The HEAT whitepaper, produced by venture‑capital firm PT1 in partnership with DWR eco (April 2026), makes the case that climate‑adaptation technologies (AdaptationTech) represent a high‑growth, double‑return investment opportunity. It begins by highlighting that the Paris 1.5 °C target has already been exceeded and that climate impacts—heatwaves, floods, droughts, and related economic losses—are accelerating, especially in Europe. The paper quantifies a global adaptation finance gap of roughly €1.1 trillion per year and shows that only about €63 bn is currently invested, leaving a 17‑fold shortfall. It argues that this gap is partly due to a weak growth‑stage VC market in Europe and the historic focus on mitigation rather than adaptation. The authors map the regulatory landscape (SDGs, Paris Agreement, EU Climate‑ADAPT, German Adaptation Strategy, Climate‑Adapt Act, CSRD, etc.) and argue that Europe’s advanced policy framework makes it an ideal hub for an AdaptationTech ecosystem. The core of the paper categorises AdaptationTech solutions for the built environment into data & software, disaster response, water management, smart infrastructure, and climate‑resilience FinTech/InsurTech, describing the required digital foundations (IoT, AI, satellite data) and the market segmentation by technical complexity and public vs. private customers. A series of concrete startup case studies (e.g., Satelitte Vu, ICEYE, Climate‑X, FloodFlash, Vialytics, Groundhawk, PYDRO, etc.) illustrate business models, revenue streams, and traction. The finance chapter reiterates the €1.1 tn gap, translates a 4 % share for AdaptationTech into a €44 bn annual VC opportunity, and points out the dominance of public funding and the under‑investment in growth‑stage capital. The final chapter urges policymakers to embed adaptation in procurement, public‑private partnerships, and regulatory incentives, and advises investors to act now to capture the “sunrise” phase, benefit from low valuations, and achieve both financial returns and societal impact. The paper concludes with actionable recommendations for startups (scalable, B2G competence, strategic alliances) and investors (first‑mover advantage, dedicated AdaptationTech funds).
