TimeTeller pitches saliva test to time cancer therapy to body clock

German startup TimeTeller, led by CEO Angela Relógio, showed its saliva-based circadian profiling kit at TechCrunch Disrupt Startup Battlefield in San Francisco on October 14, 2026. The test measures activity in core clock genes — the genes that run the body's rhythm — to schedule cancer treatment to a patient's internal clock, aiming to reduce side effects and improve outcomes.
