1 - This is some sort of a marketplace where you can buy and sell expertise. Kinda like a Air bnb for odd jobs. Reminds me of a similar startup that tried that, but I cannot remember their name.
2 - The landing page's layout is a little confusing. I clicked on a couple of links and landed on your about page[1]. When you have a 90 second video explaining what your product is, why would you not put that on a landing page ? The call to action would be very easy for me. Click on the video and know more about you.
3 - Although you meant for people to click sign-in on the landing page, that action was not very obvious to me. You should look to prioritize 'Sign-up' not sign in. The fact that they are both green buttons that look alike does not help.
4 - Your key customer sign-up categories appear to be a buyer who gets services and a seller who markets his / her services. You might want to streamline signups to reflect that.
5 - The text overlay on the image is not very visible / readable. Have you considered switching the images to color on mouse-over ?
6 - Where is the submit button for 'Suggest a feature' under watercooler ?
7 - I don't quite get the watercooler part. Is it meant for users to share insights and that becomes part of the news ?
8 - What is your pricing ? Where can I see what cut you take and what I get in return ? What are people signing up for ?
9 - When I sign up, its not very clear to me that something happened on the screen. Its great that I am logged in, but the UI needs to do more to inform me about what just happened.
10 - A short tutorial on signing up would be great. The app asked me to add funds and I don't understand what for.
I like the idea. The presentation and the user flow could use a little work. Gather the feedback you get here and fine tune your site. Nice work.
