We revolutionize
private tuition

We are a team of enthusiastic teachers, designers and programmers, writers, engineers etc who are passionate about bringing the benefits of 1 to 1 education to young learners in China.

How we work

We take the hassle out of teaching. We connect teachers with online English teaching opportunities, provide the curriculum and resources, and offer flexible hours, competitive pay, and teacher support.

Our intuitive Open whiteboard technology brings/livestreams lessons directly into our students homes. It is 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 single day teachers tirelessly work to transform lives, shape children’s futures, and inspire future generations. We want to help teachers to achieve the life-work balance that they deserve. We simplify online teaching and offer our teachers flexibility, tools, and support. By doing this we give our teachers the freedom to focus on the things that matter, like family, friends, and students. And because happier teachers are better teachers, everybody benefits.

Our story

We are a team of enthusiastic teachers, designers and programmers who are passionate about bringing the benefits of 1-on-1 education to young learners in China.

We started in Cambridge, England in 2013, and were inspired by the work of educational psychologist Benjamin Bloom. In his 1984 paper 'The Two Sigmas Problem' Benjamin described an experiment where a teacher delivered classroom instructions and private tuition to two groups of students at the same academic level. Students receiving private tuition performed above 98% of those taught in the classroom. In nerdy math terms, they performed two ‘sigmas’ higher. We believe that every child is capable of achieving ‘two sigma’ results.

We’ve created our Open whiteboard. An online teaching platform that’s specially designed to make online lessons more convenient and rewarding for both teachers and students. Over the last few years it’s helped us to bring the twosigmas effect to thousands of young learners.

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.
