What should I look at before investing in a start-up?
Here are the basic questions I usually ask any new business startup: Do these numbers/answers seem reasonable to you and is some benchmark available that allows you to see how likely this is?   Remember, particularly in Internet-based advertising ventures, the client may be indirect.  The person who clicks on a Google context-based link is not directly Google's client.  The person who decided to host AdWords code on their site is the direct client. You're also going to want to see a Gant chart or some process chart indicating exactly what needs to be done, at what cost and by whom.  Answers to these questions give a sense of not only how seriously they are taking the business, but also how organised. My final question: who is your first client? They need either someone who is going to contract the service, or have a clear indication of where income is going to come from, on their first day of trading. Their task is to sell their idea to you by proving that it will return on your investment and be profitable.  From the strength of these answers you can gauge the value of your investment to them, how critical it is, how risky the opportunity and - ultimately - the stake and returns you should expect. In addition to evaluating the business (great answer), consider the potential payoff. If bonds pay off in the 5-10% range, the S&P500 has averged 10.5%. You should be expecting a payoff of 15-20% to invest in something riskier than the stock market.  That means that if you invest $10k, then in 5 years you'll need to get out $25K (20% returns over 5 years).   If you get less than this much in 5 years, the risk-to-reward ratio probably rules this out as a good investment. Turukawa's answer is quite good, and for your own specific situation, you might begin by being sceptical about what you are getting for investing a few thousand dollars.  With the exception of Paul Graham's Y-Combinator, there are very few opportunities to invest at that type of level, and Y-Combinator provides a lot of other assistance besides their modest initial investment.   I can tell from your post that you think like an investor.  It is highly unlikely that the entrepreneurial programmers that you will be backing will be wired that way.   From the modest amount that you are investing, you are unlikely to be the lead investor in this opportunity.  If you are interested in proceeding, simply stick along for the ride, examining the terms and documents that more significant investors will be demanding.  Remain positive and supportive, but simply wait to sign on the dotted line until others have done the heavy lifting.

Good luck. "Previous answers have done a great job with the ""Should I invest?"" question.   One thing you may be overlooking is the question ""Am I allowed to invest?"" For most offerings of stock in a startup, investors are required to be accredited by the SEC's definition.  See this helpful quora post for more information on requirements to invest in startups. To be honest, if a startup is looking for investors to put in ""a few thousand dollars"" each, this would raise my alarm bells.  The cost and hassle of the paperwork to (legitimately) issue shares in that small of number would lead me just to use a credit card to keep me going until I was able to raise a larger amount of capital." "You seem to have all your financial bases covered, and others have given you good financial advice, so I will try to give you some non-financial ideas. The first and most important thing is that you are investing with a long time friend, so the dynamics are a lot different that if you had recently met a stranger with an ""interesting"" new idea. The first thing you need to ask yourself is if your friendship will survive if this thing doesn't go well? You've already said you can afford to lose the money so that's not a worry, but will there be any ""recriminations?"" The flip side is also true; if the venture succeeds, you should be able to go further with it because he's your friend. You know your friend better (back to grade school) than almost anyone else, so here are some things to ask yourself: What does your friend have that will give him a chance to succeed; tech savvy, a winning personality, a huge rolodex, general business savvy, something else? If your guardian angel had told you that one of your friends was planning to embark on an internet/advertising venture, is this the one you would have guessed? Conversely, knowing that your friend was planning to do a start up, is this the kind of venture you would have guessed? How does ""internet"" and ""advertising"" fit in with what you are doing? If this venture succeeds, could it be used to help your professional development and career, maybe as a supplier or customer? Can you see yourself leaving your current job and joining your friend's (now established) company as a vice president or acting as a member of its board of directors, the latter perhaps while pursuing your current career path?  Are your other mutual friends investing? Are some of them more tech savvy than you and better able to judge the company's prospects of success? To a certain extent, there is ""safety in numbers"" and even if there isn't, ""misery loves company."" On the upside, would you feel left out if everyone in your crowd caught ""the next Microsoft"" except you?"
"It all depends on what your financial goals are when you are ready.  You sound like you could be ready today if you wanted to be.  The steps that I would take are. Create a monthly draft budget.  This doesn't have to be something hard and fast, just a gague of what your living expenses would be compared to your after-tax salary.  Make sure there  would be room for ""fun"" money. a. Consider adding a new car fund line item to this budget, and deducting that amount from your paycheck starting now so that you can save for the car. Based on the most realistic estimate that you can make, you'll get a good idea if you want to spend the money it takes to move out alone now or later.  You'll also see the price for various levels of rentals in your area (renting a single family home, townhouse, condo, apartment, living in a rented room or basement, sharing a place with friends, etc) and know some of the costs of setting up for yourself.  Since you're looking at the real estate market, you may want to do a cost comparison of renting versus buying.  I've found the New York Times interactive graphic on this is excellent.  If you are looking to buy, make sure to research the hidden costs of buying thoroughly before taking this step. To answer your last question, if you have the cash you should consider upping your 401K investment (or using Roth or regular IRA).  Make sure you are investing enough to get your full employer match, if your employer offers one, and then get as close as you can to government maximum contribution limits.  Compound interest is a big deal when you are 23." My super fund and I would say many other funds give you one free switch of strategies per year.  Some suggest you should change from high growth option to a more balance option once you are say about 10 to 15 years from retirement, and then change to a more capital guaranteed option a few years from retirement. This is a more passive approach and has benefits as well as disadvantages. The benefit is that there is not much work involved, you just change your investment option based on your life stage, 2 to 3 times during your lifetime. This allows you to take more risk when you are young to aim for higher returns, take a balanced approach with moderate risk and returns during the middle part of your working life, and take less risk with lower returns (above inflation) during the latter part of your working life. A possible disadvantage of this strategy is you may be in the higher risk/ higher growth option during a market correction and then change to a more balanced option just when the market starts to pick up again. So your funds will be hit with large losses whilst the market is in retreat and just when things look to be getting better you change to a more balanced portfolio and miss out on the big gains. A second more active approach would be to track the market and change investment option as the market changes. One approach which shouldn't take much time is to track the index such as the ASX200 (if you investment option is mainly invested in the Australian stock market) with a 200 day Simple Moving Average (SMA). The concept is that if the index crosses above the 200 day SMA the market is bullish and if it crosses below it is bearish. See the chart below:  This strategy will work well when the market is trending up or down but not very well when the market is going sideways, as you will be changing from aggressive to balanced and back too often. Possibly a more appropriate option would be a combination of the two. Use the first passive approach to change investment option from aggressive to balanced to capital guaranteed with your life stages, however use the second active approach to time the change. For example, if you were say in your late 40s now and were looking to change from aggressive to balanced in the near future, you could wait until the ASX200 crosses below the 200 day SMA before making the change. This way you could capture the majority of the uptrend (which could go on for years) before changing from the high growth/aggressive option to the balanced option. If you where after more control over your superannuation assets another option open to you is to start a SMSF, however I would recommend having at least $300K to $400K in assets before starting a SMSF, or else the annual costs would be too high as a percentage of your total super assets. "You don't seem to be a big fan of trading as you may think it may be too risky or too time consuming being in front of your computer all day long. You also don't seem to be a fan of buy and hold as you don't know what your investments will be worth when you need the funds. How about a combination of the two, sometimes called trend trading or active investing. With this type of trading/investing you may hold a stock from a couple of months to many years. Once you buy a stock that is up-trending or starting to up-trend you hold onto it until it stops up-trending. You can use a combination of fundamental analysis (to find out what to buy) and technical analysis (to tell you when to buy and when to sell). So these are some topics you can start reading up on. Using a technique like this will enable you to invest in healthy stocks when they are moving up in price and get out of them when they start moving down in price. There are many techniques you can use to get out of a stock, but the simplest has to be using stop losses. And once you learn and set up your system it should not take up much of your time when you actually do start trading/investing - 2 to 3 hours per week, and you can set yourself up that you analyse the market after the close and place any order so they get executed the next trading day without you being in front or the screen all day. Other areas you might want to read and learn about are writing up a Trading Plan, using Position Sizing and Money Management so you don't overtrade in any one single trade, and Risk Management. A good book I quite liked is ""Trade Your Way to Financial Freedom"" by Van Tharp. Good luck." "The response to this question will be different depending which of the investment philosophies you are using.  Value investors look at the situation the company is in and try to determine what the company is worth and what it will be worth in the future. Then they look at the current stock price and decide whether or not the stock is priced at a good deal or not. If the stock price is priced lower than they believe the company is worth, they would want to buy stock, and if the price rises above what they believe to be the true value, they would sell. These types of investors are not looking at the history or trend of what the price has done in the past, only what the current price is and where they believe the price should be in the future.  Technical analysis investors do something different. It is their belief that as stock prices go up and down, they generally follow patterns. By looking at a chart of what a stock price has been in the past, they try to predict where it is headed, and buy or sell based on that prediction.  In general, value investors are longer-term investors, and technical analysis investors are short-term investors.  The advice you are considering makes a lot of sense if you are using technical analysis. If you have a stock that is trending down, your strategy probably tells you to sell; buying more in the hopes of turning things around would be seen as a mistake. It is like the gambler in Vegas who keeps playing a game he is losing, hoping that his luck changes.  However, for the value investor, the historical price of a stock, and even the amount you currently have gained or lost in the stock, are essentially ignored. All that matters is whether or not the stock price is above or below the true value determined by the investor. For him, if the stock price falls and he believes the company still has a high value, it could be a signal to buy more. The above advice doesn't really apply for them.  Many investors don't follow either of these strategies. They believe that it is too difficult and risky to try to predict the future price of an individual stock. Instead, they invest in many companies all at once using index mutual funds, believing that the stock market as a whole always heads up over a long time frame. Those investors don't care at all if the prices of stock are going up or down. They simply keep investing each month, and hold until they have another use for the money. The above advice isn't useful for them at all.  No matter which kind of investing you are doing, the most important thing is to pick a strategy you believe in and follow the plan without emotion. Emotions can cause investors to make mistakes and start buying when their strategy tells them to sell.  Instead of trying to follow fortune cookie advice like ""Don't throw good money after bad,"" choose an investment strategy, make a plan, test it, and follow it, cautiously (after all, it may be a bad plan). For what it is worth, I am the third type of investor listed above. I don't buy individual stocks, and I don't look at the stock prices when investing more each month. Your description of your own strategy as ""buy and hold"" suggests you might prefer the same approach." "If your business is structured as a partnership or sole proprietorship you call this investment ""partner equity"".  If instead it is structured as a corporation, then the initial investment is called ""paid-in capital"".  Either way, this represents the capital the initial investors or partners provided to the company in exchange for their ownership stake. The most important thing in your case is that since that initial investment is in the form of inventory, you are going to have to document the value of that investment somehow.  You will definitely need a comprehensive manifest of what you contributed, including titles and condition, and if possible you should document the prices at which similar items are being offered for sale at the time you start operating.  Having this information will support your claims as to the fair market value of the start-up contribution, should the tax authorities decide to question it." Don't start by investing in a few individual companies. This is risky. Want an example? I'm thinking of a big company, say $120 billion or so, a household name, and good consistent dividends to boot. They were doing fairly well, and were generally busy trying to convince people that they were looking to the future with new environmentally friendly technologies. Then... they went and spilled a bunch of oil into the Gulf of Mexico. Yes, it wasn't a pretty picture if BP was one of five companies in your portfolio that day. Things would look a lot better if they were one of 500 or 5000 companies, though. So. First, aim for diversification via mutual funds or ETFs. (I personally think you should probably start with the mutual funds: you avoid trading fees, for one thing. It's also easier to fit medium-sized dollar amounts into funds than into ETFs, even if you do get fee-free ETF trading. ETFs can get you better expense ratios, but the less money you have invested the less important that is.) Once you have a decent-sized portfolio - tens of thousands of dollars or so - then you can begin to consider holding stocks of individual companies. Take note of fees, including trading fees / commissions. If you buy $2000 worth of stock and pay a $20 commission you're already down 1%. If you're holding a mutual fund or ETF, look at the expense ratio. The annualized real return on the stock market is about 4%. (A real return is after adjusting for inflation.) If your fee is 1%, that's about a quarter of your earnings, which is huge. And while it's easy for a mutual fund to outperform the market by 1% from time to time, it's really really hard to do it consistently. Once you're looking at individual companies, you should do a lot of obnoxious boring stupid research and don't just buy the stock on the strength of its brand name. You'll be interested in a couple of metrics. The main one is probably the P/E ratio (price/earnings). If you take the inverse of this, you'll get the rate at which your investment is making you money (e.g. a P/E of 20 is 5%, a P/E of 10 is 10%). All else being equal, a lower P/E is a good thing: it means that you're buying the company's income really cheap. However, all else is seldom equal: if a stock is going for really cheap, it's usually because investors don't think that it's got much of a future. Earnings are not always consistent. There are a lot of other measures, like beta (correlation to the market overall: riskier volatile stocks have higher numbers), gross margins, price to unleveraged free cash flow, and stuff like that. Again, do the boring research, otherwise you're just playing games with your money. I think this piece would be great with some direction and editing.  The idea of JOINING a start up can be considered a long con. You are not working for yourself nor a cause you created or developed. The pay is very low, the hours are long and the promise of equity might either never be there (Remember Zynga taking back equity?), be poorly constructed (Pay-in options are just like equity right? Right guys?) or worse, might be worthless through no fault of your own.  Where will you be if either happens? The idea that you stuck around with a company for 3-6 years in order to maximize your equity value is not only limiting, it can be career damaging. 20 year olds should be trying different careers and gaining a sea of experience. Go out and build up that all important network isn't going to happen in one place. "I have personally invested $5,000 in a YieldStreet offering (a loan being used by a company looking to expand a ridesharing fleet), and would certainly recommend taking a closer look if they fit your investment goals and risk profile. (Here's a more detailed review I wrote on my website.) YieldStreet is among a growing crop of companies launched as a result of legislative and regulatory changes that began with the JOBS Act in 2012 (that's a summary from my website that I wrote after my own efforts to parse the new rules) but didn't fully go into effect until last year. Most of them are in Real Estate or Angel/Venture, so YieldStreet is clearly looking to carve out a niche by assembling a rather diverse collection of offerings (including Real Estate, but also other many other categories). Unlike angel/venture platforms (and more like the Real Estate platforms), YieldStreet only offers secured (asset-backed) investments, so in theory there's less risk of loss of principal (though in practice, these platforms haven't been through a serious stress test). So far I've stuck with relatively short-term investments on the debt crowdfunding platforms (including YieldStreet), and at least for the one I chose, it includes monthly payments of both principal and interest, so you're ""taking money off the table"" right away (though presumably then are faced with how to redeploy, which is another matter altogether!) My advice is to start small while you acclimate to the various platforms and investment options. I know I was overwhelmed when I first decided to try one out, and the way I got over that was to decide on the maximum I was willing to lose entirely, and then focus on finding the first opportunity that looked reasonable and would maximize what I could learn (in my case it was a $1,000 in a fix-and-flip loan deal via PeerStreet)."
