Couple sold their company for $745 million, but felt numb after: 'We just couldn't process it'

From the outside, it seemed like Mike and Kass Lazerow had made it.

It was 2012, and the couple from New York had sold the social media marketing platform they co-founded, Buddy Media, to Salesforce for $745 million. To celebrate, they had a lavish party for their employees where Mike walked out on stage to a 20-minute standing ovation, Kass says.

They were supposed to feel euphoric, yet they didn’t. Instead, they felt a “numbness,” Kass, now 54, tells CNBC Make It.

“We get into the Uber to go home … and [Mike] looks at me and goes, ‘OK, so which doctors’ appointments do we have tomorrow for the kids?’” Kass says.

Since 2007, the entrepreneurial couple who started Golf.com during the dot-com bubble had been working relentlessly on their new company. Kass gave birth to their third child just before her husband Mike, now 51, came up with the business idea for Buddy Media. She even nursed her newborn while building desks for an office.
