Mr. Low GPA Ex-MBB

I very much doubt your GPA will make that much of a difference due to your successful stint at an MBB firm and your transition into venture capital. If anything, that 750 GMAT score will assure admissions staff that you can do the work. And perhaps you have an explanation for your lowish grades at HYP. If you were at Princeton, it is well known that Princeton was the lone ivy that attempted a war on grade inflation before giving it up. So if you went to Princeton, it’s worth reminding the admissions staff of that fact. If not, perhaps there is another reason to push this aside so it does not become a red flag. But as Sandy always says, admissions will blink once but not twice. And the rest of your profile is super strong. Besides, there is nothing much you can do about your undergraduate GPA except to say that this is not indicative of your academic performance due to X, Y and Z. You are a solid candidate and will definitely be interviewed at HBS.
