Delee

Delee is a Monterrey-based medical device company whose CytoCatch system isolates and analyses circulating tumour cells from a blood sample for early diagnosis and treatment monitoring. It was one of the first Latin American oncology device companies through YC. The YC directory lists it as active, but the company domain no longer resolved to a company site when checked on 2026-09-10 and no peer-reviewed clinical validation of a marketed test was found, so its current status and evidence should be treated as unverified.
