Bidbus raises $15 million to let dealers bid on used cars

Bidbus raised $15 million in a Series A round led by Ibex Investors, giving fresh capital to a used-car marketplace built around live dealer competition. The startup says its pitch is simple: instead of taking one trade-in offer, a seller can list a car and let more than 1,000 verified franchise and independent dealers bid during a two-hour auction.

That structure is the heart of Bidbus’s consumer-power argument in a market where trade-in pricing is often opaque. Bidbus says sellers do not have to accept a low bid, and if offers fail to reach the minimum price the owner sets, the car stays put with no obligation and no fees. The company also says 80% of customers get more money with Bidbus, a claim that will matter most to shoppers trying to compare convenience against bargaining leverage.

The round extends a business that Bidbus says has already been used by more than 189,000 sellers. The company operates in California and Texas and says it does not buy cars directly, instead connecting consumers with dealers looking for inventory sourced straight from drivers. Bidbus was founded in 2022 by former auto dealers, brokers and wholesalers, a background that helps explain why the platform is built less like a classifieds site and more like a fast-moving wholesale lane.

Ibex Investors, which says it has more than $1 billion in assets under management and invests through an early-stage mobility-focused strategy, is backing that approach. Bidbus had previously raised $3.3 million in seed funding in July 2025, led by Mucker Capital. The new financing suggests investors see room to scale a model that tries to turn private-party selling into a real-time auction rather than a one-off negotiation.

Bidbus’s public results pages show bidding activity across a wide spread of vehicles, from Toyota Camrys, Nissan Rogue Sports and Scion xBs to Audi S3s, Audi Q7s, Mercedes-Benz C-Classes, Buick Encore GXs and Ford E350 vans. That mix shows the platform is not chasing only late-model sedans; it is also trying to funnel both mainstream and less common used cars into a dealer bidding pool that can move quickly and, in Bidbus’s view, pay better than a single offer across the desk.
