Njord Partners is a London-headquartered investment manager which manages over $1 billion in capital. Despite its substantial client base and industry recognition, Njord has maintained a relatively low public profile compared with larger special situations investors. However, the public record shows that it has hired APCO, the PR firm which focuses on reputation management. According to documents seen by the Guardian, what followed was an investigation by APCO into journalists and their sources. In the past, there have been media reports linking Njord Partners to Russian state-owned enterprises through its ownership of RETN, the major international network services provider, founded in Russia.
