Even if you are an early stage company, you've still got to have something resembling the concept of a balance sheet, even if it's an excel spreadsheet with a list of two computers, a bank account, and an AWS bill that hasn't been paid yet. Maybe he's right that he personally has never read a balance sheet, but for literally any company that has already formed before the investment, they would be extremely foolish to overlook it.
I've personally seen A-rounds fall through because of balance sheets...turns out that when you promise hundreds of thousands of dollars in future services in exchange for a little bit of present cash flow, it can drastically affect your balance sheet and prospects for future investment.
