What Wiwin does

Wiwin (wiwin GmbH) is a German digital crowdinvesting platform headquartered in Mainz and registered in Gerbach that connects private investors with sustainable projects. It operates exclusively under the regulatory umbrella of Concedus GmbH in Nuremberg as a contractually bound intermediary (vertraglich gebundener Vermittler) under § 3 Abs. 2 WpIG, mediating financial instruments including equities (Aktien), bonds (Anleihen), and subordinated loans (Nachrangdarlehen) for renewable energy, sustainable real estate, green startups, and female-led finance initiatives across Germany.

The platform's underlying technology is a self-serve web portal (wiwin.de) with a proprietary Impact Scoring methodology that screens every project against ecological, social, and economic criteria before listing. The technical stack includes identity and tokenization integrations with Cashlink Technologies and crypto custody through Tangany for digital-asset investments, plus a partner integration with Inyova that offers algorithm-driven personalized impact-investing equity portfolios. Distribution is driven by content marketing via the WIWIN Magazine, an email newsletter, and an active presence on Facebook, Instagram, LinkedIn, YouTube, and XING.

Wiwin earns revenue through transaction-based fees on the financial instruments it mediates. Its customers are retail/private investors seeking ESG-aligned opportunities with smaller minimum amounts, while its suppliers of deals are sustainable project developers and impact startups. The firm employs 11-50 people and has been operating since 2016, with member affiliations in Bundesverband Nachhaltige Wirtschaft and Digital Invest Germany and consecutive BankingCheck "sehr Gut" ratings in 2023 and 2024.

Direct peers

• Companisto: Germany's largest equity-crowdfunding platform, enabling private investors to buy equity in startups. Comparable as a regulated German crowdinvesting intermediary serving retail investors, though broader in sector focus than Wiwin's sustainability-only mandate.
• Seedmatch: Berlin-based equity-crowdfunding platform operating under a BaFin-registered tied-agent structure. Directly comparable in regulatory model (WpIG) and retail-investor intermediation, though it is sector-agnostic rather than sustainability-only.
• bettervest: German crowdinvesting platform focused specifically on energy-efficiency and sustainability projects. Closest thematic peer to Wiwin, both serving retail investors seeking measurable sustainable impact through regulated project-based investments.
• ecoligo: Frankfurt-based solar-finance platform offering crowdinvested solar projects in emerging markets. Comparable in sustainability-aligned renewable-energy investment intermediation, though it operates a more globally distributed project pipeline.
• Inyova: Swiss-German digital impact-investing platform using algorithms to build personalized equity portfolios based on impact themes. Comparable as an impact-investing partner brand serving sustainability-oriented retail investors, although the underlying product (liquid portfolios vs. project deals) differs from Wiwin's core.
• LeihDeinerUmweltGeld: Austrian crowdinvesting platform dedicated to ecological and sustainable projects. Comparable as a German-language, sustainability-only retail-investment intermediation platform serving the broader DACH region.
• aescuvest: German crowdinvesting platform focused on healthcare ventures, operating under a BaFin-registered tied-agent model. Comparable in regulatory structure and retail-investor intermediation, though vertical-specialized in healthcare rather than sustainability.
• Exporo: Hamburg-based crowdinvesting platform historically focused on real-estate and renewable-energy projects for retail investors. Comparable as a regulated German platform mediating project-based investments to retail audiences, with overlapping asset classes in real estate and renewables.

Broad incumbents

• GLS Bank: Germany's leading sustainable cooperative bank offering sustainable deposit, investment, and financing products. Comparable as a broad incumbent in the German sustainable-finance space competing for the same impact-oriented retail capital, though via traditional banking products rather than crowdinvesting.
• Triodos Bank: European sustainable bank operating in Germany with deep expertise in financing renewable energy and sustainable real estate. Comparable as an incumbent channeling private capital into sustainability, but through regulated banking products rather than crowdinvesting.
