Independent / Non-profit / Non-lobbying

Investment rules are fragmenting.
CELIS serves the field –
not a side.

CELIS provides small rooms and high trust for people who regulate cross-border investments and the people who do the deals.

What is CELIS

We are the independent, non-profit organisation dedicated to economic security and investment screening.

Across continents, we connect regulators, investors, law firms, and academia in a high-trust environment that rarely exists elsewhere.

Together with our stakeholders, we develop best practices and standards that shape the balance between investment security, open markets, and competitiveness.

What we do

We build trust at scale. But in small rooms

The CELIS Institute hosts invite-only, curated, high-level convenings such as the CELIS Forum on Investment Screening (CFIS), regional CELIS Thought Leaders, and focused dialogues rooted in legal and policy excellence, such as CELIS Leaders and CELIS Salon.

How to Participate

CELIS Events are high-level, trust-engineered convenings that shape best practices in investment security. We believe multi-stakeholder, closed-door dialogue is vital to effective economic security policy.

Our flagship event – the CELIS Forum on Investment Screening (CFIS) – is an invite-only, strict Chatham House, small room forum (capped at 60 speakers and 60 attendees). It brings together EU officials, national experts, diplomats, private practitioners, in-house counsel, academics, business leaders, think tankers, and civil society for candid, outcome-oriented exchange.

Other events include regional CELIS Thought Leaders focused on a cluster of national regimes for practitioners who need to master how screening actually works, and discreet and focused dialogues rooted in legal and policy excellence, such as CELIS Leaders and CELIS Salon.
