The ACi is an international non-profit established by corporate investigators to serve the diverse needs of our community — from newcomers to seasoned professionals, across every industry. Every member of our Executive Committee is a senior in-house investigator in a full-time investigations role, which keeps our work grounded and relevant.

Investigations are part of corporate DNA. The global investigations community — and all its related services and technology specialists — is estimated to exceed 500,000 people. The ACi exists to serve and to build this growing community, actively championing diversity, equity and inclusion as central to our member-led mission.

We undertake training and research to advance the profession, providing platforms for thought leadership, cross-industry insight, networking and centralised resources — and we are proud contributors to the new ISO standard for internal investigations.

The ACi Corporate Investigators Handbook brings together the collective practice of senior in-house investigators worldwide — from triage and scoping through evidence handling, interviewing, reporting and stakeholder management. Recognised by the International Compliance Association in its Multi-Stakeholder Collaboration category.

Available free as an online edition through Global Investigations Review.

ACI was founded by practitioners who knew the loneliness of difficult cases — and the value of a phone call to a trusted peer. Today, that quiet network is becoming a global profession.
