About us
Our mission isto become the de facto way people learn foreign languages. We begin by teaching the next billion people English and Spanish.
Please make an application promptly if you are a good match for this role due to high levels of interest.
English is the global language of business, culture, and communication, and over 1.5 billion people around the world are actively trying to learn right now. Others dream of communicating with the half-billion native Spanish speakers across the globe. The problem is that it's nearly impossible to learn tospeaka language without constant access to a speaking partner. Grammar and vocab apps don't really help – you need to actuallyconversewith someone.
Speak is on a journey to fix this. We're creating an AI-powered experience that replicates the flow of a conversation,withoutneeding a human on the other end. The goal is to make it radically more accessible to be able to have conversations in a foreign language and eventually help hundreds of millions of people gain fluency who otherwise wouldn't be able to.
We started on this journey over five years ago and we've still got a long ways to go. We're thoughtfully adding new team members only when we think they can truly play a big role in our mission.
Speak launched first in South Korea where we have quickly grown to become the top grossing education app in the country. We have now delivered this winning product to more than 30 countries globally and are continuing to expand to more markets in the coming months. The company is well funded, raising a recent Series B backed by investors like OpenAI, Founders Fund, Y Combinator, Khosla Ventures, Lachy Groom, Josh Buckley, and others. We’re a team of 50 based primarily in SF, Seoul, and Ljubljana.
