About RevenueOS

Experienced operators. Three practices. One operating system for growth.

RevenueOS Ltd is a boutique business consultancy delivering operating system engagements across Ireland, the UK and EMEA. We take on a small number of deep engagements, and only work with businesses where we believe we can have a genuine impact.

Why we built this

Most growth problems are not growth problems. They are operating system problems.

The pipeline meeting that fills the diary but doesn't move the number. The CRM that the team works around rather than through. The AI pilot that never makes it into production. The leadership team that runs the business through heroics and key-person knowledge. None of these are software problems. They are system problems — and they compound.

Twenty-five years inside the world's leading technology platforms — Salesforce, ClickUp, HubSpot — taught us how the best operators design their commercial engines. Repeatable. Inspectable. Independent of any one person. The same playbook used by US-headquartered multinationals to scale from one region to many.

European founders rarely get access to that playbook. They build remarkable companies, then hit a ceiling that has nothing to do with their product or their market — it's their operating model. RevenueOS was built to close that gap. We bring the operating discipline of the world's best commercial platforms to ambitious European leadership teams, and help them install the systems that make growth predictable enough to win in international markets.

AI makes this moment unique. We are living through the largest reorganisation of work in a generation. The companies that will win are not the ones with the most AI tools — they are the ones with the operating system clear enough for AI to plug into. RevenueOS is built for that moment.

The bench

Operators first. Consultants second. Always outcome focussed.

Each lead consultant brings 20+ years inside the world's leading technology platforms. We've taken those lessons and built RevenueOS to help build the next generation of businesses.
