## Summary

Lucid Software's official About page and corporate press materials identify Karl Sun as a co-founder and CEO of the company. The site describes Lucid as the maker of Lucidchart and Lucidspark, headquartered in South Jordan, Utah, and founded in 2010. Company-level claims about user scale (70M+ users) and enterprise penetration (Fortune 500 usage) appear in press releases and company descriptions tied to funding announcements, most notably the 2021 Series E.

Supplementary public record includes press coverage of Lucid's fundraising milestones — particularly the reported $500 million Series E at approximately $3.2 billion valuation (2021) — in publications such as TechCrunch, the Wall Street Journal, and Silicon Slopes Magazine.

## Useful Claims

- Karl Sun is listed as co-founder and CEO of Lucid Software.
- Lucid Software was founded in 2010; headquartered in South Jordan, Utah.
- Co-founder alongside Ben Dilts; Dave Grow identified in legacy notes as an executive (current title not confirmed here).
- Sun previously worked at Google in legal and product roles before co-founding Lucid.
- Products include Lucidchart (cloud diagramming) and Lucidspark (virtual whiteboarding).
- Company has reported 70M+ users globally and broad Fortune 500 penetration (company claim, not independently verified here).
- 2021 Series E: reported at $500 million raised, approximately $3.2 billion valuation; multiple press sources cited this figure at announcement.
- Lucid Software has not gone public as of this writing; it remains one of the largest Utah private software companies.
- Sun is an active presence in the Silicon Slopes community.

## Reliability Notes

The Lucid official website is a marketing source. User-count, Fortune 500 penetration, and valuation claims should be cross-referenced against third-party press coverage and investor announcements. The 2021 Series E valuation was widely reported but is based on private-round disclosures, not public market pricing. Dave Grow's role and current executive structure should be verified against recent Lucid press releases rather than legacy intake notes.
