Other than the obvious ethical issues about doing that I would think that you would open yourself to a lawsuit from your employer.
You have a fiduciary duty to work in your employer’s best interests, that means not moonlighting in competition to him or poaching his clients after you leave.
This law suit would not be against your company that you would start up, but would be against you personally. You could lose all your assets.
Even if you win the lawsuit, the costs of defending yourself could bankrupt you.
Then you would have a fight to keep your PE status and the means of starting over.
Quit your former company and do not use the contact list provided by that company. You can of course look up the same information after you leave and contact people that you have a personal connection with but I’d wait a reasonable interval before I actively approached clients that I was involved with before leaving, start with the clients not currently active with your former employer.
Of course, this is only an off the cuff opinion and I’d advise you to get some legal advice, no matter which side of the question you are on right now.
