Insurance New York 1,001–5,000 employees Founded 2015 Public Company

Lemonade is a public insurtech company operating across renters, home, pet, car, and life coverage with 2M+ customers in the US, UK, and Europe. The tech stack reveals a modern, data-heavy organization: TypeScript + NestJS on the frontend, Python + R + SQL for modeling, Kafka + RabbitMQ for event streaming, and OpenAI + Claude + vector DBs (Pinecone, Weaviate, pgvector) for AI-driven underwriting and claims. The hiring mix skews heavily toward engineering, product, and data roles—reflecting a company investing in pricing optimization, fraud detection, and real-time claims automation rather than sales-led growth.
