HATTIE: How does a commercial operation like this get and keep a person of your interest, your academic background, your love of research.

GALEN: Probably, quite frankly, the number one reason is Neil Clark Warren himself. I respect that man, you know, more than most anyone else in life.

But the problem, the scientific problem that we're dealing with is endlessly fascinating. It's a huge problem. It's every bit as complex as studying brain aging, and you know the human beast is endlessly fascinating and in relationships, doubly so. You have two people you're trying to predict.

HATTIE: So you're here because it's fascinating.

GALEN: It's fascinating. And the process up until this point has been one of rigor and, and integrity and to continue we need to, to always be moving on.

GREG FORGATCH: So we now have six different models, all working simultaneously when we're matching people and we're going to continue the furthering of the product development on the, on the matching model and the algorithms and what really works. Team Member: Let's take a look at the data you were talking about.

GREG FORGATCH: (Voiceover) It takes ten times to 15 times longer to complete our profile than any dating service. We then ask people to pay two and a half times what the dating service industry charges. Three times as many people are converting to eHarmony than the dating service industry. So we convert more people three to four times as many and they still pay two and a half times more than the dating service industry because of what we offer.

GALEN: We didn't play their rules either, which is part of the issue as well. I mean, the integrity that's going in -- gone into the scientific modeling is on a par with any work that's being done. But, but we didn't publish our model in journals.

HATTIE: You took it straight to the people who want to use it.

GALEN: We went to people, they're using it. And, you know, why they're using it, that's what I find a terribly fascinating question.
