As Seed expanded beyond a DTC category leader, we needed an identity that could grow with us. One that could move into new products, new health areas, new spaces, and new cultural moments—without losing what has always defined Seed: deep scientific rigor, expressed with human clarity.

This work goes far beyond a refresh. It’s flexible, living, grounded in science, and designed to scale. Every element is informed by how life actually works. From a refined wordmark, inspired by Eames’ Powers of Ten, to a color palette rooted in Darwin-era taxonomy, to a bespoke typeface and motion language shaped by real microbial behavior.

Around this, we’ve built anatomical renders, iconography, illustrations, CGI, human-centered imagery—along with systems, templates, modules and components—to help you to see, feel, and awaken to the power of the microbiome.


Seed is a brand that does more than represent the science of the microbiome—it makes the invisible undeniable.













I was part of the core working Seed team behind the brand’s identity refresh. I worked to translate the brand identity into internal design systems to bridge the work Mouthwash Studios created spanning art direction, brand guidelines, and figma systems.





Email Design System
With Seed’s new brand identity, a refreshed email design system was created, one that was scalable, modular, and uniquely Seed. I led the design direction from defining the overall look and feel to building out a full design system on Figma. 



During my time at Seed, I led email creative for the brand’s Sustainable Refill Program, or SRP for short, as part of the retention customer journey. To scale monthly retention emails, I built a sub-design system that operated within the larger email design system, focused on a dedicated program name lockup, sustainability modules, and SRP plan modules.
