Ionia’s fix for payment delays & fraud

Marshall Greenwald on Around the Coin with Stephen Sargeant

When someone shows up to a video podcast wearing a shirt that says “I got 99 problems, but fraud ain’t one,” you know things are about to get interesting. That was exactly the scene on Around the Coin, where host Stephen Sargeant welcomed Ionia founder Marshall Greenwald for a deep dive into the real problems plaguing merchants today—like why some stores wait days to get paid and still get slammed by “friendly fraud” that’s not friendly at all.

Marshall has spent over two decades in the payments space. He’s seen it all: the old-school days of physical card imprinters (“knuckle busters”) to the explosion of digital payments that still rely on rails from yesteryear. Frustrated by how little had truly changed, he set out to invent a system that actually moves money in real time. Throw in 100% indemnification against fraud and you have the basis for Ionia.

A t-shirt that says it all

It’s not every day you see a founder proudly wearing a jokey-but-dead-serious mantra on a podcast. Marshall’s shirt underscored a big claim: by weaving identity checks into the payment flow, Ionia can block fraud from the start. They don’t pass chargebacks on to merchants—it’s Ionia’s liability if something slips through.

This approach means no rolling reserves, no piles of disputed transactions, and no “friendly fraud” fiascos that drain a merchant’s time, money, and patience. For small businesses, those savings alone can fund real growth. For enterprise-level brands, it keeps operating costs predictable and frees up cash that used to vanish into the black hole of settlement delays.

A name with an ancient legacy

People often wonder where “Ionia” comes from. Turns out it’s the name of a region in ancient Greece, smack in the middle of the Silk Road. Forced to deal with merchants arriving from all corners of the world, Ionian traders invented one of humanity’s first official currencies. Marshall loves that the region is largely forgotten, even though it shaped global commerce for millennia. Ionia’s coin-stamp tradition lives on in their logo and in the platform’s mission: to modernize trade without demanding a spotlight.

Marshall co-founded the company with his father, an attorney who brings the perfect counterbalance to Marshall’s sky-high ambitions. While Marshall dreams of real-time payment utopias, Dad asks tough questions about regulatory compliance and legal structure. It’s a creative tension that’s led to a solution with both visionary speed and bulletproof safeguards.

Chasing speed and killing fraud

Why does instant funding matter? Many merchants operate on razor-thin margins, and waiting days—or a holiday weekend—to get paid can wreck their cash flow. The retail giant that misses out on leveraging millions of dollars stuck in a “settlement float” might be annoyed, but the local restaurant that can’t cover payroll is in real trouble.

Ionia doesn’t just settle transactions instantly; it also shifts fraud risk away from merchants. The system confirms that the person making the purchase is who they say they are, matching the card, phone, and user identity. If something goes wrong, it’s on Ionia, not the business. There’s still a fallback to traditional rails for cards Ionia can’t process, but most transactions sail through and settle in seconds.

From tiktok to twitch: meeting gen z expectations

Stephen and Marshall also explored how Gen Z, with its instant streaming and “buy now” culture, is changing commerce. Apps like Whatnot or TikTok live-selling let consumers spot something cool, tap “Buy,” and move on—no messing with a clunky checkout. While that might be fun for shoppers, it’s a logistical nightmare for merchants depending on slow bank settlements and vulnerable card networks.

Ionia keeps up by collapsing all those middle steps. Consumers authenticate once, and merchants see the money right away. Combine that speed with lower fees, and it’s no surprise companies from bike shops to massive online retailers want in.

Two bites at the apple

Some merchants worry that adding even a slight step—like a text link for verification—might scare off customers. Ionia solves this by never fully declining a transaction. If a customer doesn’t respond, the payment automatically reroutes to the business’s existing setup. Businesses get “two bites at the apple,” one with Ionia and one with the traditional rail if needed.

Fraudsters, meanwhile, hate anything that demands real proof of identity. When criminals see an extra barrier, they move on to easier prey. That leaves the legitimate buyers who appreciate knowing they won’t get tangled up in stolen-card drama. As for the merchants, they’re off the hook for chargebacks. It’s basically a win-win, minus the con artists.

This was just a slice of what Stephen and Marshall chatted about. Whether you’re a curious consumer, a scrappy startup, or an enterprise merchant tired of getting dinged by fees and fraud, you’ll want to hear the full conversation. Marshall’s insights on banking partnerships, KYC protocols, and taming friendly fraud offer a blueprint for how digital payments can move into the modern age.
