Lingumi's take on their challenges in 2021

In 2020, we grew the team from 10 people at the start of the year, to 60 people by the end of the year. It's been exciting to see such amazing talent to join our team and our revenue skyrocket this year (10.7x year to date).

In 2021, we plan to develop many more effective courses and drive further growth in our biggest markets as well as explore new markets to break into.

Our take on Lingumi

Freddie headshot
Freddie
Company Specialist

Lingumi was developed to increase access to learning a second language, based on research that a child’s earliest years present a ‘magic window’ to do so. The learning method is digital and unique, focusing on ‘edutainment’, placing it very favourably in the growing EdTech market.

Lingumi grew significantly over the past few years, and did well to capitalise on the increasing trend for at-home learning. At one point they were top of the Kids section of the App Store in Taiwan, overtaking Peppa Pig. The app delivers a single lesson per day of around 20 minutes designed to be effective even if the parents themselves don’t speak English, opening Lingumi up to the international market.

It already has customers in over 40 countries, but is mainly focused on Western Europe, Taiwan and China, the latter being a potentially huge market which Lingumi hopes to tap into by leveraging its existing learning method and content in Chinese kindergartens.

The panel's take on Lingumi

Saul Klein headshot
Saul Klein
Co-founder and Partner at LocalGlobe

Lingumi is an edtech company, bringing the world's best teaching experience to pre-school children around the world, through technology. Lingumi's first course teaches foundational spoken English, to families around the world, particularly in China and Taiwan.

The platform offers the benefits of private tuition, but at lower cost; instead of repeatedly delivering live classes, Lingumi Teachers deliver daily lessons asynchronously to families, whenever they want to learn, using their proprietary voice, video, and play-based teaching tools. The company's revenue has grown over 500% in the last 12 months, with over 100,000 families learning English using their first course.
