For six years I worked in a SaaS startup that built an applicant tracking system (a tool to manage recruitment efforts in big/mid-sized companies) tailored for the local market of the country we lived in. My experience tells me that our main value was in forcing them to rethink their recruitment processes, not adapting to their existing ones that were usually all over the place.

As much as I want to believe the opposite to be true as a “power user”, good tools often force you to adopt better practices, not the other way around.
