The narrator welcomes students to a course on creating profitable Chrome extensions. He encourages students to aim for releasing their first extension within 30 days. The narrator shares examples of successful Chrome extensions developed by solo developers.

The narrator's own extensions, Merch Wizard and KDP Wizard, were built while working a full-time job. These extensions eventually allowed him to quit his job and later exit for multi-six figures. Other successful solo-developed extensions include PrettyMerch, Canva Automation, and tools for Poshmark Automation and job hunting.

Jungle Scout, an Amazon product research tool, was started by one person and now employs over 200 people globally. The founder traveled the world while building the extension, which now generates multi-millions in annual income. Grammarly and Honey are also mentioned as successful extensions, with Honey selling for $4 billion.

The narrator emphasizes that students don't need to aim for billion-dollar exits. The course provides step-by-step guidance for building a first profitable Chrome extension. The next lesson will cover a high-level program overview.
