Cape raises $100M Series C to power private and secure mobile connectivity for enterprises, government, and consumers. Backed by new investors, Cape is building deep infrastructure to rival traditional telecommunications carriers across multiple sectors ARLINGTON, Va.-(BUSINESS WIRE)-Cape, America's leading privacy-first mobile carrier, today announced it has raised a $100M Series C co-led by Bain Capital Ventures and IVP, with participation from new investors, 01 Advisors, 137 Ventures, Definition, and Fifth Down Capital. Cape has built a carrier from the ground up to protect U.S. government agencies, businesses, and privacy-conscious individuals against cellular security threats. "Cell phone networks track everywhere you go, every app you use, every person you call or text," said John Doyle, CEO of Cape. "So when they're compromised, it leads to some of the most sweeping and damaging violations of both national security and individual privacy in history. There's no app, no add-on that fixes problems inherent in the underlying cellular network itself, so we've redesigned a telco from scratch to close this gap." Nearly every government agency, enterprise, or consumer in the United States gets their cell phone service from one of three main mobile carriers that resell their services to dozens of smaller brands. Those carriers have faced repeated security failures, including the "Salt Typhoon" cyber espionage campaign, described by U.S. officials as one of the most significant intelligence breaches in the nation's history, which reportedly compromised the phones of Donald Trump and J.D. Vance. Separately, a 2024 breach exposed the call records of nearly one in three Americans to the dark web. The major carriers have also faced $200 million in FCC fines for selling customers' location data without proper consent. "The mobile carrier market has been effectively frozen for decades, dominated by a small number of incumbents running legacy infrastructure," said Saanya Ojha, Partner at Bain Capital Ventures. "Cape is the first company we've seen that is willing to challenge that foundation - not as a reseller, but as a true infrastructure builder. By operating its own mobile core and embedding privacy at the network layer, Cape is building the inevitable future of secure mobile infrastructure." Cape is a mobile virtual network operator, or MVNO, meaning it leases the use of physical towers from the traditional operators, but unlike other MVNOs the company has built and runs its own mobile core and SIMs. This infrastructure enables privacy-enhancing features like Identifier Rotation, which changes SIM ID numbers every day to disrupt persistent tracking, and Secondary Numbers, which allows customers to use multiple phone numbers on a single SIM. Since its founding in 2022, Cape has been adopted by U.S. national security professionals, enterprise executives, journalists, activists, and everyday people across the country who reject the privacy and security risks that come with using a traditional mobile carrier. The latest funding enables Cape to speed adoption across government, businesses, and consumers, while supporting further research and development. "It's rare to see a product with such universal value across government, enterprise, and consumer," said Somesh Dash, General Partner at IVP. "This is an investment in deep infrastructure that secures the connectivity backbone of our mobile economy and way of life. By building a new telco with its own software stack, rather than just reselling the service of incumbents, Cape is the only credible alternative to the traditional carriers."

RiPSIM and Cape announce strategic partnership to deliver us-sourced SIM credentialing. Partnership combines cloud-native SIM credentialing with secure mobile service innovation to redefine privacy, control, and speed in telecom ASHBURN, Va.-(BUSINESS WIRE)-RiPSIM Technologies, makers of the world's first cloud native software platform for generating and delivering mobile network authentication credentials on demand, today announced a strategic partnership with Cape, the pioneering privacy-first mobile carrier, to deliver full-custody, U.S.-sovereign SIM credentials to consumers, enterprises, and government customers. "Together with Cape, we are building a software-driven telecom ecosystem where privacy, control, and agility are designed into the foundation." - Chris Jahr, Founder and CSO of RiPSIM. Share Traditional SIM credential generation often relies on outsourced facilities across multiple global locations, increasing supply chain risk and limiting operator visibility and control. RiPSIM was founded on a different principle: mobile credentials should never be outsourced and should be owned and controlled by the operator running the network. Its U.S.-developed software platform enables operators to generate, manage, and safeguard SIM credentials within their own secure cloud environments, ensuring full customer custody and keeping credential creation and management within U.S. borders. Cape has built a software-defined telco to address modern threat landscapes that legacy telecom infrastructure was never designed to handle. SIMs and authorization are critical to security. As adversaries increasingly exploit vulnerabilities in our networks, global supply chains, and outdated provisioning systems, Cape and RiPSIM are approaching the problem from complementary sides of the telecom ecosystem to enable the US-sovereign management of secure service. Together, the two startups are modernizing telecom security by giving network operators and their customers complete ownership and control over mobile credentials. The partnership integrates RiPSIM's cloud-based credentialing platform into Cape's secure, software-first mobile infrastructure, creating a sovereign alternative to legacy SIM provisioning models. By moving credentialing into a cloud-native environment and eliminating traditional supply chain risks associated with offshore delivery, Cape gains the speed and operational flexibility to rapidly deploy new SIM-based innovations and advanced privacy and security features. The combined solution is especially valuable for organizations where credential integrity is mission-critical, such as enterprises with sensitive communications needs, and government agencies requiring sovereign telecom infrastructure. "What makes our platform unique is that we move SIM credentialing fully into the cloud and give our customers complete control," said Chris Jahr, Founder and CSO of RiPSIM. "Credentials remain within their geographic jurisdiction and under the direct custody of the network operator, not outsourced to offshore facilities. That shift strengthens security while modernizing how the industry approaches trust. Together with Cape, we are building a software-driven telecom ecosystem where privacy, control, and agility are designed into the foundation." Cape has begun integrating RiPSIM's credentialing technology within its production offerings and has continued plans to expand. "Both Cape and RiPSIM were founded to challenge decades-old telecom assumptions and address modern security threats with a software-first approach," said John Doyle, CEO of Cape. "By integrating RiPSIM's technology into our product, we are delivering a U.S.-sourced, cloud-based solution built for speed, agility, and stronger privacy protections. This partnership accelerates our ability to innovate and bring meaningful security improvements to the market." RiPSIM will be exhibiting at Mobile World Congress 2026 at Hall 8.1 - 4YFN, Stand 8.1D20.7, March 2-6 to be held at Fira Gran Via, Barcelona.
