Marshall Greenwald
Founder
What if the payments industry shifted from waiting days for funds to having cash in your hands within minutes?
Marshall Greenwald has spent over two decades in payments watching merchants struggle with slow settlements, excessive fraud, and broken infrastructure—and he decided that enough was enough. As the founder of IoniaPay, he’s building a payment system that dramatically reduces the friction in how money moves from consumer to business. Instant settlement, reduced fraud risk, and a vision to make payments as seamless and reliable as sending a text: that’s what he’s after.
His journey didn’t come from a tech startup dorm, but from deep inside the machinery of banking, credit card processing, and payments solutions, learning where the leaks are. Along the way, he’s learned what many overlook: that small delays, lack of transparency, and distrust cost more than just dollars—they cost relationships, confidence, and momentum.
This is a story about innovation grounded in merchant pain, about building something that doesn’t just scale—but transforms how people get paid. If you believe speed, fairness, and clarity are overdue in business, Marshall’s experience will shift what you expect from money moving in your world.
