Who Owns SiTime?

Understanding SiTime's ownership is key to its market position. Its IPO in November 2019 marked a significant shift, providing capital for growth and innovation.

SiTime, a leader in silicon MEMS timing solutions, was founded in 2005. Its products are vital across enterprise, automotive, and consumer markets.
