OpenDoor just closed a $9.5 million round. The list of angel investors involved, is literally quite insane:

• Paypal co-founder Max Levchin
• Former YouTube and Facebook CFO Gideon Yu
• Eventbrite co-founder Kevin Hartz
• Y Combinator’s Sam Altman
• Quora CEO Adam D’Angelo
• Yammer co-founder David Sacks
• Angelist’s Naval Ravikant
• Yelp CEO Jeremy Stoppelman
• Box CEO Aaron Levie
• Initialized Capital’s Harjeet Taggar, Garry Tan and Alexis Ohanian
• Former Twitter vice president Elad Gil
• Blippy co-founder David King
• Flixster co-founder Joe Greenstein
• Angel investor Mike Greenfield
• Quora co-founder Charlie Cheever
• Path’s Dave Morin
• Facebook vice president Dan Rose
• Trevor Traina
• Resolute Ventures’ Mike Hirshland
• Caffeinated Capital’s Ray Tonsing, Felicis’ Aydin Senkut
• True Ventures’ Om Malik
• Thrive Capital’s Josh Kushner
• Crunchfund’s Michael Arrington
• SV Angel.

There likely hasn’t been a real estate startup with this type of hype and backing since Zillow was founded in 2005. And, like Zillow (I took a job there without even knowing what the product was), they are very vague on exactly how their service will work.

I’ve got an idea on how I think they are going to approach solving their value prop of “The easiest way to sell your home. Receive an instant offer online and close in 3 days.” But that is another blog post…coming soon.

PS: I’m still slightly bitter about their name 🙂
