AI · London, United Kingdom · Founded 2015

AI-powered unified customer feedback analytics platform MoreLess

Chattermill is a customer experience intelligence platform that utilizes artificial intelligence to help businesses understand and act on customer feedback. Founded in 2015 by Mikhail Dubov and Dmitry Isupov, the London-based company was born from their frustration with the slow and expensive nature of traditional customer research. Isupov's experience manually analyzing customer feedback at a market research company highlighted the potential for AI to automate and scale the process of extracting valuable insights from unstructured data.

The company's core offering is a platform that unifies customer feedback from a multitude of sources, including surveys, reviews, social media, support tickets, and chat conversations. It then employs deep learning AI to analyze this data in real-time, identifying key themes, sentiment, and actionable insights. This allows organizations to move beyond manual analysis and gain a comprehensive view of the customer experience, linking feedback directly to business metrics like Net Promoter Score (NPS) and customer satisfaction (CSAT). A key differentiator is the platform's ability to interpret nuanced feedback, such as multiple sentiments within a single comment.

Chattermill operates on a software-as-a-service (SaaS) business model, serving a global client base of predominantly enterprise-level B2C companies across various sectors, including e-commerce, finance, and travel. Its clientele includes major brands like Amazon, Uber, HelloFresh, H&M, and Zappos. The company has demonstrated significant growth, securing a $26 million Series B funding round in December 2022, bringing its total funding to over $40 million. This capital is aimed at supporting expansion in the U.S. and Europe. In late 2023, Chattermill launched 'Copilot,' a generative AI solution designed to provide a more conversational interface for users to query their customer data.
