There are many things which benefit from being digital, which aren't digitized enough. Usually this means third parties are making a lot of money by offering a platform until digitization happens.
If you sell any product or service to the public, these are generally the steps you go through to benefit from digitization:
1. No digital presence at all.
2. Digital presence through a third party which takes a 15%-25% cut of sales.
3. Digital presence through a SaaS which has a monthly fee.
4. Digital presence which you own yourself.
Step 3 and 4 are still very underserved markets, where customers could make massive savings or sales increase. And those who offer these solutions will profit.
