In the real world investments in companies worth $10 - $20million implies that the company is big. Then again its' not about the number of employees, but the quality of the employees executing the project and then ultimately, the product which is what people are investing on. In the cryptoworld unfortunately, we mostly invest in ideas, which is why a lot people insist on seeing a working product before investing in any ICO.
The crypto market is so unpredictable. You don't need numerous team members to believe in a project. You just need to read about the reputation of the team members. Similarly, you can also check the track record of the team behind a particular project.
