In early 2024, three founders launched CastMagic, an AI tool that repurposes video and audio content into written formats like show notes and social posts. Ten months later, they were doing $120,000 in monthly recurring revenue. They built the first version in two weeks, launched on AppSumo for $350,000 in lifetime deal revenue, and grew to over 10,000 paying users without venture capital. The founders—Ramon, Blaine, and Justin—came from VC-backed startups and deliberately chose a different path this time.
