We always hear the word "Startup" in everyday life. Everywhere people talk about business, everywhere online they discuss how to sell. Although Vietnam is a fertile land for startups to flourish, there are still challenges that threaten their survival. An expanding market means fierce competition, even though we know "hundreds of sellers, ten thousand buyers" but "ten people doing business is not as good as one person doing business". Turning the dream of starting a business into reality is not simple, but achieving success is even more difficult.
