About | OneOverNil

An independent advisory practice operating outside traditional consulting models.

Focused on complex decisions in the resources and natural assets sector.

OneOverNil was established to operate in a space between conventional consulting, research, and product development, where complex decisions require both analytical depth and senior judgement.

The practice is intentionally small, selective, and independent, allowing work to be shaped by the problem at hand rather than by delivery models or scale considerations.

What We Focus On

The work of OneOverNil centres on complex technical and commercial decisions in the resources and natural assets sector.

Engagements often sit at the intersection of data quality, system behaviour, uncertainty, and long-term operational or investment risk.

How The Practice Is Structured

OneOverNil operates as a principal-led practice. Engagements are delivered directly, with specialist partners engaged selectively where required by domain or scope.

This structure supports depth, continuity, and discretion, and avoids the incentives and constraints associated with larger delivery-led organisations.

Principal

OneOverNil is led by Ishant Kohli.

Ishant works at the intersection of analytical modelling, digital development, and decision support in the resources and natural assets sector.

His work spans advisory, product development, and applied modelling, supporting technical due diligence, investment decisions, and operational reviews.

Experience and Context

Experience includes advisory, analytical, and product-oriented work with global and Australian resource operators, service providers, and academic institutions.

This work has supported technical and commercial due diligence, investment decisions, operational reviews, and the development of decision-support tools.

Relationship to Research and Products

Analytical development, modelling, and applied research are integral to how OneOverNil works, whether expressed through advisory insights or embedded in digital and analytical products.

Much of this work is internal and context-specific, allowing methods and tools to evolve without constraint and client contexts to remain protected.

OneOverNil is not positioned to compete on volume or breadth of services, but to work selectively on problems where depth, clarity, and judgement materially affect outcomes.
