OUR STORY

Why Code Gaia exists

Niklas Schönstein and Markus Adler founded Code Gaia in 2021 with one conviction: sustainability must not smother companies in bureaucracy.

  1. The challenge

    CSRD, carbon footprint, supply chain, packaging: the requirements keep growing and changing. In many companies, only a few people take care of them, often on top of their actual job.

  2. Our approach

    Compliance as a service: software with proven blueprints, Kurt AI for the tedious work and sustainability experts who support you personally. When the rules change, the software changes with them.

  3. The result

    Your obligations are done, documented and audit-proof. And your team finally has time again for what it set out to do: the sustainable transformation of your company. Fewer spreadsheets, more impact.
