Onisis Consulting

We founded Onisis after decades as C-level operators who grew frustrated with how traditional consulting treats leaders. Too many decks, too little empathy – and not enough respect for the instinct that got you here in the first place. We exist for the moments when your gut tells you something is off, but the numbers don’t yet speak clearly. Our role is not to dictate a grand plan. It’s to sit on your side of the table, test your hunches against hard facts, and give you the quiet certainty to move. Four commitments guide every engagement: start with respect, operate with absolute discretion, deliver pragmatic rigor, and always empower the leader. We work behind the scenes so that the credit stays with you. In practice, that means focused C-level financial work around sales performance, cash flow, business intelligence and growth planning – delivered in short, intensive sprints that turn “I have a feeling…” into confident, data-backed decisions.
