I've had 2 (so far)

I was part of a team which built a very early telehealth platform. A bunch of the work was open-sourced as rtc.io (though I didn't have much to do with that). The resulting company and tech is used by a few million people a month (I think).

I built an ML system used at a large drop-ship retailer which ingested huge excel spreadsheets of products from suppliers and added them to the retailers database in a consistent manner. This made a painstaking and horrible job for 12 people into a job that was done by 2 people 2 hours per week. Yes, we replaced people in their jobs, and I hope they all went on to get better jobs, because everyone hated that job, and most people only lasted a few months.

I also was founder of Ayvri (3d mapping sports tech for paragliders) - I don't put this in the same category as the others, though it was the most lucrative for me, because though paragliders loved it, as did a few ultramarathoners, etc. I don't think it really had the level of impact.

For the last 4 years the team I worked with in telehealth have returned to our health roots and are working on improving sleep with affectablesleep.com

I used to paraglide, and I remember it as Doarama. It was quite used by paragliders, especially in some videos. Personally I liked it in the beginning, but people started to abuse it, and sometimes the videos would consist mostly on the doarama scene (with a voice over). I would skip those parts of the video, or close the video after some time. It wasn't the same as watching a real video capture from the terrain, which I did prefer..
