Before HustlBase, I spent years as a PLM consultant — deep in PTC Windchill, the kind of enterprise-software niche you don't stumble into by accident. It taught me the most underrated truth in consulting: the narrower and more "boring" your specialty, the less competition you face and the more clients will pay for it. Windchill and PLM, SAP, NetSuite, Salesforce admin — these unglamorous platform niches are some of the highest-leverage consulting plays on this board. If you already carry a corporate skill like one of these, don't bury it on your résumé. Lead with it.
