Simplify's Take

What believers are saying

  • BayWa r.e. selected SynaptiQ for strategic PV and BESS assets in 2024.
  • Everday used SynaptiQ on a 1.6 GWp portfolio, validating enterprise-scale operations.
  • 3E added IZEN in June 2026 and launched SynaptiQ project development in September 2026.

What critics are saying

  • 3E depends on renewables capex cycles; project pauses hit consultancy revenue immediately.
  • SynaptiQ still needs renewals from BayWa r.e., Everday, and IZEN in 2026-2027.
  • A larger platform vendor can bundle monitoring, ERP, and compliance, compressing 3E margins.

What makes 3E unique

  • SynaptiQ combines AI analytics with physics-based digital twins for solar, wind, and storage.
  • 3E couples software with consultancy, supporting projects from feasibility through operations.
  • ISO 17025 accreditation strengthens wind measurement credibility versus generic monitoring vendors.
