Interlead Gmbh

What Interlead Gmbh does

Interlead GmbH is a German B2B2C customer acquisition platform founded in 2013 and headquartered in Bremen, Germany. The company operates an AI-supported technology platform called Leadbase® that mediates qualified consumer leads, appointments, and orders between interested end-consumers (homeowners seeking complex products and services) and a network of 3,000+ registered B2B partner companies across verticals including solar/energy, real estate, insurance, finance, healthcare, home services, retail, and education. Consumer demand is captured through Interlead's owned network of specialized themed portals (the first of which, Hausfrage, launched in 2018) and through data-driven performance marketing across 10+ channels; the platform reportedly drives 35 million annual portal clicks and delivers roughly 1 million leads per year, with 30,000+ qualified purchase prospects per month and 4 million+ lifetime leads since founding.

The core product suite is built around Leadbase and four configurable lead delivery models (Multi-Leads, Exklusiv-Leads, Live-Leads, and Terminleads/Appointment leads), allowing partners to choose between shared and exclusive lead formats with varying degrees of qualification depth. The platform supports API/interface/tracking integration for partners on request, enabling in-house routing of leads to internal sales teams. Interlead is self-financed and profitable, has grown headcount from a single founder in 2010 (formal incorporation 2013) to 100+ employees by 2024/2025, and reports continuous year-over-year growth for the last 10 years, with 2025 described as its most successful year on the back of 15+ new product launches.

The business model is a success-based, transaction-driven lead generation marketplace: the service is free for consumers, while partner companies pay per delivered lead or appointment, with no minimum commitment and monthly cancellation flexibility. Revenue is derived primarily from per-lead transaction fees, supplemented by platform access for partner qualification and routing workflows. Distribution is exclusively domestic (Germany/DACH), and customer acquisition is sales-led with a named Head of Sales, supported by inside sales and partner-direct contact channels.

Direct peers

• FINANZCHECK.de: German credit and finance comparison platform distributing consumer loan and finance leads to bank and insurer partners. Closely mirrors Interlead's financial-services vertical (Rightmart, etc.) using a B2B partner, success-based monetization.
• Heimhelden (Zalando subsidiary): German lead-generation platform for home services, renovation, and crafts. Closely comparable to Interlead's home-services/crafts vertical in target customer (homeowner), partner type (craftspeople), and performance-based lead delivery.
• smava: German online credit comparison platform routing consumer loan inquiries to bank partners. Comparable as a financial vertical lead-generation intermediary, monetizing through partner referral fees — same transaction-based revenue model as Interlead.
• Verivox: German comparison portal focused on energy, insurance, telecom, and financial products, brokering leads to partner providers. Directly comparable to Interlead in the energy and insurance verticals with a similar B2B partner monetization model.
• MyHammer: German online marketplace connecting homeowners with tradespeople and home service providers. Directly comparable to Interlead's home services/crafts vertical (Thermondo et al.), monetizing via lead or transaction fees from B2B partners.
• Aroundhome: Berlin-based lead generation platform connecting consumers with home and energy service providers (solar, heating, renovation). Closest German peer to Interlead — overlapping verticals (solar/energy, home services), B2B partner model, and performance-based lead delivery.
• CHECK24: Germany's largest consumer comparison portal, monetizing leads across insurance, energy, finance, real estate, and more. Same B2B2C comparison-and-lead-gen model as Interlead, with a far broader vertical and geographic footprint; serves as the dominant benchmark for Interlead's addressable model.

Broad incumbents

• Angi (Angi Inc.): Large US-based home services lead-generation platform connecting homeowners with pros. Comparable in business model (pay-per-lead B2B partner network in home services) but broader and more mature; serves as a strategic template for vertical depth.
• HomeAdvisor: US home services lead-gen marketplace (now part of Angi). Same homeowner-to-pro lead delivery model as Interlead's home services vertical, scaled across multiple US categories; useful comparability benchmark for category breadth.

Others

• Solarwatt: German residential solar/energy company. While not a direct lead-gen peer, it operates adjacent to Interlead's energy vertical and represents a typical B2B partner-side customer (similar to Enpal/Octopus Energy) that buys leads through comparison platforms.
