At what point did the spreadsheet stop working?

Every CRM I look at is priced for a team of ten. I'm not a team of ten. Most of the founders I talk to aren't either, and almost all of them are running their whole pipeline in a spreadsheet and quietly embarrassed about it.

I don't think they should be. A spreadsheet is fast, free and does exactly what you tell it. It just breaks at some point, and I'm trying to work out where that point is.

For the people who moved off it: what actually forced you? Was it the number of deals, forgetting a follow-up, a second person joining, or something else entirely?
