Mauro Donadio is the founder and principal consultant of Bermola Consulting, a senior-led digital consultancy based in London. He founded Bermola in 2015 with a clear conviction: that established businesses deserve senior expertise on every engagement, not just at the pitch.
Through Bermola, Mauro has spent his career leading significant technology programmes at some of the UK's largest and most complex organisations. His work spans digital transformation, legacy modernisation, cloud migration, and enterprise software engineering. He operates at the most senior levels, working directly with CEOs, COOs and boards, and remains personally involved from strategy through to delivery.
His approach is grounded in diagnosis before prescription: every engagement begins with a clear, honest assessment of the current state, so that the strategy is built on reality rather than assumptions. He has applied this across financial services, retail, food and beverage, travel, healthcare, and media, working with organisations ranging from FTSE 100 companies to high-growth scale-ups.
