What strategies are there to form a company at an early stage that is flexible (equity, control/titles, and business model)?

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.

Before I get to your question, let me give you a tip: always aim settle questions of payment before the work happens. It is ten times easier to agree on a price beforehand, and having done that doesn't stop you from changing it by mutual agreement later. The problem with paying cash is pretty obvious: you don't have a lot of it. The problems with paying equity are subtler. The first one is that early-stage equity is extremely hard to value. A second is that equity transactions require a lot of paperwork. Third is that entrepreneurs tend to value their equity much higher than other people would; if not, they wouldn't be starting the company. And fourth, people like designers are rarely expert in valuing businesses or the customs of of startup equity valuation. In the past, I've both given and received equity compensation, and it's a lot more of a pain than I expected. In the future, what I think I'd try is convertible debt. That is, I'd talk with the designer and agree on a fair-market wage. E.g. 100 hours x $100/hr = $10k. The next time we take investment, the $10k turns into stock at whatever price we agree with our investors, plus a discount because he was in before the investors. Note, though, that this will increase your legal costs and your deal complexity, so I'd personally only do this for a pretty significant amount of work. And I'd only do it for somebody I trusted and respected enough to have them around for the life of my business.

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.

Cash money should be treated separately than sweat equity. There are practical reasons for this namely that sweat equity should always be granted in conjunction with a vesting agreement (standard in tech is 4 year but in other sectors, 3 is often the standard) but that cash money should not be subjected to vesting. Typically, if you're at the idea stage, the valuation of the actual cash going in (again for software) is anywhere between $300,000 and $1m (pre-money). If you're operating in any other type of industry, valuations would be much lower at the earliest stage. The best way to calculate sweat equity (in my experience) is to use this calculator as a guide: http://foundrs.com/. If you message me privately (via Clarity) with some more info on what the business is, I can tell you whether I would be helpful to you in a call.

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.
