Please share your experience of building startup(project) from beginning. What was the hardest or most common problems you've encountered? etc...
From my experience, the most important part at the beginning is the team. You must find partners that are hardworking, goal oriented and believe in the project. Also, they must respect each different opinion and know how to deal with the differences. Since the start, the duties and responsibilities should be well defined and a process on how the decisions should be made, considering different topics, must be clearly disclosed to the team. As soon as you achieve that and every single person in your team is well aligned with your strategies, you will be more prepared to deal with your laments and glories. After you establish this direction, you will be able to use your funds smartly. However, if you don't organize the most important part of a company, the people, you may displease people without noticing ending up compromising dedication.
Of course running a project with lack of funds may be a problem, but when a team truly believes in the goals it can overcome such challenges. "Fail and fail again, then, succeed".
