About Us
I’m Madeleine, the founder of Square Circle. After graduating from Oxford, I began my career in startup marketing, as an early employee of a unicorn tech company.
I and my small team now help B2C brands scale up their customer acquisition using scroll-stopping social media content (finally, I’ve found a good reason to use social media 😝)
