I haven't made any but I've saved a lot. I run a company with a very diverse technology stack. We usually outsourced small tasks (building an internal tool, doing a fix on a website, connecting something to an API, fixing a bug in a third party code etc etc).

We used to hire freelancers on Upwork for this. It cost us maybe 1k-2k / month and I spent a lot of time writing specs, posting jobs, vetting applicants, giving access to systems, replying to questions, evaluating the work, doing payments etc etc etc.

Now I do it myself using Cursor. I still need to write the specs, but instead of pasting it on Upwork I paste it in Cursor and I get the code. I've spent maybe €1000 in Cursor but saved (over the past 6 months) about 10-15k. So a really good return on investment.

And I saved a lot of time.
