Sun Store is a Poland‑based B2B digital marketplace that digitizes procurement for the European solar and storage supply chain, enabling installers, distributors, wholesalers and EPCs to discover, price, buy and track PV components and batteries from verified sellers in real time[1][3]. The company launched in 2023 and has rapidly scaled merchant and buyer adoption across Europe, raising a €6M seed round to accelerate product development, merchant onboarding, logistics and go‑to‑market expansion[1][3].
High‑Level Overview
- Mission: To bring structure, speed and transparency to solar procurement by creating a professional, transactional marketplace for PV components and storage across Europe[3][6].[3]
- Investment philosophy / business model (for this portfolio company): A transaction‑first B2B marketplace that earns revenue from marketplace transactions and value‑added services such as integrated logistics, financing (e.g., Buy‑Now‑Pay‑Later) and procurement support[1][2][3].[3]
- Key sectors: Solar PV modules, inverters, batteries and adjacent clean‑energy hardware with a longer‑term aim to expand into other clean‑energy equipment categories (HVAC, heat pumps, e‑mobility infrastructure, electrical components)[1].[1]
- Impact on the startup / industry ecosystem: By digitizing previously manual, fragmented procurement workflows (emails, spreadsheets, ad hoc negotiations), sun.store reduces transaction friction, widens market access for merchants across borders, improves price transparency and speeds project delivery—benefits that help installers scale and can lower soft costs across the European solar market[1][3][6].[1]
Origin Story
- Founding year and team: sun.store was founded in 2023; public reporting names Agata Krawiec‑Rokita as CEO and Bartosz Majewski as co‑founder, and positions the company as Warsaw‑based[3][1].[3]
- How the idea emerged: The founders built sun.store to address endemic procurement pain points in solar—manual processes, opaque pricing and multi‑party logistics—by creating a structured, transactional marketplace where verified sellers list products with standardized data and buyers can obtain instant quotes and complete purchases[1][3].[1]
- Early traction / pivotal moments: By the seed round announced in 2025, sun.store had built a multi‑market merchant and buyer network (platform claims thousands of users and gigawatts of available product in public materials) and secured €6M from co‑lead investors Contrarian Ventures, Market One Capital and Movens Capital to scale product and commercial teams[2][1][3].[2]
Core Differentiators
- Structured product data and dynamic pricing: Sellers list components with standardized specifications and dynamic pricing so buyers can compare like‑for‑like offers across vendors in real time[1][3].[1]
- Verification and trust mechanisms: Platform verifies counterparties and supports secure transactions (including escrow/payment rails), reducing risk of mismatches and failed deliveries[1][6].[1]
- Integrated logistics and financing: Built‑in logistics coordination and payment flexibility (e.g., Buy‑Now‑Pay‑Later) target the cashflow and fulfilment pain points of installers and EPCs[2][1].[2]
- Pan‑European marketplace focus: From day one sun.store has aimed for cross‑border scale across Europe, enabling merchants to reach new markets and buyers to source beyond local suppliers[3][6].[3]
- Vertical focus and extensibility: Starting with solar and storage but designed to expand into adjacent clean‑energy equipment categories, giving it a path to capture more of the clean‑energy hardware stack[1].[1]
Role in the Broader Tech Landscape
- Trend alignment: sun.store rides several converging trends—digitalization of B2B procurement, marketplace economics for long tail industrial supply, electrification of energy systems, and rapid growth of distributed solar and battery installs across Europe[1][3].[1]
- Why timing matters: Europe’s component market for solar and storage represents tens of billions in installed components annually and still relies heavily on offline, fragmented workflows; digital marketplaces can therefore unlock large efficiency gains and net‑new scale now as installation demand grows[1].[1]
- Market forces in its favor: Rising deployment of rooftop and distributed solar, supply chain complexity that favors platform orchestration, and investor appetite for marketplaces in industrial verticals support sun.store’s expansion[1][3].[1]
- Influence on ecosystem: By lowering procurement friction, the platform can reduce soft costs, shorten project timelines, and enable smaller installers to compete—potentially accelerating solar adoption and fostering more professional distribution channels across countries[1][3].[1]
Quick Take & Future Outlook
- Near term: Expect sun.store to focus on scaling merchant onboarding, deepening logistics and financing features, and widening product assortment across Europe following its €6M seed raise[1][3].[1]
- Medium term: If successful, sun.store could expand beyond core PV and batteries into other clean‑energy hardware (heat pumps, EV chargers, electrical components), becoming a broader vertical marketplace for energy hardware—increasing TAM and stickiness via procurement services and financing[1].[1]
- Risks & challenges: Marketplace network effects require rapid two‑sided growth; margins in hardware distribution can be thin; cross‑border VAT, warranty and logistics complexity across EU markets are operational hurdles to scale[1][3].[1]
- Strategic upside: By standardizing product data, offering financing and logistics, and verifying counterparties, sun.store can capture a larger share of transaction value and create defensibility through merchant relationships and embedded services[1][3].[1]
Quick final link back: sun.store positions itself as a pragmatic digitizer of a bulky, offline supply chain in European solar—if it continues to win both sellers and installers, it can materially reduce procurement friction and broaden access to clean‑energy projects across the continent[1][3].[1]
