“How to Startup” is a new series from serial entrepreneur and investor Spencer Rascoff. Step by step, Spencer will take prospective entrepreneurs through the process of coming up with a startup, raising funding, starting a team, scaling, and, eventually, exiting. Based on his class at Harvard called “Startups: From Idea to Exit”, “How to Startup” is your guide to starting the next big thing.

Lots of startups start with an idea, but that’s not always the case. Zillow actually didn't start with an idea; it started with a team. In early 2006, a group of us left Expedia together and sat in a conference room for months trying to come up with a startup idea. We didn't know what the startup would do, we just knew that we wanted to work together outside of Expedia.

Several of us were buying houses at the time and noticed the poor quality of online real estate resources. Partly just to pass time while we waited for inspiration to strike, we hacked together Seattle's county website data with real estate MLS data and Google Maps, and we jerry-rigged a user experience that helped us buy homes. It became clear that if this worked for us, it could work for other people. We then realized that the most important piece of information about real estate was still missing: determining the value of homes. Thus, an idea was born.
