## CodeFast

CodeFast is a coding course written for entrepreneurs rather than job seekers. Its argument is that traditional courses are designed to prepare engineers for interviews — inverting binary trees, memorizing Big O notation, reading documentation longer than a novel — while a founder only needs the slice of web development required to build and launch an idea. The curriculum strips out that surplus and concentrates on what you will actually use when shipping a product.

The course runs about twelve hours of video across a fourteen-day structure. Day one is mindset and fundamentals: how to ship fast, how to make money with code, and the basics of HTTP, domains, HTML, CSS and JavaScript, framed so that you can tell an AI what to build. From there it builds a real SaaS — Next.js and React components, Tailwind CSS for design, MongoDB with API routes, magic link and Google OAuth authentication, a private user dashboard, Stripe and LemonSqueezy subscription payments, emails, custom domains and hosting, with Git and deployment covered along the way.

A distinct part of the pitch is how it frames AI. The course assumes 2026-era tooling where AI can explain code, fix bugs and write sections of your app, and its position is that this makes fundamentals more valuable rather than less: you cannot direct or debug an AI reliably if you do not understand what it is doing. Lessons on AI-powered coding and design sit alongside more conventional business material such as copywriting essentials and SEO. The course counts 4,483 enrolled entrepreneurs and is published by Marc Lou, who has built 25 small products and earned over $200,000 from SaaS.

**Pricing & Plans:** One-time paid course rather than a subscription. Enrollment grants instant lifetime access to the roughly twelve hours of video, with periodic promotional discounts such as the Thanksgiving sale advertised at 43% off. There is also an affiliate program paying up to $150 per referral. Exact pricing is shown on the site's pricing page.

- **Short, entrepreneur-focused curriculum:** 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.
- **A real SaaS built step by step:** Rather than theory for interviews, you progressively build a real authenticated, paying SaaS, which is the actual deliverable of the course.
- **AI as a force multiplier:** 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.
- **Business skills alongside code:** 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.
- **Taught by a practicing indie maker:** The course is taught by an indie maker who has shipped 25 small products and earned over $200,000 from SaaS, with case studies from students who launched their own apps.

**Strengths:** Roughly twelve hours of video instead of the 60-plus hours a typical JavaScript course requires; Builds an actual authenticated, subscription-based SaaS rather than toy exercises; Covers business essentials — payments, domains, SEO, copywriting — not just syntax; Explicitly written for complete beginners with no prior experience

## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies
