Role

Sole Product & Brand Designer

Collaborators

Jerome Pesenti (CEO)

Sizzle Founding Team

Duration

2023-2025

Alongside defining product, I also worked on defining the Sizzle Brand. Most AI learning tools promise speed and instant answers. We wanted Sizzle to take on a different approach. Inspired by Dr. Becky on The Learning Space, the identity is built on the simple truth: learning can be frustrating and that frustration is resilience forming in real time. Sizzle, the mascot, is a playful embodiment of sustained effort and the choice to stay when it would be easier to quit.

Color

The color system pairs bold, high-energy hues with thoughtful neutrals, allowing the brand to feel expressive in marketing while remaining legible and scalable in product.

Visual Language

The illustration system consists of a set of characters that represent the emotional arc of learning. Woven throughout the product, they add touches of joy, and can evolve into stickers that celebrate student milestones and small wins.

Product & Marketing

Designed every screen and state of the Sizzle app as well as other experience touch-points across the service in lock-step with engineering, growth, and marketing.
