Sunhat Tech Stack

AI-powered proof platform for compliance and sustainability reporting

Software Development Cologne, North Rhine-Westphalia 51–200 employees Founded 2022 Public Company

Sunhat automates the assembly of compliance and sustainability evidence—policies, certifications, reports—by connecting to systems where data already lives and refreshing them continuously. The tech stack (TypeScript, Angular, Nest.js, Claude, Gemini, Mistral, Llama, RAG) reflects a modern AI-native architecture, with heavy investment in LLM ops and agentic workflows. Hiring is heavily skewed toward sales and marketing (7 of 9 open roles) while engineering remains minimal, signaling a product-market fit validation phase where revenue growth and geographic expansion (DACH, Europe) now outpace engineering velocity.
