Mocking the competition and not respecting them can make a founder look naive to VCs.
Hiding core issues during fundraising, such as not having a CTO or previous funding, reflects naivety to VCs.
Believing they can achieve significant success with a small team or minimal funding is seen as naive by VCs, unless there are exceptional circumstances.
Arrogance is a trait that never plays well with VCs, although a little is sometimes acceptable from a top CTO.
