The execution infrastructure isn't built to match them yet.
Initiatives aren't landing at the pace investors expect.
But the organization doesn't know how to operationalize it at scale.
Executive operations, OKR design, cross-functional alignment, board and investor materials, and organizational effectiveness.
Go-to-market architecture, revenue operations, partner strategy, field readiness, and pipeline governance.
Enterprise AI strategy, copilot and agentic workflow deployment, initiative governance, vendor evaluation, and change management.
Enterprise security posture, cloud strategy, Microsoft ecosystem, and ISV/partner ecosystem guidance.
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 (Security, Fraud and 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.

If the timing and fit are right, I'd like to hear from you.
