ExchangiFi announced a strategic investment from Prosperity Venture Partners, the family office of investor and wealth management entrepreneur Tommy Mayes. As part of the investment, Mayes will join ExchangiFi’s board of directors.
ExchangiFi is an independent platform for Section 351 ETF exchanges. The company connects wealth advisors with ETF sponsors to seed funds without triggering immediate capital gains taxes.
Under Section 351 of the Internal Revenue Code, investors can contribute securities to an ETF in exchange for shares while preserving their original cost basis. This structure can help advisors transition clients out of tax-inefficient separately managed accounts and low-basis positions into liquid, transparent, and tax-efficient ETFs.
Mayes is the founder of Prosperity Venture Partners, a single-family office investment firm with investments across registered investment advisors, wealth and asset management firms, franchise businesses, and real estate. He also serves as a Family Office Chair for TIGER 21.
Mayes previously served as a general partner and board member at Blueprint Investment Partners, where he helped grow the asset manager and financial services platform from $75 million to more than $3.5 billion in assets. He also serves on the board of Investors Preferred, a private placement life insurance carrier.
Since launching in September 2025, ExchangiFi has attracted more than 40,000 visitors and built an email list of more than 3,000 registered investment advisors. The platform currently lists 11 open 351 exchange ETFs and has a pipeline of more than 30 syndicated 351 exchange launches in 2026.
ETFs launched in connection with the platform have collectively raised more than $1.85 billion in seed assets, though not all of that amount was raised through ExchangiFi. The company’s leadership team includes entrepreneurs and operators with experience across asset management, fintech, and ETF strategy.
ExchangiFi provides software that helps participants optimize portfolios, manage documentation, track capital commitments, and coordinate fund seeding. The company said its platform is designed to make Section 351 ETF exchanges easier for advisors, issuers, and clients to navigate.
KEY QUOTES:
“Tommy has spent his career advising families and the advisors who serve them, and he deeply understands the wealth and asset management businesses and the tax challenges ExchangiFi is built to solve. His experience as a board member and advisor will be invaluable as we scale the platform.”
Matthew Bucklin, Founder and CEO of ExchangiFi
“My work in the family office and wealth management space has convinced me that the new frontier for wealth management planning is income tax-focused, and I believe that Section 351 exchanges will be one of the most important tax and portfolio-management tools of the next decade. I see ExchangiFi as the independent hub for everything related to 351 exchanges, bringing advisors, issuers, and clients together while providing the infrastructure to support workflows and ensure compliance.”
Tommy Mayes, Founder of Prosperity Venture Partners
