Deep Dive
1 Overview
2 History
proSapient was co-founded in 2017 by Margo Polishchuk and Jordan Shlosberg. Polishchuk came from an expert networking background and Shlosberg was a client — together they saw an opportunity to rebuild the expert network model from the ground up using AI and machine learning technology. The company raised seed funding and a $10M Series A led by Smedvig Capital, achieving rapid revenue growth and recognition as one of Europe's fastest-growing businesses.
