There's an obscene amount of software used in the enterprise that is an absolute pain to use, and inefficent too. Basically nobody in their right mind would use this stuff if they weren't being paid to do so - and if someone created a nicer alternative, the people using it would lobby their bosses to switch. Basically, the design/usability/UX revolution that has happened in the consumer IT space in the past decade has not made nearly as much of an impact in business software (especially when it comes to software aimed at non-IT companies). Companies like Slack have shown that you can make SaaS go almost viral if you address a real pain point in a way that the people on the ground understand and like.
