Spark

Crypto Savings for Everyone

We designed the complete product suite for Spark.

From a retention-focused airdrop flow to a savings interface that scaled to billions in deposits, we built a system where complex DeFi feels simple and works smoothly.

Problem solvers with aesthetic superpowers. We make your users say "damn, that's good" without knowing why. Strategic minds, artistic souls, and zero tolerance for mediocrity.

SPK Token

Complete Spark Token Experience

We designed SPK's complete token experience: airdrop, staking, governance, and points.

Design System

Building Trust at Scale
