SEPH LANG – DESIGN STRATEGIST+ PRODUCT CREATOR
Product.
Design.
Strategy.
MY APPROACH
I anchor on first principles, find the structural problem, and build solutions from 0 to something real.
I'm a design strategist and product creator with roots in human-centered design and a decade of experience building solutions for complex challenges at scale. I started at IDEO.org leading projects across agriculture, health, and financial inclusion globally, then spent six years at Indigo Ag as the sole designer for their full sustainability platform. I work best as an athlete rather than a position player; I move comfortably between design strategy, upstream systems thinking, user research, and execution.

HOW I WORK
An HCD-rooted process accelerated by AI
The core phases of human-centered design haven't changed — but AI has fundamentally compressed the inner loop between insight and prototype. What once took weeks now takes hours.
From Field-by-Field Entry to Crop-Oriented Program Execution
Redesigned the foundational data model of Indigo's carbon platform to match how growers actually manage land — reducing burden and unlocking scale.

Designing Carbon Software Around Grower Behavior Change
Synthesized qualitative research across 120+ stakeholders into a behavior-change framework that reoriented Indigo's software strategy around adoption, trust, and seasonal decision-making.
