Environmental Services Petit-Lancy, Suisse 51–200 employees Founded 2005 Nonprofit

Gaea21 is a Swiss nonprofit operating as a sustainability intermediary and training provider. The tech stack reveals a research-to-delivery operation: heavy use of Python, R, and data tools (Power BI, Pandas, PostgreSQL) for impact measurement, paired with web frameworks (React, Angular, Vue) for public-facing platforms. The hiring profile is heavily skewed toward research (29 roles) and marketing (16), with 59 interns — typical of mission-driven orgs scaling program delivery and public engagement rather than scaling engineering.
