What Celicourt Communications does

Celicourt Communications is a London-headquartered strategic communications consultancy founded in 2014 by Mark Antelme, a former Brunswick Group Director. The firm delivers a portfolio of ten interconnected advisory service lines spanning capital markets communications (IPOs, M&A, financial calendar support), investor relations, corporate communications, leadership communications, crisis communications and preparation (including 24/7 response), transactions communications (SPACs, divestitures, distressed situations), ESG advocacy aligned with the UK Stewardship Code (2020), bespoke campaigns, design and digital production, and media relations and coaching.

The business is built on senior practitioner expertise rather than proprietary technology; its core technology is the team's collective experience, with most senior professionals drawn from large international agencies and banks (Brunswick Group, Deutsche Bank, JP Morgan Chase, CIBC World Markets, RBC Capital Markets, Salamanca Group, Financial Dynamics, Bell Pottinger) plus a serving Senior Advisor who is a former investment banker. The partner-led engagement model reflects a deliberate boutique positioning versus larger agencies.

Celicourt monetizes through custom engagement-based professional services fees typical of the boutique advisory sector, with no publicly disclosed pricing or standard tiers and multi-year contracts observed. Its customer base spans enterprise corporations across natural resources (Ocean Infinity, Gulf Keystone, Gem Diamonds, Perenco), maritime and engineering (LOC Group), public companies, governments, and high-profile individuals. The firm has no external institutional funding, no parent company, and no disclosed subsidiary structure; it operates from a single London office (Chancery House, 53-64 Chancery Lane) and claims global reach through international client engagements.

Broad incumbents

• FTI Consulting (Strategic Communications): Large global consulting firm with a substantial Strategic Communications segment covering financial communications, M&A advisory, crisis, and public affairs. Comparable: serves many of the same capital-markets and corporate-reputation clients, but operates as part of a much broader consulting portfolio with significantly larger headcount and geographic footprint.
