What CarDoor does

CarDoor Inc. is a Toronto-based, privately held online car-selling platform founded in 2021 by CEO Matthew McKenzie and operating in Canada. The company targets individual Canadian vehicle owners who want to sell a car without visiting a dealership or transacting with strangers, and it runs a self-serve flow that takes the seller from vehicle profiling to guaranteed offer, paperwork, pickup or drop-off, and same-day payment via certified cheque or EFT. The service is currently live in Ontario, with an additional physical drop-off location in Etobicoke (52 Titan Dr), and the company is expanding across Canada.

The core product is MarketCheck™, a proprietary dealer-competition mechanism. A seller submits vehicle details and photos; the platform packages these into a profile and presents them to hundreds of verified dealers in real time, who compete to buy the vehicle. The result is a single guaranteed offer within 24 hours, replacing the single-offer trade-in or labor-intensive private-sale workflows that CarDoor explicitly positions against. The platform is delivered through cardoor.ca and a mobile app, with image and structured data inputs feeding the dealer profile workflow.

The business model is a two-sided marketplace monetized on the dealer side via transaction fees. Sellers pay nothing — no listing fees, commissions, or deductions — and the headline offer is the seller’s payout (less any outstanding loan or lease balance, which CarDoor pays off directly). Revenue is therefore a function of dealer take rate and per-vehicle transaction volume, supported by a marketing mix spanning earned media (Globe and Mail, Toronto Star, Yahoo News, BusinessWire), paid social and display, organic social, email, and a referral incentive ($50 Uber voucher for drop-off). The company has raised $3 million CAD in seed funding led by Framework Venture Partners (September 2021) to fund national expansion and planned service additions including trade-ins, financing, insurance, and at-home test drives.

Emerging players

• Shift: Online used-car platform offering home test drives and instant offers, with a marketplace-style seller experience comparable to CarDoor's flow.
• Instamotor: Earlier-stage online peer-to-peer and dealer car-selling platform that competed in the same 'no-stranger private sale' lane as CarDoor (operations have been limited, included as historical comparable).

Broad incumbents

• Vroom: US online used-car seller with instant offers and home delivery. Provides a cautionary large-scale analog for unit economics and capital intensity in the category.
• Carvana: US online used-car platform with home delivery and instant offers. A large-scale analog demonstrating the model, though US-focused and with a vertically integrated inventory model.
• Cars.com: Large US online automotive marketplace that has added instant-offer / dealer-competition features, increasingly overlapping with CarDoor's value proposition.
• CarMax: The largest US used-car retailer with an instant-offer / appraisal online channel. Operates broadly with physical stores but overlaps with CarDoor on the seller-side online instant-offer flow.
• Kijiji Autos: Major Canadian classifieds platform with a large vehicles vertical. Competes with CarDoor for private-party sellers and used-vehicle demand in Canada.
• AutoTrader.ca: Canada's leading automotive marketplace connecting buyers and sellers. While not an instant-offer model, it competes for seller attention and dealer advertising spend.

Direct peers

• Clutch: Canadian online used-car retailer offering buying, selling, financing, and at-home delivery — the closest direct competitor to CarDoor in the Canadian online car-selling market.
• ACV Auctions: Operates a dealer-to-dealer online auction platform, conceptually the closest analog to MarketCheck™'s competitive-bidding model applied to used-vehicle inventory.
