Infobird is a Cayman Islands holding company listed on Nasdaq that operates through Pure Tech Global, a digital advertising and marketing services business in China acquired in late 2024. Pure Tech provides end-to-end digital marketing services to corporate clients, with a focus on the maternal and infant care sector. Services include social media marketing, SEO, content distribution, brand strategy, creative development, and PR. Pure Tech distributes campaigns across vertical maternal and infant channels — including Qinbaobao, BabyTree, and Mama Network — as well as cross-industry platforms like Douyin. Revenue is driven by the volume and scale of marketing campaigns managed for clients. Customer concentration is extreme: two clients in the maternal and infant sector account for over 90% of revenue, making Pure Tech function less like a diversified marketing agency and more like a dedicated provider to a very small number of clients. The business operates through a VIE structure, as Chinese regulations restrict direct foreign ownership of certain internet and technology businesses. Infobird controls Pinmu Century, the primary operating entity, through contractual arrangements, with earnings flowing up through the structure via service fees. Infobird sold its original SaaS-based AI customer engagement platform in 2023 for a nominal sum, and had no meaningful operations until acquiring 97% of Pure Tech across two transactions in late 2024.
