For that particular company, I would look at an LLC. Mainly due to the liability they have if something goes wrong. I don’t believe that they have enough revenue to cover a lawsuit and continue to function as a company proficiently afterwards. If over the next 5 years they project 80-100 % increases in revenue each year, I would look at incorporation. This is because the company will have the option of going public. Going public will give them more leeway to explode their business.
