eli5: How can Google maps know many small and recent businesses’ locations so accurately?

Question

I’ve realised that most businesses (even small kiosks) are seen on Google maps. Where and how do they get that information?

Feel free to edit hours of businesses if you ever see they’re wrong! Anyone can make edit suggestions that then get reviewed.

I once moved a google location after a job interview because the location sent me to the wrong place and no one knew how to fix it in the building.
