The 30-Year-Old Startup Selling You a Fender Before the Body Shop Can

In the mid-1990s, if you cracked a headlight or dented a fender, your options were narrow: the dealer's parts counter, a salvage yard, or a body shop that quietly marked the piece up on its way to your invoice. The part existed. It was just stuck - on a local shelf, in a regional warehouse, behind a phone call and a markup. Two entrepreneurs in Southern California, Sol Khazani and Mehran Nia, looked at that friction and decided the fix was a catalog you could reach from anywhere. In 1995 they founded U.S. Auto Parts Network. Thirty years later, that company is CarParts.com, it does more than half a billion dollars a year, and it is still arguing that the driver - not the middleman - should get the good price.

The pitch has stayed remarkably consistent across three decades and one rebrand: a broad, searchable catalog of aftermarket parts, priced below the dealer, shipped fast, sold direct. What has changed is everything underneath it - the warehouses, the private-label brands, the software, and, most recently, the ownership structure that keeps the whole thing independent.

01 / What it doesA parts store that thinks like a search engine

CarParts.com sells aftermarket automotive parts and accessories - the replacement, collision, and maintenance pieces a car needs over its life. Think mirrors, radiators, brake pads, headlights, bumpers, control arms. The catalog runs past a million SKUs, and the hard problem is not carrying them; it is matching the exact right part to the exact right car. A 2014 Camry mirror is not a 2015 Camry mirror. Get that wrong and you own a return, a refund, and a frustrated driver.

That fitment problem is why the company spends so heavily on software. In 2024 it rebuilt its search and recommendation engine around machine learning, aiming for more relevant results and fewer wrong-part returns. Its technology stack pairs old-school fitment discipline with modern tooling - cloud infrastructure, a mobile-first storefront, and AI systems that include large language models - to answer a deceptively simple question: does this fit your car?

02 / Who buysThe driver who would rather do it himself

The core customer is the DIY driver: cost-conscious, comfortable with a socket wrench, and unwilling to pay dealer prices for a part they can install in the driveway. Around that core sits the "do-it-for-me" shopper who buys the part and hands it to a mechanic, and, increasingly, professional installers and repair shops served through a growing wholesale channel. The company has been widening that base on purpose, adding last-mile transport and sales support to court business buyers alongside consumers.

The audience is showing up where the company wants it to. The mobile app has passed 1.3 million cumulative downloads and now drives about 13% of revenue, up from under 8% a year earlier - a shift management frames as changing its "paid versus nonpaid traffic mix," which is a polite way of saying it would like to stop renting so many customers from search-ad auctions.

03 / The problem it solvesCheaper than the dealer, faster than the wait

Two frustrations define auto repair: it costs too much and it takes too long. CarParts.com attacks both. On price, its private-label parts can land up to 50% below OEM in many categories, because the company controls the label and the supply rather than reselling a marked-up brand. On speed, it runs a national distribution network - with hubs positioned to reach roughly 95% of the United States within two days - so the part shows up before the weekend project stalls.

The private-label strategy is also the margin strategy. House brands carry gross margins estimated at 10 to 15 percentage points higher than comparable third-party SKUs. That is why owning the brand matters more than any single product: it is the difference between selling a fender and keeping the profit on it.

04 / Products & servicesMore than a checkout button

The storefront - web and app - is the front door, but the business has grown a few more rooms. There is CARP+, a paid membership introduced in 2024 that bundles discounts and perks and, more strategically, tries to turn a twice-a-year buyer into an annual subscriber. There is the wholesale channel for professional installers. And there is the portfolio of owned brands, headlined by JC Whitney, the mail-order auto-parts name with more than a century of history that the company acquired in 2010 and has spent recent years reviving.

In March 2026 the company and its partner A-Premium announced the biggest chapter yet in that revival: a 30,000-SKU JC Whitney branded product line, repositioning the vintage catalog name as a modern, digitally driven line carried on the national delivery network. It is nostalgia wrapped in fulfillment - a brand people already trust, riding infrastructure they never see.

05 / Business modelOwn the label, rent the warehouse

At its simplest, CarParts.com is a direct-to-consumer and business-to-business seller that makes more per part because it owns most of the brands it sells. Revenue comes from parts across web and mobile, a rising wholesale line, the CARP+ membership, and a newer, marketplace-style arrangement with A-Premium that expands the catalog without the company holding all the inventory.

The fiscal 2025 numbers show a company mid-reset. Net sales were $547.5 million, down 7% from the prior year, with a net loss of $50.4 million and gross margin of 32.8%. Management is candid that this is a deliberate trade - upgrading the customer base, cutting fixed costs, and rebuilding unit economics rather than chasing a demand rebound it cannot control.

06 / What's differentNot AutoZone, not RockAuto

The aftermarket is crowded. Brick-and-mortar giants like AutoZone, O'Reilly and Advance Auto Parts own the corner-store convenience play. Online, RockAuto competes on breadth and bare-bones pricing, while Amazon and eBay Motors compete on habit. CarParts.com's wedge is the combination it controls end to end: its own brands, its own fitment data, its own two-day network, and a customer relationship it is trying to deepen with membership and a mobile app rather than winning one search-ad click at a time.

House brands are about three-quarters of sales - which is really the whole margin story in a single number.On the private-label strategy

07 / Expertise & the moneyA $35.7M vote to stay independent

In September 2025, after exploring a possible sale, the company chose a different path: a $35.7 million strategic investment from three global players - ZongTeng Group, A-Premium, and CDH Investments - and it called off the sale. The logic is as much operational as financial. A-Premium brings more than 150,000 additional parts to the catalog. ZongTeng brings a global logistics footprint of over 24 million square feet across 50-plus US facilities, letting CarParts.com extend delivery reach without pouring capital into new warehouses of its own.

That expertise - three decades of fitment data, a private-label supply chain, and now a global logistics partner - is the moat. The A-Premium commercial partnership alone runs at roughly $35 million in annualized revenue, with a near-term target of $50 million and ambitions beyond $100 million.

08 / Where it fitsThe DIY corner of a giant, offline market

The automotive aftermarket is enormous, deeply fragmented, and still largely offline - which is precisely the opening. CarParts.com occupies the digital DIY-and-value corner of it, arguing that the driver who once called three counters for a price should get the same two-day, mobile-first, AI-searched experience the rest of retail trained them to expect. It has survived long enough to reach its fourth act - from catalog to IPO to rebrand to AI-and-logistics reboot - which in e-commerce is its own kind of achievement.
