Our work sits at the intersection of people, strategy, governance, and culture, focusing on enhancing organizational effectiveness. We assist organizations in transitioning from ideas and intentions to clear decisions, practical plans, and measurable actions. Every organization is unique, so we invest time in understanding its people, history, operating environment, and goals before recommending a pathway forward. Our human resources consulting is grounded in evidence, informed by experience, and designed to thrive in the real world.


Billi is helmed by Olivia Mensah, an executive advisor, HR leader, and facilitator with extensive experience in helping boards, leaders, and organizations navigate change.

The ram’s horn featured in the Billi logo is inspired by the Adinkra symbol Dwennimmen, which represents strength and humility. This reflects our belief that effective leadership requires both the strength to make difficult decisions and the humility to listen, learn, and lead with authenticity.
