✨Who we are

Co-founded by Mikhail Dubov and Dmitry Isupov in 2015 while at Entrepreneur First, Chattermill was born out of their frustration that it took weeks, sometimes months, for customer research to yield any quality insights. Often, these would be out of date by the time they reached decision-makers. And it was also financially out of reach for most companies.

When they started what eventually became Chattermill, they had a hunch that they could use the newly available tech of deep learning to help companies find insights amidst messy data. Their vision was to take what agencies and cutting-edge brands were doing by hand and automate it.

Today, our Unified Customer Intelligence platform is used by the world’s best-loved customer-centric companies, including Uber, HelloFresh, Wise, and more, all of whom can now see and act on their customer reality.

Our Mission & Vision

• Our mission is to empower teams to see their customer reality
• Our vision is to analyse over a billion pieces of customer feedback by 2027
