Frequently asked questions

Frequently asked questions about our references.

  • Because a case study requires the client's written sign-off on the numbers published. Many organizations — especially in the public sector and in cybersecurity — prefer not to document their environment publicly. Unpublished references are provided on request, over a call.

    Ask for references
  • Yes. Every published KPI — timeline, user count, savings achieved — is reviewed and approved by the client before publication. When a figure cannot be shared, it is removed rather than rounded or estimated.

  • Published cases range from a manufacturing SMB under 100 employees to an 11,000-employee enterprise across 30+ sites. The persona pages group engagements by profile: SMB, enterprise, public sector.

  • Yes, at the proposal stage. io4 connects you with a client of a comparable profile — same sector or same size — with no intermediary and no script. It is usually the most useful thing a prospect can ask for.

  • Weekly follow-up and quarterly governance exist so the gap shows up early. On a fixed-scope engagement, a change in scope goes through an explicit amendment — never a surprise invoice at the end of the project.
