About Spear Bio

Spear Bio is an early-stage diagnostics company commercializing its patented SPEAR (Successive Proximity Extension Amplification Reaction) technology, invented at Harvard's Wyss Institute. The platform's key innovation is a two-factor authentication mechanism that drastically reduces background noise, enabling attomolar-level detection of protein biomarkers from just 1 µL of sample without complex wash steps. This positions the company to address critical needs in biomarker research and clinical diagnostics where sensitivity and sample volume are limiting factors.
