Funding fuels platform expansion to help financial institutions modernize operations for the AI era, scale with increasing client complexity

Avantos, an artificial intelligence (“AI”)-native operating system built to reimagine how financial institutions onboard and service clients, today announced it has completed a $25 million Series A funding round led by preeminent technology and software investment firm Bessemer Venture Partners ("Bessemer"). The round also attracted new strategic investors, including The Guardian Life Insurance Company of America® (“Guardian”), SEI® and Vanguard. This capital builds on the company’s $10 million seed round, which closed in September 2024 and was led by MIT-affiliated E14 Fund. The seed round also included M13, Mercer Advisors and Blue Collective.

Avantos intends to leverage the funding to support continued investment in its platform, including expanded AI agents as well as deeper integrations with custodians, CRMs, portfolio management tools, underwriting systems and policy administration platforms.

Avantos originated from a fundamental insight shaped by cofounders Bassam Chaptini and Rabih Ramadi’s extensive financial services experience. Many firms have clear strategic ambitions to manage and deepen client relationships, yet the fragmented platforms and functions they rely on today are not built to support that vision, hindering consistent execution across the client lifecycle.

Avantos addresses this misalignment through an AI-native system built on a knowledge graph that establishes context around client relationships—linking products, service teams, workflows and service expectations in one system. This shared system of context enables AI agents and human teams to operate from the same understanding of the client, allowing AI to reason across relationships, orchestrate work and execute tasks across systems, with the appropriate level of oversight. The result is a fundamentally consistent, personalized, compliant and scalable model for onboarding and servicing—driving deeper, more durable client relationships.

"Client service in financial services is drowning in point solutions and administrative burden. We believe that AI can change this paradigm, and that Avantos stands alone as a true end-to-end platform to deliver client services across wealth, insurance, retirement and banking. Its AI agents bring the required sophistication in advanced reasoning to handle the complex long-horizon tasks that define client management,” said Eric Kaplan, Vice President at Bessemer Venture Partners. “Bassam and Rabih bring rare empathy and insight from building enterprise software for these same institutions, and we’re already seeing that validated through partnerships with industry leaders.”

Avantos is backed by strategic investors and serves clients across the wealth management ecosystem, including asset managers, private banks, insurance carriers, broker dealers, independent RIAs and custodians.

“Avantos has transformed how our teams deliver an integrated standard of financial care across investments, planning, estate, tax and other services to meet the needs of our clients,” said Daniel Gourvitch, President of Mercer Advisors. “Avantos helps our teams stay connected and have deep, instant context on our client relationships. That connection enables us to deliver even more effectively on our fiduciary promise to the families that we serve.”

"AI is creating opportunities to transform how we support clients. Our partnership with Avantos reflects a promising step forward on that journey,” said Danielle Corey, Head of Client Service & Operations for Vanguard’s Advice and Wealth Management division. “Avantos’ capabilities can help us pair our teams’ insights and experience with a more comprehensive view of client needs, supporting our efforts to deliver an increasingly seamless and personalized experience.”

“Guardian’s investment in Avantos underscores our confidence in the transformative potential of this technology and reinforces our commitment to leveraging AI to modernize our platforms and enhance our wealth management capabilities,” said Mike Perry, Head of Client Solutions and Wealth Management at Guardian. “By reducing friction in the client experience and improving the productivity of our advisors, we will drive deeper relationships that help clients realize their individual financial plans and goals.”

“Avantos will be a catalyst for enhancing how we serve our clients by delivering a more integrated, end-to-end advisor experience,” said Jeff Benfield, Chief Product Officer at SEI. “By integrating AI-driven onboarding processes, real-time client insights and streamlined servicing tools across our asset management, operations and financial technology solutions, we will be able to create a more seamless, connected experience that helps further support the scale, flexibility and long-term needs of our clients.”
