Datree, a Y Combinator-backed startup in the Kubernetes and DevOps security industry, is shutting down after six years, resulting in the layoff of its entire team. The company, which had developed an open-source policy management solution used by hundreds of companies daily, was unable to achieve a sustainable business model despite building a strong community with over 6,000 GitHub stars. The closure was announced by founders Shimon and Eyar, who expressed gratitude to their team, customers, investors, and the broader tech community for their support throughout the journey.
