Projects that work on a product in any phase of the market and are ready for long-term development will definitely survive!
Not all projects can survive although they have good products, it depends on the quality of the team as well. Most projects only focus on the products without thinking deeply about the quality of their team members. In many cases, the projects failed to survive because of the lack quality of the project team members.
You won't believe it, but many projects could not survive for just another reason-because of weak marketing... they had a team, a product, but they could not present themselves to the community, because in many ways they were great specialists in their own field, but not in business.
