Im assuming solid profitable means a team of employees which makes sense. It takes years to build a solid team with dedicated roles as well as build the infrastructure so it can run smoothly. The first few years you’re still finding your footing in the market and figuring out how many sales people and managers you need.

Ive built solid profitable businesses in a day before but they don’t require employees or any infrastructure. You can build an app, place it on a market and sit back watching the profits roll in, but that’s not the old school business.
