What counts as genuine traction short of paying customers?

Yep. Although I don't think that's limited to MVPs. It's just always the case. You can copy code, features, etc. but you can't copy soul. There will always be people who copy you. It's better to keep moving forward and accept the copy cats than it would be to try and shield yourself. Keep an eye on the copy cats. But in the long run, if you're authentic and worthy, you will beat them.

I do not believe you should incorporate your company yet as there is a chance you will scrap the idea or iterate on the assumptions after analysis. I suggest you run your initial testing on a very minimal MVP to see if there is interest. I would go further in saying that you should not even allow people to pay only have them click on the payment option because at that point you know that it would be a conversion. The ONLY thing you are proving with an MVP is validation of an idea. Only make the mousetrap front end and see if you can drive users to where you want and stop. Even if you frustrate some people, it was worth it as you now know for sure people will buy or do what it is you wanted. Schedule a call with me to find out more. God knows I have done this enough times. Good luck Josh

You always want to mitigate risk, for you and for investors, or partners. One of the easiest ways is creating fake landing pages of your product idea. You then run ads, fb or Google, and see if people 'convert'. Convert can be giving their email, clicking a button like buy now, faking all the way to checkout, whatever you think proves there is a market and need for a solution of your product. There are many other ways to test a product without building. I would suggest you pick up the book Lean Startup by Eric Ries, as he is the founder and master of the MVP, minimum viable product. If you have any questions, feel free to reach out as I was in a similar situation with my venture and in the EdTech space.

Whoa, start by reading the Lean book again; you're questions suggest you are making a classical mistake made by too many entrepreneurs who live and breath Lean Startup. An MVP is not the least you can show someone to evaluate whether or not building it is a good idea; an MVP is, by it's very definition, the Minimum Viable Product - not less than that. What is the minimum viable version of a professional collaboration network in which users create a professional profile visible to others? A website on which users can register, have a profile, and in some way collaborate with others: via QA, chat, content, etc. No? A minimum viable product is used not to validate if something is a good idea but that you can make it work; that you can acquire users through the means you think viable, you can monetize the business, and that you can learn from the users' experience and optimize that experience by improving the MVP. Now, that doesn't mean you just go build your MVP. I get the point of your question, but we should distinguish where you're at in the business and if you're ready for an MVP or you need to have more conversations with potential users. Worth noting, MOST entrepreneurs are ready to go right to an MVP. It's a bit of a misleading convention to think that entrepreneurs don't have a clue about the industry in which they work and what customers want; that is to say, you shouldn't be an entrepreneur trying to create this professional collaboration network if you don't know the market, have done some homework, talked to peers and friends, have some experience, etc. and already know that people DO want such a thing. Presuming you've done that, what would you present to potential users BEFORE actually building the MVP? For what do you need nothing more than some slides? It's not a trick question, you should show potential users slides and validate that what you intend to build is the best it can be. I call it "coffee shop testing" - build a slide of the homepage and the main screen used by registered users; sit in a coffee shop, and buy coffee for anyone who will give you 15 minutes. Show them the two slides and listen; don't explain, ONLY ask.... - For what is this a website? - Would you sign up for it? Why? - Would you tell your friends? Why? - What would you pay for it? Don't explain ANYTHING. If you have to explain something, verbally, you aren't ready to build your MVP - potential customers don't get it. Keep working with that slide alone until you get enough people who say they will sign up and know, roughly, what people will pay. THEN build your MVP and introduce it first to friends, family, peers, etc. to get your earliest adopters. At some point you're going to explore investors. There is no "ready" as the reaction from investors will entirely depend on who you're talking to, why, how much you need, etc. If you want to talk to investors with only the slides as you need capital to build the MVP, your investors are going to be banks, grants, crowdfunding, incubators, and MAYBE angels (banks are investors?! of course they are, don't think that startups only get money from people with cash to give you for equity). Know that it's VERY hard to raise money at this stage; why would I invest in your idea when all you've done is validate that people probably want it - you haven't built anything. A bank will give you a loan to do that, not many investors will take the risk. Still, know not that your MVP is "ready" but that at THAT stage, you have certain sources of capital with which you could have a conversation. When you build the MVP, those choices change. Now that you have something, don't talk to a bank, but a grant might still be viable. Certainly: angels, crowdfunding, accelerators, and maybe even VCs become interested. The extent to which they are depends on the traction you have relative to THEIR expectations - VCs are likely to want some significant adoption or revenue whereas Angels should be excited for your early adoption and validation and interested in helping you scale.

Likely you won't like my thoughts about this. When I give talks about business bootstrapping, I suggest people only work ideas which meet my "Sunset Rule". Sunset Rule - You should be able to go from idea to first sale, before sunset, or best consider other ideas. This also relates to your MVP. If you can't dream up an MVP + sell it before the sun goes down, best consider other ideas. Years ago, I was at an Internet Marketing Party mixer in Austin, TX + sat to visit with a friend. She was down because she was starting a new business + had spent months working on a business plan + determined she required $80K to bootstrap her business + then had spent another several months looking for investors. A buddy of mine + I sat with her for 15mins + slightly retooled her idea. She launched the next day for a one time investment of $144/year (cost of a Meetup.com account) + was generating some significant profit in a few days. Chunk down your MVP, so you can manually make sales by the end of the day... for $0 investment + you'll know for sure you have a profitable business. If you can't sell one unit, by the end of the day... best consider some other idea...
