At Butterfly Effect, we’re building the world’s leading community-first creative agency - helping brands grow by becoming culture, not just advertising to it. We partner with global companies to design and scale their Community Operating System: the framework that powers trust, influence, and sustainable growth. Anchored in Strategy, Execution, and Amplification, our model blends social, influence, content, and experiences into one ecosystem - turning audiences into communities and brands into cultural movements. Our belief is simple: growth doesn’t come from trying to mean something to everyone. It comes from meaning everything to a small group of people and scaling from there. This approach has been trusted by some of the world’s most ambitious brands, including Square, Formula E, Netflix, Bumble, The Cheesecake Factory, McDonald’s, WeTransfer, and Dutch Barn Vodka. Beyond campaigns, we build systems that deliver clarity, momentum, and measurable results. At our core, we believe the future belongs to brands that build with people, not just market to them. Butterfly Effect exists to make that happen.
House of Samba is my creator platform - the space where I channel my voice, ideas, and experiences beyond Butterfly Effect to collaborate with global brands and audiences. It’s where I explore keynotes, fireside chats, partnerships, workshops, coaching, and mentorship, all built around one mission: helping people and brands unlock cultural relevance and real connection. As a creator, I’ve partnered with some of the world’s most influential companies - including LinkedIn, Adobe, Apple, Typeform, Vimeo, Hootsuite, Sprout Social, Gamma, Amazon, EY, and Hotmart - to co-create campaigns, content, and experiences that spark conversation, build trust, and inspire action. Through keynotes and fireside chats, I share perspectives on culture, business, and community - creating spaces for honest dialogue and fresh ideas. These sessions are designed to cut through noise, challenge convention, and leave audiences with practical tools and cultural insights they can act on. From mentoring emerging leaders to delivering global talks and workshops, House of Samba is about connection - bringing together creativity, business, and culture to create work that resonates on a human level.
We believe progress in business, marketing, and culture is rarely limited by a lack of ambition, creativity, or effort. The real challenge comes from Bottlenecks - the unseen barriers and choke points that quietly stall momentum, waste resources, and ultimately sink even the smartest strategies. That’s why we created Bottleneck, a Sassy+ original series we co-host with Rory Sutherland, Vice Chairman of Ogilvy. Together, we blend behavioural science, creativity, and real-world experience to challenge conventional thinking, uncover why strategies fail, and share practical solutions that help leaders, marketers, and culture-shapers break through. Every two weeks, we sit down with influential voices from business, culture, behavioural science, and creativity to expose the hidden forces holding people back and explore how to turn them into opportunities for momentum and growth.
