'Claude Code for X growth' lands its first paying customer two days after launch

Reddit r/SaaS·low signal

The founder of Posty reports a first paying customer two days post-launch, describing the product as Claude Code for growth on X. It started as a personal tool before YC founders and investors asked for access — the increasingly common path where internal agent tooling gets productized. Single self-reported anecdote, but it illustrates how thin the gap has become between building an agent for yourself and shipping it.
