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.
Eric Migicovsky is a Canadian hardware entrepreneur who invented the Pebble smartwatch in 2012, raising $10.26M on Kickstarter in the most-funded campaign of its time. After Pebble's $40M sale to Fitbit in 2016, he served as a Y Combinator partner, then co-founded Beeper — a universal messaging app that sparked a major Apple antitrust investigation before selling to Automattic for $125M in 2024. Now back to his roots, he's reviving the Pebble brand under Core Devices with fully open-source hardware and software.
