What Partcatalog.com does

PartCatalog.com operates a direct-to-consumer e-commerce platform for automotive replacement parts, headquartered in Austin, Texas. The platform offers more than 750,000 parts from 200+ brands — including ACDelco, Bosch, Dorman, Gates, Moog, Delphi, SKF, Denso, and Motorcraft — across 80+ product categories covering brakes and rotors, engine components, suspension and steering, electrical and sensors, A/C and cooling, fuel systems, gaskets and seals, and drivetrain and CV components. Its core technology is a vehicle fitment verification system that maps individual SKUs to specific year/make/model configurations, supported by a free VIN decoder tool that automatically identifies a customer's vehicle and surfaces compatible parts.

The company serves two defined customer segments: individual vehicle owners and DIY mechanics performing their own repairs and maintenance (primary), and professional mechanics and automotive repair facilities seeking verified-fitment parts to reduce comeback repairs (secondary). The revenue model is transaction-based e-commerce — unit-priced hardware sales with individual part pricing ranging from approximately $10 for basic filters and sensors to over $3,500 for turbochargers and full assemblies. The platform offers free shipping to the continental United States, a 60-day money-back guarantee, and free return shipping for incorrect fitments. Distribution is exclusively through the owned storefront; there is no mobile app, no third-party marketplace integration, and no international shipping.

PartCatalog.com was founded in 2013 and operates with 1-10 employees under founder/owner Alan Marek. The company is privately held with no disclosed funding, parent company, partnerships, acquisitions, or institutional ownership. Go-to-market is product-led growth: customers self-serve via vehicle selection or VIN entry, with SEO-optimized vehicle-specific category pages driving top-of-funnel discovery and email marketing supporting mid-funnel engagement.
