality. Their commitment to African entrepreneurs is truly inspiring, and I’m deeply grateful for their support.”
