On Sunday, I read Learnly's pitch.

Ben had sent it to me on Friday with a note. Flashy founder. Big numbers. Not sure about the product. Your call.

I made a cup of tea and sat at my kitchen table with my laptop.

The slides were very slick. Big promises. The end of homework stress. Every answer, instantly. Teachers optional.

Then I watched the demo video.

A child takes a photo of a fractions problem. The app thinks for a second. Then a video lesson pops up to explain it.

A woman's voice started talking.

“Okay, so here's the trick with fractions. Imagine you've got a pizza…”

I put my tea down.

I knew that voice.

It was mine.

It was a lesson I'd recorded three years ago for BrightPath's free online library. Free for any child to watch, on our website, with our name on it. Our rules said nobody could copy the lessons or use them to make money.

Somebody had cut off the BrightPath logo at the start.

I checked the other lessons in the demo. Seven of them. All BrightPath teachers. All copied from our free library.

Preston Vale was planning to pitch me a company built on my own teachers' work.

Using my own voice.
