Hesaam Esfandyarpour
Founder and CEO of Genapsys
Hesaam is the Founder and CEO of GenapSys Inc. He is an inventor of electronic DNA sequencing, a technology he developed during his PhD work at Stanford. Hesaam has dedicated the past decade of his life to the development of this novel DNA sequencing technology, which has at its core the convergence of multiple fields of science – engineering, chemistry, biology, and computing. Hesaam incubated the technology at the Stanford Genome Technology Center for a period of six years before securing licenses to the IP and incorporating GenapSys in January of 2010. He has grown GenapSys from just a handful of employees working out of Menlo Labs incubator space, to over 50 employees across seven functional teams. In 2012, Hesaam partnered GenapSys with StartX, an accelerator for the development of Stanford’s top entrepreneurs. He has raised approximately $50M for GenapSys in Seed, Series A, and Series B rounds of financing. Hesaam holds a PhD and MS in Electrical Engineering, and MSc Management degree, all from Stanford University. He earned his BS in Electrical Engineering with Honors from Sharif University of Technology in Tehran, Iran. When he is not at GenapSys HQ (which is rare!) you can find Hesaam spending time outdoors, hiking or spending time with family and friends. He is also a great lover of poetry, his favorite of which are poems by the Persian poet Saa’di.

Tim Sweeney
Co-Founder & CEO of Inflammatix
Tim Sweeney, MD, PhD is the co-Founder & CEO of Inflammatix, Inc., which focuses on using robust informatics and machine learning to derive novel HostDx™ diagnostics based on ‘reading’ patterns in the immune system. Inflammatix’s first tests are focused on diagnosing acute bacterial and viral infections and sepsis. The company is funded by Khosla Ventures, Stanford-StartX Fund and the U.S. government’s DARPA program. Tim Sweeney completed his MD and PhD at Duke University, after which he was a surgery resident at Stanford. While training as a surgeon, he became frustrated with the limitations of current diagnostic tools for infection. During his residency, he completed a postdoctorate MS in Biomedical Informatics, mentored by Dr. Purvesh Khatri. Together they designed the custom informatics algorithms for sifting through heterogeneous ‘big data,’ which formed the core technology on which Inflammatix is based.
