In 2008, performance marketing was becoming increasingly fragmented. Ad networks were taking credit for conversions they didn’t fully drive, and most agencies were optimizing media against network-reported numbers and calling it performance. We didn’t trust those numbers. So we created our own measurement layer. What began as internal infrastructure evolved into Atrilyx — built on patented attribution technology, powered by Ai that connects channels, devices, and conversions into one reconciled source of truth. Every media decision we make runs through it. Every client engagement benefits from it. Nearly two decades and more than $1B in managed media decisions later, the problem still exists. The networks still grade their own homework. We still don’t let them.

The Brand Experience is the Brand
Starfish is a Brand and Creative Agency, with unique expertise in Brand Experience. Since 2002 we have built brands on a single durable conviction: a brand is not what an organization says, it is the sum of every experience it creates and its customers encounter. The Brand Experience is the Brand. Headquartered in New York, with offices in Paris and Boca Raton, we build brands that work identically in the human world and the AI world. Our work is guided by BCI™ (Brand and Creative Intelligence™), the methodology we use to articulate, design and activate brands across both. Where AI enters our production it is human-led, because the judgment about what a brand should mean, and what it should refuse, stays with people. We have delivered that work for clients including PwC, Gallup, Dunkin', ADL, Baxter, Avis, Principal, Samsung, Hologic and CRISIL (S&P Global), alongside hundreds of other organizations that lead their markets. We practice across four expertise areas. Brand Experience is the discipline of designing every touchpoint as part of one integrated brand. Brand Soul is the emotional resonance a brand creates, which only people can architect. Brand Coherence is the consistency of brand expression across every channel and mode of interaction in which the brand operates. Brand Intelligence is the practice of building brands that are compelling to people and interpretable, discoverable and authoritative to AI systems. Recognition: 12 Transform Awards wins in 2025, and six shortlistings in 2026, judged by an independent panel against named competitors.
