The brand book
The brand book
that builds with you.
that builds with you.
We’re evolving the brand book. Our intelligent guidelines plug directly into the tools and agents your team already uses. Your brand no longer lives on a page—it actively shapes every piece of work as it's being made. Teams move faster, output gets tighter, and nothing ships off-brand.
We’re experts in building brands with meaningful presence. Brands engineered for the retail shelf and optimized for the scroll.

“I’m so grateful for the vital work your team did to help us get these brands back on track. Ulta was wowed by the new equity on Hot Tools—from the fresh take on packaging to the glow up on social. Target gave their blessing to the new Gold n Hot approach. When the larger Helen of Troy family got a glimpse into the Revlon work, and were stopping me in the halls after to share their excitement.”
Lynne Hammell
VP of Marketing, Retail Beauty, Helen of Troy
“Our refreshed brand and personality has been so well received! We’ve also seen an increase in traffic and memberships. We couldn't ask for better results.”
