CarOnSale

CarOnSale is a Berlin-based technology company building what it describes as the AI-powered operating system for B2B used-car trading in Europe. The platform connects licensed dealers, professional buyers, OEMs, dealer groups and remarketers in a single system that spans AI-powered valuation, digital auctions, logistics and final handover. Its stated proposition is simple — one platform, one profit engine — replacing fragmented processes, opaque pricing and slow logistics with a connected layer built exclusively for professional used-car trading.

The core of the offering is a digital auction marketplace where vehicles sourced directly from dealer groups, OEMs and fleets are listed for verified commercial buyers. CarOnSale reports that roughly 130,000 vehicles are auctioned on the platform each year across more than 20 European markets, and that around 85% of the inventory it lists is not available anywhere else. Buyers gain access to thousands of vehicles with new auctions daily, smart search filters and the ability to bid live, set a bid agent or use Buy Now.

Condition transparency is central to the model. Listings include detailed condition reports under the COSCheck label, based on an inspection programme covering more than 110 inspection points. Sellers can book a vehicle inspection through CarOnSale or list directly with an external appraisal, and can request market price and guaranteed price information for trade-ins. Payments run through COSPay, and buyers can follow transport status live through to delivery, while sellers track sales, invoices and after-sales processes via a dashboard.

The company operates a mobile app for iOS and Android that gives both buyers and sellers access to live auctions, invoices, negotiation status and payment in one place. CarOnSale states that users pay only on a successful transaction — no subscriptions and no upfront costs — with every fee visible in the app. The platform is positioned as a free tool for registered dealers, with sign-up through the company’s website.

CarOnSale was founded in 2018 and has grown to a team of roughly 201 to 500 employees, according to its LinkedIn company page. Its origins trace to founder Tom Krüger’s observation that B2B car sales remained almost entirely manual and local while other parts of automotive retail had been radically digitalised. The company has since expanded from a German startup into a pan-European business, with offices in Berlin (its headquarters and largest office), Munich and Hamburg — the latter home to AlphaOnline, the used-car management software business — alongside field teams of vehicle inspectors and sales staff working on the road.

In 2025 the company introduced a new brand identity, presenting itself publicly as more than a marketplace: an AI-driven system for European B2B used-car trading.

CarOnSale describes its culture through six documented values: boldness, bias for action, data driven, ownership, one team and customer-centricity. The company says it works with a hands-on approach, an entrepreneurial spirit and a “ONE Team” mindset, and that its employees come from a wide range of countries. Its published benefits include a compensation package with a stock option programme, a mobility package with a subsidised job bike or Deutschlandticket (and a company car for sales employees), health and wellbeing memberships, employer-sponsored retirement contributions, regular company and team events including an annual summer event and COS Talks, and employee shopping discounts.

The company’s stated mission is to digitalise and transform the automotive retail industry, giving every car the right buyer at the right price at the right time. It presents itself as building infrastructure that an entire industry depends on, and invites people who want to shape the future of automotive wholesale to join its team.
