The full story

TL;DR

Wes Bos started teaching at a coding bootcamp, then launched "React for Beginners" — 2,300 students in 3 weeks. His free JavaScript30 challenge attracted 754K+ sign-ups. Total: $10M+ in course revenue from Hamilton, Ontario.

Wes Bos has been building websites for over 25 years, starting as a self-taught web developer in Hamilton, Ontario, Canada. His teaching career began at Ladies Learning Code, a Canadian nonprofit, before progressing to full-time instruction at HackerYou (now Juno College of Technology).

React for Beginners: The Breakout

In November 2015, Wes took a leap and launched "React for Beginners," his second premium product after The Sublime Text Book (October 2014). It was an immediate hit: 2,300 developers enrolled in the first three weeks. The course filled a gap: React was exploding in popularity, but learning resources were scattered and incomplete.

The model was perfectly suited to the fast-moving JavaScript ecosystem: deep-dive into a technology, build a comprehensive course, then re-record it when the technology updates (React for Beginners has been re-recorded multiple times).

Stacking Courses

Wes stacked course after course over the next few years: ES6 for Everyone, Learn Node, Advanced React & GraphQL, Beginner JavaScript, Master Gatsby. Each course addressed a specific pain point in the JavaScript ecosystem.

JavaScript30: The 754K-Student Funnel

In December 2016, after his first $100K ARR milestone, Wes created JavaScript30, a free 30-day JavaScript coding challenge. It became one of the most popular free coding courses on the internet, attracting 754,180 sign-ups as of August 2026. This created a massive email list that scaled paid course purchases afterward, rather than driving that first milestone.

Syntax.fm: The Podcast

In 2017, Wes co-launched the Syntax.fm podcast with Scott Tolinski. It became one of the top web development podcasts globally, providing ongoing visibility and trust that compounded course sales year after year.

Career revenue: $10M+ from courses
Paid students: 55,000+ (36,322 for React for Beginners alone)
Free students: 754,180 (JavaScript30, per javascript30.com, August 2026)
Total reach: 500,000+ developers taught
Podcast: Syntax.fm (top web dev podcast, co-hosted with Scott Tolinski)
Location: Hamilton, Ontario, Canada (sole proprietorship)

Key Takeaways

Free courses are the best lead magnet — JavaScript30's 754K sign-ups created a massive funnel for paid courses

Re-record and update courses as technology evolves — this keeps content relevant and enables repeat purchases

Podcasts create ongoing visibility and trust that compounds for years — Syntax.fm is a permanent marketing engine

How Wes actually did it

7/7 funnel stages sourced

Reconstructed from Wes's own published sources. Quoted claims are the founder's words, verified verbatim; anything marked as our analysis is exactly that.

Where the idea came from

Audience request

Wes's info-product business started with the Sublime Text Power User Book (Oct 2014), which he wrote after readers of his free blog tips kept asking for more depth than short posts could give. That book, not React For Beginners, was his first paid product; React For Beginners followed a year later as his second.

“The idea for this book was spurred on after a few blog posts on Sublime Text — my readers loved the tips and were always asking for more!”

Validation

Built first, validated after

OtherValidated

Free Sublime Text blog posts acted as the topic test. Wes published tips, watched which ones readers responded to, and only then committed to the paid book on the topic that kept generating requests.

Wes did not run a formal test before the Sublime Text Power User Book. The demand signal came from the free blog posts he had already published: readers kept asking for more depth than a short post could give, and that is what turned the topic into a paid product.

“my readers loved the tips and were always asking for more”

Sublime Text Power User Book - now available! (wesbos.com)

OtherValidated5000 manual customers

Course topics after the first product were picked from what existing students asked for next. Learn Redux was built as the direct answer to the question React For Beginners buyers kept sending him.

By 2016 Wes had a paying student base to read demand from. He framed Learn Redux as the answer to the question over 5,000 React For Beginners students were already asking him, so the topic was chosen from stated customer demand rather than guessed.

“I've had over 5,000 people take my React For Beginners and this is the answer to "What should I learn next?!"”

Announcing Learn Redux (wesbos.com)

No validationInconclusive

No presale, waitlist or landing page test preceded the first paid product. Wes wrote and re-wrote the book for a year and a half before anyone could buy it.

The first product was built in full before it was ever offered for sale. Wes spent about 18 months writing and re-writing it, with no presale or paid pre-order step in between.

“It was really hard to write - took me 1.5 years, tons of research and re-writing.”

First test users

Existing audience~2300 usersPaying from day one

Wes drew his first React For Beginners students from the audience he had already built through his free Flexbox.io and Command Line Power User courses and his blog readership; over 2,300 developers had joined within the first three weeks.

“many who have taken the free Flexbox.io and CommandLinePowerUser.com courses are now learning react”

Existing audiencePaywall from launch

React For Beginners launched directly as a paid, premium course with no free tier, sold straight into the audience Wes had already built with his free courses and blog.

“I'm super excited to announce React For Beginners - my new premium step-by-step training course”

Acquisition channels, and whether they worked

Word of mouth · Community reputation built via years of free blog posts and free coursesPre-launchWorked

Years of free blog posts and free video courses established Wes as a known, trusted name in the developer community before he sold anything.

“the biggest one is that I'm somewhat of an expert in the community - I have lots of free blog posts and videos so I've gained trust there”

Wes Bos (wesbos) comments on his own Sublime Text Book launch thread, Hacker News

Buyers already trusted him from free content, so the paid book/course was a low-risk next step rather than a cold pitch.

“I have lots of free blog posts and videos so I've gained trust there”

Twitter / X · JavaScript30 free 30-day challenge as lead magnet, announced on Twitter and by emailScalingWorked

JavaScript30 launched as a free 30-day coding challenge, announced through Twitter and an email to Wes's existing list, and signed up over 45,000 people in its first week.

“You have probably heard on Twitter or got an email from me. I just launched JavaScript30 - my latest free course. It has absolutely blown up - over 45,000 people have signed up in less than a week”

Other · Syntax.fm podcast, co-hosted with Scott TolinskiScalingWorked

Wes co-launched a weekly web development podcast with Scott Tolinski, introducing himself on the trailer episode as a course creator, tying the show directly to his course business from day one.

“I am a full stack developer from Canada. And I essentially create training courses that help web developers get better at their job.”

What didn't work

ChannelScalingCost: money

Paid Facebook ads did not work for Wes. He and Scott listed his Facebook ads among his own failures when they devoted a whole Syntax episode to failure in December 2017.

“Wes' Facebook Ads Failures”

Failure, Syntax #22 show notes, published by Wes Bos and Scott Tolinski on their own podcast site

What they did instead: Kept leaning on free content, the email list and word of mouth, which he has repeatedly named as what actually sells his courses

OpsScalingCost: money

Paying MailChimp to hold his email list stopped making sense as the list grew. Wes was spending roughly $2,500 a year, about $200 a month, on a list he emailed only when he had a course to announce.

“Since I don't send out a regular or weekly email, I was pretty much paying $200+ a month to hold onto email addresses.”

From MailChimp to Sendy - how I saved $2,400/year on my email list (wesbos.com)

What they did instead: Moved the list to self-hosted Sendy on top of Amazon SES: a one-time $65 licence plus about $1 per 10,000 emails sent

OpsPre-launchCost: money

Hiring the cheapest possible accountant in his first year of self-employment backfired. This predates the courses, in the web consulting years of the same sole proprietorship that later sold them, and it is the mistake Wes puts first when he writes about running the business.

“My first year I paid someone $50 to do my taxes and I really got what I paid for. I had my taxes reassessed three times”

Everything I wish I knew running a sole proprietorship business (wesbos.com)

What they did instead: Paid about $700 the following year for a proper accountant, which he says straightened the filings out and saved money over the long run

How it changed as they grew

Today: 1 person (Solo operator across every founder-published source checked)

Bootstrapped

What broke as they grew

Keeping flagship courses current in a fast-moving front-end ecosystem forces Wes to periodically re-record them from scratch; React For Beginners alone has been fully re-recorded three times since its 2015 launch.

“The front end development landscape sure does change quickly and this is the third time I've re-recorded it to keep the course up-to-date with the latest in API changes and industry best practices.”
