Learn just enough code to launch a real online business in 14 days
Fundamentals, a full SaaS build, and the business side — payments, domains, hosting, SEO — are covered in about twelve hours of video instead of the dozens of hours a conventional JavaScript course spends on topics you will never use.
Rather than theory for interviews, you progressively build a real authenticated, paying SaaS, which is the actual deliverable of the course.
Sections on AI-powered coding and design show how to use AI to explain code, fix bugs and generate parts of your app, framed as leverage on top of fundamentals.
The syllabus includes the non-coding skills that decide whether an app makes money: copywriting essentials, payments with Stripe and LemonSqueezy, domain and DNS setup, hosting and SEO.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
