Our take
The massive amounts of data that telecom companies hold on their customers, and the various weak spots in mobile networks, offer many lucrative possibilities for hackers. With massive mobile network data breaches affecting the likes of US telecom giant AT&T, Cape is a mobile network responding with a way to reconcile personal privacy and national security.
Cape positions itself as a privacy-first mobile network, offering 5G and 4G speeds with more privacy. It collects minimal personally identifiable information from its customers as well as offering spam protection, hardened account security and firewall. The network itself piggybacks on existing cellular networks and uses advanced encryption and data protocols to protect its customers.
The company has attracted good investment and secured contracts with the US military because of the network's ability to contribute to national security. Cape only came out of stealth in 2024, though, and its first steps will be to provide its users with eSIMs. A partnership with UScellular has helped grow the company's market share, and it's now available nationwide. 2026 Series C funding is being used to further grow its customer base and accelerate R&D efforts.
