Mashup Ventures led a seed investment in Thermit, an AI commerce tech startup that operates the marketing content agent Creazy.
The investment amount was not disclosed.
Creazy analyzes a product’s features and generates the content online sellers need, including AI-built product detail pages, thumbnails, banners and short-form videos, in under three minutes. It is built on AI multi-agent managing technology, which Thermit says is the first in Korea to have a patent application filed. The company says this enables precise AI editing.
Detail pages made with Creazy are produced as code (HTML) that keeps the text intact. Existing AI design services typically output images, but with Creazy, search engines and AI can read the text inside the content directly. According to Thermit, this helps with search visibility and with adapting to AI shopping agent environments. Creazy was also trained on more than 50,000 pieces of commerce content whose sales performance has been verified, and is designed to produce content that leads to purchases.
Ten months after its official launch, Thermit had signed more than 15,000 customers through partnerships and word of mouth alone, and had reached monthly profitability.
CEO Jisung Kim previously led enterprise (B2B) AI software projects at a medical AI startup. He later founded a perfume brand and an AI multi-agent platform, gaining experience in both commerce operations and AI product development. Running the perfume brand, he found that producing marketing content took significant cost and time. He decided to start Thermit after concluding that AI could bring a productivity shift to online commerce as well.
Seungguk Lee, a partner at Mashup Ventures, said, “Thermit secured more than 15,000 customers through partnerships and word of mouth alone within 10 months of its official launch, and achieved monthly profitability.” He said the firm valued the startup’s quick access to sellers as the market moves toward an era of AI agents shopping on behalf of people. He also cited the founding team’s expertise in development, product and sales.
Kim said that when AI agents, rather than people, find, compare and decide on products to buy, how accurately AI understands a product will determine sales. “That is why Creazy creates content as code that AI can read from the start,” he said. He added that Thermit plans to use the investment to build commerce infrastructure that helps sellers’ products get chosen by both people and AI agents.
