Cardinal Peak vs L&T Technology Services: overview

Cardinal Peak

Cardinal Peak has built connected devices out of Lafayette, Colorado since 2002, covering electrical design, embedded firmware, cloud back ends and mobile apps. Its longest-running specialities are audio, video and connected home products. FPT Corporation, the Vietnamese IT group, acquired it in November 2023, adding about 100 experts and a US office to FPT's North American business; Cardinal Peak now describes itself as a wholly owned FPT subsidiary. The acquisition gives it access to FPT's offshore capacity for larger programmes.

L&T Technology Services

L&T Technology Services (LTTS) is the listed engineering services subsidiary of India's Larsen & Toubro group. It reported more than 23,600 employees at the end of 2025, across 22 global design centres.
