Spear Bio
Spear Bio is a Woburn, Massachusetts biotechnology company commercializing SPEAR (Successive Proximity Extension Amplification Reaction), an ultra-sensitive, wash-free immunoassay platform licensed from Harvard's Wyss Institute. SPEAR measures protein biomarkers at attomolar levels from sub-microliter samples using a two-factor authentication mechanism and standard qPCR instruments, delivering more than a 5-log improvement over conventional ELISA. The company sells assay kits - initially for neurodegeneration biomarkers such as pTau217, pTau231, GFAP and neurofilament light - to academic, pharmaceutical and clinical researchers.
Feng Xuan
Feng Xuan is a Boston-based scientist-entrepreneur and the co-founder and CEO of Spear Bio, a biotechnology company building ultra-sensitive immunoassays for protein research and early disease diagnostics. He invented the company's core SPEAR (Successive Proximity Extension Amplification Reaction) technology as a Technology Development Fellow at Harvard's Wyss Institute, translating a decade of research in molecular and immuno-diagnostics into a platform that can measure minute quantities of protein biomarkers from sub-microliter samples. Under his leadership, Spear Bio raised an oversubscribed $45 million Series A in 2024 and earned FDA Breakthrough Device Designation for a blood-based pTau 217 test aimed at early Alzheimer's disease detection.
Algorithmic Biologics
Algorithmic Biologics is a Bengaluru- and Delaware-based deep-tech company that treats molecular testing as an information-processing problem. Founded by molecular-computing researcher Dr. Manoj Gopalkrishnan, its patented Tapestry platform uses compressed sensing and combinatorial pooling to run large-scale DNA/RNA/protein tests with far fewer reactions - screening many samples at once and only zooming in where a signal exists. The approach first proved itself as an award-winning, regulator-approved COVID-19 pooling solution and now targets affordable genomics, multiplexed diagnostics, and accelerated assay design.
Hiranjith H
Hiranjith H (also Hiranjith GH) is the Chief Business Officer of Algorithmic Biologics, a Bengaluru-founded deeptech startup that embeds algorithms inside test tubes to make molecular testing dramatically cheaper and faster. Based in the San Francisco Bay Area, he leads the company's commercial operations and US expansion. He spent more than a decade scaling MedGenome's research-services business in the US and earlier built commercialization and analytics strategy for life-sciences clients at Novartis, ZS Associates, and Accenture Management Consulting.
