Closing
Each investment stage is not merely a difference in the amount of capital raised — it reflects different hypotheses to be validated and milestones to be achieved. Raising excessive capital too early leads to unnecessary equity dilutionDilution
The reduction of existing shareholders' ownership percentage due to new share issuance. and reduces product development flexibility due to pressure to deploy funds.
In the Korean market, the Pre-Series A stage is particularly robust, and the strategy of achieving sufficient validation at this stage before attempting Series A improves the success rate. Regardless of the stage, the most important thing is to be prepared with a clear answer to the question investors will always ask: "What will this money prove?"
