Before co-founding SellRaze, the startup's CTO, Tyler Ma, did not know how to code. However, when fellow University of Georgia freshman Jeff Mao—CEO of SellRaze—presented Ma with an idea to streamline the tedious process of reselling shoes online, he decided to learn through the experience of creating a startup.

Flash forward to the fall of 2022. The pair transferred to Georgia Tech, where they would go on to win the InVenture Prize and receive support from the founder and CEO of Kaneva and Fusen, Christopher Klaus. Now, they work from the TSQ ATL Clubhouse and are innovating in the world of reselling, creating the fastest, all-in tool for selling secondhand online.

SellRaze lets users quickly and easily create and track listings across various reselling platforms. The process goes as follows: the seller takes a photo of the item they would like to post, and they will be shown similar listings across marketplaces. Then, based on the other listings, the app will generate the user's details, including a title, description, shipping size, and a suggested price. From there, the listing can be toggled on and off marketplaces like eBay, Facebook Marketplace, Poshmark, and more. However, purchases can also be made directly off the SellRaze app. The user will then be notified once there's a purchase request, and they can take the product off the other platforms.

Using SellRaze, creating and posting a listing for an item takes less than a minute, making the process 90% faster than leading marketplaces. The time-consuming nature of reselling is one of the biggest challenges for sellers. "For a lot of these people, it's their full-time job, and even if it's your side thing, it takes up a lot of time," said Ma. It was this very issue that inspired Mao and Ma to create SellRaze.

However, SellRaze's co-founders are not the only college students interested in reselling. Ma cited the popularity of secondhand shopping as one of the significant reasons for SellRraze's mission to make the process more accessible: "With the younger generation, thrifting has become more common and secondhand goods are increasingly popular."

According to ThreadUp's 2025 Resale Report on the online secondhand market, the global market for secondhand apparel is set to reach $367 billion by 2029, growing 2.7 times faster than the overall apparel market. This popularity is especially prevalent among younger consumers. In 2024, 68% of Gen Z and Millennial consumers shopped for secondhand apparel, and 39% resold it.

Despite the growing popularity of online secondhand shopping, in the same report, 30% of consumers stated that they feel overwhelmed by online thrifting. That's where SellRaze comes in. The app makes both buying and selling online personalized and time-efficient.

According to Ma, the team is working on raising more capital so they can focus on the next steps, such as "[expanding] businesses to consignment stores and thrift shops, merging the online and in-person sales aspects." The team also wants to create AI messages that respond to user purchase requests, again focusing on making the online selling process as easy as possible.

"Used cars are very common, and we want to make it so that buying used items is just as socially acceptable."
