The document discusses characteristics of successful tech startups in Vietnam. It finds that on average, founders of successful startups were older at 28.8 years when starting their first successful company. They tended to gain experience through multiple jobs and startups before striking out on their own. Many had international exposure through work or study overseas. Successful founders also customized proven business models from other countries and were relentless, treating their startups like a marathon rather than a sprint by spending over 5 years on average building their companies. The document advises emulating these factors or being exceptional in other ways, but emphasizes taking action to actually start and build a company.
