Black Rainbow

What Black Rainbow does

Black Rainbow is a UK-based private software company founded in 2017 that builds NIMBUS, an integrated investigation case management, intelligence, and digital forensics platform. The NIMBUS ecosystem comprises three core modules — NIMBUS Intelligence, NIMBUS Investigator, and NIMBUS Forensics — supplemented by NIMBUS QMS for ISO 17025/17020 accreditation support, and adjacent products NIMBUS Clarify (security operations) and NIMBUS Shadow (major incident investigation). The platform is offered via cloud (NPRIMT-compliant, PASF-certified) or on-premise deployment, with a technology-agnostic orchestration layer enabling unlimited third-party integrations and configurable dashboards for real-time case oversight.

The company sells primarily to UK and US law enforcement agencies, government bodies, and large corporate customers in financial services and fraud investigation. Revenue is generated through enterprise subscription contracts for the NIMBUS platform, typically multi-year and procured via direct field sales, the GOV.UK Digital Marketplace, and demonstrations at industry conferences such as Techno Security, IACIS, and the National Intelligence Conference. Notable customers include Dallas Police Department, Police Scotland, and an unnamed global financial services firm. In March 2025, Black Rainbow secured an exclusive £15.2 million contract with the UK Police Digital Service to become the sole supplier of NIMBUS for case management across UK law enforcement.

Black Rainbow holds ISO 9001:2015, ISO 27001:2022, and Cyber Essentials Plus certifications and operates with 11–50 employees across offices in Ipswich (UK) and Reston, Virginia (US). Its leadership team is composed of former investigators and law enforcement officials, including a retired DHS Homeland Security Investigations Division Chief as Chief Product Officer and a former Metropolitan Police Senior Investigating Officer who led the Grenfell Tower criminal investigation.
