Why GEFIN

Institutional rigour, with the agility of a modern partnership.

Large banks bring discipline but move slowly. Independent advisors move fast but rarely carry institutional weight. GEFIN is built to do both. We combine the analysis and structuring discipline of institutional finance with the speed, candour, and hands-on focus of a partner-led firm.

We don't just advise. We structure, develop, and close — and we stay accountable to the outcome, not the mandate.

The discipline of institutional finance. The directness of people who answer for the result.

What we do

Three capabilities. One arc, from financial architecture to signed completion.

Most firms cover one part of a deal. We cover the whole arc — designing the structure, developing the project behind it, and carrying it to a close.

Capital Structuring

The financial architecture

We design the financial architecture of an operation — equity, debt, mezzanine, and fund structures engineered for the objective and the risk. The right structure is the difference between capital that moves and capital that stalls.

Project Development

Concept to investment grade

We take projects from concept to investment grade — feasibility, financial modelling, packaging, and the groundwork that makes capital deployable. We make a project something institutional capital can actually back.

Deal Closing

From the table to completion

We handle negotiation, syndication, and completion — bringing counterparties to the table and operations to an executed close. A deal isn't done until it's signed. We get it signed.

Work with us

Bring us the mandate. We'll bring the structure.

If you're weighing a structuring, development, or closing decision, a short and confidential conversation will tell us both whether there's a fit.

Start a conversation

We reply to every serious enquiry personally — usually within one business day.

Who we are

An international advisory boutique, built in London.

GEFIN Advisors International is a UK-incorporated firm working at the intersection of capital and execution. We serve institutions and corporates that need capital structured intelligently, projects developed to investment grade, and complex transactions brought to a close.

We are partner-led by design. GEFIN was founded by two principals — Raúl Lloveras Marcos and Paul Mena Zapata — who hold the firm in equal partnership. When you work with GEFIN, you work with the people making the decisions, not a layer between you and them. A London base, an international footprint, and discretion as the default.

Partner-led, by design. You work with the people making the decisions.

The approach

Senior people. Direct answers. The speed of the deal.

We keep teams small and senior. The person you brief is the person doing the work. That means fewer handoffs, faster decisions, and candour when it matters — including when the answer is no.

Partner-led from day one.

No junior layers, no diluted accountability. You deal with the principals throughout.

Aligned to the outcome.

We measure success by what closes, not by hours billed or decks produced.

Discreet by default.

Sensitive mandates handled with the confidentiality they require.
