In September 2021, I started selling a LinkedIn guide on Gumroad.
There was one small problem.
I had not written it.
What I had was a collection of notes. Things I had written down while trying to understand why some LinkedIn posts worked, why others disappeared, how I was growing my network and how any of this could eventually become a business.
The notes were useful to me. That did not make them a guide.
Still, I announced it.
I put the product on Gumroad for $5 and presold copies in the double digits. I no longer remember the exact number, which is probably evidence that I was not operating a particularly sophisticated publishing company at the time.
But enough people paid that I now had a deadline and a problem of my own making.
I gave myself 30 days.
The guide became 100 Simple Steps to Build Your Personal Brand on LinkedIn.
The price moved from $5 to $9 and eventually $19. I sent it to the people who had trusted me before it existed, then continued selling it through Gumroad.
That was how I started using the platform.
Not because I had designed a funnel.
Because I needed somewhere to collect five dollars for an unfinished PDF.
What I thought I was selling
I treated every purchase as a small digital-product sale.
Someone paid $5, $9 or $19. I sent them the guide. Transaction complete.
I did not have a serious follow-up sequence. I did not classify buyers. I did not move them into a CRM. I did not ask what problem had made them buy or what they wanted to do next.
In other words, I had built the front door and forgotten that there was supposed to be a building behind it.
Then something unexpected happened.
People who bought the guide began following my work more closely. Some were already following me and now had a reason to take me more seriously. They read the guide, saw how I thought and contacted me.
One was an executive from a Fortune 500 company who later approached me about ghostwriting.
There were other conversations and larger opportunities I cannot describe because of NDAs.
The important part is not the names. It is the change in the relationship.
Before the purchase, I was someone posting about LinkedIn.
After the purchase, I was someone whose process they had paid to inspect.
What happened next is why this issue is not really about selling PDFs.
It is about using Gumroad to identify interest, earn trust and create demand for something considerably more valuable than the product itself.
I discovered that accidentally in 2021.
Here is how I would build it deliberately today.
