We help fund managers, financial institutions, DFIs and the organisations they finance put business integrity into practice.
Definirs started as an abbreviation: DeFinIRS—Development Finance Integrity Risk Services. The capitals have softened since; the focus has not.
We founded Definirs in September 2023 after years on the inside: in banks, in supervision and in development finance, watching the same pattern repeat. Integrity was treated as paperwork—policies written to satisfy a request, filed, and forgotten until the next due diligence. Organisations paid for that gap in ways that never showed up as a line item: longer processes, harder questions from investors, and conditions attached to capital that better-prepared peers never saw.
Definirs exists to close that gap, structurally.
Our work does not end with findings—it ends when Business Integrity works in practice: proportionate to your organisation, owned by your team, and able to stand on its own.
We have no stake in the outcomes we assess, and we will tell you honestly what we see—including when we believe you do not need us.
