About Antonio Bustamante
Antonio Bustamante is the co-founder and CEO of bem, an AI infrastructure company based in San Francisco. He was born in Spain and grew up in Madrid, Barcelona and Quito, and he studied computer science at Universidad Politécnica de Madrid.
His earlier career started in Europe, where he founded a health-tech software consultancy that Kyowa Kirin acquired. He also worked on industrial design and strategy projects for clients such as Paypal and Samsung. From 2014 to 2017 he was a founding team member, designer and engineer at Kite, an AI assistant for programmers that Affirm acquired. He then founded Silo in 2017 and led its engineering, product and design until early 2023. Silo is an operating system for the food supply chain.
He started bem in 2023 with Upal Saha, an engineering manager from Silo. In June 2024 bem announced a $3.7M seed round led by Uncork Capital, with participation from Kevin Mahaffey, Roar Ventures and angels including Garry Tan. On X he describes himself as a 4x founder.
Little of his angel activity is public. Crunchbase lists one investment and one portfolio company: Nuvo, in a Series A round. The date and amount are not shown on the public Crunchbase page. Crunchbase shows no lead investments and no exits. His Crunchbase bio invites founders building something interesting to meet for coffee.
No AI angel investments by Bustamante have been announced publicly. His AI experience is as an operator. He built Kite, an AI coding assistant, and now runs bem, which turns unstructured files such as PDFs, emails and scanned documents into structured data for software. He has said bem chose to be infrastructure rather than build AI agents.
He has not published a stated thesis, preferred stage, geography or check size, so none is given here. His own work points to interests in AI infrastructure, developer tools, and complex industries such as supply chain, logistics, healthcare, insurance and financial services. These are the sectors bem serves, and they are inferred from his operating background rather than from a statement about his investing. Founders can reach him through his public profiles.
