Not a single mention about what it is you want feedback on then how do you expect a meaningful feedback, maybe if members have a clue on what you are working on then they can give their opinions base on what they understand, or that's what the calendar is for! Probably am not getting it right.
Its better to tell directly rather than setting up some meetings on a specific date that you had given.Unless if you do put up some sort of amount or bounties
about their own feedbacks then you might able to hook up some people who would give out their own views.Why would need to pay if you can get it for free?
Just mention or do show some glimpse of the project you do work and we would give out the most honest insight that we could.
You should be transparent you never mention what kind of project you are working, we don't have any idea, we like you to post it here, since this is not an ICO, we are going to welcome if this is something and can bring something to the community to use, that would be great, instead of contacting you, it's better that people can read the reviews here this is also a good way to promote your project.
You are looking for feedback but didn't mention what you are talking about?

Why anyone should meet you? You are looking for partners for your startup.
Make the things clear to proceed further.

that calendar is for the people that want to schedule a meeting with here.
But before that it will be good for the OP to explain what is the topic that you will discuss later
Hey guys!

Thank you so much for replying to me!
Actually, our first idea was to build a superfast cryptocurrency exchange platform. We still in the pre-registration phase
https://www.binaryx.com/ and plan to launch it in the next 1.5 - 2 months. A little bit later, after the long research we realized that we need to release some unique features to build a competitive advantage to find the proper PMF due to high volume of competitors. So, our team came up with the idea to build a marketplace of crypto traders based on our cryptocurrency exchange platform. It would be nice to hear from you some thoughts and feedback about this idea of a marketplace of crypto traders.
Thanks and BR,
Anastasia
