Our Story

In 2001, Accertify’s President Mark Michelon was an accountant at Orbitz. Faced with mounting chargebacks, Mark was asked to become a fraud analyst overnight. 

The first chargeback memo he opened showed a flight purchased from JFK to Accra, Ghana, on a credit card with a California billing address. “That doesn’t look right,” Mark thought to himself, and opened the next one. It was in that emotionally overwhelming pile of memos that the concept of Accertify was born. 

In 2007, Mike Long and a group of other travel industry executives brought that concept to life. And that’s when Mark came on board. Together, they built a platform that pulled together multiple sources of data into a single picture of every transaction, giving fraud teams what they’d never had before: the information and the tools to make a better decision about risk. 

The first fraud Accertify ever caught? It was on a pair of tickets to a performance of Wicked in Los Angeles, on behalf of Ticketmaster. 

In 2010, Accertify was acquired by American Express, which gave it the global reach to serve the world’s leading brands. In 2024, it was carved out of Amex and began its next chapter as an independent company backed by Accel-KKR.  

That next chapter has a name: More Yes. 

More Yes to revenue. 
More Yes to legitimate customers. 
More Yes to growth. 

For too long, your fraud and risk teams have been the departments that say “no.” 
“No” to the new channel. 
“No” to the bold new campaign. 
“No” to the ambitious program. 
Not because they wanted to, but because they couldn’t be certain they could enable growth without the wrong people coming along for the ride. 

Accertify’s Predictive Yes Platform changes all of that. It joins signals across the entire customer lifecycle – combining unmatched data volume, adaptive machine learning, and a data consortium of the world’s most recognized brands – to give your risk teams the confidence to Say Yes to More. 

The people behind Accertify spent years managing fraud risk inside large organizations before building a better answer. They know what it feels like to be measured on decisions that cut both ways. That experience is in the platform, in the models, and in the team that works alongside yours. 

Not a reckless yes. A precise, data-backed yes. A confident yes. 

More Yes. That’s the Accertify story.
