History
Fermat, Inc. was established on 11 October 2013 in Japan. According to the company's own account, it began with e-commerce sales of overseas apparel products and a range of related system development. From that starting point it broadened the products and services it handles, moving into PC-related devices, the manufacturing and sale of cosmetics, and e-commerce agency services. Over time the company built out three principal business lines. The electronics business operates "fumo-shop" (ふもっふのおみせ), an authorized distributor of popular and emerging overseas gaming devices, which the company describes as acting as a "weapons merchant of eSports" and which it uses as a platform to expand into sponsorships and event planning. The IP collaboration business, "fumo collection" (ふもコレ), is fumo-shop's original IP collaboration brand, planning, producing, and selling original merchandise in collaboration with popular games, anime, and VTubers, with gaming devices at the center. The trading card business, "fumo TCG" (ふもっふトレカ), entered the trading card game market around Pokémon cards, handling card buying and selling, developing the original brand "FUMOTEX," and actively hosting events and tournaments for players. The company is headquartered in Kamimeguro, Meguro-ku, Tokyo, with stated capital of 8,000,000 yen and a fiscal year ending at the end of September. Its representative director and president is Tsutomu Matsumoto. In its recruitment messaging, Director and Vice President Wakiyama recalls that Fermat started from overseas apparel e-commerce and related system development and has since expanded into PC-related devices, cosmetics, and e-commerce agency work, and stresses a stance of not being satisfied with the status quo and of searching the world for good products. Takahashi of the electronics business department describes running the authorized overseas gaming device store fumo-shop as manager and merchandiser, handling everything from dealings with overseas manufacturers to purchasing and sales launch, and frames the team's ambition as becoming the "weapons merchant" and aiming for the championship of the eSports industry.
