From a quick look at the projects and ideas you currently have, it appears to me that this is a really slow way to go about building products and may even lead people down the wrong path. Couple of things stood out for me:
Spending days on logo design and "testing" - you really can't afford to do that. It is better instead to build something and put it out. You can get 10 people to use a bad product, but literally no one will use your logo. This must be against lean, no?
Testing assumptions such as "People are comfortable dating within their extended friend group" - that's taking things too far. It's good to be skeptical of one's beliefs but you can't completely throw gut feeling and common sense out the window.
Doing such things may give one the illusion of progress but it is a waste of time.
I'm also wondering who the project founders test their assumptions with. If it's not with the intended users of the final product, then it's worthless.
Everyone loves giving product advice (hi!), but you can safely ignore most of it if their answer to the question, "Will you use this?" is No.
Making new products is hard. But you can't change that by asking everything to the users. You do have to trust your gut and build stuff. Regardless of what people say, their actions don't follow.
Making decisions with more than 75% of the information is by definition hesitation. - Josh James
