thermondo Tech Stack

Digital heat pump and solar installation for residential energy transition

Renewable Energy Semiconductor Manufacturing Berlin, Deutschland 1,001–5,000 employees Founded 2013 Public Company

thermondo operates a tech-enabled installation business for residential heat pumps, solar systems, and EV chargers across Germany. The stack reveals a services-delivery org: Salesforce + Looker for customer and field operations, custom software in Python/Node/TypeScript/Vue, and mobile-first tooling (Kotlin Multiplatform, iOS/Android). The hiring mix is heavily weighted toward engineering (127 roles) relative to sales (29), suggesting the company is automating field operations and customer workflows rather than scaling sales headcount — a pattern reinforced by pain-point data (streamlining installation, reducing paperwork, legacy manual work).
