Many high tech start‐ups fail in their first years of start‐up, which is why the reasons for their failing were identified and reduced by a format business plan design. The start‐ups failure rate was 42% within three and a half years after start‐up, and 33% for high tech start‐ups after five years. The results gathered in this project where directly implemented in a high tech start‐up, which the authors set up simultaneously to the graduation project. The project resulted in a format, designed to reduce external risks for high tech start‐ups. The high tech start‐up of the authors, based on this format, successfully joined several stimulating programs and started with the first pilot within six months.
