What Reconcept does

Reconcept GmbH is a Hamburg-based, owner-managed financial services and renewable energy project developer founded in 1998. The company originates and asset-manages green investment products, primarily exchange-tradable (depotfähig) Green Bonds and inflation-protected bonds issued under German capital-markets frameworks, and connects these to its own pipeline of wind, solar, hydro and tidal energy projects across Germany, Finland, Canada and (since June 2026) Spain. As of end-2025 Reconcept reports EUR 685 million in cumulative investment volume placed with 16,000+ private investors, approximately 390 MW of realized renewable capacity across 240 plants, and a development pipeline of roughly 10 GW including German wind, Finnish wind and hydrogen, Canadian tidal and Spanish solar-plus-BESS projects.

The operating model is an integrated two-sided platform. On the project-development side, Reconcept identifies sites, negotiates land leases with landowners, runs permitting and construction, and delivers ready-to-build or operational renewable assets to its own portfolio or to buyers; on the capital side, it acts as issuing house for fixed-interest bonds (6.5-7.75% p.a., 5-7 year tenors, ISIN-registered and listed) and provides ongoing commercial and technical asset management. Revenue derives from issuance fees, recurring asset management fees on the EUR 685M AUM, project development fees and equity participation in projects, supplemented by a sales-partner (Vertriebspartner) distribution network and direct online subscription via its investor portal.

The company is led by Managing Partner Karsten Reetz (with the firm since 2006) alongside Managing Director Christiane Kaufholt-Mecke, and operates through wholly-owned subsidiaries in Canada (reconcept RE Canada Ltd.), Spain (reconcept Iberia S.L.), Germany (reconcept consulting GmbH, reconcept Treuhand GmbH), and a Finnish joint venture (Tuulialfa Oy) that grants it contractual right of first refusal on approximately 3,400 MW of Finnish wind. Technology differentiation is concentrated in the FORCE 1 tidal power platform deployed with Sustainable Marine Energy in the Bay of Fundy, while onshore wind and solar use established turbines from Vestas, Nordex and Enercon. Headcount sits in the 11-50 range and the company is privately held with no parent company or external PE/VC backing disclosed.
