Behavioral Signals The Team

Driven by a passion to bring our ground-breaking patented speech-to-emotion and speech-to-behaviors technologies to market, CEO, Alex Potamianos, Chief Scientist, Shri Narayanan, and Chief Strategist Prem Natarajan founded Behavioral Signals in 2016. With the goal of enhancing and forever changing the world of business, technology is at the core of what we do. Our algorithms analyze human emotions and behaviors, transform data into usable information, and lead to making better business decisions and increasing profits.

Until now, human emotion has been considered impossible to quantify, and impossible to measure.

With our patented analytics suite, we use science to measure and interpret the “how” part of human interactions. Our solutions are easy to use and proven to help businesses improve their efficiency, reduce costs and save time.

Quite simply, our products complete the human loop by understanding calls and live interactions, measuring and interpreting their quality and providing immediate, actionable insights to decision-makers. Translating the qualitative into the quantitative. With the combined work of a strong and experienced team, Behavioral Signals is aiming for a better understanding of interpersonal conversations.
