Sunhat

Sunhat is a B2B SaaS company that has built the Collaborative Proof Platform — enterprise software designed to transform how companies manage and share sustainability data with internal teams and external stakeholders. Founded in 2022 by Lukas, Ali, and Alex, Sunhat addresses the 'proof gap' between rising ESG demands and companies' ability to deliver trustworthy, audit-ready documentation. The platform supports EcoVadis assessments, CDP disclosures, ISO certifications, CSRD/ESRS reporting, VSME compliance, PPWR regulatory compliance, and third-party risk screening. Using AI-driven automation, Sunhat helps sustainability teams collect data from existing sources, generate context-based responses to questionnaires and certification requests, and produce structured audit-ready results. The platform serves manufacturers, brand owners, enterprises, and finance/IR teams. In September 2025, Sunhat raised €9.2 million in Series A funding. The team comprises 60+ employees across 7+ nationalities with over 50% women in technical roles.
