About the company

Reonic provides a software platform that helps installers manage the entire lifecycle of renewable energy projects, including solar panels, heat pumps, and electric vehicle charging stations. The software works by combining technical planning tools, such as roof layouts and energy simulations, with business tasks like lead management and digital contract signing into a single interface. Unlike competitors that require multiple separate programs, Reonic integrates a database of over 100,000 components to allow installers to design and document complex, multi-technology energy systems in one place. The company's goal is to increase the efficiency of installation businesses to accelerate the adoption of sustainable energy infrastructure across Europe.

Simplify's Take

What believers are saying

  • Northzone led Reonic's €13 million Series A in September 2024, funding expansion.
  • Reonic added Berlin, Augsburg, and São Paulo hiring, with 29 open roles in August 2026.
  • Recent 2026 listings for UK, Italy, France, and Netherlands roles show active geographic expansion.

What critics are saying

  • OpusFlow, Sollit, and OpenSolar crowd the same installer workflow category in 2026.
  • Reonic still depends on small installer SMB budgets, making churn brutal during slow sales cycles.
  • If AI agents disappoint, Reonic becomes a feature bundle against larger vertical software suites.

What makes Reonic unique

  • Reonic bundles CRM, design, proposals, scheduling, and grid registration for installers.
  • Its product spans solar, storage, EV charging, and heat pumps in one system.
  • Reonic claims 3,000 business customers and an AI operating system positioning.
