DENNIS BARTOW

Founder · President & CEO — Polemarchoi · Polemetallon · Dīs Pater

Dennis Bartow is a decorated, service-disabled retired U.S. Army combat veteran — 29 years of honorable service, 23 of them in support of Army Special Forces and Special Operations units — and a former senior official of the U.S. Department of Defense. He served as Deputy Assistant Secretary of Defense for African Affairs Policy, the Department's most senior official dedicated to Africa policy, advising the Secretary of Defense, helping lead the Department's global strategic-competition effort, overseeing the writing of its Great Power Competition strategy, and standing among the plank owners of the Prosper Africa interagency framework. As Director of the DoD Office of Small Business Programs, he was the Secretary's principal advisor on small business, leading a network of more than seven hundred professionals across a fifth of all defense procurement. Earlier: INTERPOL Washington — identity intelligence and a five-nation Gulf of Guinea counter-piracy program — and five years of congressional staff service, with senior staff and advisory roles reaching the White House, Senate, and House.

He founded Polemarchoi — named for the senior military leaders of the Greek world — as the strategic advisory firm serving companies where defense, energy, and strategic materials meet. What began as counsel became a platform: six years in the minerals space, from Defense Production Act, DOE Loan Programs, and EXIM financing campaigns to commodity trading, project development, and now ownership of the assets themselves.

Today he is Founder, President & CEO of all three companies; Senior Advisor to the DARPA Critical Minerals Forum; Advisor to the Duke University Critical Minerals Hub; and works with the University of Virginia's Frank Batten School of Leadership and Public Policy and its National Security Data and Policy Institute. The team he leads is drawn from military, special-operations, and government backgrounds — service at the most sensitive and highest levels of government and industry.

The three companies are the arc of that career made permanent: Polemarchoi, the strategy. Polemetallon, the supply. Dīs Pater, the source.

Operating Team

One bench. Distinct disciplines.

Polemarchoi's principals work across commercial, legal, operational, technical, and investment questions as one integrated team. Each mandate is led by the people doing the work—not handed down through layers of account management.

Robert Pearson

Business & Legal Affairs

Leads agreements, commercial structures, governance, collections, and partner diligence. As founder and CEO of OHD Partners, he also brings experience in sustainable infrastructure and cross-border development.

O'Rian Hairston

Chief of Staff

Runs the operating cadence behind the platform—coordinating priorities, diligence, meetings, travel, and deal execution across national-security, strategic-materials, and defense-technology work.

Mike Keller

Strategic Advisor

Advises on strategy and execution across critical-material, industrial-base, and market-development mandates, helping pressure-test opportunities and turn them into actionable partner and client workstreams.

Kyle Ballarta

Senior Advisor for Strategy

Brings venture, technology, and company-building judgment. He is founder and CEO of Falkon Ventures, was part of LifeProof's founding team, and co-founded Citadel Drone Defense.

Extended operating bench

Mandates draw on a trusted network of former senior national-security officials, special-operations leaders, industrial operators, sanctions and compliance specialists, materials traders, project developers, and capital advisers. The bench is assembled for the mission; client and government relationships are never presented as company affiliations.

The Discipline

Policy, regulation, and procurement shape the market.

Every line of this work lives or dies on sanctions treatment, export controls, tariff exposure, and government pathways. Our edge is the discipline to screen honestly — and structure around the exposure rather than ignore it.

STOP

What cannot be cleared is declined. Walking away from exposure is a capability, not a cost.

SLOW

What can be structured is structured — origin scrutiny, licensing pathways, counsel before movement.

GO

What clears, moves — material competitors cannot touch, delivered to allied end users.

That screening discipline is why the material commands a premium, why government engages, and why the work matters strategically rather than merely commercially.

Workflows

Six workflows, applied where needed.

The portfolio is diverse; the operating motions repeat. Polemarchoi connects the right workflow to the right decision-maker and carries it through the public, financial, technical, and commercial system.

Government & policyFederal positioning

Agency strategy, appropriations, legislation, regulatory engagement, briefing campaigns, and decision-maker outreach.

Capital formationPublic and private finance

Applications and strategy for grants, loans, guarantees, development finance, strategic investment, and venture capital.

Acquisition & contractingPrograms and vehicles

Technical proposals, white papers, other-transaction pursuits, program-office positioning, and contract-vehicle strategy.

Industrial strategySupply-chain resilience

Raw-material access, processing, logistics, stockpile positioning, allied supply, qualified end users, and off-take pathways.

Commercial strategyMarket entry and partnerships

Competitive positioning, host and sovereign engagement, strategic partnerships, customer pathways, and capital-ready narratives.

Decision supportAdvisory and diligence

Rapid operating assessment, policy intelligence, open-source analysis, technical framing, and a practical sequence of action.
