About Castil Advisory

Castil Advisory is an independent investment banking boutique composed of senior deal-makers delivering judgment-driven, strategic advisory with absolute alignment to client outcomes.

Castil Advisory is built to provide independent judgment and senior-led execution
in the most demanding financial situations.

Castil Advisory was founded in October 2014 to address a clear observation: as transactions become more complex, more international and more strategic, senior judgment and independence become criticial and relevant.

Castil Advisory is a compact, high-conviction advisory platform, designed to operate outside institutional constraints and transactional pressure, with a single objective: serving clients’ long-term strategic and financial interests.

Since its creation, Castil Advisory has evolved into an international advisory boutique, operating across France, the European Union and the UAE / MENA region, and advising on complex M&A, capital raising and financing situations across industries.

Our approach

Independent.
Senior-led.
Bespoke.

Castil Advisory provides partner-led, relationship-driven advice grounded in trust and discretion, with senior partners leading each mandate end-to-end in complex, time-critical situations.

Our values

  • We believe the best outcomes come from creative structuring.

    Our approach blends:

    • financial engineering,

    • strategic imagination,

    • and negotiation artistry.

    Great deals are not found — they are designed.

  • Deep technical expertise is the backbone of our work:

    • valuation,

    • structuring,

    • regulatory frameworks,

    • cross-border tax and legal considerations,

    • capital markets and financing mechanics.

    Our clients rely on us for intellectual rigor without noise.

  • We specialize in complex, high-stakes situations and handle them with:

    • rigorous analysis,

    • absolute discipline,

    • and meticulous execution.

    Complexity is not something we manage around.
    It is what we master with precision.

  • We bring wit, creativity and human intelligence to situations where formulas fail.

    Markets are driven by people.
    Deals succeed when one understands psychology as well as numbers.
