San Francisco, CA22y exp

“Operator/strategy leader with experience driving digital transformation and building executive operating systems in high-noise environments. At a legacy B2C brand, created a prioritization framework and exec alignment process that cut 100+ initiatives to 16 and lifted execution from 12% to 81%. At Point B, owned a $20M delivery budget while shifting the firm to a tech-forward practice, implementing OKR/KPI cadences and AI-enabled workflows (n8n, LLMs, gamma.ai) that materially improved executive productivity.”

“GTM/Revenue Operations-style leader who rebuilt a company’s go-to-market motion at IFS Loops while running cross-functional execution across Sales, CS, Product, and Marketing. Implemented an executive operating system (cadences, Notion dashboards, decision logs, briefing packets) that cut urgent escalations ~40% and freed 20–30% of CEO/CRO time, while delivering a pricing launch that drove >10% ACV uplift and improved activation/retention.”

“Finance and operations executive who rose from FP&A into VP Operations, Chief of Staff, and CFO roles across Fortune 500, startups, advisory, and a boutique law firm. Particularly strong at high-stakes transformation work—sell-side diligence, carve-outs, executive alignment, and revenue-operations redesign—especially in subscription and high-growth environments where financial insight must quickly translate into organizational action.”

“Operations leader/Chief of Staff profile with experience building organizations in both government and high-growth tech. Helped stand up Senator John Fetterman’s Senate office—designing the org structure and systems for a 55-person team—and later improved planning, reporting, and OKR execution within Stripe’s legal/global policy org during rapid scaling. Now consults part-time to help executives translate strategy into execution through clear ownership, operating rhythms, and scalable systems.”

“Transformation and integration leader with experience spanning Morgan Stanley, Exiger, and Cisco, focused on helping organizations execute through acquisitions, large-scale change, and operational complexity. Particularly compelling is their blend of enterprise M&A integration expertise and practical AI modernization work, including leading a RAG/LLM-based diligence initiative across 13 functional domains.”

“Startup operator and chief-of-staff-style strategic ops leader who has repeatedly built executive and delivery infrastructure from scratch in fast-moving, founder-led environments. Most notably, they created lightweight operating systems at The Suite and scaled Chief’s facilitator network from 0 to 500+ in six months while increasing capacity 150% and improving CSAT/NPS.”
