Polish startup sun.store raises €6M to scale Europe’s largest B2B solar marketplace

sun.store, a B2B digital marketplace for solar components, has raised €6 million in seed funding to accelerate its mission of transforming how solar, PV and battery index equipment is sourced and traded across Europe. The startup shared the details with AIN.

• According to the company, the round is one of the largest seed-stage fundraises in Poland to date.
• The round is co-led by a plethora of Baltic and Polish VC funds, including the likes of Contrarian Ventures, Market One Capital and Movens Capital.
• FJ Labs, Push Ventures and Aidiom also participated in the round.

sun.store was launched in October 2023 to solve a critical challenge in the European solar industry – procurement remains manual, fragmented, and inefficient – particularly for smaller installers, distributors, and engineering, procurement and construction (EPC) firms. 

“Our goal is simple – to bring structure, speed, and transparency to solar procurement,” said Agata Krawiec‑Rokita, co-founder and CEO of sun.store. “We’ve built a transactional B2B platform tailored to the workflows of the solar industry – not just another listings site or generic marketplace. This funding gives us the resources to scale faster and expand our reach at a time when the sector needs it most.”

The fresh funding will be used to accelerate development of new product features to expand and enhance the platform.

sun.store also plans to expand its operational and commercial teams, with a focus on merchant onboarding and support, strategic sourcing, and business development. The company operates from Warsaw and is currently hiring for product, engineering, and commercial roles.
