Clinical Trials are the biggest bottleneck in bringing new drugs, devices, and vaccines to patients. On average, getting a new drug through the trial process takes nearly a decade and frequently costs $1B+. To make it worse, the process is inflicted with a great number of transparency issues. We are aiming to solve this through technology and platformization of clinical trials. We develop and offer next-generation technology platforms to pharmaceutical and biotech companies for running their clinical trials by integrating the entire process in an end-to-end workflow. Since Day 1, our vision is to make clinical trials faster, seamless, accessible to patients, and more transparent. We are driven by our technology-first approach to reduce inefficiency and increase patient-centricity in Clinical Trials.
