AI SaaS validation help - I will not promote

Hey everyone so I created an AI assistant app that is actually top tier quality on the frontier agentic harness level of quality with 45 users within the first 2 weeks without any marketing only word of mouth. Still working on setting up subscriptions etc. But the AI agent pretty much replaces 80% of busywork for teams, general users, businesses etc. and can automate mostly anything online besides things that require explicitly a human. At what point is the idea validated enough to know I’m on the right pat
