To understand the future of cleantech, we must analyze the past.
By Matthew Nordan, contributor
I entered the venture capital business two years ago, focusing on cleantech start-ups. It’s kind of like picking a future NBA draft by watching eighth graders play basketball: There are many years worth of development to go, and the subjects will look a lot different once they’re all grown up. The key is excellent pattern recognition – identifying the antecedents of success long before it happens.
Most of my fellow cleantech VCs came to this field from some other domain – often semiconductors or telecom – and brought their pattern recognition biases along with them. The question I found myself asking was “What if everyone’s biases are wrong?” What if we’re picking the wrong eighth graders?
Coming from a career in the tech analyst business, I wanted to find a fact-based way to answer the question, so I assembled a set of successful VC-backed start-ups and looked for what they had in common. I picked companies that:
- Had achieved unambiguous success, which I defined as an IPO on a major exchange. That’s far from a perfect criterion, I know, but at least it’s clear-cut.
- Went public after 2000, to rule out the boomlet of ’98-’99 energy IPOs (when the Internet bubble’s rising tide lifted all boats).
- Were backed by institutional VC. Note that the majority of public cleantech companies have, in fact, not been venture-funded.
As of today, this sample consists of 18 companies:
(Doubtless there are errors in this data, so please point them out in the comments and I’ll make corrections in a batch. To pre-empt one item, however, note that I included predecessor companies in each firms’ history, which explains First Solar’s founding date.)
What can we learn from this? The average NBA draft pick of cleantech:
- Raised $122 million in equity financing, which excludes grants and debt. The distribution is pretty broad, but I’d note that if you remove Q-Cells and REC as special cases, the floor is ~ $30MM. If a new business plan poses a lower lifetime cash requirement, there should be an airtight argument to justify that claim.
- Went public at a ~ $900 million valuation, also with a broad distribution. If you assumed that investors owned, say, 80% of these companies at the IPO, the lot would have delivered a 5.9x return on capital invested.
- Took 8.3 years from founding to IPO. If you’re signing up to build a cleantech winner, reserve a decade. Note, however, that this elapsed time has shortened for companies that have gone public since 2010, where it averages 6.7 years. Start-ups in this later group received venture financing either right at their founding or soon after it, in contrast to earlier companies which often bootstrapped themselves for years before taking venture capital.
- Survived a 1-in-50 success rate. These 18 companies received their first venture investment between 1995 and 2007. A quick VentureSource search indicates 986 seed/Series A rounds done in cleantech during that period. While there are doubtless further successes to come, particularly from start-ups funded in the later years, the yield so far is 18 / 986 or a 1.8% of start-ups funded.
If we include some financial metrics, we learn a bit more. The average cleantech winner also:
- Went public on $72 million in revenue the prior year. With a couple of outliers (SemiLEDs and Gevo), the revenue floor for an IPO has been around $30 million since 2007. This has led to price-to-revenue valuations at IPO in the double digits, transcending their category comparables (for example, A123Systems is still at 4x P/S today despite two tough years, while incumbent battery-makers Exide and Enersys sit well under 1x). Winning cleantech start-ups get valued like high-growth tech companies, not like their incumbent peers, so the latter haven’t informed IPO valuations.
- Was unprofitable at IPO. Only four out of 18 companies – Q-Cells, REC, Solarfun, and Yingli, all in solar – showed an operating profit in the fiscal year before they filed. That situation remained unchanged in the year of the IPO itself, where most companies’ losses widened rather than narrowed.
This analysis tells us what the NBA draft looked like, but it doesn’t say anything about the eighth graders. To learn about them, we need to do some primary research. So I talked to as many people as I could who were familiar with these 18 companies at their earliest stages, and asked them a simple question: “At the time of the seed/Series A fundraise, how would you have rated [company X] on its technology, its market, and its team – great, middling, or unfavorable?”
For each start-up, I strove to speak with at least one investor who did the seed/Series A deal as well as at least one who saw it and passed; however, for many companies I couldn’t pull this off – so let me emphasize that there’s a heaping helping of subjectivity here. With that caveat in place, here were my results:
- Technology doesn’t correlate with success. At the timing of early-stage financing, only about one-third of these companies were real technology leaders with strong, differentiated IP (think Evergreen Solar in 1994). If you made picks based on technology alone, you’d have ruled out most of these companies.
- Market attractiveness was anti-correlated. Eight of these 18 firms faced unattractively small markets early on: Demand response was hardly a hot category when EnerNOC and Comverge formed in 2003, electric vehicles evoked little more than the EV-1’s failure at Tesla’s 2002 founding, and Reagan took the solar panels off the White House two years after First Solar’s predecessor Glasstech started up. Another six firms faced middling markets that were large in absolute terms but exhibited some deal-killing attribute, like low/volatile category margins (chemicals, fuels) or ruthless Chinese competition (batteries, LEDs). In most cases, the bit-flip from an unattractive market to an attractive one was driven by regulation (feed-in tariffs for solar, forward capacity markets etc. for demand response, and subsidies like the Renewable Fuels Standard for biofuels).
- Team matters most. The best predictor of success for this group was a killer team, present from the outset in a majority of these companies. (From my interviews, only one of the 18 was a “we’ll fund if the CEO gets replaced” situation.) The most important observation for me is that, most of the time, the founding CEO was the same one who rang the stock exchange bell years later: Eleven out of 18 never changed CEOs, two started life without any CEO and added one along the way (in both cases the founders stayed on), and only five changed leadership midstream. I frequently hear some of my energy VC peers say that there’s so little executive talent in this sector, replacement CEOs must be recruited as a matter of course; the facts don’t support that view.
So – faced with the daunting task of predicting cleantech’s NBA draft eight years hence – what am I looking for?
I’m looking for a great team – people who can defy intimidating odds and who show, rather than tell, how they will shape the world to match their will. I accept that additions will be made over time, but I have to believe that the people in front of me can drive a very large outcome in the roles they’re in now. I don’t care whether the market they’re selling into is big today, but I need to be compelled by their vision of what will change to make it attractive during the period of investment. (That forcing function is probably regulatory.)
Finally, no matter how impressive the technology is, I won’t compromise on the people (although I’m likely to accept a tradeoff in the opposite direction).
That’s just my take, and I’m fully aware that the error bars around this analysis are huge. But if you agree with any of it, it follows that the best thing cleantech investors can do is attract the brightest minds to this domain. This should be the greatest creative and collaborative focus of our fledgling community.
