733Park, a boutique mergers and acquisitions advisory firm specializing in payments, fintech, and SaaS, announced that it advised Alipse Payments on its acquisition of ReliantPay, Inc., a Missouri-based independent sales organization (ISO) and payment processing business. Terms of the transaction were not disclosed.

733Park, the boutique M&A advisor payments and AI founders call first, guided Alipse Payments' acquisition of ReliantPay, Inc., a Missouri ISO and merchant processing portfolio. 25+ years, 200+ deals, $10B+ closed across payments, fintech, AI, and SaaS.

733Park represented Alipse on the buy-side, sourcing and vetting the opportunity and running the process through to a signed and funded close in June 2026. The acquisition brings ReliantPay's merchant processing portfolio, residual revenue streams, and related assets under Alipse.

“Alipse came to us knowing exactly the kind of merchant portfolio they wanted. Our job was to find it, pressure-test it, and close it on the right terms,” said Lane Gordon, CEO and Managing Director of 733Park. “That is what 25 years of payments M&A buys you. Whether it is an ISO, a merchant processing portfolio, or a payments software company, we know the buyers, we know the sellers, and 80 percent of the deals we take to market get done.”

The transaction underscores 733Park's buy-side advisory practice, where the firm helps acquirers identify, evaluate, and close acquisitions of payment processors, ISOs, and merchant processing portfolios across the payments and fintech space. 733Park works across sell-side and buy-side mandates for companies with enterprise values from $2 million to $350 million.
