It took me a week or so to get to it, but in this post I’ll take a dive into the Hortonworks S-1 filing in support of a proposed initial public offering (IPO) of their stock.
While Hadoop and big data are unarguably huge trends driving the industry and while the future of Hadoop looks very bright indeed, on reading the Hortonworks S-1, the reader is drawn to the inexorable conclusion that it’s hard to make money in open source, or more crassly, it’s hard to make money when you give the shit away.
This is a company that, in the past three quarters, lost $54M on $33M of support/services revenue and threw in $26M in non-recoverable (i.e., donated) R&D atop that for good measure.
Let’s take it top to bottom:
- They have solid bankers: Goldman Sachs, Credit Suisse, and RBC are leading the underwriting with specialist support from Pacific Crest, Wells Fargo, and Blackstone.
- They have an awkward, jargon-y, and arguably imprecise marketing slogan: “Enabling the Data-First Enterprise.” I hate to be negative, but if you’re going to lose $10M a month, the least you can do is to invest in a proper agency to make a good slogan.
- Their mission is clear: “to establish Hadoop as the foundational technology of the modern enterprise data architecture.”
- Here’s their solution description: “our solution is an enterprise-grade data management platform built on a unique distribution of Apache Hadoop and powered by YARN, the next generation computing and resource management framework.”
- They were founded in 2011, making them the youngest company I’ve seen file in quite some years. Back in the day (e.g., the 1990s) you might go public at age 3-5, but these days it’s more like age 10.
- Their strategic partners include Hewlett-Packard, Microsoft, Rackspace, Red Hat, SAP, Teradata, and Yahoo.
- Business model: “consistent with our open source approach, we generally make the Hortonworks Data Platform available free of charge and derive the predominant amount of our revenue from customer fees from support subscription offerings and professional services.” (Note to self: if you’re going to do this, perhaps you shouldn’t have -35% services margins, but we’ll get to that later.)
- Huge market opportunity: “According to Allied Market Research, the global Hadoop market spanning hardware, software and services is expected to grow from $2.0 billion in 2013 to $50.2 billion by 2020, representing a compound annual growth rate, or CAGR, of 58%.” This vastness of the market opportunity is unquestioned.
- Open source purists: “We are committed to serving the Apache Software Foundation open source ecosystem and to sharing all of our product developments with the open source community.” This one’s big because while it’s certainly strategic and it certainly earns them points within the Hadoop community, it chucks out one of the better ways to make money in open source: proprietary versions / extensions. So, right or wrong, it’s big.
- Headcount: The company has increased the number of full-time employees from 171 at December 31, 2012 to 524 at September 30, 2014
Before diving into the financials, let me give readers a chance to review open source business models (Wikipedia, Kellblog) if they so desire, before making the (generally true but probably slightly inaccurate) assertion: the only open source company that’s ever made money (at scale) is Red Hat.
Sure, there have been a few great exits. Who can forget MySQL selling to Sun for $1B? Or VMware buying SpringSource for $420M? Or RedHat buying JBoss for $350M+? (Hortonworks CEO Rob Bearden was involved in both of the two latter deals.) Or Citrix buying XenSource for $500M?
But after those deals, I can’t name too many others. And I doubt any of those companies was making money.
In my mind there are a two common things that go wrong in open source:
- The market is too small. In my estimation open source compresses the market size by 10-20x. So if you want to compress the $30B DBMS market 10x, you can still build several nice companies. However, if you want to compress the $1B enterprise search market by 10x, there’s not much room to build anything. That’s why there is no Red Hat of Lucene or Solr, despite their enormous popularity in search. For open source to work, you need to be in a huge market.
- People don’t renew. No matter which specific open source business model you’re using, the general play is to sell a subscription to <something> that complements your offering. It might be a hardened/certified version of the open source product. It might be additions to it that you keep proprietary forever or, in a hardcover/paperback analogy, roll back into the core open source projects with a 24 month lag. It might be simply technical support. Or, it might be “admission the club” as one open source CEO friend of mine used to say: you get to use our extensions, our support, our community, etc. But no matter what you’re selling, the key is to get renewals. The risk is that the value of your extensions decreases over time and/or customers become self-sufficient. This was another problem with Lucene. It was so good that folks just didn’t need much help and if they did, it was only for a year or so.
So Why Does Red Hat work?
Red Hat uses a professional open source business model applied to primarily two low-level infrastructure categories: operating systems and later middleware. As general rules:
- The lower-level the category the more customers want support on it.
- The more you can commoditize the layers below you, the more the market likes it. Red Hat does this for servers.
- The lower-level the category the more the market actually “wants” it standardized in order to minimize entropy. This is why low-level infrastructure categories become natural monopolies or oligopolies.
And Red Hat set the right price point and cost structure. In their most recent 10-Q, you can see they have 85% gross margins and about a 10% return on sales. Red Hat nailed it.
But, if you believe this excellent post by Andreessen Horowitz partner Peter Levine, There Will Never Be Another Red Hat. As part of his argument Levine reminds us that while Red Hat may be a giant among open source vendors, that among general technology vendors they are relatively small. See the chart below for the market capitalization compared to some megavendors.
Now this might give pause to the Hadoop crowd with so many firms vying to be the Red Hat of Hadoop. But that hasn’t stopped the money from flying in. Per Crunchbase, Cloudera has raised a stunning $1.2B in venture capital, Hortonworks has raised $248M, and MapR has raised $178M. In the related Cassandra market, DataStax has raised $190M. MongoDB (with its own open source DBMS) has raised $231M. That’s about $2B invested in next-generation open source database venture capital.
While I’m all for open source, disruption, and next-generation databases (recall I ran MarkLogic for six years), I do find the raw amount of capital invested pretty crazy. Yes, it’s a huge market today. Yes, it’s exploding as do data volumes and the new incorporation of unstructured data. But we will be compressing it 10-20x as part of open-source-ization. And, given all the capital these guys are raising – and presumably burning (after all, why else would you raise it), I can assure you that no one’s making money.
Hortonworks certainly isn’t — which serves as a good segue to dive into the financials. Here’s the P&L, which I’ve cleaned up from the S-1 and color-annotated.
- $33M in trailing three quarter (T3Q) revenues ($41.5M in TTM, though not on this chart)
- 109% growth in T3Q revenues
- 85% gross margins on support
- Horrific -35% gross margins on services which given the large relative size of the services business (43% of revenues) crush overall gross margins down to 34%
- More scarily this calls into question the veracity of the 85% subscription gross margins — I recall reading in the S-1 that they current lack VSOE for subscription support which means that they’ve not yet clearly demonstrated what is really support revenue vs. professional services revenue. [See footnote 1]
- $26M in T3Q R&D expense. Per their policy all that value is going straight back to the open source project which begs the question will they ever see return on it?
- Net loss of $86.7M in T3Q, or nearly $10M per month
Here are some other interesting tidbits from the S-1:
- Of the 524 full-time employee as of 9/30/14, there are 56 who are non-USA-based
- CEO makes $250K/year in base salary cash compensation with no bonus in FY13 (maybe they missed plan despite strong growth?)
- Prior to the offering CEO owns 6.8% of the stock, a pretty nice percentage, but he was a kind-of a founder
- Benchmark owns 18.7%
- Yahoo owns 19.6%
- Index owns 9.5%
- $54.9M cash burn from operations in T3Q, $6.1M per month
- Number of support subscription customers has grown from 54 to 233 over the year from 9/30/13 to 9/30/14
- A single customer represented went from 47% of revenues for the T3Q ending 9/30/13 down to 22% for the T3Q ending 9/30/14. That’s a lot of revenue concentration in one customer (who is identified as “Customer A,” but who I believe is Microsoft based on some text in the risk factors.)
Here’s a chart I made of the increase in value in the preferred stock. A ten-bagger in 3 years.
One interesting thing about the prospectus is they show “gross billings,” which is an interesting derived metric that financial analysts use to try and determine bookings in a subscription company. Here’s what they present:
While gross billings is not a bad stab at bookings, the two metrics can diverge — primarily when the duration of prepaid contracts changes. Deferred revenue can shoot up when sales sells longer prepaid contracts to a given number of customers as opposed to the same-length contract to more of them. Conversely, if happy customers reduce prepaid contract duration to save cash in a downturn, it can actually help the vendor’s financial performance (they will get the renewals because the customer is happy and not discount in return for multi-year), but deferred revenue will drop as will gross billings. In some ways, unless prepaid contract duration is held equal, gross billings is more of a dangerous metric than anything else. Nevertheless Hortonworks is showing it as an implied metric of bookings or orders and the growth is quite impressive.
Sales and Marketing Efficiency
Let’s now look at sales and marketing efficiency, not using the CAC which is too hard to calculate for public companies but using JMP’s sales and marketing efficiency metric = gross profit [current] – gross profit [prior] / S&M expense [prior].
On this metric Hortonworks scores a 41% for the T3Q ended 9/30/14 compared to the same period in 2013. JMP considers anything above 50% efficient, so they are coming in low on this metric. However, JMP also makes a nice chart that correlates S&M efficiency to growth and I’ve roughly hacked Hortonworks onto it here:
I’ll conclude the main body of the post by looking at their dollar-based expansion rate. Here’s a long quote from the S-1:
Dollar-Based Net Expansion Rate. We believe that our ability to retain our customers and expand their support subscription revenue over time will be an indicator of the stability of our revenue base and the long-term value of our customer relationships. Maintaining customer relationships allows us to sustain and increase revenue to the extent customers maintain or increase the number of nodes, data under management and/or the scope of the support subscription agreements. To date, only a small percentage of our customer agreements has reached the end of their original terms and, as a result, we have not observed a large enough sample of renewals to derive meaningful conclusions. Based on our limited experience, we observed a dollar-based net expansion rate of 125% as of September 30, 2014. We calculate dollar-based net expansion rate as of a given date as the aggregate annualized subscription contract value as of that date from those customers that were also customers as of the date 12 months prior, divided by the aggregate annualized subscription contract value from all customers as of the date 12 months prior. We calculate annualized support subscription contract value for each support subscription customer as the total subscription contract value as of the reporting date divided by the number of years for which the support subscription customer is under contract as of such date.
This is probably the most critical section of the prospectus. We know Hortonworks can grow. We know they have a huge market. We know that market is huge enough to be compressed 10-20x and still have room to create a a great company. What we don’t know is: will people renew? As we discussed above, we know it’s one of the great risks of open source
Hortonworks pretty clearly answers the question with “we don’t know” in the above quote. There is simply not enough data, not enough contracts have come up for renewal to get a meaningful renewal rate. I view the early 125% calculation as a very good sign. And intuition suggests that — if their offering is quality — that people will renew because we are talking low-level, critical infrastructure and we know that enterprises are willing to pay to have that supported.

In the appendix below, I’ll include a few interesting sections of the S-1 without any editorial comments.
A significant portion of our revenue has been concentrated among a relatively small number of large customers. For example, Microsoft Corporation historically accounted for 55.3% of our total revenue for the year ended April 30, 2013, 37.8% of our total revenue for the eight months ended December 31, 2013 and 22.4% of our total revenue for the nine months ended September 30, 2014. The revenue from our three largest customers as a group accounted for 71.0% of our total revenue for the year ended April 30, 2013, 50.5% of our total revenue for the eight months ended December 31, 2013 and 37.4% of our total revenue for the nine months ended September 30, 2014. While we expect that the revenue from our largest customers will decrease over time as a percentage of our total revenue as we generate more revenue from other customers, we expect that revenue from a relatively small group of customers will continue to account for a significant portion of our revenue, at least in the near term. Our customer agreements generally do not contain long-term commitments from our customers, and our customers may be able to terminate their agreements with us prior to expiration of the term. For example, the current term of our agreement with Microsoft expires in July 2015, and automatically renews thereafter for two successive twelve-month periods unless terminated earlier. The agreement may be terminated by Microsoft prior to the end of its term. Accordingly, the agreement with Microsoft may not continue for any specific period of time.

We do not currently have vendor-specific objective evidence of fair value for support subscription offerings, and we may offer certain contractual provisions to our customers that result in delayed recognition of revenue under GAAP, which could cause our results of operations to fluctuate significantly from period-to-period in ways that do not correlate with our underlying business performance.
In the course of our selling efforts, we typically enter into sales arrangements pursuant to which we provide support subscription offerings and professional services. We refer to each individual product or service as an “element” of the overall sales arrangement. These arrangements typically require us to deliver particular elements in a future period. We apply software revenue recognition rules under U.S. generally accepted accounting principles, or GAAP. In certain cases, when we enter into more than one contract with a single customer, the group of contracts may be so closely related that they are viewed under GAAP as one multiple-element arrangement for purposes of determining the appropriate amount and timing of revenue recognition. As we discuss further in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates—Revenue Recognition,” because we do not have VSOE for our support subscription offerings, and because we may offer certain contractual provisions to our customers, such as delivery of support subscription offerings and professional services, or specified functionality, or because multiple contracts signed in different periods may be viewed as giving rise to multiple elements of a single arrangement, we may be required under GAAP to defer revenue to future periods. Typically, for arrangements providing for support subscription offerings and professional services, we have recognized as revenue the entire arrangement fee ratably over the subscription period, although the appropriate timing of revenue recognition must be evaluated on an arrangement-by-arrangement basis and may differ from arrangement to arrangement. If we are unexpectedly required to defer revenue to future periods for a significant portion of our sales, our revenue for a particular period could fall below our expectations or those of securities analysts and investors, resulting in a decline in our stock price

We generate revenue by selling support subscription offerings and professional services. Our support subscription agreements are typically annual arrangements. We price our support subscription offerings based on the number of servers in a cluster, or nodes, data under management and/or the scope of support provided. Accordingly, our support subscription revenue varies depending on the scale of our customers’ deployments and the scope of the support agreement.
Our early growth strategy has been aimed at acquiring customers for our support subscription offerings via a direct sales force and delivering consulting services. As we grow our business, our longer-term strategy will be to expand our partner network and leverage our partners to deliver a larger proportion of professional services to our customers on our behalf. The implementation of this strategy is expected to result in an increase in upfront costs in order to establish and further cultivate such strategic partnerships, but we expect that it will increase gross margins in the long term as the percentage of our revenue derived from professional services, which has a lower gross margin than our support subscriptions, decreases.

Deferred Revenue and Backlog
Our deferred revenue, which consists of billed but unrecognized revenue, was $47.7 million as of September 30, 2014.
Our total backlog, which we define as including both cancellable and non-cancellable portions of our customer agreements that we have not yet billed, was $17.3 million as of September 30, 2014. The timing of our invoices to our customers is a negotiated term and thus varies among our support subscription agreements. For multiple-year agreements, it is common for us to invoice an initial amount at contract signing followed by subsequent annual invoices. At any point in the contract term, there can be amounts that we have not yet been contractually able to invoice. Until such time as these amounts are invoiced, we do not recognize them as revenue, deferred revenue or elsewhere in our consolidated financial statements. The change in backlog that results from changes in the average non-cancelable term of our support subscription arrangements may not be an indicator of the likelihood of renewal or expected future revenue, and therefore we do not utilize backlog as a key management metric internally and do not believe that it is a meaningful measurement of our future revenue.

We employ a differentiated approach in that we are committed to serving the Apache Software Foundation open source ecosystem and to sharing all of our product developments with the open source community. We support the community for open source Hadoop, and employ a large number of core committers to the various Enterprise Grade Hadoop projects. We believe that keeping our business model free from architecture design conflicts that could limit the ultimate success of our customers in leveraging the benefits of Hadoop at scale is a significant competitive advantage.

International Data Corporation, or IDC, estimates that data will grow exponentially in the next decade, from 2.8 zettabytes, or ZB, of data in 2012 to 40 ZBs by 2020. This increase in data volume is forcing enterprises to upgrade their data center architecture and better equip themselves both to store and to extract value from vast amounts of data. According to IDG Enterprise’s Big Data Survey, by late 2014, 31% of enterprises with annual revenues of $1 billion or more expect to manage more than one PB of data. In comparison, as of March 2014 the Library of Congress had collected only 525 TBs of web archive data, equal to approximately half a petabyte and two million times smaller than a zettabyte.

 Thinking more about this, while I’m not an accountant, I think the lack of VSOE has the following P&L impact: it means that in contracts that mix professional services and support they must recognize all the revenue ratably over the contract. That’s fine for the support revenue, but it should have the effect of pushing out services revenue, artificially depressing services gross margins. Say, for example you did a $240K that was $120K of each. The support should be recognized at $30K/quarter. However, if the consulting is delivered in the first six months it should be delivered at $60K/quarter for the first and second quarters and $0 in the third and fourth. Since, normally, accountants will take the services costs up-front this should have the effect of hurting services by taking the costs as delivered but by the revenue over a longer period.
