The story is essentially what you seem to be doing. A man (who lives in India) joins a company that sells computers, and he does something that they deem wrong and he gets mocked and humiliated for it by his boss and coworkers. He is quite upset about it and, wanting to be successful, he starts his own company by secretly working with employees that don't like the original company's policies, and they branch off and become successful while using the resources of the offices they have with their old job, which they still work for but are doing it behind everyone's back since what they are doing is illegal. Although the movie is in Indian and requires subtitles, it's quite entertaining, and you can get it on instant que on Netflix.
