Live from Shoptalk: How Signifyd Is Redefining E-Commerce Fraud Protection Beyond the Checkout

By Isaac Morey

Fraud doesn’t sleep, and neither does the challenge of keeping good customers happy while stopping bad actors in their tracks. In this live episode of Talk Commerce, recorded on the floor of Shoptalk in Las Vegas, host Isaac Morey sat down with Nicole Jass from Signifyd for a candid, fast-moving conversation about what it really takes to protect an e-commerce business today — without driving away the customers you’ve worked hard to earn.

From machine learning and consortium data models to agentic commerce and instant refunds, Nicole covers the full spectrum of what modern fraud protection looks like — and why it’s about so much more than just stopping a bad transaction.

Key Takeaways

  • Fraud protection should grow revenue, not just cut losses. Signifyd helped Lenovo increase top-line sales by 4–5% by reducing false declines alongside fraud.
  • The consortium model is a force multiplier. Sharing fraud signals across thousands of merchants means that stopping one bad actor protects everyone on the network simultaneously.
  • Not all bots are bad anymore. Agentic commerce is changing how merchants need to think about automated traffic, and Signifyd is already preparing for that shift.
  • Returns are the next fraud frontier. Instant refunds are a loyalty-building tool — but only when merchants can tell the difference between a genuine return and someone shipping a box of rocks.
  • Scaling fraud teams with people alone won’t work. As businesses grow, “Katie reviewing transactions” isn’t a sustainable strategy. Machine learning fills the gap efficiently.
  • The customer experience IS the product. Every decline, every friction point, every delayed refund is a moment of truth that either builds or breaks brand loyalty.

About Nicole Jass

Nicole Jass currently serves as Head of Strategy and Chief of Staff at Signifyd, bringing a career built at the intersection of payments, product development, and data-driven commerce. An entrepreneur and founder turned product executive, Nicole has a deep background in payments and data-driven enterprises, having previously held key roles at Prove, Worldpay, and FIS.

Episode Summary

Isaac opens the conversation by asking Nicole to explain what Signifyd actually does. Her answer is straightforward: they stop bad actors from buying things at merchants’ stores. But here’s the catch — stopping fraud too aggressively can block the good guys just as easily. “It could be you when you get declined when you’re trying to check out,” she points out, framing the central tension that Signifyd’s entire platform is built to resolve.

Nicole walks through what she calls three layers of “magic” that power the platform. First, there’s the consortium model — Signifyd works with major brands including Lenovo, Walmart, Vuori, and Aloe, pooling fraud signals so that a bad actor blocked at one merchant is flagged across the entire network. Second, there’s data collection. The platform captures device information, location data, how long it took someone to build a cart, and whether an email address has ever appeared with a particular payment credential. Third — and this is where most platforms fall short — is actually doing something useful with all that data. Signifyd’s machine learning models process every transaction in under 500 milliseconds and return a decision on whether to approve or flag it.

On the impact side, Isaac asks Nicole what results merchants actually see. She points to Lenovo as a strong example. “What we’ve done for them is really reduce their fraud problem and allow them to increase their sales by 4 to 5%,” she says — a result that surprises many companies who expect fraud providers to only save money, not grow revenue.

The conversation shifts to returns, which Nicole describes as “a moment of truth” with customers. Merchants want to offer instant refunds because it creates goodwill and drives repeat purchases. The problem? Fraudsters will ship rocks — literally. Signifyd’s Instant Refunds feature uses the same network intelligence to assess a customer’s return history across merchants, so a first-time returner isn’t penalized unfairly, and a known abuser doesn’t walk away with an immediate payout.

Nicole also weighs in on agentic commerce, one of the hottest topics on the Shoptalk floor. Her take is measured and refreshingly practical: “I think we’re almost through the first hype cycle on agentic.” She notes that most people, herself included, are still using AI for discovery and research — not to make purchases on their behalf. Signifyd is already working on protocols to ensure that legitimate shopping agents aren’t blocked the same way that malicious bots have historically been.

For smaller merchants — the kind who might have one person named Katie manually reviewing suspicious transactions — Nicole’s message is clear: that approach doesn’t scale. “As you’re growing, you’re gonna have to hire a lot more Katies. Katie’s not gonna get to sleep.” Signifyd integrates directly with Shopify, WooCommerce, and Magento, making it accessible for growing businesses well before they hit enterprise scale.

Final Thoughts

What makes this episode stand out isn’t just the technology discussion — it’s the framing. Nicole consistently brings the conversation back to the customer. Fraud protection, in her view, isn’t a defensive function bolted onto the back of an e-commerce operation. It’s woven into every touchpoint: account creation, login, checkout, and yes, the return. Signifyd provides an end-to-end Commerce Protection Platform that leverages its Commerce Network to maximize conversion, automate customer experience, and eliminate fraud and customer abuse for retailers.

That’s a fundamentally different value proposition than simply stopping chargebacks. And for merchants still relying on manual review — one Katie at a time — the question worth asking is this: in a business where every good transaction counts, can you really afford to let fraud protection be the thing that signs off on your growth?
