There’s been a pile of negative news about cleantech start-ups recently. I’ve heard it said more than once in the past month that venture-backed entrepreneurship clearly isn’t working here, so maybe we should all pack our bags and go home. Given the human bias to extrapolate individual events into overarching trends, I figured now would be a good time to review the data so far about cleantech VC performance – and I stress data, not anecdote or assertion! – to see what we can learn.
This is a meaty topic, so I’m going to cover it in four posts. Today I’m going to focus on the money – how much capital has been available for cleantech start-ups so far, and what we can expect in the next few years. Two subsequent posts will address the VC investors that are supplying this cash, as well as the experiences of start-up companies that have achieved liftoff. In the final post, I’ll wrap it all up with some parting thoughts.
The chart below shows cleantech start-up investment from 1995 through 2010. My data set is cobbled together from multiple sources, aiming to capture the breadth of the energy, environmental, materials, and agricultural technologies that most people refer to when they say “cleantech.” Varying definitions mean that these figures won’t equal those from the Moneytree survey or the Cleantech Group, but the trends should be the same. I divide this era into four periods. During each, cleantech start-up investment had a different driver:
- 1995 to 1999: Baseline. This period shows us what cleantech start-up financing looks like when there’s no external forcing function to influence it. The answer is $200 million +/- $100 million per year in 30-50 transactions annually. During this period the venture capital industry as a whole grew dramatically – from about $7 billion invested per year to more than $50 billion – so cleantech accounted for a shrinking percentage of the total.
- 2000 to 2005: Bubble fumbling. The year 2000 saw the peak of the Internet bubble and a commensurate peak in total venture capital investment: An all-time record of nearly $100 billion went into start-up companies that year, mostly of the Internet variety. But the bubble promptly burst, and VC firms that had just raised billions of fresh dollars had to find something other than dot-com start-ups to invest them in.
I’d characterize what happened in the years that followed as “fumbling around for another bubble,” marked by broad interest in the physical sciences instead of cleantech per se (you may recall this as the time when nanotechnology became an investment meme). Cleantech benefited considerably from the fumbling, however, and in 2005 start-up investment in the field broke $800 million – several times greater than in the late ‘90s.
- 2006 to 2008: Gold rush. Starting in 2006, cleantech became a major VC focus area, and start-up financing rose by 50 percent + annually for three years. You might think this happened because all the venture capitalists went to see “An Inconvenient Truth” on the same night, but I think a different sort of herd mentality was at work: In Q4 2005, three solar companies went public, all at valuations around $1 billion – namely Q-Cells, SunPower, and Suntech – and hundreds of VC firms hopped on the bandwagon. (You may mock the VC asset class for collectively deciding that cleantech was the next big thing, but you may also respect it for recognizing the intersection of favorable secular trends with a quarter-century of neglected tech innovation!)
As a result, cleantech start-up financing skyrocketed to exceed $4.5 billion in 2008. Note that toward the end of this period, after initial bets were placed, money began to shift away from brand-new companies: Seed/Series A financing fell by 29 percent from 2007 to 2008.
- 2009 to now: Retrenchment. In September 2008, Lehman Brothers filed for bankruptcy and the stock market went into free-fall, losing 30 percent of its value by year-end. This spooked investors of all types, venture capitalists included, and cleantech start-up investment dropped by a third in 2009. For entrepreneurs launching new businesses, the more significant development was that Seed/Series A funding fell by half, returning to 2006 levels.
2010 brought a substantial recovery, but not a new peak, while Seed/Series A funding for new start-ups stagnated. As for 2011, the year’s not over yet, but based on current figures this year will be flat or down overall with a level of Seed/Series A investment comparable to 2010.
Now let’s zoom in and look at just the last five years. Three big trends come into focus:
- Financing rose sharply to a peak in 2008 and bounced around after that.
- Late-stage financing has ballooned as more companies have “graduated” to big Series D and later rounds, where they need lots of cash to build factories, hire sales forces, establish distribution channels, etc.
- Seed/Series A financing for brand-new businesses has fallen substantially.
So far we’ve been looking at this data by dollars invested. We can also look at it by rounds completed:
This evens out the visual a bit because the late-stage investments aren’t weighted up by their disproportionate value. However, they still predominate: Sixty-six Series D and later rounds were raised last year, more than other stage. In contrast, the number of early-stage investment rounds has plummeted. Nearly 100 new cleantech companies per year received seed/Series A funding in 2007 and 2008, but only 50 or so did in 2009 and 2010.
All of this rear-facing stuff is fine and good, but if I’m an entrepreneur, I want to know what’s going to happen in the future. If my cleantech business will require lots of late-stage capital down the road, what is the competition for that money going to look like?
We can answer this question by using yesterday’s financing data to project tomorrow’s capital requirements. We know, historically, the percentage of companies that have “graduated” from Seed/Series A to Series B, B to C, and so on. We also know the proportionate amounts of money that companies tend to raise in each round, and we can make an informed guess at how long each round of funding lasts.
Equipped with these numbers, we can build a simple forecast of how much cleantech start-up financing will be required in the future. I used the assumptions below. (One big thing to note: For simplicity’s sake, I’ve assumed that the number of new companies raising Seed/Series A financing each year – as well as the average Seed/Series A round size – will remain at 2009-2011 levels. This obviously won’t happen, but it’s not important to the argument I’m going to make.)
When we apply these assumptions about the future to the population of companies launched in the past, we generate this forecast:
You can see the big takeaway here: There will be a path-breaking requirement for late-stage financing in 2012-2014 as the “baby boom” of companies formed in the last five years plays out. In 2008-2010, an average of $1.8 billion per year went into Series D and later rounds – but during 2012-2014, an average of $3.3 billion per year will be needed. That’s an extra $1.5 billion in late-stage financing annually, or $4.5 billion across the three years.
So will this money be available? Or will otherwise-auspicious cleantech start-ups go begging?
I’m betting that the money will be there. I posit that a number of VC and private equity pros all ran this spreadsheet a year ago, reached the same conclusion, and started raising late-stage funds. Examples include:
- VantagePoint is reportedly in the market for a $1.25 billion cleantech growth fund.
- Silver Lake Kraftwerk, a new vehicle also raising money now, is said to have a $1 billion target.
- BlackRock and NTR announced a new late-stage cleantech fund back in February. I’m not sure where this one stands, but if it goes forward, a fund smaller than $1 billion would be out of character.
- Kleiner’s $500 million Green Growth Fund – first allocated in 2008 – has apparently been re-upped, since it’s now self-described as a “$1 billion initiative”.
- Khosla’s new $1 billion fund is half-allocated to cleantech, and I’d bet most of that portion is aimed at late-stage investment – perhaps $300 million?
- Hudson Clean Energy’s $1 billion first fund, raised in 2009 and focused exclusively on late-stage investments, should still have some fresh capital – and in the meantime the firm appears to be raising a second one worth $1.5 billion
The entities above would get you near $4.5 billion all by themselves, and the shift to later-stage allocations among all the other VC investors should be sufficient to cover any shortfall. So I think we can conclude that there will indeed be adequate late-stage financing for cleantech start-ups in the next few years – and happily so, since the need will be unprecedented.
My concern, as you might expect, is that there may be insufficient Seed/Series A capital available to fund new cleantech enterprises. The limited partners who supply VC firms with money to invest are putting less and less capital into VC overall, and the share of that money that will be allocated to cleantech is unlikely to grow in the near term. If shrinking cleantech allocations get disproportionately earmarked toward late-stage investment, Seed/Series A capital will be thin on the ground. I’m self-interested in this because our team at Venrock invests early, we prefer to do so in conjunction with peers, and we already have fewer co-investors available to us now than we did two years ago.
This brings us to a different question: What would have to happen for LPs to pump more money into cleantech rather than the same or less? That depends on returns, which I’ll address in the next post.
