I bet you haven't heard of Luis von Ahn. But I can almost guarantee you've used one of his inventions.

2000: Luis co-creates CAPTCHA to help companies thwart cockroaches of the internet (read: bots).

Today, 200,000,000 CAPTCHAs are typed daily...

2007: Luis fears his original creation is wasting millions of hours of human brain power, so he invents reCAPTCHA.

The idea is simple, but kinda brilliant: users must type out a word, which proves they're not a bot. But in doing so, they are helping to digitize a century-worth of old newspapers & books.

In 2009, Google acquires reCAPTCHA for $10-100 million.

But wait, there's more.

2011: Luis co-founds Duolingo(!) as part of his mission to enable people of all social classes to access opportunities through learning.

Duolingo IPOs in 2021. Today, it's a ~$10 billion company with 88.4 million monthly active users.

LvA is an absolute G.

Whether it's the popular language learning app @Duolingo, or entering a CAPTCHA code, chances are you've used some of the technology Luis von Ahn has created.

@EmilieIkedaNBC spoke with @LuisvonAhn about earning a spot in the National Inventors Hall of Fame and his backstory.
