A “successful” card payment can still leave merchants waiting days to actually access their money, paying layers of fees along the way, and carrying fraud risk that never truly goes away. That gap between authorization and settlement is where cash flow gets squeezed, reconciliation gets messy, and margins get quietly taxed, especially as more commerce shifts to e-commerce and other card-not-present channels.
We sit down with Marshall Greenwald, Founder and CEO of IoniaPay, to talk about changing the infrastructure behind merchant payments. Marshall walks us through how IoniaPay moves funds from a consumer’s card to a merchant’s bank account in real time, why that matters more than ever, and how collapsing a fragmented chain of 6 to 10 parties can reduce cost and complexity. He also explains the fraud angle: instead of relying on tools that “guess,” merchants want stronger certainty that a transaction is truly authorized by the cardholder.
We also get practical about where this fits best right now. Marshall shares why iGaming, travel, and healthcare see outsized value, how instant settlement can unlock meaningful working capital that would otherwise sit in float, and how the company goes to market through a mix of direct enterprise relationships and a broad reseller network. From there, we zoom out to the future of payments: multi-channel commerce, orchestration, interoperability challenges across a massive US ecosystem, and the broader shift from top-layer UX innovation to foundational payment infrastructure.
If you care about real-time payments, merchant cash flow, fraud prevention, and what “modern rails” should actually look like for everyday commerce, this conversation will give you a few sharp questions to bring back to your team.
