What is the best startup 🦄/company you ever worked on?

Hey, I would like to bring up the conversation about awesome startup(s) or companies including there pros and cons. What is your selling point to work for others? Maybe your owner of a startup - what is your story? (... salary, company values, great people, location ... ) Your welcome to share and reference some epic workplaces or other cool views. I am creating a project about making a nice offline and online space to work and live in Seoul, South Korea. The mindset to enable a better everyday life at work. Yes, your suggestions would be really helpful, thank you!
