Relay evolved from within Republic Wireless, a spin-off of Bandwidth (BAND), which pioneered the concept of a WiFi-first mobile carrier and became Consumer Reports top ranked prepaid cell phone service in multiple years. The company is led by experienced entrepreneurs Chris Chuang (co-founder and CEO) and Jim Mulcahy (co-founder and President), with its rapid growth recognized several years in a row by the Inc 5000 list of fastest growing private companies, the Deloitte Fast 500, and more. As of 2026, the Raleigh, NC headquartered company employs nearly 300 Relayers and has been named as one of the 50 Best Places to Work in the Triangle for 2026.

Relay has raised more than $90M in total funding from investors including Wind River Ventures, G2 Venture Partners, Cerity Partners, International Paper, Harmonic Growth Partners, Sovereign’s Capital, and Thayer Investment Partners among others.
