Centralis Group, a global leading alternative asset and corporate services provider, recently acquired Admina Fund Services, an organisation founded and based in Guernsey.
Admina, now a Centralis Group company, is an experienced provider of fund administration and corporate services based on the island. Centralis provides a full suite of integrated fund administration and company secretarial services to regulated and unregulated, listed and unlisted closed ended limited partnerships, companies, trusts and foundations across multiple asset classes, including all related holding structures, management and carried interest vehicles. By joining the Centralis Group, existing clients of Admina will benefit from access to the wider Centralis service offering.
Centralis has established itself as an industry leading provider of customer-centric tailored services via 430+ highly experienced professionals. It is a global business that partners with alternative investment firms and corporate organisations, providing administrative, global expansion, and governance solutions tailored to each client’s unique needs. Headquartered in Luxembourg, Centralis now adds Guernsey to its growing list of office locations.


Elizabeth Fitzgibbons Butler, Global Chief Commercial Officer at Centralis, commented: “The acquisition of Admina is another important milestone for us as we expand our breadth of services to our Alternative and Corporate client base. Our new office will take us into the strategically important Channel Islands and also expand our fund administration capability. I am also pleased to announce that Gregorio Pupino has transitioned from his role as Head of Funds Luxembourg to Head of European Fund Services.”
Gregorio continued: “As we strengthen our presence in key jurisdictions, including our recent expansion into Guernsey through the acquisition of Admina, the team are evolving to support this broader European scope. This transition recognises our growing impact across the region. We are committed to expanding our fund services platform and reinforcing our position in multiple jurisdictions. I look forward to being part of driving forward our growth strategy.”
What are the benefits of working with Centralis in Guernsey?
International recognition: Guernsey is a sophisticated jurisdiction, and its regulations align with those of the US, EU, and UK, meaning there are fewer barriers to carrying out multi-jurisdiction transactions or building multi-jurisdiction business models.
Flexibility
Guernsey is very much ‘open for business’, meaning its regulator, the Guernsey Financial Services Commission (GFSC), is responsive to the needs of fund promoters and clients, offering fast approval times for new funds and a diverse range of fund types. This positive approach to business can be a key differentiator to other jurisdictions.
Tax neutrality
Guernsey is fully compliant with the international requirements of FATCA and CRS reporting. Its structures allow for capital to be deployed around the world without unnecessary tax burdens, and its tax regime is relatively straightforward and easy to comply with. Guernsey is a tax-neutral environment. No capital gains, inheritance taxes, or value-added taxes are imposed.
Political and economic stability
The island has a stable political climate and strong economic policies, giving comfort to investors where other regimes can be less attractive due to political and economic uncertainty.
Professional infrastructure
The island boasts a sophisticated financial services industry supported by expert legal and accounting services. Centralis Group is pleased to join some well-known and highly regarded companies in the market.
The team at Centralis Guernsey has a first-class reputation for their proactive client approach, and they bring additional expertise to the already flourishing Centralis team.
How Centralis is redefining fund administration
2025 is seeing a significant transformation in the approach to fund administration in the alternative investment industry, driven by evolving investor expectations, regulatory pressures, and the integration of advanced technologies. Centralis – already a trusted leader in fund administration – is at the forefront of this evolution, providing cutting-edge solutions and a co-sourcing model that enables fund managers to maintain operational control while accessing expert support. This tailored approach is transforming the way alternative investment firms navigate operational complexities, creating a pathway to success in a highly competitive market.
Co-sourcing: The future of fund administration
Co-sourcing is emerging as a superior alternative to traditional outsourcing in a sector that demands precision, adaptability and transparency. The Centralis co-sourcing model offers fund managers a unique hybrid approach: combining the benefits of in-house control with the expertise and scalability of a specialised partner. This collaborative framework enables fund managers to retain oversight of critical data and technology while leveraging Centralis’ extensive resources.
By choosing co-sourcing, fund managers avoid the trade-offs typically associated with outsourcing, such as loss of operational visibility or lack of customisation. Instead, they gain a seamless extension to their team, designed to address the unique challenges of their operations. This model allows real-time access to data, enhanced decision-making and a highly responsive service environment.
Key trends for 2025 in Fund Administration
Several pivotal trends are shaping fund administration in 2025, and co-sourcing aligns perfectly with these developments.
Technological integration: Automation, artificial intelligence, and blockchain are driving efficiency and transparency. Centralis integrates seamlessly with client technologies, offering expertise in leading platforms to ensure smooth operations.
Regulatory complexity: As compliance demands increase, co-sourcing enables fund managers to adapt proactively, ensuring adherence to evolving standards without overburdening internal teams.
