New Trends In Startup Financing Explained For Laymen

Noted American technology investor and all-around smart guy Paul Graham wrote recently about emerging trends in startup funding, specifically that convertible notes and rolling closes are displacing the traditional equity rounds done at a fixed valuation done with angel syndicates.

Did that sound like Greek to you?

Great, you might benefit from this translation of Financier into Geek.  (P.S. If you haven’t figured out the significance of it originally being written in Financier instead of in Geek, please, think it through.)  I originally wrote it as a comment on Hacker News but somebody asked me to put it somewhere easily findable.  I have elaborated with standard blog post formating and graphs where I thought they helped the explanation:

Why We Care About Angel Investing

Startups raise money from investors to accelerate their growth into, hopefully, massively profitable businesses and/or massively large acquisitions from big companies.

One particular type of investor that invests in startups is called an angel investor. An angel investor is often an individual human being who is wealthy, frequently as a consequence of successful entrepreneurship. They invest anywhere from $25,000 to $250,000 or so.

Fundraising is painful, and requires a lot of time and focus from startup founders. To mitigate the pain, it is often structured in terms of “rounds”, where the startup goes out to raise a particular large sum of money all at once. For an angel round, let’s say that could be a million dollars. (n.b. It is trending down, as companies can now be founded for sums of money which would have been laughable a few years ago.)  Clearly we’re going to need to piece together contributions from a few angels here.

Why Angel Investing Frustrates Founders

Traditionally, one angel has been the “lead” angel, who handles the bulk of the organizational issues for the investors. The rest just sit by their phone and write checks when required. (Slight exaggeration.) Investors are often skittish, and they require social proof to invest in companies, so you often hear them say something like a) they’re not willing to invest in you but b) they are willing to invest in you if everybody else does. This leads to deadlocks as a group of investors, who all would invest in the company if they company were able to raise investment, fail to invest in the company because it cannot raise investment.

Startup founders are, understandably, frustrated by this.

What “Valuation” Means

All numbers below this point were chosen for ease of illustration only.  They do not represent typical valuations, round sizes, or percentages of companies purchased by angels.

One item of particular interest in investing is the valuation of the company. This gets into heady math, but the core idea is simple: if we agree that the company is worth $100 at this instant in time (the “pre-money valuation”), and you want to invest $100, then right after the company receives your investment, the company is worth $200 (the “post-money valuation”). Since you paid $100, you should own half the company.

Traditionally, the company has exactly one pre-money valuation (which is decided solely by negotiation, and bears little if any relation to what disinterested outside observers could perceive about the company). All investors receive slices in the company awarded in direct proportion to the amount of money they invest. Two investors investing the same amount of money receive the same sized slice of the company. This can be written as “they invested at the same valuation.”

The thesis of PG’s essay is that allowing investors to invest at the same valuation is not advantageous to the startup. Instead, by offering a discount to valuation for moving quickly, you can convince investors to commit to the deal early, thus starting the stampede from the hesitant investors who were waiting to see social proof.

For example, take the company from earlier. We said it was worth $100 prior to receiving investing, but that is not tied to objective reality. Say instead we’ll agree that it is worth $80… but only with respect to the 1st investor. He commits $20. $80 + $20 = $100, so he gets $20 / $100 = 20% of the company for $20, or $1 = 1%. This convinces a second investor to invest. He says “Can I get 20% for $20, too?” Not so fast, buddy, where were you yesterday? The company isn’t worth $80 any more. We think it is worth $105 now. (Did we just get through saying $100? Yes. But valuations are not connected to objective reality.) So you get $20 / ($105 + $20) = 16% of the company for your $20. Think that is fair? You do? OK, done.

This continues a few times. The startup raises money — possibly more money, depending on how much the angels want in — with less hassle for the founders.

What Is A Convertible Note?  Why Do Founders Like Them?

We’ve been talking about just dollars so far, and alluding to control of the company as if it were equity like stocks, but there is a mechanism called “convertible notes” at play here. A convertible note is the result of a torrid affair between a loan and an equity instrument. It looks a bit like Mom and a bit like Dad. Like a loan, it charges interest: typically something fairly modest like 6 to 8%, much less than a credit card.

The tricky thing about convertible notes is that they convert into partial ownership of the company at a defined event, most typically at the next round of VC funding or at the sale of the company. So, instead of the first investor getting $20 = 20% of the company, he loans the company $20 in exchange for a promise like this: “You owe me $20, with interest. Don’t worry about paying me back right now. Instead, next time you raise money or sell the company, we’re going to pretend that I’m either investing with the other guy or selling with you. The portion of the company which I buy or sell will be based on complicated magic to protect both your interests and my interests. If you want to sweeten the deal for me, sweeten the magic.”

Do we understand why this arrangement works for both parties? It incentivizes investors to commit early, which lets startups raise more money with less pain. Because startups are in the driver’s seat, it also lets them avoid collusion among investors (“We decided we’d all invest in you, but we don’t think the company is worth $100. We think it is worth $50. Yeah, that has no basis in objective reality, but objective reality is that your company is worth $0 without the $100 in our collective pockets. What is it going to be? Give up 2/3 of the company, or go broke and get nothing.”)

How Do You Calculate The Equity Value of A Convertible Note?

OK, back to complicated magic. When the company takes outside investment, the convertible notes magically convert into stock, based on:

  • a) the valuation the company receives for the investment round  (higher numbers are better for both founders and angels)
  • b) a negotiated discount to the valuation, to reward the angel investor for his early faith in the company (higher numbers are better for angels)
  • c) possibly, a valuation cap (higher numbers, or no cap,  are better for founders)

For example, continuing with our “low numbers make math comprehensible” startup, let’s say it goes on a few months and is then raising a series A round, which basically means “the first time we got money from VCs”. We’ll say the VC and startup negotiate and agree that the company is worth $500 today, the VC is investing $250, ergo the VC gets a third of the company.

How much does our first $20 angel investor get? Well, he gets to participate like he was investing $20 today, plus he gets a discount to the valuation. So instead of getting $20 / $750 = 2.67% of the company, maybe he got a 20% discount to the valuation, so he gets $20 / (.8 * $750) = 3.33% of the company. (We’re ignoring the effect of interest here for simplicity, but he probably effectively has $21 and change invested by now in real life.)

After this is over, the convertible note is gone, and our angel investors are left with just shares (partial ownership of the company), which they probably hold until the company either goes IPO or gets bought by someone. So if the company later gets bought for $2,000 by Google, our intrepid angel investor makes $66 on his $20 investment.

How Does A Valuation Cap Work?

We haven’t discussed valuation caps yet. Valuation caps are intended to prevent the startup dragging its feet on raising money, thus building up lots of worth in the company, and then the angel investor getting cheesed. For example, if they had just grown through revenues for a year or two, they might be raising money at a valuation of $1,250. In that case, $20 only buys you 2% of the company (remember, he gets a 20% discount : $20 / (.8 * $1250) = 2%), which the angel investor might think doesn’t adequately compensate him for the risk he took on betting on a small, unproven thing several years before. So we make him a deal: he gets to invest his $20 at the same terms as the VCs do if, and only if, the valuation is less than $750. If it is more than $750, for him and only him, we pretend it was $750 instead. This means that under no circumstances will he walk away with less than $20 / (.8 * $750) = 3.33% of the company, as long as the company goes on to raise further investment. (Obviously, if they fold, he walks away with nothing. Well, technically speaking, with debt owed to him by a company which is bankrupt and likely has no assets to speak of, so essentially nothing.)

Perhaps This Will Be Clearer With A Picture

Angels ultimately benefit from higher discounts to the valuation of the Series A round, and lower valuation caps.  Higher discounts, and higher effective discounts, mean you get more of the company for less money.  That is an unambiguous good, as long as you keep the quality of the company constant.

Let’s see how valuation caps affect how much of the company you end up with.  The better the company is doing by Series A time, the less of the company the angel ends up with.  This shows the incentive for the founders: do as well as you can prior to raising money, which is the same incentive founders always have.

As you can see from the below graph, a valuation cap essentially gives the angel an artificially higher discount for if the Series A valuation exceeds the valuation cap.  Obviously then, it is in the interest of angels to negotiate as low a cap as possible, and in the interests of founders to negotiate a high cap or no cap at all. According to Paul Graham, this becomes the primary “pricing” mechanism in the new seed financing economy: if a founder wants to reward an angel, they award them with a lower cap.  If they don’t, the angels get a higher cap, or no cap at all.  This kicks discussions of valuations down the road a little bit, and allows you to simultaneously offer the company to multiple angels at multiple “price points”.  That allows you to reward them for non-monetary compensation (mentoring, having a big name, etc) or for early action on the deal.

This Is Not My Business. Take With A Grain Of Salt.

Lest anyone get the wrong impression, my familiarity with angel investing is very limited and, to the extent that it exists, it is mostly about angel investing in small town Japan.  (Oh, the stories I can’t tell.)  The above explanation is based on me processing what I’ve read and trying to prove that I understand it by explaining it to other people.  If I have made material errors, please correct me in the comments.

My current business is not seeking funding (and would be an extraordinarily poor candidate for it).  I’ll never say never for the future, but for the present, I rather like getting 100% of the returns.

    Nice explanation Patrick. I understand that you chose “nonsense” numbers to remove distraction, but I still think things would be clearer if you had chosen numbers that could make sense (such as a $250k angel round investment, $2-5MM Series A, $20MM exit, etc…).

    Great post. Really makes things simple. Thanks!

  5. dustin September 2, 2010 at 5:48 pm #

    To distill your explanations still further:

    post_money_valuation = pre_money_valuation + amount_invested

    share_of_company = post_money_valuation / amount_invested

    Thanks, this wasn’t clear to me before.

    Your article was very informative and palatable. Out of curiosity,what do you use to do your charts and graphs?

    Whenever possible, it’s much preferable to debt use debt finance, as opposed to equity finance. Although debt carries a very visible expense, equity finance costs you much more over the long run!

    Great post, very informative.
    Thanks.
