The Integrity Initiative set up a number of foreign 'clusters' (i.e. cells), comprised of people of influence, with a single leader. This is a standard method of compartmentalisation.
The first page of the Integrity Initiative handbook includes the following description of an effective cluster:
“An effective network is best achieved by forming in each European country a cluster of well-informed people from the political, military, academic, journalistic and think-tank spheres, who will track and analyse examples of disinformation in their country and inform decision-makers and other interested parties about what is happening.”
(30 May 2018) 
After the first Integrity Initiative Leak, Stephen Dalziel published on their (now defunct) website "This international project brings together in a network of clusters across Europe and North America people who understand the threat posed to Western nations by a flood of disinformation, deception and lies which is being put out by those opposed to Western concepts of liberalism, freedom and democracy. Countries such as Russia, China, Iran and Venezuela and entities such as Daesh are showing increasing sophistication in their attempts to influence the policies and undermine the societies of the West, which, despite flaws and failures, remain broadly democratic."
The Integrity Initiative handbook includes the following advice: “Be absolutely sure you have good references for people so we know we can trust them before we talk to them about our programme” 
The same document continues “* Chris Donnelly makes initial country introduction with nominated trusted 'coordinator' & relevant II team member/s (normally 2 members minimum per country)
- II team member/s coordinate foundation workshop to connect members, formally introduce them to II aims, establish target programme for research, dissemination and events. Members to sign code of conduct & non-disclosure Greg Rowett to start code of conduct doc to include basic info on passwords and etiquette with social media etc - final ok should be sought from James Wilson. Debate and decide preferred methods of communication. Activity: £3k budget (based on 20 clusters)”  It also points out that the "Professional comprehensive country.. can be anonymous".
The group's handbook contains a section on "Expanding our cluster network", in which the section on "approaching the topic" instructs readers to "Be absolutely sure you have good references for people so we know we can trust them before we talk to them about our programme". The same section lists questions to ask potential new members: “What access do they have to the individuals or groups we might want to see represented in a cluster (e.g. journalists, politicians, civil servants, military, academics, business etc.)? What are their capabilities/competencies for: research & analysis; networking; mentoring, conference organising, dissemination (writing, translating, public speaking, publishing, broadcasting)?” 
The file xCountry.pdf from the first Integrity Initiative Leak alphabetically lists the large nation states of Europe, and the US, together with the timing of their next election. Along side most of these countries are a set of people, email address and institutional affiliation.
The cluster network is almost exclusively in Europe, although it had apparently set up Australian and US Clusters, and was planning to expand its reach.Dan Kaszeta's notes for speaking in Israel include the claim that "We have good contacts in government in UK and other governments (Argentina, Baltic States, Lithuania, etc.") Cluster_Roundup_Jul18.pdf mentions that “The Integrity Initiative has the opportunity to develop the programme into North America, based on the Institute’s subsidiary, the Institute for Statecraft and Governance, which has a simple office in DC and is in the course of registering as a US 501 c 3 not-for-profit organisation.” 
However, the Institute's focus is not completely European; file xOutreach.pdf contains the text "Marcel R.D. CHIRWA firstname.lastname@example.org Malawi" and Leak#4 contains a draft meeting proposal with Donal Duke, who "is very likely to be a candidate in the next presidential elections in Nigeria" and Active Measures CND Integrity Initiative visit to Oslo.pdf which mentions Chris Donnelly's "Meeting with Cecilie Prebensen and E Africa team, National Youth Council, re Daesh info and the radicalisation of youth".
The group's FCO funding application for phase 2 detailed that “Experience in Phase 1 has shown that, once a cluster has been established, measurable impact can be expected within 3 months and the cluster is fully effective within 6 – 9 months.”
