That still doesn't answer why you need to raise VC money. How does VC money add value to a company which already has an "enterprise" solution and is a known brand to almost all Fortune 500 companies? GitHub is already making a lot of money via cash flow and VC money will only make them beholden to outside interests. Stack Overflow tried to spin why they were raising money after spending years railing against VC-backed ventures. This seems to be a similar scenario.
