Hacker is a software engineer who has worked on a variety of projects, including the Firefox web browser.

Luis despite his early success in his works, he kept doing what he liked.

Their Mission:

Duolingo’s mission is to “make education free, fun, and accessible to everyone.

Business Model

In 2021, Duolingo went public and is now a publicly traded company. The company is valued at over $2 billion.

Duolingo IPO

Since then, Duolingo has experienced remarkable user growth, surpassing the 500 million user mark.

Their product is running on a freemium model and their business model is similar to Spotify and other dating apps

Despite growing users steeply on their platform, they are not profitable like every other tech startup nowadays

In 2022, they made $370 Million in revenue and burnt $435 Million in Expenses; hence making a loss of $60 Million

Revenue Growth:

They mainly earn through:

  1. Subscriptions: 6% of the total users of Duolingo have subscribed to PRO
  2. Advertisements

I think the way, they revolutionized the learning model, they should be Out-of-the-box for their earning model as well

Potential Income Sources:

1. Introducing Certificates for each level and these will be paid

2. Offering extra co-curricular exercises in the paid subscription

3. A private paid-only leaderboard with the TOP 5 getting some extra rewards like a Netflix subscription

  1. Rewards: Users earn points and rewards for completing lessons and streaks.
  2. Leaderboards: Users can compete with friends and other users on leaderboards.
