TimeTeller’s innovative technology measures a patient’s circadian rhythm through saliva samples to pinpoint the optimal time for cancer treatments using computer algorithms. Our mission is to reduce chemotherapy side effects and enhance treatment efficacy. Currently used in clinical studies at several hospitals, TimeTeller aims for widespread adoption to transform cancer therapy. Chronotherapy can improve tolerability and effectiveness up to 5-fold, but practical tools have been lacking—until now. TimeTeller brings this breakthrough from research to real-world application, striving to improve patients’ quality of life, boost chemotherapy success, and lower treatment costs.
