Heather Barnett brings 15+ years of enterprise security, cloud GTM, and AI leadership — with the operational discipline of a Chief of Staff and the execution instincts of a senior operator — to companies that need executive-level impact without the cost or timeline of a full-time hire.
I step in where the need is real — as a senior operator who executes alongside your team, not a consultant who hands off a deck.
Operating cadence, cross-functional alignment, OKR governance, and executive decision support — the connective tissue between strategy and execution.

Specialty. Microsoft partner motion (co-sell, MISA, marketplace, GBB/STU engagement) for cyber and cloud-adjacent companies.

I'm Heather Barnett, founder of H. Barnett Group. I spent a decade at Microsoft across security field sales, global customer success partner strategy, and Chief of Staff in Commercial Cloud (Fraud, Security & Risk) — before founding this practice to bring that same caliber of execution to growth-stage and enterprise companies on a fractional basis.
My background spans enterprise security, cloud GTM, AI adoption, and executive operations. I've governed $125M+ portfolios, driven 150% quota on $100M+ in annual security revenue, and led 30+ AI initiatives across large organizations.
I work with a small number of clients at a time — by design. You get real access, not a staffed engagement.
Heather is the best leader I've had. The org would not have been as wildly successful without her.
You truly are an essential leader in the growth and maturation of our discipline — strategically and tactically.
You don't just create clarity in the moment — you build momentum and sustained alignment that moves the organization forward.
I take on a small number of engagements at a time. If the timing and fit are right, I'd like to hear from you. Email is fastest. Calendly is best for a real conversation.
