Reason for selling
I built MUMU with a lot of love, but I'm a student from Bangladesh and currently working on my main startup RoamRoles (a job search platform). I can't give enough time to grow MUMU. MUMU has great potential and already has 500+ beta users who love it. I want someone who has more time and marketing experience to take it to the next level. I will provide full support to the new owner for 1 month. Reason: Focusing on other project & studies.
