About Penta (formerly Hume Brophy)

Brussels Office Since

2005

Firm Description

At Penta, we have reimagined communications, reputation management, and brand-building for times of turbulence. Political populism, digitisation and AI, cultural breaks and geopolitical turmoil are the new way of things. We are your indispensable guide to this uncertain world. And we bring you uncommon new tools to our work.

Our work begins and ends in data. We illustrate what your stakeholders are seeing, thinking, and doing, and help you respond and plan. Our data-driven view on the forces at work helps you act fast. We anticipate trends and help you see what’s coming down the path or round the corner. Stakeholder tensions mean trouble: we guide you to a full view of audiences. We tell you things you don’t know about yourself, break down silos, uncovering secrets about constituencies.

Uniquely, we help you understand every individual stakeholder in detail and as components of an integrated, deliberate corporate engagement strategy.
