About us
We believe every organisation can go further than it thinks.
Our story
99PlusOne was founded on a simple observation: most organisations stop at 99%. They have the talent, the product, and the ambition — but something keeps them from that final push to breakthrough.
We exist to be that +1. The clarity, the strategy, and the operational rigour that turns good companies into exceptional ones. Our partners range from venture-backed startups to Fortune 500 enterprises, across sectors as diverse as fintech, healthcare, and sustainable energy.
What unites them is ambition. What unites us is the discipline to make ambition real.
Principles
How we work
Radical Clarity
We cut through noise and complexity to find the signal. Every recommendation is grounded in evidence and free of jargon.
Relentless Momentum
Strategy without execution is a postcard. We design for action, build playbooks that teams can run, and stay close until results show.
Partnership, Not Performance
We embed with your team, share risk, and celebrate wins together. Our success is measured by the outcomes you achieve long after we leave.
Beyond the Obvious
The best ideas live at the edge of conventional thinking. We challenge assumptions and look for leverage others miss.
