To chime in as another TriNet "user" (e.g., employee of a startup that used them), they're pretty great on both ends. They handle a lot of regulatory and benefit management for the employer (state/local taxes, 401(k) programs, health benefits), and for the employee, TriNet's HR dashboard feels modern and easy to use. When my current company was abruptly forced to switch from "independent subsidiary of BigCo" to "division within BigCo", we had to switch from TriNet to all of BigCo's internal HR systems -- most of which are clearly powered by HR IT companies like Workday and UltiPro -- and they are all just terrible. Uh, anyway, yes, PEOs seem like good ideas. :)
