Bassam Chaptini, co-founder and co-CEO of Avantos, is helping redefine how artificial intelligence is deployed across financial services. Recognizing that AI is only as effective as the data and context behind it, Chaptini and co-founder Rabih Ramadi built Avantos as an AI-native operating system centered on a knowledge graph that unifies client data, products, workflows and service teams into a single system of context. This architecture enables AI agents to operate with the context, governance and oversight required for regulated, client-facing environments.. After more than two years in stealth, that approach was validated in February 2026 when Avantos closed a $25 million Series A led by Bessemer Venture Partners, bringing total funding to $35 million. Vanguard, Guardian Life, SEI and Mercer Advisors all joined as strategic investors and are simultaneously deploying the platform across their own operations
