Mashup Ventures, a firm that invests in startups at their earliest stages, announced on November 4 that it has put seed money into Thermit, a commerce technology company built around artificial intelligence.
Thermit makes software that generates the marketing material online sellers need, and structures that material so it can be understood not only by human shoppers but also by search engines and the AI agents that increasingly shop on consumers' behalf. The size of the investment was not disclosed.
What Thermit's Creazy Service Does
The company's main product, Creazy, examines the characteristics of a product and then produces the assets a seller typically needs to list it online. That includes detailed product pages, thumbnail images, promotional banners and short-form video.
According to the company, the full set of content can be generated in about three minutes. For small merchants who would otherwise hire designers or spend hours on listings themselves, that kind of speed addresses a common bottleneck in e-commerce.
Multiple AI Agents Splitting the Work
Rather than relying on a single model, Creazy uses a multi-agent approach. Separate AI components take on distinct roles, such as planning the content, analyzing the product and producing the final assets.
Thermit has filed patent applications covering this technology. To steer the output toward listings that convert, the system was trained on more than 50,000 pieces of commerce content that had already demonstrated strong sales results.
Built to Be Read by Machines as Well as People
A key design choice is that Creazy outputs product detail pages as HTML code instead of flat images. Many online storefronts rely on image-heavy listings, which can make the underlying text difficult for software to parse.
By keeping the text intact in code, Thermit's pages can be read directly by search engines and by AI shopping agents, the services that search for, compare and recommend products for consumers. As these tools gain traction, how clearly a product is described to them may affect whether it is surfaced at all.
Early Traction Without Paid Marketing
Mashup Ventures said Thermit signed up more than 15,000 business clients within ten months of its official launch. That growth reportedly came entirely through partnerships and referrals rather than advertising.
The startup has also reached profitability on a monthly basis, a notable milestone for a company still at the seed stage.
A Founder Who Felt the Problem Firsthand
CEO Kim Jiseong previously developed enterprise AI software at a medical AI startup before going on to found a perfume brand and an AI multi-agent platform. Running the perfume business showed him how costly and time-consuming it was to produce marketing content, which led him to start Thermit.
Kim argues that as AI agents begin to discover, compare and buy products for people, "how accurately AI understands a product will determine sales." He said the new funding will go toward building commerce infrastructure that helps sellers' products get chosen by both human shoppers and AI agents, according to a report by Asia Business Daily (Asia Kyungjae).
Lee Seungguk, a partner at Mashup Ventures, said the firm was drawn to the team's ability to quickly build relationships with sellers as shopping shifts toward AI agents, along with its strengths across development, product and sales.
Why the Deal Matters for Online Sellers and Startups
The investment reflects a growing bet that e-commerce visibility will depend less on eye-catching images alone and more on whether product information is legible to software. Tools that serve both audiences could become a standard part of the seller's toolkit.
For founders, Thermit's story also highlights the value of solving a pain point experienced directly, and of reaching profitability early through organic growth before raising outside capital.
