Luis von Ahn and Severin Hacker founded the company in Pittsburgh in 2011, and von Ahn had previously invented CAPTCHA and reCAPTCHA. The app teaches languages through short gamified lessons, with streaks, leaderboards, and notifications engineered for daily habit rather than depth. Most users learn free with advertising while a subscription tier removes ads and adds features, and the English proficiency test sells to universities. Generative AI features arrived through Duolingo Max. The owl mascot became an unusual social media presence.

Equity comp at Duolingo
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

If a meaningful share of your net worth sits in DUOL, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with DUOL's option-implied volatility.

Duolingo equity questions
- How much DUOL stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your DUOL position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Duolingo grant ISOs, NSOs, or RSUs?
- Equity compensation at Duolingo typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Duolingo RSUs use double-trigger vesting?
- No. Duolingo restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
