About Event

Join us for this year's Ray of Hope Accelerator Demo Day. A 90-minute interactive showcase of ten startups using nature’s strategies to solve some of the world’s most urgent challenges. After six months in our accelerator, these founders are ready to share how biomimicry is shaping the future of energy, materials, water, biodiversity and more. Come prepared to ask questions and dig in. 

You’ll Meet: 

  • Anew Material: Coatings inspired by natural adhesion strategies 

  • Ecotune: Bio-inspired next-generation materials 

  • Emboa Medical: Catheters inspired by the boa constrictor’s fang 

  • Limax Biosciences: Surgical adhesives inspired by slug mucus 

  • New Dawn Bio: Cultured wood grown from tree stem cells 

  • OptionV Energy: Vanadium mining inspired by the Amanita mushroom 

  • Parsons Kinetics: Wind turbines inspired by the Triplaris americana seed 

  • PolyGone Systems: Microplastic filters inspired by floating plant roots 

  • Praio: Protocells for efficient and sustainable biomanufacturing 

  • Pyri: Wildfire detection devices inspired by Serotinous pine cones 


The Ray of Hope Accelerator is a six-month initiative of the Biomimicry Institute that supports early-stage, nature-inspired startups developing regenerative solutions to global environmental challenges. Made possible through the support of the Ray C. Anderson Foundation, the program provides non-dilutive funding, tailored mentorship, impact and sustainability business training, storytelling support, and access to a global network of experts, investors, and partners to help founders strengthen and scale their biomimicry-driven innovations.
