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.
Qualitative research depth at survey scale, moderated by AI
Run hundreds of concurrent interviews in any language by video, voice or text, with a moderator that probes dynamically based on audio and visual cues.
Generate an interview guide from your research goals, mixing qualitative and quantitative questions with advanced probing and intelligent skip logic.
Recruit from a pool spanning 85+ countries without timezone or language friction, or share an interview link with your own list.
Access bespoke simulated audiences grounded in real humans, for always-on long-form interviews or chat, with confidence scores and source traceability.
