About AZX
Our mission is to accelerate positive impact in critical industries through AI transformation.
We're growing quickly and already work with category-leaders in real estate (CBRE), energy (LevelTen Energy), logistics (Flexe) and utilities (can't say which large utility yet).
We're a public benefit corporation, founded in 2024 and have been profitable from the beginning (bootstrapped with consulting).

  • Excellent communication skills with internal and client contacts

Values and Culture Qualifications
  • High emotional intelligence and a learning mindset
