Company History and Business Evolution

Cleo AI was founded in 2016 by Johnny Constantinou and Paul Hagon, who recognized a gap in the market for a financial tool that wasn't just a tracker but a true assistant. The initial concept was a chatbot that would analyze bank transactions and provide witty, actionable insights. The company quickly gained traction, raising seed funding from prominent investors. In 2017, Cleo launched its public app, gaining thousands of users within months. The following year, the company expanded its team and secured Series A funding of $4.4 million led by Balderton Capital. By 2020, Cleo AI had evolved its product to include features like 'Spending Categories' and 'Savings Goals,' leveraging AI to predict cash flow and recommend savings. A major milestone came in 2021 when Cleo raised $60 million in Series C funding, valuing the company at over $500 million. This allowed for expansion into the US market and the development of premium subscription models. In 2023, Cleo AI introduced 'Cleo Plus,' a subscription service offering credit building and cashback features, further solidifying its position as a holistic financial platform. The company continues to innovate, with ongoing research into generative AI for personalized financial advice and predictive analytics for behavior change.
