Stealth Company
Finance/Trading SaaS (software platform included) and community business with tons of paying subscribers. Very lean margins at the moment as there are no employees and only about $100-$300/mo in expenses. Acquisition would include full software ownership rights, all custom bots/tooling, all educational resources and full customer base. Easy owner transition via Whop. I'm willing to provide up to 2 month's of free post-buyer support and be active within the community as you grow/expand it.
