How can i find a really good UI/UX designer to create my web application ?

This is a typical problem with any start-up, i.e. intention to trade everything for equity. I am assuming that you're trying to trade equity for cash. In that case I would suggest you to look out for individuals with diversified skills and competencies. The reason being, less the number of individuals less the amount of equity that would be required to trade. Second option could be to look out for agencies to whom you could outsource the business process. I am not at all ashamed to mention that my own company is one such agency. However, my only piece of advice to to try and add some retainership component to your model, apart from equity, as in a long term it's easier for people to lose motivation in absence of any capital gains. The reason being, people don't understand the value of equity in startup. Rather, the time it could take for that equity to turn into something big; it may not happen as well. That's why they say there's nothing called free lunch. In my more than a decade experience working with entrepreneurs and helping them bootstrap, I have learnt that the market out there is crowded with individuals with a lust to join startup as a equity holder. In a short term, they may speak all those rosy language that may sound like coming directly from the Horse's mouth. But, in a long term you realize not everything is hunky-dory. As far as finding a co-founder or a CTO or any other executive team member is concerned, ensure that you put down the roles and responsibilities attached with each title. Apart from above, ensure that you communicate your expectation lucidly and understand the values everyone is required to bring on the table. Usual people who could be a good fit for you, apart from any agency, are people who aren't big on title. Is there anything specific you're looking at? Please feel free to revert with more clarity to receive clarity. I am just a call away. All the best!!

UserTesting can be instructive in terms of understanding whether people understand your copy, CTAs, and intended flows but generally, I've found the quality of their panels to be pretty low. You're almost always getting people who are not your actual users, so the feedback can only be generally applied as above. I find whatever web analytics package or packages you're using are generally able to provide much better insights. I also really do believe in *real* user panels. Buying pizza or offering small financial incentives to real users to click through new flows where they are talking out loud or answering specific questions is going to give far more actionable insights than anything else. What I like to do is take my best guesses as to what's not working or what I'm looking to improve and then discover/validate via real in-person customer panels. Happy to talk through this in more detail with you in a call.

I'm a feelance CFO and I work actively with early stage companies. I've been at this for almost 30 years. Some of my current and recent clients wrestle actively with this very questions. My advice is to have the tough conversations right up front, early in the team building process. This usually consists of answering questions like, "who's in charge and what does that really mean," "who gets how much of the company and when and in exchange for what," "what are you, you and you really bringing to the table in terms of skills and cash," and "who is really in a life situation that will allow them to sustain their commitment to the business?" Any team that can get through these questions can get through the trials of surviving startup. I'm happy to talk with you directly about these issues and, in particular, to help look at them through a strategic financial planning lens.

The number one would be shipping product (or anything really) out in front of a customer. If you can't work together to get something done fast, that is usually a huge indicator that somethings wrong. That usually means your values or mission aren't aligned.

I second invision for showing quick online prototypes, but for something more versatile, i use AxureRP (www.axure.com) . The ability to build a sketchy wireframe or a pixel perfect app is amazing. I love it. Great for mobile gestures and animations. Go check it out - they offer a free trial. Contact me if you want more info but they have awesome tutorials on the site. I taught myself everything.
