Rainbow Labs

What Rainbow Labs does

Rainbow Labs is a UK-based private company, founded in 2021 and headquartered in Chelmsford, that develops diagnostic assays and lab testing services. Its offering centers on tools for assay validation, sample processing, and reporting — a workflow-oriented stack that suggests the company serves clinical or research customers needing structured diagnostic pipelines rather than ad-hoc testing alone. The business is led by Raja Mohan, who holds the dual role of Co-founder and Medical Director, providing clinical oversight of the assay portfolio.

Operationally, Rainbow Labs runs with a small team (11–50 employees) and operates from a single UK base. No funding rounds, investors, partnerships, certifications, or regulatory milestones are disclosed, and the product portfolio, pricing model, distribution channels, and customer segments are not detailed in available sources. The company's website is currently offline for scheduled maintenance to upgrade its systems, which the company characterizes as preparation for an improved customer-facing experience rather than a discontinuation. The combination of limited public footprint, undisclosed financials, and a temporarily offline web presence means that deeper diligence on revenue, traction, and commercial model is required before any investment view can be formed.
