The bet: Teams would rather have 90% great than 100% mediocre. 53 maintained loaders beat 200+ broken ones.
SynapseKit doesn't win on every metric. It wins on principles that compound: minimal dependencies → embeddable everywhere. Async-native → production-ready at scale. Transparency → trust. Community → better code faster than VC teams. Open source → moat built on trust, not lock-in. This is the bet.
