Ancuta Weiser
Fractional GTM Leader
Who Ancuta works with
Ancuta Weiser is a Fractional GTM Leader for growth-stage, post-acquisition, and PE-backed B2B technology companies generating $50M+ in recurring revenue, working directly with CEOs, CROs, and cross-functional leadership teams. Ancuta is GTM OS Certified, trained in GTM Partners' proven GTM expertise, frameworks, and systems. She serves UK-, Ireland-, and Europe-headquartered businesses, as well as EMEA commercial teams within global technology vendors. Her work focuses on established enterprise software, hybrid cloud, cybersecurity, data platforms, open-source software, developer tools, and technology services companies selling internationally across multiple products, markets, and routes to market.
The GTM problems Ancuta solves
Ancuta resolves reactive renewals and inconsistent account expansion across high-volume commercial and high-value enterprise accounts. She addresses GTM challenges where multi-country growth relies on executive rescue from CROs, founders, and regional leaders rather than repeatable plays. When customer ownership is fragmented across Sales, Customer Success, Delivery, Product, Finance, RevOps, and partners, Ancuta aligns cross-functional teams rather than working in a single silo. Utilizing the GTM Operating System (GTM OS), she establishes clear customer coverage models, fixes poor visibility into renewal risks and installed-base performance, and designs KPI architecture to turn reactive installed-base growth into a predictable commercial system.
Track record
Ancuta brings extensive experience from senior commercial leadership roles at IBM and Red Hat, spanning new business, renewals, expansion, and sales development across commercial, mid-market, and enterprise segments. As the founder of Weiser Advisory, she leads engagements personally, delivering executive alignment, customer-growth operating model design, fractional leadership, and ongoing advisory for established technology businesses.
In Ancuta's words
I’m Ancuta Weiser, founder of Weiser Advisory. I help B2B technology companies with recurring revenue turn reactive installed-base growth into a commercial system they can lead—where renewals, expansion, and forecast confidence no longer depend on executive rescue. I work directly with CEOs, CROs, and cross-functional leadership teams to clarify where growth is breaking, design a stronger operating model, and lead the changes required for more predictable retention, renewal, and expansion.
