About 

I am Ancuța Weiser, Founder and Principal at Weiser. Advisory. 

I help leadership teams in B2B technology companies connect strategy to execution, clarify ownership, and make customer growth more predictable.

Experience at a glance

I have spent more than 20 years leading revenue teams across the full customer-growth system. That includes senior leadership at IBM and Red Hat across new business, renewals, expansion and sales development.

I have worked across subscription, SaaS, annuity and on-premise licensing models, with more than $500M in annual contract value across multi-product portfolios, languages, countries and routes to market—including direct sales, embedded partners and resellers.

As Head of Digital Sales for the United Kingdom & Ireland, I led sales across infrastructure, software, cloud and technology lifecycle services, working across both inbound and outbound motions and a $200M+ regional P&L.

I also built a global, outbound-only Sales Development organisation from zero to a $20M+ qualified-pipeline engine for new-logo growth.

Why this experience this matters

Customer growth does not happen inside one function

Customer growth is shaped by the offer, route to market, time-to-value, coverage model, renewal motion, expansion path, data, and leadership cadence.

Different environments have taught me the same lesson: customer growth becomes more predictable when leadership can see the system clearly, customer value has an owner, and teams have a rhythm for acting before risk becomes rescue.

Practical leadership, not abstract strategy

I started as a linguist and teacher before moving into technology. I did not enter the industry with an inherited technology playbook, so I learned to work by listening carefully, recognising patterns, and building clarity where the path was not yet defined.

That experience still shapes how I work today. I am comfortable in complex environments where the answer is not obvious, the operating model is evolving, and the business needs both strategic perspective and practical leadership.

I work in English, German, and Romanian, with conversational French.

A shared framework, not a standard playbook

As a GTM OS™ Certified Partner, I use the proven framework as a shared diagnostic and operating language. It gives structure without assuming every business, segment or route to market should work the same way.

My belief

Growth should not depend on heroics. Growth should be built into how your teams work.

That belief sits behind the way I help leadership teams connect strategy to execution, clarify ownership and make customer growth more predictable.
