## **Who we are** Each of us at Yoodli has faced our own communication challenges — overcoming a lisp, freezing during a job interview, feeling anxious about speaking up. That shared empathy shapes a culture that's uplifting, inclusive, and deeply authentic. We value **humility**, a **bias for action**, and the belief that we **win together**. Our team includes former employees from Google, Apple, Microsoft, Tableau, and beyond, united by a problem we've personally lived. We're headquartered in the heart of Seattle, and we're having a lot of fun along the way. Our culture is built on failing fast, iterating constantly, and taking bold bets. We've raised **$60M** — including a $40M Series B led by WestBridge Capital — backed by Madrona, Neotribe, Cercano, and incubated at the Allen Institute for AI. We're valued at $300M and grew revenue 900% year-over-year. Our customers include Google Cloud, Snowflake, Databricks, RingCentral, SAP, FranklinCovey, KornFerry, Sandler Training, Toastmasters, and many more — with learners in over 150 countries.
