Why this entity matters
SiTime is on the Technical University of Munich's August 2026 list of unicorns founded by TUM alumni, supplied to Startuprad.io by UnternehmerTUM's press office in October 2026. Co-founder and CTO Markus Lutz holds a TUM engineering diploma. SiTime was never a private unicorn: it passed $1 billion in market value as a listed company, so its place on the list reflects market capitalisation. No UnternehmerTUM programme or UVC Partners investment has been documented.
