US Mobile is a New York-based mobile virtual network operator that lets customers build their own wireless plans and switch between Verizon, AT&T, and T-Mobile on a single line. Branded internally as Warp (Verizon), Dark Star (AT&T), and Light Speed (T-Mobile), its 'Teleport' multi-network technology and eSIM-first approach have pushed it toward a self-styled 'Super Carrier' that now also bundles Starlink home internet. Founded in 2015 by Ahmed Khattak, it has grown from a niche unlocked-phone reseller to roughly a million customers.
Ev Kontsevoy is the co-founder and CEO of Teleport, a cybersecurity company building the identity-native infrastructure access platform trusted by organizations like Samsung, NASDAQ, and IBM. A serial entrepreneur who grew up in Siberia and studied applied mathematics, he previously co-founded Mailgun (acquired by Rackspace in 2012) before starting Teleport in 2015 to eliminate the fragmented, secrets-based approach to infrastructure security. Under his leadership, Teleport reached a $1.1B valuation with its $110M Series C, and he authored an O'Reilly book on identity-native infrastructure access management. He is now focused on defining agentic identity frameworks for the era of AI-driven enterprise infrastructure.
