A big part of investment is pattern recognition. Of course they try to understand what people are doing but that only gets you so far. Ideally, you would want to be able to learn from your previous decisions and improve on your process. If you have real data and a way of using it for more insight then you can make much better decisions.

Their version of "pattern recognition" is just hopeless for what they are trying to do. E.g., how to use pattern recognition in the industry of leading edge military aviation to evaluate what Kelly Johnson said about building an airplane that would go at Mach 3+ and 80,000+ feet for 2000+ miles without refueling? Can't do it. Instead have to look at the mathematics, engineering, etc., especially a special engine just…

"Net, Silicon Valley venture capital just absolutely, positively, flatly doesn't have even as much as a weak little hollow hint of a tiny clue about how to do or evaluate original, exceptional, powerful, valuable information technology projects. Sorry 'bout that."

- Your use of hyperbole is amazing. The original point of venture capital was to "aid in the development of new or existing businesses into companies of stature and importance". Venture capital arose after world war 2 when banks wouldn't bankroll some of the businesses and new ideas that were coming out. Since then it could be argued that VCs direction has changed to investing the 3rd party pooled money into businesses that are employing some novel technology or processes. VCs typically have employees who are familiar with industries, business, and / or technologies to help identify candidate investments as well as to help said investments to flourish. Finally to brush the successes of venture capital over the years in IT projects is just disingenuous. VCs had quite a bit to do with DEC, Fairchild, the whole damned semi conductor business, and the expansion of the computer industry. Was a lot of it on the backs of other projects and companies? Of course. DARPA, Xerox, etc. played HUGE roles in the advancement of technology.

I wonder if this could act as a negative filter for good programmers. Who worth their salt is going to invest 3 hours of their time just to submit a resume? Wouldn't you want to talk to the employer first to see if they're a good fit? In a tight labor market, people willing to do this are more desperate than others. So it's going to filter for desperate developers who passed a 3 hour basic skills test. Old fashioned…

Well, empirically we're getting quite a lot of people attempting it! :) Three hours is pretty lenient (you could blaze through it in less time), though the last question is challenging. We think the questions are kind of fun as well. Without something like this we'd just have 100s-1000s of unstructured resumes in different formats to rank against each other. This process is more fair and (IMO) allows someone without…

The questions were pretty good, because they were close to the real world and you couldn't google them so easily. The programming tasks were rather unbalanced. The first two were super easy, while you can easily get stuck on the last one, even as a good programmer. I knew that I wouldn't be able to answer it today, so I skipped it after a short while. If I'd plan such a test, I'd try to get an example of the structure and comprehensibility of my future employees work.

> Second, I would suggest that a cold email is probably the worst way to approach ANY VC.

Sorry they are having trouble handling e-mail. It's an old technology and relatively easy to work with. E-mail is just simple text, much like HN posts. Such simple text works great at HN. Too bad the 'high tech' A16Z can't work with simple text.

With all their efforts to find good investment opportunities, they might just look at their incoming e-mail and then read it. But your statement seems to indicate that they want to ignore e-mail, and that does appear to be the case. Ignoring e-mail is bizarre, but they are free to do so.

For the rest of your post, you miss the big, huge point: As is commonly asserted, one of the better parts of a new project is new technology that is powerful and valuable, intellectual property, 'secret sauce', with a high technological barrier to entry, for solving a big, important problem. Such technology, at least in my interest, is definitely just in the service of making money, the green kind.

If a project claims to be able to solve a huge problem so far unsolved, that many others have tried unsuccessfully to solve, then a crucial, early question for interest in the project is what the heck is the crucial 'secret sauce' that enables the solution, that lets this project do what prior projects could not?

Again, of course, the purpose of and interest in the secret sauce is making money.

I can 100% absolutely, positively guarantee you that one can write a very carefully written e-mail with a project to solve what is clearly a huge problem with overwhelming and obvious evidence that a company solving this problem will be worth $x billion for x high enough to be historic, and outline some of the crucial secret sauce and have A16Z totally ignore the contact. Call them on the phone and tell them about the e-mail, and they will refuse to dig it out of their inbox and look at it. They will say, "send it again", and someone might say, "I don't think that we can do business along these lines.". "Send it again" is just a manipulation to insult entrepreneurs by a firm that does not value contacts from entrepreneurs. If I get rich, A16Z won't participate.

The importance of their abilities to evaluate new, powerful, valuable technology is just that such evaluation is just crucial for any project where one of the main features is such technology. As I made clear, thankfully for US national security, the US DoD has long been excellent at evaluating new technology. If the DoD sees a significant problem and someone comes up with some new, powerful technology for the first or a much better solution, then the DoD will listen and, really, in my experience, for a good case, proceed. My experience is that apparently mostly A16Z won't; they won't even look at their e-mail or listen on the phone. Heck, just finding their phone number takes some effort.

Biomedical VCs will evaluate such technology. Information technology (IT) VCs won't. Why? The IT VCs just don't want to care about such technology. Instead they want to make money other ways. As posted by Fred Wilson at his AVC.com some months ago, on average the IT VCs are doing poorly. Still they insist on not even evaluating new technology. Their feet are locked solidly in concrete with their eyes and ears closed, refusing to pay attention to e-mail and phone calls.

Really the IT VCs believe that all there is to the 'technology' in IT is little more than routine software development. On average, this attitude fits with the past. But so far, e.g., from A16Z there are only about 15 projects a year that deserve a Series A. And it's easy to see that there are only a few Googles or Facebooks each decade. So, looking at the average projects in the past is a hopelessly poor way to find the 15 Series A projects for this year or the next Google this decade. Still, A16Z won't read their e-mail to find such projects.

The situation is fairly clear: The IT VCs want to see traction, up and to the right. Then they want to invest for the big build out and the rapid growth on the way to going public. Sometimes they make money doing this; on average essentially they don't.

For your

> - They're not looking for MD physicians as the portfolio companies have the technical expertise.

No. My remark was in the context of the project of their OP and recruiting. For the goals of that project mentioned in this thread, my analogy with an MD is correct -- they will need one. But they are not recruiting for one. Instead they are recruiting for nurse practitioners. E.g., you mentioned cluster analysis. So, as I explained in terms of the SR-71, could not evaluate that project by cluster analysis of the then history of military aviation and, instead, need to look at the engineering details Kelly Johnson was proposing. Similarly, cluster analysis stands to be nearly hopeless for predicting the future of IT projects and, instead, must look at the details of the projects. It does appear that the project of the OP missed this point.

> - Do you want a cookie?

It's really tough to communicate with someone who works not to understand. Then even something simple won't come across. The point was, in really simple, baby talk terms, (1) the goal if IT projects is to make money. (2) One of the best possible parts of a new IT project is new, powerful, valuable, technology to provide the first good or a much better solution with a high technological barrier to entry to a big problem where such a solution will be very valuable. (3) To evaluate such a project early on, it is just crucial to evaluate the technology. (4) My background shows that I am competent both to create such technology and to evaluate it, and, more generally understand the potential of such technology in projects in business.

From that background, no, I don't want a cookie. Instead it would be good if A16Z would read their e-mail and evaluate projects including any new, powerful, valuable technology. It's not about cookies. It's about evaluating projects.

> - I'm pretty sure that's not the case with you. I'm pretty sure that even if it was shown they're beating even 80% of other VCs you would still be hyper critical of their technical evaluation skills.

Sure. However much money they are making, they shouldn't pass up making much more. The US DoD doesn't do this. Neither does the NIH or the US pharmaceutical industry. People in US national security, biotechnology, and research in mathematics, statistics, and most areas of engineering would say that refusing to evaluate technology must be playing with mice and ignoring elephants.

Besides, US VC ROI is so bad that being better than 80% of the US VC firms might well still mean just losing money for the LPs.

> It's nice that you want to brush how most VCs are judged as successes or not (by the performance of their portfolio) as secondary in comparison to what you want to judge them by.

No, I judge them by making money. Their business they have chosen is IT VC. Then if they refuse to evaluate technology, then they are at high risk of missing out on the next big win of the next decade. Why is this clear? Not really because 'secret sauce' played such a big role in most or even any of the big wins in IT in the past 20 years but because of the overwhelming power of 'secret sauce' demonstrated in US national security and the biomedical industry. The NSF funds research in the mathematical sciences and more mathematical ares of engineering for a very good reason; but Silicon Valley (SV) believes that no business value can come from that work. SV is wrong. They may be very badly wrong, e.g., miss a few new Googles.

Hmm. Sorry, guys, considering just routine software is a huge handicap in going "after the big problems".

> We believe this is an incredibly exciting time to be a technology investor.

Okay, here they say "technology" and not just routine software. But do they want to evaluate technology? Apparently not. Heck, they won't even read their e-mail.

> smartphone users are expected to grow from 1.5 billion today to five billion in the coming years.

There they go thinking of sectors again. Maybe with all those new users there will be new problems to solve and valuable companies to solve them. Otherwise they are talking a "rising tide raises all the boats" growth of a factor of only a little over 3 in 5 years, and that's not very impressive. Broadly, super tough to get venture returns from growth of a sector and, instead, need to get such returns from growth of individual projects, maybe in a rapidly growing sector, maybe not. For such projects, 'secret sauce' technology can be one of the best advantages.

> These entrepreneurs care enough about all aspects of their product/service that they want (or need) to innovate in all the areas that touch it.

So, now they also want to "innovate". That's what I'm talking about where you thought it was just a cookie. But such innovation needs evaluation. Of course, if A16Z just looks at the traction, they they can talk about software, technology, and innovation, refuse to evaluate anything technical, and just count monthly uniques, page views, ComScore data, etc. But A16Z says that they are in "multi-stage" investing, and waiting for traction now risks being quite late, too late.

Too late? Just do a little of the arithmetic all of use here at HN can easily do: Pick an Internet connection with, say, 25 Mbps upload bandwidth. Pick a server with, say, an 8 core processor at 4.0 GHz and 64 bit addressing with 32 GB of ECC main memory and an armload of 4 GB disk drives. We're talking $1500 in parts. Send Web pages for 400,000 bits per page. Send 5 simple ads per page. Get enough users to half fill that upload bandwidth 24 x 7. Have the software fast enough and scalable enough that just one or a few such servers can handle the load. Assume $2 per 1000 ads displayed. Okay, let's multiply it out:

So send

25 * 106 / ( 2 * 400,000 ) = 31.250

pages a second.

Then revenue of

31.250 * 2 * 5 * 3600 * 24 * 30 / 1000 = 810,000

dollars a month.

Now, just why does such a project want to accept seed or Series A funding?

Has any project successfully thought this way? Sure: Early on Plenty of Fish was just one guy, two old Dell servers, ads just from Google, and $10 million a year in revenue.

> If we are right that software is in fact eating the world,

There is considerable question if just routine software will yield venture returns. One reason is the low barrier to entry. E.g., China had no trouble doing something like Google. Neither did Microsoft. A16Z seems to accept low technological barriers to entry; that has to be a big mistake, even if they are making money. Heck, my local pizza guy is making money.

I'm failing to see why an entrepreneur with a good project should waste time with A16Z who hide their phone number, refuse to read their e-mail, and won't and even can't evaluate crucial secret sauce technology.

For good exploitation of technology, what you are describing is not nearly good enough. The IT VCs need very much to up their game to whole new levels. They need, say, to be able to do or at least direct evaluations of anything that arrives in their e-mail in IT that might make a big pot of money, and they can't and won't do that.

I guess to reiterate my point: once you've done web development for a couple years, coding most websites is less about solving new problems and more about applying known solutions.

To reiterate how this point relates to the question of coding interviews: in as much as they don't test for lots of known solutions, and the ability to apply known solutions quickly, they aren't filtering for productive coders.

"But your statement seems to indicate that they want to ignore e-mail, and that does appear to be the case. Ignoring e-mail is bizarre, but they are free to do so."

- Allow me to be clear. They are not ignoring e-mail. They are selectively choosing what they will spend their time on. They have (apparently) chosen not to spend time on your idea. Perhaps in the future you should make your emails more clear, you should be more persuasive, and your idea more compelling.

"For the rest of your post, you miss the big, huge point"

- Oh I get it. I just have quite a bit of contradictory evidence in how they work. Let me paint a picture for you. Perhaps you've heard of Prof. Cheriton of Stanford. He's written a publication or two and invested in a successful startup or two. He invested in a startup called AsterData. So did A16Z. Do you see how that works? They don't necessarily need the deep technical expertise within their team. They can rely on others to do that. Similarly, you might recall me mentioning that cold email is not the best course. If the technical idea you're suggesting is so revolutionary, you should have little to no problem having a well-respected professor get you an introduction.

No, I'm just reporting some strong evidence that they just don't read their e-mail. Or, to be more clear, apparently essentially all information technology (IT) VCs will just ignore an e-mail message saying (generic version; real version with specifics):

(1) Here is the problem we are attacking. So far it is easy to see that there is no good solution. Fairly clearly a good solution will be of high interest to over 80% of all the Internet users, work station down to smart phone, in the world.

(2) The main reason the problem has remained unsolved is that knowing how to solve the problem is a challenge. The team has a new, unique, powerful, valuable, rock solid solution that has a high technological barrier to entry.

(3) Monetization? With a few billion unique users a month, for a first cut, just run ads. For more, there is an aspect of the project that permits some especially effective ad targeting with especially good protection of user privacy.

(4) The crucial core software implementing the technology is production quality and scalable. The rest is just an especially simple front-end Web site, nearly done.

(5) Team qualifications in business, research, and software are high.

Then with 1-5, they will just ignore the contact. No response. No questions. Nothing. They just ignore it. From the claims there, we're talking $100+ billion exit value; they just ignore it. No response; just toss it into the bit bucket.

Look, we're talking a billion or more unique visitors a month and an exit value north of $100 billion, and they have no response at all. Strong evidence that they just ignore their e-mail. Leave a $20 on a sidewalk; a guy walks by; the $20 is still there; conclusion, he didn't see the $20. Or, the VC firm just didn't see the e-mail.

One reason is, US IT VCs just have never seen any such thing, that is, an IT start up where what is crucial is the 'secret sauce' technology to solve the big problem. Instead, they pursue only other ways of making money and where the technology is essentially just routine software. US IT VCs and A16Z just will not give any value to (that is, won't spend time to investigate) results of research in IT -- the DoD is awash in valuable results of such research; biotech VC will take research seriously; but US IT VCs haven't seen any big business success from such research, don't really understand research or how to evaluate it, want to pursue other ways of making money, and want just to ignore anything based on research. They just want to f'get about research. That is the obvious explanation.

Since the US IT VCs are just determined to ignore research, the flip side of that is an advantage for any project with some good research.

Net, they don't read their e-mail and won't evaluate technology.

> - I would suggest they're not having trouble handling email...their filtering is working just fine. You would appear to have trouble handling rejection (at least I would infer that)

No, the situation is just as I said: The evidence is overwhelmingly strong that they just refuse to read e-mail from someone they don't know. That's their choice.

> They don't necessarily need the deep technical expertise within their team.

Yes they do or they are at risk of missing out on possibly some of the best projects. As I made clear, for the past 10-20 years, information technology (IT) VCs have not seen big successes based on anything at the level of publishable technical research. So, they just f'get about thinking about or evaluating such work. Again, the track record and promise of such research is from DoD, NSF, NIH, etc., not IT entrepreneurs over the past 10-20 years.

Research based projects will likely remain only a tiny fraction of what US IT VCs get in their inbox, but such projects are a good bet for a few $100+ exits over the next decade. Considering how few such successes there are, ignoring such projects, especially with the example of DoD, is foolish.

For Cheriton, they were not reading just some e-mail or investing in the technology; instead, they already knew the professor and were investing in him. But professors are not nearly the only people who can do research.

> - Allow me to be clear. They are not ignoring e-mail.

No, flatly they are ignoring e-mail. Write them something short, clear, and astounding, and they just ignore it, won't read it, won't respond at all. Maybe they want an introduction. Maybe they want only other means of selecting entrepreneurs. Maybe they just are having fun pissing off entrepreneurs. Maybe they are busy enough with what they are doing now. Maybe whatever, but they ignore e-mail. Sorry 'bout that, but they do.

> - You seem to keep missing the obvious point of perhaps they evaluated the technology you seem to be so bunched up about...and didn't care for it.

Nonsense. For the technology in question, there is likely and apparently only one person in the world who knows it. Send A16Z a high level view, and they ignore the communications. They make no attempt to get the details of the technology and evaluate it. It's simple: They just will not get involved in evaluating new technology.

> - Perhaps they evaluated and weren't impressed. Or is that impossible?

It is impossible. They can't have even as much as a weak little hollow hint of a tiny clue about anything about the crucial internals of the technology. They received only a business view of the power and value of the technology. For how it works, which is crucial for evaluating it, they don't know. To know they would have to do some due diligence. There is little hope that they could competently direct the due diligence.

Right. We're talking about A16Z. My point was in response to your figure of 80%: Likely a VC firm with ROI just better than 80% of the VC industry is still losing money for its LPs. In this case, even if A16Z has better ROI than 80% of VC firms, they might still be losing money. However, since they just raised $1.5 billion, I suspect that it appears that they are making money; since a lot of the old investments likely have yet to exit, it might be tough to know their ROI so far, but no doubt they had to show something good about ROI to raise $1.5 billion.

> Incorrect. What about Oculus for example?

I don't know that case well, but my superficial understanding is that the product was in production and selling and all a venture firm had to do was to evaluate the sales figures and the product itself without much concern for any crucial internals of the technology. Like I said, the US DoD, CIA, etc. funded the SR-71 when nearly it was was engineering on paper, and VCs would want to wait until the plane was flying successfully and then maybe pay for some of the jet fuel. US IT VCs just will not evaluate technical work just on paper; they won't do it. Maybe this situation is enforced by the LPs, but that is the situation. The story used to be that VCs could fund a project described on the back of a napkin, but now they just will not fund original technical work just on paper or even when the corresponding software is production quality and running. If some such project gets funded, then the reason was not just the technology and software but the reputation of the founder or some such. NSF, NIH, DARPA, Ph.D. committees, and peer-reviewed journals of original research will evaluate new work just on paper, but US IT VCs just will not. And, e-mail with any such connection with such research goes into the bit bucket, from their "filter" if they look at the e-mail at all.

We are in agreement: They just do not want to look at e-mail.

So be it.

The project in question, if it starts to work at all, will quickly generate revenue of $10,000, $40,000, ..., $800,000 a month starting with just a $1500 server and, for $1 million a month, using just a few such servers in a spare bedroom with some A/C in a window, a consumer Internet connection (that permits commercial usage), and a 200 A circuit breaker.

So, why jerk chains of VCs? For the project in question, it has long been the case that there has been no very good reason, although maybe just as 'reserve fuel' in case of some disaster. The main reason for my posts here are just to let the HN community know that A16Z and essentially all of US IT VC just will not take seriously descriptions of technical work in e-mail without an introduction, knowing the person, etc. For anyone with a background in doing projects inside a business, for US national security, or for academic research, this situation is just bizarre and has cost the founders of the project a lot of time although only some time ago. But the project moved forward on its own funding, and revenue with good free cash flow, plenty enough to grow capacity if usage does grow, seems quite near. So, for this project, to heck with VCs. But the time wasted in the past on VCs still hurts. And the HN audience should know some of the truth.
