Dear GTM Strategist,

AI didn’t just change how we create - it’s changing how we learn.

Few teams understood this as early, or as deeply, as Kei and Kazuki, the founders of Glasp.

From a hospital bed in Japan to 3.5M users worldwide, their story is a masterclass in what organic growth means in the age of AI:

  • Building for curiosity, not just clicks.

  • Letting small experiments go viral.

  • Turning human knowledge into something that lasts.

From building one of the first ChatGPT-based Chrome extensions to figuring out AI search (AEO) - everything based on a sound business strategy and understanding users’ needs.

That’s why I invited them to present their case in this week’s GTM Strategist newsletter.
