Phil Rosenthal

Phil Rosenthal is president, chairman, and a co-founder of Fastcase, an online legal research software company based in Washington, D.C. Fastcase brings big data analytics to legal research and currently serves 800,000 attorneys with the number one legal app according to the American Bar Association.

After graduating salutatorian from Bronx High School of Science, Rosenthal attended Yale, where he majored in physics and graduated summa cum laude and phi beta kappa. He then went to Caltech, where he earned his doctorate in physics, researching string theory and cosmology and also working at the Jet Propulsion Laboratory, where he worked on the mission that eventually flew by Pluto.

From there, Rosenthal went to Harvard Law School, where he graduated magna cum laude, and then to the law firm of Covington & Burling in Washington, where he concentrated in patent, nuclear and telecommunications law. There he met Ed Walters and together they founded Fastcase as an alternative to Westlaw and LexisNexis.

Rosenthal is currently running for Congress in New York’s 10th Congressional District against Democrat Jerrold Nadler.
