Justin Rosenstein

Rosenstein graduated from Stanford with a degree in mathematics and worked at Google as an engineer and product manager on Gmail and Google Drive before leaving in May 2007 for Facebook, where he was an engineering lead. That mix of consumer product work and internal tooling shaped Asana's insistence on fast, low-friction interfaces for software bought by departments rather than by developers.

Justin Rosenstein is a US software engineer and entrepreneur who co-founded Asana with Dustin Moskovitz. At Google he worked on Gmail and Google Drive; at Facebook, which he joined in May 2007, he was technical lead for Facebook Pages, the Like button and Facebook Beacon. He and Moskovitz built the internal Tasks tool that became the basis for Asana, left Facebook in 2008 to found the company, and Rosenstein led product and design direction, including the Work Graph model and the interface conventions that made Asana usable by non-technical teams. He later stepped back from day-to-day work at the company and has spoken publicly about the attention costs of the consumer products he helped build.

Justin Rosenstein was born in 1983 in Alameda County. Education: The College Preparatory School.
