Slack’s San Francisco HQ is the ultimate workspace, with varied landscapes that keep employees focused and engaged as they work. Here’s how we collaborated with their team to create signage that blends seamlessly into each environment.


Slack is the collaboration hub that brings the right people, information, and tools together to get work done.

From Fortune 100 companies to corner markets, millions of people around the world use Slack to connect their teams, unify their systems, and drive their business forward.

Create signage inspired by the Pacific Crest Trail.

Slack’s San Francisco HQ is inspired by their CEO’s love for hiking and nature. Each of the ten floors is assigned a geographical theme—desert, mountains, forest—all which are found along the Pacific Crest Trail. Our challenge? Design and build a signage system that visually integrates into each terrain, providing focus and guidance along the way.

Design by committee—in the best possible way.

Our journey with Slack started with a floor-by-floor tour, allowing us to get a deep understanding of their unique environments. From there, we worked with the incredible Slack team—on their own platform—throughout every step of the process. This allowed us to quickly bounce ideas back and forth between project managers, designers, and contractors, ensuring smooth sailing from beginning to end of each project.

Signage that encourages curiosity, exploration, and storytelling.

The most rewarding part of the process? Seeing reactions from the audiences we designed for. Visitors were greeted with a lobby sign that piqued curiosity and encouraged exploration. Department signage made teams proud of their contribution and space within the office. We even worked with their team to create meaningful signage that touched on the company origins for the CEO and the founding team—establishing their legacy and giving them stories to tell.

A huge thanks to Danee Chavez, Kristy Tillman, Lionel Brazil, and the Slack team for welcoming us into your beautiful space and trusting us with your brand. The ease of communication between our teams with every project is a true testament to your commitment in connecting teams around the world.
