VREY

Turnkey communal solar energy for buildings

Overview

VREY (RE Joule GmbH) is a Berlin PropTech firm that provides solar power solutions for multi-family buildings. It plans, installs, and operates photovoltaic systems and runs the administrative side through a digital platform that automates billing to tenants under §42b EnWG, acting as a metering point operator. Landlords can sell solar power directly to tenants, while the platform handles contracts with energy providers for any remaining electricity, reducing supplier obligations and potentially lowering tenant costs and increasing property value. The goal is to expand communal solar use, support building decarbonization, and grow the value of rental properties by enabling tenant-verified clean energy.

Simplify's take

What believers are saying

  • On April 23, 2026, VREY raised €3.3 million from Rubio, HTGF, and Kopa.
  • VREY reported a three-digit project base across Germany's 16 federal states by April 2026.
  • Germany's communal building supply rules unlock apartment solar, and VREY operationalizes them.

What critics are saying

  • VREY depends on §42b EnWG; regulatory changes break its core workflow by 2027.
  • Large utilities like E.ON and regional metering incumbents can compress VREY's margins.
  • If landlord adoption slows after the April 2026 seed, VREY becomes a niche contractor.

What makes VREY unique

  • RE Joule GmbH bundles metering, billing, and installation for §42b EnWG communal supply.
  • VREY turns multi-family roofs into tenant electricity businesses without landlord supplier liability.
  • Founded in 2024 by Julius Pahmeier and Cedric Jaeger, VREY targets apartment buildings exclusively.

VREY raises $3.7M to bring solar power to urban multi-family buildings

Berlin-based startup VREY has secured €3.3 million in seed financing to scale its solar power solutions for multi-family homes. The company specialises in bringing photovoltaic systems directly to urban residential buildings. VREY is already active in over 200 buildings, demonstrating early traction in the multi-family housing sector. The funding will support the company's expansion efforts as it works to increase solar power adoption in urban residential properties. The investment highlights growing interest in decentralised renewable energy solutions for apartment buildings, where traditional solar installations have historically been more challenging to implement compared to single-family homes.
