I'm Hillary, founder of Reilly & Co., a fractional HR practice built specifically for tech companies.
15 years in People Operations taught me something most People functions get backwards: the goal isn't more process, it's the right process at the right stage. A 15-person startup and a 200-person scale-up don't need the same People function. Instead, they need someone who knows which problems to solve now and which to intentionally defer.
Before founding Reilly & Co., I led People at WordStream, Validity, Inc, Yalo, and Equitybee as a full-time Global Head of People. Since founding Reilly and Co., I’ve worked fractionally with several tech companies, where I built tech stacks, comp frameworks, ran org design through hypergrowth, set talent strategy, stood up compliance infrastructure, and more. I've sat in the room for the decisions that actually matter: who to hire, how to pay them fairly, when to restructure, and how to build a culture that survives scale.
I work remotely and travel to client sites as needed which means you get senior-level attention without the overhead of a full-time office hire. I am US based, but am available globally.

Strategic first, tactical always. I won't hand you a slide deck and disappear. Every engagement produces something your team can actually run with: policies, frameworks, systems built to hold up as you grow.

No jargon, no padding. You're paying for judgment, not vocabulary. I'll tell you what I'd do as if it were my company.
