1. The business revenue model is weak. It can't generate revenue. Even minimal revenue which they generate is not sustainable in longer run.
2. They call themselves an e-commerce firm but every transaction happens offline.
3. Construction industry is the most corrupt and its impossible to streamline with mSupply line of business.
4. Its neither a full-fledged technology nor a marketplace nor a service provider.
5. They have hired people at all levels without any clarity. Now firing left right center that almost every employee has no clue whether he/she would survive the next month. Situation is the same if you are a Business Head or a Vice President.

7. Even IIM grads waste time mostly in FB, whatsapp, glancing newspapers etc
8. Its a startup, agreed. But it can't change the rule everyday.
9. Finally, its the least to say now. As the business model is weak, few employees took advantage of it leading to unethical practices and integrity issues.
