The story
Astera Labs was founded in November 2017 in Santa Clara, California, by Jitendra Mohan, Sanjay Gajendra, and Casey Morrison. While working at Texas Instruments, the co-founders observed that while processors used in data centers were getting faster, the connectivity technologies were not keeping pace, resulting in bottlenecks. The trio quit their jobs and founded Astera in Sanjay Gajendra's garage. They adopted a fabless semiconductor model, outsourcing manufacturing to partners such as TSMC.
In April 2022, the company opened a research and development design center in Markham, Ontario. It opened another design center in Burnaby, British Columbia, in September 2022.
