This round is among the largest seed-stage fundraises in Poland to date, co-led by Contrarian Ventures, Market One Capital and Movens Capital. FJ Labs, Push Ventures and Aidiom also participated. The capital will support new product features to expand and improve the platform. sun.store also plans to grow its operational and commercial teams, focusing on merchant onboarding, strategic sourcing and business development. Headquartered in Warsaw, the company is currently hiring for product, engineering and commercial roles.
From manual to digital
Launched in Poland in October 2023, sun.store addresses a persistent challenge in the European solar sector: procurement remains manual, fragmented and inefficient, particularly for smaller installers, distributors and 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. “This funding gives us the resources to scale faster and expand our reach at a time when the sector needs it most.”

Bartosz Majewski, co-founder at sun.store: “We’ve been in the solar trenches long enough to know how fragmented and frustrating procurement can be. That’s why we built sun.store – to give installers, distributors and EPCs the speed and clarity they need to thrive in a market that’s only getting more complex.”
Europe’s solar and storage markets represent a €35-40 billion annual opportunity in installed component value. Components typically change hands four to five times before installation, further increasing transaction volumes and values. Yet much of this value is still traded through outdated, offline channels that lack transparency, scalability and speed.

sun.store enables verified sellers to list products with structured data, dynamic pricing and integrated logistics. Buyers – including installers, wholesalers and EPCs – can search and filter thousands of offers in real time, receive instant quotes and complete transactions with flexible payment options and embedded support.
Growing traction in a fast-changing market
sun.store has achieved the following milestones in the two years since launch:
• More than 35,000 registered users and 2,500 unique buyers from over 25 countries
• Transactions totalling 1.4 GW of photovoltaic components – enough to power a city the size of Brussels
• Over 1,000 transactions every month, with an average order value exceeding €8,000
• A network of more than 500 active sellers, collectively listing over €1.5 billion worth of components, surpassing any traditional distributor in Europe
• Access to products from more than 200 brands across over 1,000 warehouses
• Pan-European trade, with 90 percent of transactions cross-border within the EU, and no single country accounting for more than 25 percent of Gross Merchandise Value (GMV).
