< Day 3 — Complete >
What Would They Really Want?
Design as communication. Teams found reference designs, extracted design systems with Claude, and built apps that looked intentional. Guest: Brittany Sigler on product thinking.
What Happened
Brittany Sigler's session on product thinking and individualization at scale gave students a new lens on their work. The afternoon builds showed dramatic personality shifts — same features, completely different feel. The design guidelines PRD layer proved its worth.
Key Moments
- Brittany's talk on individualization at scale shifted how teams thought about their users
- Same features, completely different personality — the design comparison landed
- Students discovered Mobbin and Dribbble as design reference sources
Student Highlights
“Adding a color palette and font choice made the app feel like it belonged to someone.”
— Farah
Learning Targets (as planned)
Knowledge
- Detailed feature behavior specification
- What features need under the hood — databases, APIs, user accounts
- Product thinking for non-product founders
Skills
- Writing feature specs that AI builders can interpret
- Identifying “reach” features vs. core features
- Using Claude to reverse-engineer features from reference apps
Mindset
- Write it down — Claude might know how
- Ambitious is okay if the PRD is clear
