In his work with founders and their teams, Alex brings with him some wisdom imparted to him by his father. “My dad taught me a couple of things that I find valuable in business and in life: tell people the truth, always do the right thing, the customer is always right, and do it right the first time.”

As a trained research scientist, Alex breaks down business problems with deductive logic and analytical rigor. He originally studied physics at Harvard College, where he graduated summa cum laude, and then went on to receive a Master’s degree in materials engineering from MIT, where he was part of a research group building the first fully optical computer chip. Alex also received an MBA from Harvard Business School, where he was a Baker Scholar, an honor given to the top 5% of the graduating class.
