2023
Warning signs emerge: patient cac too high for out-of-pocket cancer care.

Shutdown announced. Root cause: sub-scale patient acquisition led to a quiet strategic acquisition by apollo hospitals.
Root Causes
Onco was an Accel-backed cancer care coordination platform founded in 2018 in Bengaluru, offering second opinions, treatment planning and remote monitoring for cancer patients across India. In December 2024 Apollo Hospitals quietly acquired Onco in what was disclosed only in mid-2025 via CXO Digital Pulse reporting. The deal folded Onco's technology and clinician network into Apollo's oncology practice; financial terms were undisclosed but sources indicated a modest strategic price consistent with Onco's ~$7M raised. Onco is the archetype of the Indian health-tech soft landing: strong product, thin revenue, hospital chain absorbs.
