LightSource was started in 2021 by Penn and CTO Idan Mintz, while the two were working in different parts of Alphabet. Penn was at robotaxi unit Waymo, and Mintz was in the Google X "moonshot factory."
Prior to Waymo, Penn worked at Tesla when the electric vehicle maker was starting to mass produce its popular Model 3 sedans. He said that finance, sourcing and engineering professionals have to work together to find, or sometimes custom order, high-quality parts. They also have to maintain their best supplier relationships while evaluating new potential vendors and negotiating fair prices.
Often these teams rely on "hundreds of disparate processes and information that's stuck in thousands of emails, spreadsheets and randomly formatted invoices and contracts," Penn said.
