I'm Hillary, founder of Reilly & Co., a fractional HR practice built specifically for tech companies.
15 years leading People Operations in startups 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 scaled company 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've built tech stacks, compensation frameworks, led org design through hyper growth, 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.
