I think that it is impossible! Because, to do a delivery business, logistic centers are needed. However, it can be difficult for a 'second mover' to have the centers. Take a look at recent situation! Coupang and Market Kurley are dominating the whole country's delivery marhet. Delivery services are already saturated! For this reason, it is too late for anyone to start a delivery business. Due to Corona, the delivery service business is becoming popular. On the other side, except for the two, Baemin, Yogio, Baedaltong, to name a few, are sharing the market, If I were you, I would look for another business. Last weekend, I read a book, it included three items. Though I can't tell you about that, there is something that the three have in common. It was related to the 'Sanitation Society'. They were all tech-startup firms. To do a business, technology is very important! It can make the business sustainable! I wanna tell you about startup business. The three most important things are team, item and technology!
