Full Reasoning
Builders can learn from LetterGator's focus on a niche often overlooked: future message delivery. Integrating Arweave for permanent, decentralized storage creates a strong moat. Its pricing strategy — a free tier for short-term use and usage-based for long-term storage — lowers entry barriers while monetizing core value. This blend of technical integration and trust in permanent storage is difficult to replicate.
