Creative open floor layout providing the ability to interact and collaborate with anyone and everyone. The best part is having a say in the direction of the company. Unlike a large corporation, a start up gives the freedom to have your voice be heard. Transparency is great in the company, being able to understand where the financial positioning of the business is is very helpful!
Cons
Start ups have ups and downs, and you have to have the ability to grind it out when times are tough. Start ups aren't for everyone.
