It is true that investors will find it a tad more difficult to reject a group once they feel like they know you. By sitting down you would appear more human, whereas standing up gives a more commercial look.
From a sales course I recently attended, the lecturer told a sequence from one of her recent trips. They were in a small town in Turkey and she and some friends had just gotten off a bus. A sorry looking man came up to her and asked, "Do you have any medicine for my head?" She was caught off guard and responded, "What?" The man points to his head and says, "My head pains, do you have any medicine?" She then understood that he was talking about painkillers and eventually got some painkillers from one of her friends and handed them to the man. With a big smile on his face, the man says, "You are very kind! Come I show you my shop."
