Case StudyStarknet BTCFi Campaign
Castle Labs ran the end-to-end KOL campaign for Starknet Foundation's BTCFi launch. Narrative strategy, creator coordination, and delivery tracking across a 6-month window.
September 2025 to March 2026 | Ongoing Engagement
The Brief
Starknet needed coordinated creator distribution for a major ecosystem push. Not a one-off campaign, but a standing network they could activate on any timeline, without rebuilding outreach from scratch for every announcement. Castle served as their external KOL arm: a single point of contact handling everything from creator relationships to final delivery.
They built. We executed.
What We Did
- Managed and coordinated a roster of 34 vetted crypto KOLs across global and Korean markets
- Translated campaign objectives into creator-ready briefs aligned to each narrative moment
- Matched KOLs to each initiative based on audience fit, content format, and topic relevance
- Coordinated publishing around official announcements and ecosystem milestones
- Tracked deliverables in real-time with zero internal overhead for Starknet
- 8 content formats: threads, posts, long-form, videos, X Spaces, newsletters, retweets, shorts
