Her story is a bit inconsistent here. She says that she e-mailed pitch decks from her e-mail and then sent the same message from her husband's account. Of the two responses she mentions one asked for her pitch deck and the other only responded after a Linked In message. So it doesn't seem like she was sending the same message and/or she was sending messages to people that her husband had a prior relationship with.
I downloaded the app and it's nothing special. It also looks like they bought a bunch of fake 5 star reviews at the end of January. There's nothing exciting there and nothing about her background that would lead anyone to believe that she would be a successful founder. Her pitch deserves to be binned and the only reason that it wouldn't would be because of some personal connection her husband had.
