Problem
Developers must constantly learn new technologies, but:
- Courses/tutorials are too long (30min~2hr)
- Documentation makes it hard to find just the key points
- Learned content is quickly forgotten (Ebbinghaus forgetting curve)
- Hard to secure learning time at work
Pain Intensity: 7/10 - Continuous learning pressure with time constraints
Market
- Primary Market: Developers worldwide (~27M)
- Segment: Junior to senior developers, tech teams
- TAM: Microlearning market $3.83B in 2026 → $8.64B by 2032 (CAGR 14.35%)
- SAM: Developer education segment ~$500M
