I'm just about to start in a new job. At the same time I'm currently working with a co-founder on weekends on a startup idea. However it's still early stage without funding or customers. However, we are applying for incubators and accelerators. Chances are I may quit in another 3-6 months to go full-time on our startup idea.
I haven't disclosed this to my new employer (digital web agency), that I'm doing this as I think it would have compromised my chances of landing this job. My role in this new job has nothing to do with the startup idea, so I don't think there's a conflict of interest of any sort.
Should I disclose my project or am I correct in keeping it under the wraps for now?
