Ben Dilts co-founded Lucidchart, now Lucid Software, with Karl Sun. He built the first prototype of the browser-based diagramming tool.
The first release was in December 2008. Lucidchart, LLC was formed in Utah in April 2009, and the company incorporated in Delaware as Lucid Software Inc. in January 2011.
In 2010 the product joined the Google Apps Marketplace. A 2011 seed round raised $1 million.
Lucid launched Lucidspark in 2020 and reached a $3 billion valuation in July 2021. Dave Grow became CEO in April 2022 and Sun moved to board chair.
