Halcyon’s Climate vertical empowers entrepreneurs creating solutions that strengthen adaptation and resilience for communities and ecosystems to face climate change.
At Halcyon, we design our programming around the specific needs of adaptation and resilience founders. Our skill series and office hours focus on topics like climate and blended financing for adaptation, non-dilutive funding and grant writing, impact and resilience metrics, financial modeling and go-to-market strategies for climate solutions, and business development for sectors such as clean energy resilience, nature tech, and water and coastal systems. We work with investors, multilaterals, corporate partners, and technical experts focused on climate adaptation and resilience to help founders understand financing pathways, policy and regulatory contexts, and route-to-market opportunities for solutions that protect communities and ecosystems.
Sub-Sectors
Climate-resilient infrastructure and built environment (e.g.., hurricane-resistant materials, flood-proofing systems, cool roofs and passive cooling, stormwater drainage solutions, climate risk tools for real estate, modular housing)
Disaster preparedness and emergency response (e.g., early warning systems, rapid damage assessment tools, drones for mapping, community preparedness apps)
Adaptation finance and data intelligence (e.g., climate risk analytics, resilience scoring tools, adaptation investment platforms, impact measurement tools)
Climate insurance and risk transfer (e.g., parametric insurance, micro-insurance for farmers and fishers, risk pooling models, embedded insurance solutions, climate underwriting tools)
Agriculture and food security (e.g., climate-smart agriculture tools, drought-resistant crops, hydroponics and greenhouse systems, regenerative farming, irrigation technology, post-harvest storage, local food processing)
Community and social resilience (e.g., climate workforce training, climate migration support platforms, resilient tourism models, localized supply networks)
Water resilience and water tech (e.g., rainwater harvesting, decentralized water purification, desalination innovation, leak detection systems, watershed monitoring, floodwater capture and reuse)
Energy and grid resilience (e.g., solar and battery systems, community microgrids, energy storage innovation, demand management platforms; resilient power for critical facilities)

ADAPTA Inc.
ADAPTA develops climate risk management products for financial intermediaries. Its 1st MVP, the ADAPTA Climate Score (CS), was developed and tested over 24 months as proof of concept. The product has been rolled out in Kenya, and is planed to roll it out in East Africa, the US, and Mexico in 2024. CS leverages biodiversity, climate, soil, and water data. The CS is analogous to a credit score using past data to forecast future risk. It was developed in discussions with six banks and is being tested by three banks before going commercial in early 2024. ADAPTA is beginning to develop a new product, “the digital portfolio system,” which will provide lenders and borrowers with satellite imaging, weather, and NDVI data.

Coral Vita
Coral Vita helps to restore our world’s dying reefs by growing corals on land and transplanting them into dying/endangered reef ecosystems. Coral reef ecosystems support 500M people and generate $30B annually, but 75% are projected to die by 2050. Coral Vita’s innovative farming system can grow coral at up to 50x natural rates while enhancing the corals’ resiliency to climate change.

Climate Impact
Halcyon defines and evaluates ventures based on their measurable impact in climate adaptation, which refers to meaningful adjustments in ecological, social, or economic systems made in response to actual or expected climate impacts. These adjustments aim to reduce vulnerability and build resilience by increasing access to climate adaptation interventions, such as improved infrastructure, access to early warning systems, resilient agriculture practices, water management solutions, and more.
