Once an MVP is on, how long does it take to be sure my start up is successful and go to the next stage? Which number do I need to know it was success?

Better than a cover letter is to actually proactively DO something to help them. It'll show them not only that you've researched them, but you're passionate about the startup and worth bringing on. A man got a job at Square early on for just making them a marketing video on his own (back before they had one). Since you're a web designer, design a stellar 1-pager that's targeting their message to a particular niche. Something they could use on social media or something. If they're like most startups, they're not interested in reading cover letters. They're interested in passionate individuals who can add value to the organization.

I have built several multi-million dollar businesses using (2) very simple questions: "What makes you say that...." and "Tell me more...." No matter what someone says to you, you just keep asking one (or both) of the questions. If you do it 4 or 5 times in a row you'll learn everything you ever wanted to know.

I've discussed ideas with hundreds of startups, I've been involved in about a dozen startups, my business is at $1M+ revenue. The bad news is, there is no good way to protect ideas. The good news is, in the vast majority of cases you don't really need to. If you're talking to people about your idea, you could ask them to sign an NDA ("Non Disclosure Agreement"), but NDAs are notoriously hard to enforce, and a lot of experienced startup people wouldn't sign them. For example, if you asked me to sign an NDA before we discussed your Idea, I'd tell you "thanks, but no thanks". This is probably the right place though to give the FriendDA an honorable mention: http://friendda.org/. Generally, I'd like to encourage you to share your Ideas freely. Even though telling people an idea is not completely without risk, generally the rewards from open discussions greatly outweigh the risks. Most startups fail because they build something nobody wants. Talking to people early, especially people who are the intended users/customers for your idea can be a great way to protect yourself from that risk, which is considerably higher than the risk of someone taking off with your idea. Another general note, is that while ideas matter, I would generally advise you to get into startup for which you can generate a lot of value beyond the idea. One indicator for a good match between a founder and a startup is the answer to the question: "why is that founder uniquely positioned to execute the idea well". The best way to protect yourself from competition is to build a product that other people would have a hard time building, even if they had 'the idea'. These are usually startups which contain lots of hard challenges on the way from the idea to the business, and if you can convincingly explain why you can probably solve those challenges while others would have a hard time, you're on the right path. If you have any further questions, I'd be happy to set up a call. Good luck.

The ways I've done this in the past are 1) Find some customers that are willing to hire you (or your product) but know that you'll only be free nights & weekends to support/work with them. 2) Find a "partner" (co-founder or other) that's got a flexible schedule that can help build the business while you're at work. 3) Block out nights, mornings and weekends to build the business till you have enough orders to cover 50% of your salary. This might mean 7pm-11pm most nights, and 4 hours each day Sat & Sun. Make progress (sales $$$) and momentum. All that being said, it's risk reward. Sounds like you want to avoid taken the risk, and I get that .. but the upside is always smaller. Unless you put yourself in a position to have to succeed (ex: quitting your job) then you may never make the scary decisions that are required to build a company (like cold calling, going in debt, making a presentation, etc). I'm on company #5 with many other side projects started nights & weekends .. so I get it - but don't be afraid to bet on yourself and go all in.

You will find a lot of different views on equity split. I haven't found a silver bullet. My preference/experience is for: 1. Unequal shares because one person needs to be the ultimate decision maker (even if it's 1% difference). I have found that I have never had to use that card because we are always rational about this (and I think us being rational is driven because we don't want a person to always pull that card cause it's a shitty card to pull) 2. When it comes to how much equity, I like Paul Graham's approach best: if I started the business by myself, I would own 100% of the equity; if xxx joined me, he/she would increase my chances of success by 40% (40% is just an example) at this moment in time. Therefore, I should give him/her 40% of the company (http://paulgraham.com/equity.html) 3. In terms of range, it could go between (15-49%) depending on the level of skill. But anything less than 15%, I would personally not feel like a cofounder 4. Regarding salary and the fact that you will pay him/her, that's tricky but a simple way to think about it: If an outside investor were to invest the equivalent of a salary at this exact moment into the startup, what % of the company would they get? (this may lowball it if you think the valuation is high but then again if you think you could get a high valuation for a company with no MVP, then you should go raise money) One extra thing for you to noodle on: given you are not technical, I would make sure a friend you trust (and who's technical) help you evaluate the skill of your (potential) cofounder. It will help stay calibrated given you really like this person.
