Peek today expanded its service to the East Coast, with service now provided for New York, Miami, and Orlando. Peek started as a service to take the pain out of travel plans by helping travelers efficiently find things to do in their destination with services like the “Perfect Day Builder,” that shared tips and ideas from other users and the web. Though the service was initially limited to the San Francisco Bay Area, San Diego, and Hawaii, the company has reported over 100% average monthly growth in bookings since October, and is so popular that it’s offering users micro-level integration with its cities: for instance, it offers tours of Brooklyn’s breweries, the High Line’s food trucks, a red-carpet experience at TriBeCa Film Festival, a “Sleep No More” package, and more. The real advantage is its curatorial edge, and in response the company has raised over $1.4 million from investors including Twitter and Square co-founder Jack Dorsey, Google’s Eric Schmidt, SV Angel, and Khosla Ventures.
