Idea. You will be surprised, but an idea is not the basis of your project. It may not be groundbreaking, it may not be sophisticated, it may even seem outdated. Sometimes the idea to refine the previous idea is much better than the new "Perpetuum mobile".

Team. This is the core of any startup. Experienced and dedicated employees can create a unique product or service in the shortest possible time, which is especially crucial in a startup environment. It doesn't matter where your employees are. The skills, responsibility, and reasonable expenses of each employee are important.

Technology. The startup is all about technology. If you don't bring something new, you only replicate the forerunners. But even so, the main thing you have to focus on is the ultimate benefit for the user.

Methodology. The startup must be Agile. Pivots are a necessity for survival. However, a Predictive approach will be instrumental in achieving the goal. Only a combined methodology leads to success. 

Partners. The question of the founders is always a matter. It is better not to have partners if you are not completely sure about them. However, reliable partners will certainly not let you make a mistake even in the most difficult circumstances.

Funding Money is fuel for a startup. However, most investors require an MVP to get funding. Designing a working prototype is a task that requires the most cost-effective use of funds, often invested by the founders themselves.
