We are revolutionizing
online education

We are a team of enthusiastic teachers, designers and programmers who are passionate about bringing the benefits of online education to young learners all over the world.

How we work

We take the hassle out of teaching. We connect teachers with online English teaching opportunities, make sure that our teachers are provided with a curriculum and resources, and offer flexible hours, competitive pay, and teacher support.

Our intuitive Open whiteboard technology livestreams lessons directly into students’ homes. It’s free to use, and is designed to make teaching easier for our teachers, and more effective for our students.

Our purpose

We believe that teachers have the most important job in the world. Every day teachers work incredibly hard to inspire students, transform lives, and shape childrens' futures. We want to help teachers to find the life-work balance that they deserve.

We do this by simplifying online teaching, and offering our teachers flexibility, tools, and support. This gives our teachers the freedom to focus on the things that matter, like students, friends, and family. And because happier teachers make better teachers, everybody benefits.

Our story

We are a close-knit team of teachers, designers, and programmers based in Cambridge, UK. We started out in 2013 with the dream of bringing online education to every country on the planet.

We’ve gone on to develop our own online teaching platform: the TwoSigmas Open Whiteboard. In 2015 we were awarded the MassChallenge Gold award for our innovative work in the Edtech field. Since we started, we’ve helped to deliver online lessons to thousands of learners around the world.

You - ESL teacher

Our teachers are the most important part of the team. They inspire us with their passion, skill, and dedication every single day.

Our technology

In early 2015 we set ourselves a challenge. We wanted to find a way to improve online teaching while simultaneously making our teachers’ lives easier. Our eggheads got to work and came up with the Twosigmas Open whiteboard, our state-of-the-art online classroom. It’s the perfect tool for enhancing lessons, and it’s part of the toolkit that we provide to all of our teachers.


Illustrate your point: you and your student can draw and write together in real time. Share and annotate images, pdfs and more.


With high quality camera and microphone support, you’ll soon forget that you and your student are on opposite sides of the world.
