US-based privacy-first telecom startup Cape has secured $100 million in a Series C funding round, as it looks to redefine mobile connectivity with a security-first architecture. The round was co-led by Bain Capital Ventures and IVP, with participation from 01 Advisors, 137 Ventures, Definition, and Fifth Down Capital. Founded in 2022 by John Doyle, Cape is building a fully independent mobile network infrastructure, rather than relying on traditional telecom operators. This allows the company to embed privacy and security directly at the network level, addressing vulnerabilities inherent in legacy systems. Unlike conventional mobile virtual network operators (MVNOs), Cape operates its own mobile core and SIM infrastructure, enabling features such as daily identifier rotation to prevent tracking and enhanced protection against surveillance and interception attacks. The company’s solution is gaining traction among government agencies, enterprises, and privacy-conscious users, especially amid rising concerns over large-scale telecom breaches and data exposure incidents globally. With this fresh capital, Cape plans to accelerate adoption across enterprise, government, and consumer segments, while continuing to invest in R&D to strengthen its secure mobile ecosystem. As cybersecurity threats evolve, Cape is positioning itself as a new category leader in secure telecom infrastructure, challenging traditional carriers by offering privacy as a foundational layer rather than an add-on.
