Let me show you something that genuinely surprised me when I first saw it.
Udemy has over 70 million students.
Not 70,000. Not 700,000. Seventy. Million.
And that's one platform.
There's also Skillshare, Teachable, Thinkific, Kajabi, Coursera, and a dozen others — plus the option to sell directly.
Here's why that number matters for you:
Even the most niche topic you can imagine — let's say "watercolour painting for left-handed adults over 50" — represents tens of thousands of potential students on a platform that size.
You don't need everyone. You need enough.
A course that sells to 200 students a year at £20 each is £4,000. Passive. Recurring. From something you made once.
For most people reading this, that's not a business — it's a bonus. A side income that rewards knowledge you already have.
The question was never whether anyone would buy it.
The question is: are you going to make it available for them to find?
What's the niche you think is "too small"?
