About Octant Advisory

Built Together.
Proven at Scale.

Octant Advisory is an independent AI diagnostics and advisory firm founded by Maria Chaloux and Dr. Ian McCulloh. We help boards and senior leadership teams identify the organizational conditions constraining AI performance, then sequence the governance, leadership, and operating-model changes that make it perform.

Our independence is deliberate: we do not sell technology or implementation.

The Experience
Behind the Advisory

In 2018, Accenture Federal Services committed to AI market leadership. Maria Chaloux, who had spent five years building and leading AFS's executive talent function, was tasked with hiring the leadership team that would make it real. The mandate was unambiguous: find practitioners who could build and run an AI practice at national scale.

She recruited Dr. Ian McCulloh as Chief Data Scientist, bringing a rare combination of two decades of applied AI research, 20 years of military service including leading information warfare strategy at CENTCOM, and the organizational credibility to lead in a demanding enterprise environment.

Over the next four years, Maria and Ian worked in close partnership, she building the leadership layer, he leading the practice’s AI delivery. Together they were part of the AI practice at Accenture Federal Services, delivering AI programs across the U.S. federal government.

“I’ve been part of hundreds of AI initiatives and talked with thousands of executives running them. AI underperforms when the technology gets deployed into an organization that isn’t ready to support it. The mandate, the leadership, the governance, data strategy, and operating model have to come first.”

Experience Earned in Execution

The experience behind Octant was earned in operating and delivery environments, not only in advisory settings. It was built under real enterprise performance pressure, with careers and outcomes on the line. What Octant delivers is grounded in what actually produces results at scale.

At Accenture Federal Services she led executive recruiting alongside the CEO and COO; when AFS committed to AI market leadership in 2018, she built the AI practice leadership team, recruiting Dr. Ian McCulloh as Chief Data Scientist. As Co-Founder and Managing Partner of Octant, she leads executive leadership assessment and organizational-design advisory, aligning leadership, governance, and operating models so AI investment produces sustained performance.

The AI practice Ian helped build at AFS delivered some of the most consequential AI programs across all 15 cabinet-level federal agencies and represents some of the most advanced applications of AI deployed by the U.S. Government. What made it work wasn’t just technical depth. It was the organizational discipline, and the talent Maria put in place around him. That combination, brought to enterprise clients, is genuinely differentiated.

Ian has been a driving force in scaling AI and data science capabilities across both the private and public sectors. I’ve had the opportunity to work alongside him in leadership roles in both environments, and his ability to navigate complexity, build high-impact AI led organizations, and deliver results consistently sets him apart. In a period defined by rapid technological change and the rise of AI, Ian is the kind of technical leader any organization would be fortunate to have.
