Be careful with "lack of competition". You are ALWAYS competing with the incumbent solution. No matter how clumsy or awkward it seems; no matter how much better it could be; those solutions have amazing staying power and your niche can become your enemy because there's a limit universe of customers to sell the solution to.
In the industrial space, no one ever got fired for buying Rockwell Automation.
Even if FactoryTalk is absolutely horrid.
The upside is a lack of competition and a B2B environment. No need for a marketing department when you just have to attend a few industry trade shows a year.
