A saliva test to time cancer treatment with the body's inner clock

German startup TimeTeller, led by CEO Angela Relógio, presented its saliva-based body-clock test at TechCrunch Disrupt Startup Battlefield in San Francisco on October 14, 2026. The test uses saliva to read how a patient's daily body rhythm is running, like checking their inner clock, to pick the best time for cancer treatment, aiming for fewer side effects and better results.
