Doing something similar. Bought a business in the petroleum equipment service space. Building internal tools for ourselves. Pen and paper still dominates the industry.
Would you recommend buying a business over starting one from scratch when possible?
In general, there are a lot of serious rules around energy and fuel industries. Rockwell and Kongsberg technology still dominate for some very practical reasons. Seeing a few small firms fail hard in the area, I would still call it a fools errand for those looking at low hanging fruit. =3
