Why would SMEs need a bookmarking tool ?

Hello, this is my first time posting here, excited to be part of the community.

A few months ago I built an online bookmarking web app for my personal use since I didn't really like the available solutions out there. The app is quite basic and lacks a lot of design and UI improvements since I was the only one using it.

I showed the app to a couple of friends and they really liked it and started using it straight away but after a couple of weeks they stopped. They really didn't give me any useful feedback other than we really don't use bookmarks that much which I respect which means that they are probably not my target audience.

Anyways I was reading a lot and from what I understood is that B2B SaaS model is theoretically the best model out there these days for a micro SaaS and I started wondering how can an online bookmarking tool solve a problem for any business.

I thought I'd post my question here so that I can start a discussion and brain storm a little bit with any one who finds this idea interesting. So here is the question : Can you think of any use cases where a small online business find a good use case for an online bookmarking tool ?

Thank you
