Pre-Seed is the phase in which you validate your idea, build an MVP (a prototype or minimum viable product), and generate initial traction (usually using your own funds). Seed is the first major external funding round—typically PLN 500,000 to 3 million—for refining the product, acquiring the first customers, and building the team. At this stage, investors are primarily buying into the team and the potential, not just a ready-made business.
