TeleSon Vertriebs GmbH Tech Stack

Energy contract brokerage platform with direct sales at scale

Consumer Services München 1,001–5,000 employees Founded 2000 Public Company

TeleSon is a public energy brokerage house managing millions of customer relationships through direct sales. The tech stack—PHP/Symfony backend with React frontend, MySQL + Redis, containerized via Docker—reflects a business built on transaction volume rather than complexity. Active projects reveal a pivot from pure brokerage toward owned products: the company is building its own digital sales platform, optimizing household tariffs, and migrating from monolith to service-oriented architecture, while simultaneously scaling door-to-door sales operations. Sales hiring dwarfs engineering (10:1), consistent with a sales-led org hitting against product scalability ceilings.
