What I learned buying 4 online businesses

I've bought four online businesses. I made mistakes on all of them.

Here's what I learned.

Acquisition #1: I bought the revenue, not the business

The first one looked great on paper. $500K ARR, growing, good margins. What I didn't see: the entire business was built on a single Google Ads channel that the founder managed personally. Six weeks after acquisition, the algorithm changed and revenue dropped 40%.

Acquisition #2: I underestimated the technical debt

The second business had a decade of code that nobody understood. Every "quick fix" took three days. Every feature request required spelunking through undocumented spaghetti. The revenue was real. The cost of operating it was invisible.

Acquisition #3: I overpaid for the founder's relationships

The third business was built on the founder's personal network. Clients loved him. They didn't care about the company. When he left, half the clients left too.

Acquisition #4: I got it right

By the fourth acquisition, I knew what to look for:

• **Systems over people** — Does the business work without the founder?
• **Clean code** — Can a new developer understand it in a week?
• **Diversified channels** — Can one algorithm change kill the business?
• **Documented processes** — Is there a playbook, or is it all in someone's head?

The lesson

Buy the business that works without its founder. Everything else is a job, not an asset.
