Cambly lets people practice English through on-demand video chats with native-speaking tutors.
Cambly is an online English-learning service built around one simple idea: if you want to get good at speaking a language, you have to actually talk to people. Students open the app or website, tap a button, and within seconds get connected to a native English speaker for a live video lesson. No scheduling, no waiting for a weekly class — just instant conversation practice, any time of day.
The tutors are the engine of the whole thing. Cambly recruits native English speakers from around the world and lets them work flexible hours from home, picking up lessons whenever they're available. The company doesn't own classrooms or employ a big teaching staff in the traditional sense; it runs a marketplace that matches tutors with learners who want to talk. Students pay for access — typically a subscription for a set number of minutes or unlimited chatting — and tutors get paid for the time they teach. Cambly sits in the middle and takes its cut. That model lets it offer round-the-clock lessons across time zones without building a single school. For learners, the pitch is convenience and real conversation rather than textbooks or grammar drills. Many customers are adults in countries like Brazil, Japan, Turkey, and Saudi Arabia who want to speak more naturally for work, travel, or study. Cambly also sells to businesses that want to improve their employees' English. Its competitors range from human tutoring marketplaces like Preply (private) and italki (private) to app-based giants like Duolingo and Berlitz (private), though Cambly's on-demand, no-booking twist is its main differentiator.
The company was founded in 2012 in San Francisco by two friends, Sameer Shariff and Kevin Law, who got the idea after Shariff's experience learning Portuguese and seeing how much real conversation mattered. Cambly has stayed privately held and raised relatively modest outside money, which means it has had to build a real business rather than lean on endless venture funding. Its strengths are a large pool of flexible tutors and a product that's dead simple to use; its vulnerabilities are thin switching costs, heavy competition, and the challenge of keeping tutor pay and quality consistent as it grows.
