15Five is an inter-company employee feedback system founded by entrepreneur David Hassell that is based in San Francisco.[1][2]


Hassell, who has worked in online marketing and as an adventure-focused entrepreneur, founded 15Five in 2011.[3][4] The original idea for the company came from Patagonia founder Yvon Chouinard, who implemented a weekly "5-15 report" to keep track of his employees and business while he enjoyed his adventurous life.[1][5]

Hassell and his team implemented a system that involves employees spending "15 minutes to write the reports" while "managers spend no more than 5 minutes to read them."[6][7] Using this method, 15Five provides fast and easy communication between managers and employees using an interface that Hassell says is based on the design value of "elegant simplicity."[8][9]

In 2013, 15Five received $1 million in seed funding from venture capital firm Richmond Global, 500 Startups, and investments from individuals, including Yammer founder David O. Sacks, Ustream founder John Ham, former editor of Mashable Ben Parr, Ben Ling of Google and Xobni founder Matt Brezina.[6][10][11]
