When I founded Preply in 2012, the mission was simple: help people prepare to speak confidently in a foreign language. Eight years later, I’m proud of how far we’ve come after trials, tribulations, and now triumph.
Countless hours spent brainstorming, testing and iterating have now paid off: Preply has connected thousands of tutors and students from across 190 countries worldwide. We have earned our rank as the global marketplace for online language tutoring, a service that has soared in demand even during the COVID-19 pandemic.
As a young entrepreneur myself, I know just how valuable it is to learn from others. That’s why I’m returning the favor and sharing what I believe are the top five most important keys to growth for start-ups.
