On a another note, I have to say one that really stands out to me is True Link. The old-people credit card, my grandad has almost fallen for online scams before and I think all would happily get our grandparents this peace of mind. Brilliant idea that one.
In fact, the worry I have is that they will pigeon-hole themselves into being a product for old people. When they go to expand to other markets (which according to their demo day pitch they will be), they may run into brand issues. No one, not kids, 20 somethings, or middle-aged people, want to feel old or be associated with anything that might make them feel that way (have you ever heard or seen someone rant about receiving an AARP letter in the mail?).
Going 100% after the elderly market makes plenty of sense, though, for the future. There already are under-18 products, and elderly are kind of a unique market -- you don't want your parents/grandparents to be scammed, but they have every right to spend their money however they wish (since it's their money), unlike under-18 where it's usually money from parents.
This is a minor nitpick and/or question. The sample conversation shown on the iPhone screen is in blue which indicates it's an iMessage conversation. Not a big deal, but it was a red flag to me because it meant I wasn't looking at a real screenshot of the product in action, but rather I was looking at promo material and I'm not sure how much of the product actually exists right now vs how much is a concept that is still being built.
