CraftOS is developing advanced AI agents to help businesses run their operations after they have built their product. It has never been easier to launch an MVP. But once the product is ready to scale, many founders (solo entrepreneurs and small teams) get bogged down by the day-to-day grind of running the company.
We want to provide them with AI agents that help founders operate their startups, making intelligent decisions and automating the process of building and running a business.
