## Summary

Simple PCR-based cancer diagnostics running on standard lab equipment to democratize complex disease detection; $7M raised May 2025 from YC S22 competing with Grail and Exact Sciences for accessible liquid biopsy.

## Company Overview

Signatur Biosciences is a London-based diagnostics company developing simple PCR-based tests that can detect complex diseases like breast cancer and other conditions using standard qPCR machines already present in most clinical laboratories — making sophisticated molecular diagnostics as accessible and operationally simple as a COVID-19 PCR test. Founded in 2022 and a Y Combinator S22 graduate, Signatur raised $7 million in May 2025 to scale its affordable, point-of-care compatible diagnostic solutions that address critical accessibility gaps in cancer diagnostics.

Signatur's smart PCR kit approach addresses a fundamental barrier in precision diagnostics: the most sensitive cancer detection tests (liquid biopsy, next-generation sequencing) require specialized expensive equipment and expert bioinformatics analysis that limits their use to major cancer centers. Signatur's tests use standard qPCR machines (which exist in regional hospitals, clinical labs, and diagnostic centers worldwide) and proprietary assay design that extracts equivalent diagnostic information from simpler equipment — democratizing access to early cancer detection beyond specialized oncology centers.

In 2025, Signatur Biosciences competes in the molecular diagnostics and liquid biopsy market with Exact Sciences (Cologuard, Nasdaq: EXAS), Grail (Galleri multi-cancer early detection, Illumina), Foundation Medicine (Roche), and Guardant Health (GUARD) for cancer early detection and molecular diagnostics. The liquid biopsy and multi-cancer early detection space has attracted significant investment — Grail's Galleri test (which screens for 50+ cancers from a blood draw) represents the aspiration of the field but requires specialized sequencing infrastructure at $949 per test. Signatur's PCR-based approach could achieve widespread adoption if it delivers comparable clinical sensitivity on accessible equipment. The $7M May 2025 raise provides the runway to complete clinical validation studies. The 2025 strategy focuses on breast cancer as the lead indication, building the clinical evidence base for regulatory submission, and establishing NHS and international diagnostic laboratory partnerships.
