How much & what type of programming language should a non technical CEO learn?

As you may suspect, there really isn't a hard and fast answer. You can review averages to see that a CEO typically becomes a major shareholder in a startup, but your role and renumeration will be based on the perceived value you bring to the organization. You value someone's contribution through equity when you think that they will be able to add long-term benefits, you would prefer that they don't move company part way through the process, and to keep them from being enticed by a better salary (a reason for equity tied to a vesting arrangement). Another reason is when the company doesn't have salary money available but the potential is very strong. In this situation you should be especially diligent in your analysis because you will realize that even the best laid plans sometimes fall completely short. So to get the best mix, you have to be very real about the company's long-term growth potential, your role in achieving it, and the current liquidity necessary to run the operations. It should also be realized that equity needs to be distributed. You cannot distribute 110% and having your cap table recalculated such that your 5% turns into 1% in order to make room for the newly hired head of technology is rather demotivating for the team. Equity should be used to entice a valuable person to join, stay, and contribute. It should not be used in leu of salary that allows an employee to pay their bills. So, like a lot of questions, the answer is really, it depends. Analyzing the true picture of your long-term potential will allow you to more easily determine the correct mix.

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.

Convertible notes are by no means "earned." They are often easier to raise for early-stage companies who don't want to or can't raise an equity round. Equity rounds almost always require a simultaneous close of either the whole round or a defined "first close" representing a significant share of the raised amount. Where there are many participants in the round comprised mostly of small seed funds and/or angel investors, shepherding everyone to a closing date can be very difficult. If a company raises money on a note and the company fails, the investors are creditors, getting money back prior to any shareholder and any creditor that doesn't have security or statutory preference. In almost every case, convertible note holders in these situations would be lucky to get pennies back on the dollar. It would be highly unusual of / unheard of for a convertible note to come with personal guarantees. Happy to talk to you about the particulars of your situation and explain more to you based on what you're wanting 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.

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.
