About us
An independent partner, owner-led and fully regulated.
Atdomco Investor Services is the Luxembourg fund and corporate administration company of Atdomco Group, which has served alternative investment managers since 2013. Authorised as a specialised professional of the financial sector (PFS) on 31 August 2026, we are supervised by the CSSF.
Backed by IRE AIFM, the Group's CSSF-authorised alternative investment fund manager, we can take a fund from set-up to investor reporting within one coordinated, regulated platform — while staying small enough to know every mandate personally.

Our approach01 02 03
Advisory‑led. Technology‑enabled. Lean by design.
We are not a technology company. We are a service company that takes technology seriously — and puts it to work for our clients.
Advice that comes with a solution
Advisory is in our DNA. We never stop at the diagnosis: every recommendation comes with a concrete, workable answer — a structure, a process, a timeline. That is what being client-centric means to us.
Agentic AI, applied with judgement
We have deliberately embraced agentic AI and digitalisation wherever they create real business value — streamlined onboarding, automated controls, faster and more reliable reporting. Technology supports our experts; it never replaces their accountability.
Lean processes, competitive fees
Our operating model is lean by design, with no layers of overhead. We pass that efficiency on to you: attractive pricing compared with larger providers, with no compromise on service level, control or regulatory standards.
The result: institutional-grade service, on a boutique cost base.
Why Atdomco
Boutique attention, institutional standards.
Fully independent
No bank, private equity firm or other third party holds an interest in the Group. Your interests stay central to every decision.
Owner-led
Our partners work on client mandates day to day — you deal directly with the people who make the decisions.
Alternatives expertise
Decades of hands-on experience across private equity, real estate, private debt, venture capital, fund-of-funds and securitisation.
Central & Eastern Europe
A 25-year track record with CEE promoters and investors.
One integrated platform
Robust, scalable operations with an affiliated AIFM — we can take on full, co-sourced operational responsibility.
Responsive by design
Tailored and proactive: we anticipate your growth rather than simply respond to it.
Governance
Accountable people, clear oversight.
