27.841 - 50.541 Brian Thomas

Mike Liberty is the co-founder and chief risk officer at Signified, where he oversees risk operations and strategy and data science. In 2011, he co-founded Signified with CEO Raj Ramanand. The co-founders were inspired by the belief that online merchants were at an unfair advantage when it came to the requirement that they accept liability for credit card fraud.

50.521 - 70.977 Brian Thomas

That's not the case for in-person payments at brick and mortar stores. Before Signified, Mike Liberty was the manager of New Ventures Risk at PayPal, where he led all fraud and risk management initiatives for digital goods. Prior to joining PayPal, Liberty worked at GWC Warranty, where he was the director of business development and then chief operating officer.

70.957 - 84.076 Brian Thomas

Before that, he was an associate at Civic Partners and an analyst at J.P. Morgan. In all, he has spent more than 20 years in the finance and risk fields. Well, good afternoon, Mike. Welcome to the show. Great to be here. Awesome.

Chapter 2: How did the insight about fraud liability lead to the creation of Signifyd?

84.096 - 101.741 Brian Thomas

Thank you, Mike. I appreciate it. I know you're hailing out of the East Coast up in the New Hampshire area. I'm in Kansas City, and I know sometimes it's hard to traverse Kansas. calendars, time zones, et cetera, PR, all that. It takes a lot of work to get here. So thank you. I appreciate it. And Mike, if you don't mind, let's just jump right into your first question.

0

102.462 - 111.074 Brian Thomas

You've built a career across finance, risk management, and entrepreneurship from JP Morgan to PayPal, and now co-founding Signified.

Chapter 3: How does Signifyd protect merchants while enabling growth?

111.295 - 114.848 Brian Thomas

What experiences shape your journey to where you are today? Yeah.

0

114.868 - 132.249 Mike Liberty

So as you said, I started my career in finance. And after four years of that, I was kind of looking to make a transition to technology. And so I went to one of the portfolio companies that the private equity firm that I was working for owned and started working there. It was in the insurance industry.

0

132.309 - 153.799 Mike Liberty

And basically that was my first exposure to tech because I built out the business intelligence system for them. And So that like gave me a picture into all the inner workings of the operations. And then I knew I wanted to get into tech, but I didn't really have a background to get there. So went to business school and then coming out of business school, got hired at PayPal.

0

154.5 - 162.051 Mike Liberty

And interestingly, I think the only reason the guy who hired me over there was because I had a passion.

0

162.031 - 184.95 Mike Liberty

minor professional career playing blackjack and he was hiring me into a role that was fraud detection and so I was used to the cat and mouse game that you played with casinos and can it could put my my feet in the shoes of the fraudsters like so to speak although I wasn't breaking any laws but similar cat and mouse

Chapter 4: What challenges do merchants face during explosive growth regarding fraud?

184.93 - 205.778 Brian Thomas

That's very cool. I love the backstory. Obviously, working in the space that you were doing in finance, there's a lot of risk and we'll talk about that. But finance and risk management and that really played a role into your hiring. And I see that a lot from time to time where people have done something specific, whether they were a professional esports gamer, right?

Chapter 5: How does Signifyd balance fraud prevention with customer experience?

205.918 - 223.386 Brian Thomas

They got hired into something because something was relatable there with the business. So thank you. Mike, at Signified, you set out to solve a fundamental imbalance in e-commerce fraud liability. What was the highest, I should say, what was the insight that led you and your co-founder to build that company?

0

223.887 - 244.171 Mike Liberty

Yes, I guess I was benefiting from a little bit of ignorance when I joined PayPal into that fraud detection team. And what I did was... head up digital goods fraud there. And one of the things that just struck me was I had never considered the possibility that the merchant would actually end up taking the liability for fraudulent orders or fraudulent transactions.

0

244.752 - 271.968 Mike Liberty

And that just seemed backwards to me. It's like, why would I as a merchant have to set up an intricate fraud detection system? And that led me to only spend a brief time at PayPal because I was like, all right, well, this is fundamentally broken for all these different merchants. And it struck me as very unfair as well. And so after about a year there, Raj and I left and we started Signified.

0

272.008 - 290.033 Mike Liberty

And I would say that kind of pulled together the various parts of my background because I Coming again from that blackjack background, the finance background, I kind of saw how you could leverage additional information to get an edge. And in this case, it was an edge over fraudsters.

0

291.215 - 305.093 Mike Liberty

And then from the finance and insurance background, it was, all right, well, we can actually do this profitably where we're protecting a merchant and guaranteeing them, providing them that certainty about what the cost is actually going to be.

Chapter 6: What role does AI play in the future of fraud prevention?

305.574 - 327.883 Brian Thomas

Thank you. Appreciate that. And again, there's always a challenge, a problem, a gap in the market that entrepreneurs like yourself have found and say there's a better way to do this. In this case, obviously, putting the onus back on others for the fraud. And really, that gap is why which led to your founding of Signify, which is pretty cool. I appreciate that.

0

328.445 - 339.576 Brian Thomas

Mike, Signified focuses on protecting merchants while enabling growth. How do you balance fraud prevention with creating a seamless customer experience?

0

339.708 - 361.959 Mike Liberty

Yeah, so we started out in the mid-market and what was really fascinating there was a merchant would run into a fraud problem really right at the moment that they were experiencing explosive growth. So your product takes off, let's say, and... you suddenly become a target for fraudsters and aren't equipped to deal with it.

0

Chapter 7: How do fraudsters adapt to new technologies and tools?

361.98 - 383.954 Mike Liberty

So it was kind of intrinsic in the business that you don't want to shut down that growth, which would a lot of these middle market merchants that were growing explosively we're facing. And so like from the very beginning, it was, well, we don't want to stop these good buyers that are actually making this person's business successful, but what we need to do is prevent the fraudsters.

0

384.014 - 408.981 Mike Liberty

And so then as we've moved up market over time, it was already built into our DNA, so to speak. We never came in at it as simply fraud people. And what we always say is it's easy to stop all fraud. you just stop taking orders. You lose the plot there. The whole point is that you want to protect the orders while allowing those good buyers in.

0

409.121 - 430.262 Mike Liberty

And so what we often would tell people, and we still tell people who join my team in risk, is you've got to look for the good in these orders. So tell the story of why a buyer is making this purchase. Search for that reason. And then everything that remains, you could take a deeper look at. But what

0

430.242 - 437.452 Mike Liberty

What we really, really want to do is make sure that we're not putting undue friction in front of that good buyer.

0

437.472 - 438.494 Brian Thomas

Thank you.

Chapter 8: What can we expect in the future of digital commerce and risk management?

439.034 - 458.882 Brian Thomas

I appreciate that. And yeah, unfortunately, as companies start to have that growth and starting to get more exposure, obviously that attack surface, right, from fraud or cyber, it doesn't matter. You're just more of a target. And I really appreciate what you all are doing in this space to help prevent that.

0

458.862 - 471.157 Brian Thomas

And Mike, the last question of the day, as we look ahead to the future, how do you see the future of fraud prevention, digital commerce and risk management evolving? And what role will AI play in shaping this landscape?

0

471.718 - 496.742 Mike Liberty

Yeah, so throughout my career in the space, and now it's 15 years ago since we started Signified, I would say that There has been a lot of tools that have come around that claim to be the silver bullet that are just going to stop fraud entirely. And I think what that misses is that the fraudsters adapt as well. So they become innovative. Those tools are all available to them.

0

497.443 - 519.868 Mike Liberty

And often they're the early adopters of a lot of these tools. And so what I think is going to happen is that continued arms race where now you've got this intermediary, whether it's OpenAI or Anthropic or one of these big foundational model providers that are making agentic commerce available. And

0

519.848 - 543.716 Mike Liberty

It's really difficult to kind of pierce the veil of that agent, especially because these guys are, they're looking to acquire customers. And so fraud kind of tends to be, safety tends to be an afterthought. And so they don't think about, all right, well, we've got to make sure that we put the information about whoever is sitting behind that agent front and center.

543.817 - 565.431 Mike Liberty

So it's available to a merchant and so that they can make a decision. And that's where like someone like Signified really comes in because we're at that cutting edge. We know these these fraud patterns and we're constantly thinking about, all right, how do we provide that protection while enabling this completely new form of commerce?

565.411 - 586.812 Mike Liberty

As I said before, I think it all goes back to the informational edge that you can get over a fraudster. Fundamentally, we're using all of this information to basically figure out what is the intent of that buyer, what is the identity of that buyer.

586.792 - 611.582 Mike Liberty

We're able to be creative, see across our entire network and pull all of that information together to make sure that we're approving the good buyers and also like staying on top of the adoption of fraudsters of all of these new tools. And the last thing I'd be like, it just is such an exciting time to be in tech with where AI is going.

611.682 - 626.687 Mike Liberty

I mean, you can build stuff so quickly these days, quicker than I ever could in my career. And that just accelerates what we are able to bring to our merchants in terms of tooling and our detection capabilities.
