Hexagon Bio

Hexagon Bio is a Menlo Park, California biotechnology company developing novel payloads for antibody-drug conjugates (ADCs) in oncology. The company designs next-generation ADC payloads intended to overcome resistance to current payloads and to expand the range of cancer indications ADCs can treat. Backed by SoftBank Vision Fund, Hexagon Bio operates a therapeutics pipeline and research platform rather than a public developer program: it publishes no API, SDK, or developer documentation surface. This profile was surfaced as a portfolio-company lead and enriched from Hexagon Bio's own public website (company, pipeline, science/platform, and news pages).
