History
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.[3] The trio quit their jobs and founded Astera in Sanjay Gajendra's garage.[3][4] They adopted a fabless semiconductor model, outsourcing manufacturing to partners such as TSMC.[3]
In April 2022, the company opened a research and development design center in Markham, Ontario.[5][6] It opened another design center in Burnaby, British Columbia, in September 2022.[7]
In May 2024, the company expanded operations in Taiwan to strengthen collaboration with original design manufacturers.[8]

In February 2026, the company opened a design centre in Tel Aviv and offices in Ramat Gan and Haifa. It also paid approximately $70 million to form a partnership with Pliops, in which 60 employees moved from Pliops to Astera Labs.[14]
