I want you to think of computers, how you buy upgrades to a game, new upgrades to your computer. Things that make it perform much better.
Now think of a service you can plug into a business. A service that once plugged in will upgrade the overall system.
Some ideas bouncing around:
Retail Sales Training – plug this technology into your retail chain and watch your average revenue per customer rise.
A catering company that provides healthy food in the workplace, watch overall health & wellbeing increase (maybe less staff downtime / sick leave).
Financial management (often a place it actually does exist).
