Onoff Telecom is a cloud-based telecommunications company that provides virtual mobile numbers through mobile apps, serving both individuals and businesses. Its products include Onoff, an app for individuals to obtain a second mobile number without a physical SIM, and Onoff Business, a dematerialized telephony solution for companies to manage team numbers via a single invoice[1][3][4]. Onoff solves the problem of needing multiple phone numbers by storing them in the cloud, combining app simplicity with traditional telecom reliability, powered by 4 patented technologies; it operates as a licensed telecom provider in 21 countries, offering numbers from up to 33 countries, with over 2 billion messages exchanged and €30 million raised for global expansion[1][3][4]. The company targets frequent travelers, multi-number users, and businesses seeking flexible, cost-effective telephony, showing strong growth with 120 employees across offices in Paris and Tallinn[1][4].
Onoff Telecom was founded in 2014 by Taïg Khris, a former extreme sports athlete turned telecom innovator who questioned reliance on physical SIM cards in a tech-advanced industry[1][3]. Khris, a self-taught telecom expert, envisioned "cloud numbers" and assembled a team, including a skilled CTO from Estonia's tech hub—home to unicorns like Skype, Bolt, and Wise—to develop the backend[3]. Early traction came from disrupting the need for second subscriptions or phones; the app launched as a game-changer, leading to rapid scaling, B2B product development, and over €20-30 million in funding, with pivotal growth in licensed operations across 21 countries[1][3][4].
(Note: A separate German firm named onoff, focused on industrial automation since 1988, is unrelated and was majority-acquired in 2022[2][5].)
Onoff rides the cloud telephony and eSIM trend, shifting telecom from hardware-bound SIMs to agile, app-based services amid rising remote work, digital nomadism, and global connectivity demands[3]. Timing aligns with 5G rollout and post-pandemic virtualization, reducing environmental impact via cloud efficiency while challenging incumbents in a €1T+ industry[1][3]. Market forces like exploding data usage (2B+ Onoff messages) and Estonia's unicorn ecosystem favor its expansion, influencing the sector by proving scalable virtual numbers for businesses and individuals, potentially accelerating VoIP adoption worldwide[3][4].
Onoff is poised for hypergrowth through geographic expansion and B2B penetration, leveraging its €30M funding to deepen 21-country licenses and add numbers[1][3]. Trends like AI-driven call management, Web3 identity, and zero-SIM ubiquity will shape its path, with potential for enterprise partnerships or IPO as cloud telecom matures. Its influence may evolve from disruptor to standard-setter, empowering a borderless mobile future—echoing Khris's vision of cloud numbers as the SIM's successor.
Onoff has raised $21.0M in total across 4 funding rounds.
