Clockwise is an intelligent calendar assistant that frees up your time so you can work on what matters.

Clockwise is building intelligent calendar software that is revolutionizing the way teams spend their time.

Clockwise was co-founded in 2016 by Matt Martin, Mike Grinolds and Gary Lerhaup. The company is headquartered in San Francisco, California.

Clockwise transforms people’s days, turning what they have — 15 minutes to work here, 30 minutes there — into what they need.

Clockwise uses AI to understand your work and life commitments and automatically organize your calendar to help you focus on your priorities. It creates uninterrupted blocks of time to get things done and takes the stress out of complex scheduling across teams, double bookings and so much more.


Clockwise has put back thousands of hours of time into the world's most innovative teams, like Lyft, Asana, Coursera, Twitter, Intercom, and many more. It has optimized more than 200,000 calendars for workers.


Clockwise is backed by Accel, Greylock Partners, Bain Capital Ventures, Slack Fund, SV Angel and others. The company raised $18M in Series B round on June 15, 2020. This brings Clockwise's total funding to $31.6M to date.
