8 Years To Fall In Love And 18 Years Of Startup Madness: The Knot's Married Founders Tell All

When Carley Roney and David Liu met, they were undergraduates at New York University. But it took eight years for them to fall in love.

"While we didn't spend much time talking to each other, we probably saw each other every weekend for a year," Liu said of the art-school program he and Roney were both enrolled in.

"Yah, and we spent two weeks together in the Soviet Union [through NYU] in which we exchanged exactly one word," Roney chimed in.

Years later, the two ran into each other at a party. Suddenly, it struck Roney: "David's kind of cute!"

After that the pair were inseparable. Within seven months, in July 1993, Roney and Liu were married. It happened so quickly, Roney says her mother was convinced she was pregnant (she wasn't).

By 1995, they had started their first business venture together, making CD-Roms for brands like the Smithsonian.

The next business they founded was The Knot, in 1996.

The Knot, now known as XO Group, is a publicly traded company with a number of lifestyle brands in its portfolio, including The Nest for new homeowners and The Bump for new mothers. Liu says 80% of women planning a wedding join The Knot.

It hasn't been easy growing a publicly-traded business together. In fact, Liu and Roney give the following advice to other couples who want to co-found a company: "Don't try this at home."

Business Insider spent an hour chatting with Liu and Roney about their 18 years in business together, and how they created a lasting wedding brand from scratch.

Here's the lightly edited tell-all:

Business Insider: Your wedding didn't go as planned—it was on a rooftop in July without air conditioning on the hottest day in 10 years. How did you end up running a wedding business, when you didn't know much about weddings to begin with?

Liu: We did something terrible in our past lives, I think.

Roney: You do whatever you do when you're in the hot seat. You call everyone you know to call everyone they know to find anyone in the industry. I did everything from calling my high school best friend's fiance's dad because he ran a veil company. I remember thinking "Oh my gosh, what are we getting into here?"

We just went about educating ourselves and learning everything about weddings. I read 20 back issues of every bridal magazine I could find.

Liu: This was 16 years ago [The Knot launched in 1996]. It was a different time. The qualities we've held as high importance to be successful are curiosity and the desire to learn. Our approach was, "It's an exciting opportunity, we see these magazines as enormous, advertising-filled products and there's clearly demand."
