Executive Summary
SellRaze is a mobile-first AI tool that reduces the friction of cross-listing secondhand goods. By automating listing creation and inventory management, it aims to capture a share of the growing creator economy for individuals and small businesses [Tech Square ATL, April 2025]. The founding story is rooted in personal frustration, with co-founders Jeff Mao and Tyler Ma developing the concept from their own experiences reselling sneakers while undergraduate students at Georgia Tech [Product Hunt].
The core product differentiates by focusing on speed, claiming to generate a listing from a photo in under a minute, and by managing the post-sale workflow across eBay, Facebook Marketplace, and Poshmark [Y Combinator]. The team's primary commercial validation comes from winning Georgia Tech's 2023 InVenture Prize and acceptance into the Y Combinator and CREATE-X accelerator programs [Georgia Tech News Center, March 2023].
Financing includes a disclosed pre-seed round of $560,000 led by angel investor Christopher Klaus and Fusen World, supporting a freemium SaaS model with paid tiers starting at $29.99 per month [SellRaze blog]. Key watchpoints include the conversion of its claimed 200,000-user base into sustainable paid revenue, execution of planned expansion into AI-driven buyer messaging and consignment services, and its ability to carve out defensible territory against established cross-listing competitors.

How the Company Got Here
SellRaze began as a student project by two roommates at the Georgia Institute of Technology. Co-founders Jeff Mao and Tyler Ma, both second-year computer science students at the time, won the university's 2023 InVenture Prize and its accompanying $20,000 award [Georgia Tech News Center, March 2023]. That victory granted them automatic acceptance into Georgia Tech's CREATE-X Startup Launch program, where they later secured first place at the program's I2P showcase [Hypepotamus, 2023]. The company was formally founded later that year and is headquartered in Atlanta, Georgia [Y Combinator].
A key early milestone was the company's admission to Y Combinator. In 2025, SellRaze announced a $560,000 pre-seed round led by Christopher Klaus and Fusen World [SellRaze blog].
Data Accuracy: YELLOW -- Founding narrative and prize details are corroborated by a university news outlet and a regional tech blog. The pre-seed funding announcement originates from the company's own blog, and Y Combinator participation is listed on its directory page.
Product and Technology
SellRaze's product is a mobile application designed to automate the most time-consuming parts of online reselling. The core workflow begins with a user taking a photo of an item, scanning a barcode, or entering text, after which the app's AI generates a complete listing in under a minute [Tech Square ATL, April 2025]. The system auto-fills product details, suggests pricing, and optimizes photos, then cross-posts the listing to multiple marketplaces including eBay, Facebook Marketplace, and Poshmark [Y Combinator]. Beyond listing creation, the app provides a suite of seller tools to manage inventory, track orders, handle buyer messages, and arrange free local pickups [Y Combinator]. The company also operates its own marketplace, integrated into the app, allowing for direct sales [Y Combinator].
The business model is a freemium SaaS, with tiers ranging from a free plan to a Plus plan at $29.99 per month and a Pro plan at $59.99 per month [Y Combinator]. Publicly announced expansions include AI-powered buyer messaging and consignment integrations with thrift stores [Tech Square ATL, April 2025].

Where the Demand Sits
The market for tools that simplify secondhand selling is expanding, driven by a shift in consumer behavior toward resale as both a side income and a sustainable practice.
ThredUp's 2024 Resale Report estimates the total U.S. secondhand apparel market reached $43 billion in 2023 and is projected to grow to $73 billion by 2028 [ThredUp, 2024]. Mercari reported 20 million active buyers and sellers on its U.S. platform in 2023 [Mercari, 2023]. SellRaze claims its process is 90% faster, reducing listing time to under one minute [Tech Square ATL, April 2025].
| Metric | Value |
|---|---|
| U.S. Secondhand Apparel Market 2023 | $43B |
| Projected U.S. Secondhand Apparel Market 2028 | $73B |
Data Accuracy: YELLOW -- Market sizing relies on an analogous report from a major industry participant (ThredUp) and a platform's self-reported user base.
Competitive Landscape
| Company | Positioning | Stage / Funding | Notable Differentiator | Source |
|---|---|---|---|---|
| SellRaze | Mobile-first AI app for casual sellers; cross-lists to eBay, FB, Poshmark, plus own marketplace. | Seed (~$1.06M) | Free tier, integrated marketplace for direct sales/pickups, AI photo-to-listing under 1 minute. | [Y Combinator] |
| List Perfectly | Established web platform for professional resellers; cross-lists to 10+ marketplaces. | Bootstrapped (est.) | Extensive marketplace integrations, bulk listing tools, desktop-centric workflow for high-volume sellers. | [Company website] |
| Vendoo | Web-based cross-listing and inventory management for resellers. | Seed ($2.2M) | Focus on inventory syncing and analytics, browser extension for sourcing. | [Crunchbase] |
| Foxtail.ai | AI tool for generating product listings from photos. | Early-stage (est.) | Specializes in AI-generated descriptions and titles, less focus on multi-channel posting management. | [Company website] |
The competitive map splits into three segments. At the professional end, tools like List Perfectly and Vendoo cater to high-volume sellers who list dozens of items daily from a desktop. A newer challenger segment includes AI-native point solutions like Foxtail.ai, which focus on automating creative copy. SellRaze targets the broadest, most casual segment: the individual cleaning out a closet. Its primary substitute is the manual process of listing directly on eBay or Facebook Marketplace, a time-consuming method the company claims to improve by 90% [Tech Square ATL, April 2025].
SellRaze's current edge is its integrated, mobile-centric product experience and its free tier. Durability will depend on whether the company can convert free users to paid tiers at scale and use the aggregated listing data to improve its pricing and recommendation algorithms faster than competitors.
The company is most exposed on two fronts. First, it lacks the deep marketplace integrations and inventory management sophistication of a Vendoo or List Perfectly. Second, it does not own a demand channel. While it has launched its own marketplace, this is a nascent effort with limited liquidity compared to the massive built-in audiences of eBay or Facebook Marketplace.
The most plausible 18-month scenario hinges on user conversion and capital. If SellRaze can effectively monetize its reported 200,000-user base [Y Combinator] and deploy its new funding to build superior AI messaging tools, it could become the default onboarding tool for new resellers, pressuring point-solution challengers like Foxtail.ai. Conversely, if monetization lags and incumbents like Vendoo introduce a competitive mobile AI feature, SellRaze could be squeezed.

Opportunity
SellRaze's opportunity centers on automating the fragmented, manual workflows of the individual reseller. The company's core motion, generating a listing from a photo in under a minute, directly attacks the primary friction point for casual sellers [Tech Square ATL, April 2025]. Initial traction metrics include 200,000 users and over 500,000 items listed [Y Combinator].
| Scenario | What happens | Catalyst | Why it's plausible |
|---|---|---|---|
| Vertical Integration | The SellRaze marketplace and its free pickup service become the preferred channel for users. | Strategic partnerships with local thrift stores or consignment shops. | The company has already launched its own marketplace and offers free pickups [Y Combinator]. |
| Horizontal Expansion | SellRaze becomes an indispensable SaaS suite for micro-businesses. | The launch of a successful AI messaging feature. | The company's stated roadmap includes expanding to "AI buyer messaging" [Tech Square ATL, April 2025]. |
Data Accuracy: YELLOW -- Growth scenarios and market context are based on company-stated roadmaps and general industry reports.
