ZusammenStromen

What ZusammenStromen does

ZusammenStromen GmbH is a Hamburg-based digital platform operator that intermediates the German Treibhausgasminderungsquote (THG-Quote) — a market-based regulatory mechanism obligating fuel-supplying companies to reduce transport-sector greenhouse-gas emissions. The company aggregates certified CO2 savings from electric-vehicle charging and fleet operations and markets these to quota-obligated buyers (primarily mineral-oil companies), capturing the spread as revenue.

The company operates four product lines addressing distinct customer segments: (1) THG-Quote for Ladepunktbetreiber (CPOs) — monthly per-kWh rebates of 5–15ct€/kWh (up to 40ct€/kWh for Ökostrom), integrated via Hubject's intercharge.eticket for automated data flow; (2) THG-Quote for Flottenbetreiber — annual premiums up to €400 per pure battery-electric vehicle, supported by AI-powered mass document upload; (3) THG-Quote for Firmen mit eAuto-Kunden — a four-tier B2B partner program (Affiliate, Agent, Whitelabel, API) enabling utilities, dealers, and large enterprises to integrate THG services into their own products; and (4) geld-fuer-eAuto.de — a consumer self-service platform for individual eMobilists to claim annual premiums via automated Fahrzeugschein processing.

ZusammenStromen earns revenue primarily through transaction-based commissions on certified quota trades, supplemented by affiliate/agent revenue shares. Distribution combines a digital self-service motion for individual drivers, Hubject-mediated reach into public-charging CPOs, direct enterprise sales for fleet operators, and a partner/channel model for B2B2C distribution. The company is privately held, bootstrapped, and founder-controlled (Wilko Eggers, Hilko Krüger, Joris Krüger), with no external institutional investment recorded. Strategic partnerships with Hubject, Deutsche Telekom (Tech-Booster), and the Bundesverband eMobilität (BEM) anchor its position within the German eMobility ecosystem.

Core offering

ZusammenStromen operates a digital platform that certifies CO2 emission savings from electric vehicles and EV charging infrastructure under the German Treibhausgasminderungsquote (THG-Quote) framework and markets these certified quotas to quota-obligated companies. The platform serves charging point operators, fleet operators, businesses with eAuto-owning customers, and individual eDrivers, automating document validation, certification with the Umweltbundesamt, and premium payouts.

Product overview

ZusammenStromen operates a digital THG quota trading platform with four interconnected product lines: (1) geld-für-eAuto.de — a consumer-facing online platform for individual eAuto owners to claim their annual THG premium; (2) THG-Quote für Ladepunktbetreiber — enabling charging point operators to earn rebates per kWh sold via Hubject integration; (3) THG-Quote für Flottenbetreiber — helping companies with electric fleets monetize their CO₂ savings through AI-powered document processing; and (4) THG-Quote für Firmen mit eAuto-Kunden — a partner program with four engagement models (Affiliate, Agent, Whitelabel, API) for businesses serving eAuto customers. All four products share a common digital infrastructure layer that aggregates CO₂ savings data, certifies it with German authorities, and markets the resulting THG quotas to obligated companies.
