Executive Summary
Micromine is a Perth-headquartered mining software company whose Pitram platform is a widely used mine-production and fleet-management system. Callum spent five and a half years there, across two roles: two years in Micromine's global product team working on Pitram, then just over three years as Commercial Lead for Pitram across the Asia-Pacific region. That tenure ran almost the full length of Potentia Capital's ownership of Micromine — from its December 2018 majority-stake investment through to early 2025 — a period in which the business grew substantially before Potentia's eventual sale of Micromine to Weir Group plc. Within his own commercial remit, Callum held revenue forecasting and account accountability across close to two dozen Australian mining operations, closed seven multi-year production-system agreements with Tier-1 and Tier-2 clients, and grew the underground segment to an estimated 80 per cent share of the Australian market.
The Challenge
When Callum moved from Micromine's global product team into commercial leadership for Pitram across APAC in 2021, the business needed to convert deep technical capability in an underground mine-production system into a repeatable, scalable commercial engine. Pitram's market is technical and relationship-driven: contracts typically run for multiple years, switching costs are high, and buying decisions sit with mine management, technical services and procurement teams inside multinational mining companies — not with a single commercial contact.
The commercial task sat inside a wider context. Micromine had taken on Potentia Capital as a majority shareholder in December 2018 with an explicit growth mandate, and the business was expected to keep expanding its revenue base, its customer footprint and its product portfolio through bolt-on acquisitions over the years that followed. Growing an underground production-system business in that environment meant closing complex, multi-year agreements against a defined commercial target, without the benefit of an established sales playbook for every account, and doing so across a portfolio of operations spread across the country.
Callum's Role
Callum held two consecutive roles at Micromine, working for Micromine directly — not as a client-side operator and not on behalf of Nausicaa Consulting, which did not exist at the time.
From 2019, as part of Micromine's global product team, he worked on Pitram's product direction and requirements, building a detailed understanding of how the platform was used on live mine sites — material tracking for grade control, equipment time-usage and productivity monitoring, and integration with underground communications networks. From 2021, he moved into commercial leadership for Pitram across the APAC region, holding revenue forecasting and account and pipeline accountability across roughly two dozen Australian mining operations, and negotiating commercial and contract terms directly with the procurement and legal teams of multinational mining companies.
Approach
From product knowledge to commercial ownership
Callum's two years inside Micromine's global product team gave him a working understanding of Pitram's technical capability and how mine sites actually used it — knowledge he carried directly into the commercial role that followed. Rather than a conventional sales handover, the transition let him negotiate from a position of technical credibility with client mine-management and technical-services stakeholders.
Portfolio and revenue discipline
He held revenue forecasting and account and pipeline accountability across close to two dozen Australian mining operations, and led a twelve-month campaign that grew annual revenue across that portfolio by an estimated 150 per cent from the same cost base — without losing a client in the process.
Enterprise negotiation at scale
He closed seven multi-year production-system, software and consulting agreements with Tier-1 and Tier-2 mining clients over five years, typically in the $0.5M–$2.5M range, negotiating commercial and contract terms directly with the procurement and legal teams of multinational mining companies.
Market development
Callum grew the underground segment to an estimated 80 per cent share of the Australian market, and oversaw the deployment of Pitram production systems across seven new mine sites over four years — extending Micromine's footprint in a competitive, technically demanding product category.
Cross-functional delivery
He mapped mining improvement processes across mine management, technical services, production, maintenance and operational technology stakeholders, and led cross-functional technical and account teams from contract signature through to delivered outcomes on client sites.
Outcomes
- ✓Revenue growth without account loss. Led a twelve-month campaign that grew annual revenue by an estimated 150 per cent across a ~24-operation Australian portfolio from the same cost base, without losing a client.
- ✓Market share gained. Grew the underground segment to an estimated 80 per cent share of the Australian market.
- ✓Seven new multi-year agreements closed with Tier-1 and Tier-2 mining clients over five years, typically in the $0.5M–$2.5M range.
- ✓Seven new site deployments of Pitram production systems delivered over four years.
- ✓Portfolio accountability sustained — revenue forecasting and account/pipeline ownership across roughly two dozen Australian mining operations throughout the commercial-lead phase.
- ✓Continuity through a private equity ownership cycle. Five and a half years of continuous service spanning almost the entire period of Potentia Capital's ownership of Micromine, which culminated in Potentia's sale of the business to Weir Group plc — completed in April 2025 at a reported enterprise value of roughly A$1.3 billion — a matter of months after Callum's own departure from the company.
Why It Matters
This profile shows an executive who built genuine technical credibility before taking on commercial ownership — and who then converted that credibility into measurable growth inside a company under active private-equity ownership, where the pressure to expand revenue and market share was explicit and sustained. Closing multi-year agreements directly with the procurement and legal functions of multinational mining companies, holding forecasting accountability across a national portfolio, and growing market share in a competitive technical category over several years are the kind of commercial fundamentals that transfer directly to any resources, infrastructure or technology business built around long sales cycles and high-value client relationships.
Capabilities Demonstrated
This profile describes Callum's personal experience as an employee of Micromine across two consecutive roles. It does not represent work delivered by Nausicaa Consulting, and Callum was not involved in, and had no role in negotiating, Potentia Capital's investment in Micromine or its subsequent sale to Weir Group plc. His employment with Micromine concluded in January 2025, shortly before Weir's acquisition of Micromine was publicly announced (28 February 2025) and completed (30 April 2025).
