We are pioneering a new category of software called Digital Optimization. Our Digital Optimization System serves as the command center for businesses to connect digital products to business outcomes. Digital optimization is emerging as a strategic investment for every company to survive in the digital-first world. Digital products are embedded in every part of our daily lives. In 2020, U.S. adults spent nearly 8 hours on average per day on digital activities. Digital has become the primary way business is done, and the ability for companies to offer compelling digital products and services has become a matter of survival. Digital products have become the center of how companies interact with customers. --- We were incorporated in the State of Delaware in November 2011 as Sonalight, Inc. and founded our Amplitude business in 2012. In December 2014, we changed our name to Amplitude, Inc. Our principal executive offices are located at 201 Third Street, Suite 200, San Francisco, California 94103. Our telephone number is (650) 988-5131 and our website address is www.amplitude.com.
