Our mission is to exponentially improve drug development and the practice of medicine by learning from the care journey of every patient. We do it by developing novel AI and data pipelining technologies that can connect medical centers across the world and make sense of both unstructured and structured clinical data.

There have been many failed attempts to build a similar platform leaving the clinical and research community with one of two options: breadth with low fidelity (structured data) or high fidelity without breadth and scale (brute force abstraction of unstructured data). Our IP is a foundational breakthrough that can understand clinical context at scale and have been validated by marquee pharma and data companies.

Why You Should Join Our Team

Benjamin Franklin once said: If you would not be forgotten as soon as you are dead, either write something worth reading, or do something worth writing. — at Mendel you can do the latter. There are two things more devastating than learning that you or your loved ones have a terminal illness; getting the wrong treatment or not finding any. At Mendel, we are on a sincere mission to solve many never-solved-before technology challenges that can enable prescribers and drug makers to do their best.

We are also a fast growing Silicon Valley startup that has raised more than $20M from blue chip venture firms, with revenues more than doubling year to year, tons of benefits, on-site gym, child care, educational leaves, mentorship programs and commuter benefits.
