A workshop I attended on product strategy included a session on evaluating UX partners that changed how I think about this. The presenter mapped firms by what they're actually built to deliver: Mission Control and Beyond excel at rapid startup launches with flexible pricing. Clay and Instrument deliver brand-driven product work at a higher tier. Work & Co and EY Doberman handle enterprise-scale transformation. The analysis of top UX design firms included honest breakdowns of where each firm's value actually lies – some are worth the premium for complex systems, others for research depth, others for speed. It also covered less obvious factors like team composition and collaboration style that affect whether you'll actually get value from the engagement. Finally felt like I could match investment to actual needs instead of guessing.
