Cleo. Where AI meets money. Cleo launched in 2016 by people who have been burned by banks. Fed up with the broken system, we decided it was time to make a change. Since then, the cost of living has skyrocketed, the rich have continued getting richer, and our vision has only become clearer. Our mission? To change the world's relationship with money. Cleo is a platform for the 99% – an AI assistant defining a new category, one that goes beyond saving and budgets to actually changing how we feel about our finances. Using simplicity and humor, she’s helped millions of people improve their relationship with money, because we believe that everyone has the potential to achieve financial well-being in just one generation. Through a personalized chat, she provides you with deep insight about your money and tailored financial tools that increase your ability to save, all while making you laugh. We’re a product for the next generation. That means that we are committed to inclusive and unbiased financial growth for all. It also means dropping the BS. In the past year or so we’ve grown the Cleo team from 100 to 250+, and closed a $80m Series C led by Sofina (that’s a $500M valuation). Want to get involved? You know that awful feeling when you wake up wondering if what you’re about to do for the next 8 hours actually matters? That doesn’t happen here much. Everything we do is grounded in purpose. And because we’re all showing up for the same reason, collaboration comes easy. We have a culture of stepping up. We want, and expect you to grow and develop. You’ll have our support in everything you do. But more importantly, you’ll have our trust. We treat our people as humans first, employees second, which means giving everyone a voice. All perspectives are embraced here.

Our Tech Stack Cleo is built as a Ruby on Rails monolith with a single React Native app frontend, utilising TypeScript. We also leverage Python for machine learning services and PostgreSQL for our database, all hosted on AWS. Our CI/CD pipeline is fully automated, with production deployments happening on every merge via Heroku. Our backend engineers deploy multiple times a week, and we release our frontend app to Google and Apple for review at least once a week.
While we take a pragmatic approach, we place a strong emphasis on quality. Our code is peer-reviewed, and we maintain automated testing using Minitest and CircleCI. We're also actively working towards a more modular architecture, focusing on separating concerns to achieve all the benefits of microservices within a monolith, while progressively refactoring our code as we build new features. Everyone in the engineering team contributes to driving our technical strategy, voices & ideas from all levels are valued: we are all owners at Cleo.

UK App access: The Cleo app is no longer downloadable in the UK. If you’re an existing user, you’ll still have access to the app. But some features won’t be available. Why? 99% of our users are based in the US – where financial health is often overlooked. We’ve decided to shift our focus to where we can provide the most value and make the greatest impact for users who need it most. Then we’ll be able to apply what we learn to better support our UK users in the future.
