While data breaches have executives at two high-profile hookup websites scrambling, at least one company is thriving in their wake.

Trustify— which currently only operates in D.C., Virginia, Maryland—is bringing private investigators to the masses through a simple app and website. Rather than the traditional method of paying a PI an expensive retainer, wannabe snoops can hire them by the hour.

At only four months old, the Georgetown-based company was already gaining a quick following. But dozens more people have flocked to Trustify this week after Ashley Madison, a dating website for cheating partners, was hacked, the founder says. Probably with good reason: for the past four years, D.C. has ranked at the top of Ashley Madison’s list of “least faithful cities in America,” based on the registered number of users per capita (Capitol Hill consistently ranked as the worst neighborhood.)

“We’ve been inundated with new customers since Ashley Madison came out,” Trustify founder Danny Boice said. “It’s raising a lot of new questions for people. Some people didn’t even know that it existed.”

It’s the second major incident for a hookup website in as many months. Nearly 4 million people who have Adult Friend Finder accounts had their information leaked online at the end of May after a data breach earlier in the year.

Trustify used that data to create a free online tool allowing anyone to search the database for their spouse’s email (or anyone else’s for that matter). Boice says they will do the same for Ashley Madison if that data is also released.

Last night alone, two people found positive matches using the tool. “It doesn’t actually mean that they’re cheating. It can be the onus for a frank and open conversation,” says Boice. “But in order to actually catch someone it’ll take more. And they may think, now I should probably hire a PI.”

That’s where his product comes in.

Users fill out a simple form either on the app or the website with some basic information, and then a detective gets in touch. It costs $99 for the first hour, and $67 an hour afterward (about $30 of which goes to the investigator). Boice promises transparency—often times these things will take more than one hour, but they won’t do the work until you approve it—and that all of the detectives are carefully vetted.

D.C., he points out, is brimming with intelligence experts of all kinds, and Trustify is looking to capitalize on that. In fact, they’ve hired two ex-Navy intelligence experts whose only job is to vet the private detectives they work with.

This was of critical important to Boice, whose inspiration for the company came out of his own miserable experiences trying to hire a detective in the midst of a nasty divorce.

Worried that his kids were in danger with his now ex-wife and her boyfriend, he turned to Google for help. “It was a skeezy experience. All these 1990-era websites came back,” Boice said. It took weeks for him to find a PI, and when Boice did hire someone—an ex-cop who seemed to check out—he charged $2,000, supposedly did a week of work without results, and disappeared.

Desperate for evidence he could use in court, Boice pressed on. He went through a string of PIs with bad, though not quite as egregious, results. Eventually, he found someone willing to take on the kind of piecemeal work that Trustify now offers. He paid a younger detective to essentially be on call and go check out the situation when Boice had suspicions. It worked.

“What I learned through my own experiences and wasting thousands of dollars is that PIs as a concept are very valuable. When you’re in this horrible life event, they are actually very useful and can help you get out of it,” he says. But the way they traditionally work is structured for the very wealthy, those who can afford a hefty retainer and thousands of dollars in billings. “It’s not conducive for the average consumer and there’s no reason it shouldn’t be.”

He points out that the lower price point opens up a realm of new things that ordinary people might use a private detective for: checking out a new nanny, looking into a person they’re going on a date with, and, yes, figuring out if a spouse has been cheating.

Although, the site’s marketing materials—and the founder’s own story—emphasize dark things that need uncovering or unsavory people that need to be found, Boice says that a little bit more than half of the things that people have been using the service for are actually neutral or positive.

A dying cancer patient used Trustify to track down a childhood friend and reconnect with them before they passed. Someone wanted to find their best friend from childhood to invite them to their wedding. They get a lot of people looking for high school sweethearts.

“There’s clearly this huge void in the market for this service. We hit on something where the product really applies to everyone,” Boice says. Of the hundreds of products that the serial entrepreneur has been involved with, it’s the fastest he’s ever seen consumers line up.
