About Us
Quiteria Belgrane is an online consultancy focused on business model development - helping founders, operators, and teams across Ireland work through the structural decisions that actually determine whether a business holds together.
Where the work actually comes from
A look at how this consultancy operates and what shaped the approach behind it.
The practice started in 2022 from a straightforward observation: most early-stage businesses struggle not because of effort or ambition, but because the underlying model - how value is created, delivered, and captured - was never properly examined. Remote consulting turned out to be a good fit for that kind of structural work. It removes geography as a constraint and keeps sessions focused on the problem rather than the setting.
Sessions are structured around the specific decisions a client is facing, not a standard curriculum. That might mean working through revenue model options, identifying where a current structure leaks value, or pressure-testing assumptions before committing to a direction. The work is analytical and direct - there is no standard playbook applied to every situation, because every business model has different constraints and different leverage points.
The people behind the sessions
Small by design. Every client works directly with an experienced consultant, not a coordinator.
Quiteria works directly with each client on business model decisions - revenue structure, value delivery, and the assumptions that underpin both. Her background spans early-stage ventures and established businesses rethinking how they operate.
Fenella Darch
Fenella supports the analytical side of client work - market sizing, competitor positioning, and the kind of structured research that makes model decisions easier to defend.
Oisín Tarrant
Oisín steps into engagements where the revenue or cost structure needs detailed financial modelling - particularly when clients are preparing for external conversations with investors or lenders.
Bríd Ó Ceallaigh
Bríd focuses on the operational side - how a business model actually gets executed day to day, where delivery breaks down, and what structural changes make the most practical difference.
