Who we are · since 2023Advisory and principal investment under one roofFiled from Dubai

An independent strategic advisory & investment group.

We advise and invest alongside a small number of governments, institutions and private clients on matters of strategic consequence. Our work speaks through outcomes, not disclosures.

Our mission

To originate and accelerate transformational initiatives capable of creating long-term economic and investment value — combining strategic advisory with principal investment.

Our vision

To be the discreet, trusted counsel institutions turn to at the moments that matter most — and a principal investor prepared to stand behind its own convictions.

Four disciplines, one standard of execution.

Our core capabilities run from the first strategic assessment through to the transaction, the capital behind it, and the years of execution that follow. Each is offered on the same terms as the last.

01Advisory

Corporate strategy

We advise where decisions carry consequence — helping boards, executive committees and sovereign institutions navigate complexity with clarity and conviction. Our counsel is sought at the moments that will define an institution's next decade, not its next quarter.

Much of this work is never disclosed. It exists in closed rooms, at inflection points, where judgement matters more than process — and where the value of advice is measured by what it prevents as much as by what it achieves.

“Their perspective changed the trajectory of a decision that would have taken us years to reach alone.”

Chairman · European industrial group

02Transactions

Mergers & acquisitions

We identify, structure and execute transactions before they become visible to the market — often originating the opportunity itself rather than responding to a process already in motion.

From first assessment through post-transaction integration, we remain present at every stage, protecting value at the points where it is most exposed and most easily lost.

“They operated with a level of discretion and precision we rarely encounter in this market.”

03Capital

Private capital deployment

We do not simply recommend where capital should go — we deploy our own alongside our clients, sharing the risk, the timeline and the outcome. This is capital committed with conviction, in ventures we have chosen to build ourselves.

It is a distinction few advisory firms are structured to offer, and one that shapes every recommendation we make: we do not advise on decisions we would not make with our own capital.

“Few advisers are also willing to invest their own capital. That alignment changes the nature of the conversation entirely.”

04Execution

Industrial transformation

We design and deliver transformation at scale, for organisations operating in complex, capital-intensive environments — where the cost of hesitation is measured in decades, not quarters.

Our role continues long after the strategy is approved: through execution, resistance, and the slower, harder work of making change stick inside an institution.

“They stayed engaged well beyond the point most advisers disappear.”

What they say, across the relationships we maintain.

A second, dedicated testimonials section, distinct from the discipline-level quotes above, gathering perspectives from across the four types of relationship Green PowerHouse maintains: client, transaction counterparty, co-investor and institutional partner.

Client

“When the stakes are this high, you don't want a consultant. You want someone who has actually built and run something themselves. That is the difference with Green Powerhouse.”

Group CEO, publicly listed industrial company

M&A Counterparty

“We had multiple bidders at the table. Green Powerhouse was the only one who understood the business as an operator, not just as a buyer.”

Former majority shareholder, acquired portfolio company

Investor

“They co-invest alongside us rather than simply presenting opportunities. That alignment of interest is rare, and it shows in the quality of the decisions.”

Managing partner, institutional co-investor

Government & Institutional Partner

“Few advisers understand both the commercial and the sovereign dimension of a project of this scale. Green Powerhouse moved fluently between both.”

Senior government official, ministry of economy
