Y Combinator co-founder Jessica Livingston has backed some of the best-known Internet startups in recent years. Home rental company Airbnb is now valued at more than $25 billion, file-sharing service Dropbox is valued at $10 billion, and payments processing startup Stripe just earned a $5 billion valuation after Visa funded the company.
For the past eleven years, Livingston has made a career of incubating and investing in the hundreds of companies that have graduated through Y Combinator But she’s also a founder, having launched Y Combinator with her husband, Paul Graham, using their own savings to create what is now known has one of Silicon Valley’s most successful technology incubators.
These days, one of Livingston’s passions is focusing on adding more female founders to Y Combinator’s classes of a few dozen startups, and empowering women in tech to overcome some of the biases in the industry. She’s open about the fact that she’s felt many of these biases as a founder, and one of the ways she is hoping to make change is by sharing stories and advice from successful female founders and executives. Her brainchild for this effort is the Female Founders Conference, a San Francisco event for women who want to start a technology company or have started a company.
Oh, and she just announced that she’s taking a year-long sabbatical to spend time with her two young children and her husband.
Fortune sat down with Livingston for an exclusive interview about the challenges she’s faced as a founder, her advice for female founders and her ambitions for Y Combinator at the incubator’s Female Founders Conference in San Francisco.
This interview has been edited for clarity.
Fortune: Where did the idea for the conference come from?
Livingston: I had been thinking about it for a while. I wanted to create something that inspired more women to start startups and give them the confidence to take the leap. My husband, Paul, finally said you should do this, and we started the first conference three years ago.
We first started with a conference for 400 women. Every woman in the audience applies to come to the conference. Women don’t necessarily have to be a founder but perhaps they have an interest in it. There was such a massive response initially, we had to find a new venue this year. We expect 850 women this year. It’s one of the most expensive events Y Combinator does, but it’s also one of the most important.
There’s also a Facebook group for anyone who has attended the conference that is really active. Women are posting everything from interesting articles to tips on fundraising.
