It's red flag. I asked the same question of one startup and was told that i didn't need to know the answer.
Fast forward 10 years ... The company tried to go public and they had to do a 5760 to 1 REVERSE split to shore up their share price. People who naively thought they had 100k shares ended up w less than 20. Thecompany had to cancel the planned ipo, too.
And that is why refusing to share information is a bad idea. They lost a (presumably) good hire who might have made a difference to the outcome of their company. They wanted to hire but chose secrecy over a new employee. It didn't work out well.
