ROCKSOLID Baufinanzierungen & Finanzen

What ROCKSOLID Baufinanzierungen & Finanzen does

ROCKSOLID GmbH, operating as ROCKSOLID Baufinanzierungen & Finanzen, is an independent German mortgage and financial advisory broker headquartered in Karlsruhe, Baden-Württemberg, with additional branch offices in Mannheim and Stuttgart. Founded in 2004 and registered under HRB 750304, the firm is held by two managing directors, Dennis Haug and Marius Göbel, and operates as a licensed Darlehensvermittler (§34c/§34i GewO) and insurance broker (§34d GewO) under IHK Karlsruhe supervision. Its core function is intermediating Baufinanzierung, Ratenkredit, and Versicherungen products on behalf of individual consumers, comparing offerings across a network of 800+ bank partners and the major German mortgage aggregator platforms (Europace, Ehyp, Baufinex, Forum, Finlink) to source competitive terms for each customer.

The company runs a hybrid advisory model: free digital self-service tools (Finanzierungsrechner, Zinsrechner, Budgetrechner, Zinsbindungsvergleich, Kundenportal) sit alongside in-person Beratung at three branches and remote consultations via video, phone, and WhatsApp. A 5-step financing request process routes customers from inquiry to disbursement, with the OneClick Baufinanzierung sub-product offering a binding financing commitment for qualified borrowers. Internally, the technology stack is composed of standard SaaS — Google Analytics 4, Hotjar, PostHog, Make, Zapier, Calendly, and so on — with no proprietary fintech platform disclosed. The Vertriebspartner program recruits self-employed sales agents who originate loans through ROCKSOLID's bank network, adding a B2B2C origination layer on top of the direct advisory team.

Revenue is generated through commissions (Vermittlungsprovision) from bank partners on successfully placed loans and insurance policies, rather than through direct customer fees. Reported scale signals include 3,000+ loans facilitated over the company's history and 1,000+ verified customer reviews on ProvenExpert at 4.9/5 stars. The firm is privately held, reports no external funding, and operates with approximately 8 employees. Geographic scope is regional within Baden-Württemberg, with no evidence of international expansion or digital scale beyond the German market.

Revenue model

1. Loan/Financing Commission (Darlehensvermittlung): ROCKSOLID earns commissions (Vermittlungsprovision) from its network of 800+ bank partners when it successfully places mortgage loans or other financing products with customers. The company acts as an independent intermediary (Darlehensvermittler) under §34c/§34i GewO, comparing offerings across its partner bank network to find optimal conditions for each customer. Revenue is generated on a per-transaction basis, driven by the volume and value of financed loans originated through the platform. This is the primary revenue stream.
2. Insurance Brokerage Commission (Versicherungsvermittlung): ROCKSOLID also sells insurance products (Versicherungen) as a licensed insurance broker (§34d Abs. 1 GewO), earning commissions on insurance policies placed with carriers. This is a secondary revenue stream complementing the core mortgage advisory business.
