Yes, a web development agency, though really any profitable business that could use this. Each hour you spend improving/interating/integrating your DIY app is an hour of developer time that you can't bill for. You'd easily spend over an hour per year on a DIY app. Agencies charge at least $120 per hour so the choice between building yourself or paying someone else to do it is a no-brainer. At the enterprise level $500 is the amount employees can generally spend themselves without getting approval, so there should really be a plan at that level of pricing too.
