Trippy

Trippy is a social and mobile friend-sourced tool launched in September 2011 founded by technology entrepreneur J.R.

"[2][3] The app ties into users' social networks, such as Facebook, to discover which friends, family and contacts have visited the considered destination—whether it be that they've checked-in, lived, worked, or studied there.

[4] Through one-click recommendations and Facebook-style commenting, Trippy lets friends suggest what hotels, restaurants, and destinations would be a good fit.

[7] On November 15, 2011, Trippy announced its first round of seed funding, equaling $1.75M,[8] co-led by Sequoia Capital and True Ventures.

SV Angel also participated, along with individuals including Rob Solomon, Tim Ferriss, Brian Lee, Gil Ebaz, Brandee Barker, Chase Jarvis, Randi Zuckerberg, Jason Mraz, and Rachel Zoe, as well as others.
