Exact Sciences Corporation

A diagnostics company focused on early cancer screening, Exact Sciences makes Cologuard—a stool-based test people collect at home to spot colorectal cancer, a noninvasive alternative to a colonoscopy. Founded in 1995 in Massachusetts by Stanley Lapidus and Anthony Shuber, it built Cologuard alongside the Mayo Clinic, and the FDA cleared the test in 2014. The name blends "colo" for colon and "guard," underscoring the test's protective role.
