Who uses Mastodon?
Privacy-conscious users, open-source advocates, academics, and niche communities hosted on independent instances.
Why it matters for customer discovery
- EU tech, FOSS, and privacy communities cluster on specific instances - useful for aligned products.
- Federation means signal is fragmented; search helps catch conversations you would miss instance-by-instance.
- Smaller than Bluesky/X but often highly engaged per user for the right ICP.
Best for
- Open-source and FOSS discourse
- Privacy and EU tech communities
- Academic and nonprofit audiences
- Fediverse early adopters
Weak for
- Mass-market B2C at scale
- Single unified audience graph
- High-volume viral marketing
