The Full Story
About Hummingbird
At Hummingbird Recruitment & Consulting, we're driven by a simple belief: the right people in the right roles can shape a better, more green sustainable future.
Purpose
Founded by Mariken O'Donnell, Hummingbird Recruitment & Consulting began with a clear purpose: to create a recruitment consultancy where values, relationships, and long-term impact matter.
With a background in executive search and education, and a deep personal commitment to environmental responsibility, Mariken saw a gap in the market. Too often, recruitment was transactional, short-sighted, and disconnected from the bigger picture. She envisioned something different: a people-first, purpose-led partner that understands not just who an organisation needs, but why.
What started as a vision quickly became a trusted name in executive search for the sustainability sector. Today, Hummingbird works across a range of industries driving environmental progress, placing leaders who align with mission, culture, and long-term strategy.
We don’t just connect people with positions — we connect purpose with leadership. And we do it with care, curiosity, and an unwavering focus on building a better future.
Journey
Our journey started in the renewable energy sector, working closely with businesses that are powering the transition to net zero. As our network and reputation grew, so did our reach. Today, we support organisations across a wide range of purpose-driven industries, from clean technology and ESG consulting to climate finance and sustainable infrastructure.
Specialist
We specialise in executive search and strategic talent consulting, helping businesses build resilient leadership teams and individuals find roles where they can make meaningful contributions. Our approach is empathetic, tailored, and grounded in a deep understanding of the sectors we serve.
Vision
Hummingbird is more than a recruitment firm. We're a partner in change — committed to the people behind progress. Every relationship we build is rooted in integrity. Every search is guided by a sense of purpose. And every outcome is measured by the impact it creates.
