I believe the first point is referring to investors who haven't put money into your company. If you aren't currently raising money, you shouldn't waste your time talking to investors. Raising money is a long process, and can't be done part time. Some might argue that meeting for coffee can help build a relationship with an investor, which would result in making raising easier in the future. However, if your company is worth investing in, these relationships shouldn't matter when it comes time to raise.

The second point is referring to your company's current investors. A monthly update let's those who have a vested interest know where you're at currently, and what you may need help with. Investors should be doing everything they can to help a company. That's why this relationship is important.


> If you're gearing up to raise money or need specific advice

(emphasis mine)

That part makes it seem like they are talking about current investors. How many random investors (that are not currently vested in your company) meet you for coffee and give you specific advice? Maybe this is just a Valley-specific thing?


We're essentially identifying patterns that occur in the voltage readout of two parallel sensors. Two different people, even if passing through without a gap, show enough of a difference in their pattern to tell them apart. It simply takes time to root out all of these granular edge cases.


Got it, thanks! Not sure what use cases you have already thought about but certainly see this being quite handy from a business perspective e.g. retailers can run real time customized offers/campaigns depending on the levels of density at their place to engage with the users better and improve overall experience (of course bottom line as well:)).


Like "reverse surge pricing"... free coffee until the place gets busy.


Exactly or maybe 20% discount on your favorite meal depending on the store/time of day/user profile etc. This can to some extent ensure the overall utilization of the retail store and thus profitability are improved. I'm pretty confident retailers wouldn't mind paying for this on a saas basis or some other similar model. This will also help on the user acquisition side as there's now a really cool incentive for downloading/using the app!


Yup! That's actually our model. I'm really excited to see what people do with the data

Love the webhooks idea, I can see users hooking into something like ifttt.


Generally, we give the hardware away for free (circumstance dependent). We'd prefer to monetize the data. We don't really want to build a company on $49.99 / mo. There are a lot of other players in that game. Here's a picture of the sensors if you're interested: http://i.imgur.com/zLUMAG8.jpg?1


We posted Density a while back when we used mac address tracking (https://news.ycombinator.com/item?id=7305097). We've since moved to a wirelessly connected door counter, would love some feedback.


Glad to see the change in methodology! I loved the concept then and still do, but freaked out at the thought of my MAC address being logged everywhere I go.


This is presumably one reason why Apple has stopped broadcasting your real MAC address while doing SSID probes, instead randomizing it.


And Android followed suit. The policy change pretty much bifurcated the industry. Half died or sold themselves off - http://fortune.com/2014/10/29/after-a-blow-from-apple-nomi-s...

The other half doubled down on MAC address tracking tech, arguing that it still generates meaningful data - http://www.euclidanalyticsblog.com/2014/08/beacons-and-wi-fi... Although I've heard they've started to move toward video and facial recog.

We were so small at the time of the announcement last June that we thought... "Why don't we just build a door counter. How fing hard could that be?"

...turns out it's like way, really fing hard.

But here it is - http://i.imgur.com/zLUMAG8.jpg?1


We're happy with the change too. Simplified things. Any sensor trying to mass measure foot traffic across a city needs to be accurate, real time, anonymous, and cheap.


I had a similar idea, I wanted to place small microphones all over the city to know which places were "quieter" than others at certain times of the day etc... I was looking for a place and I wanted to live in a street that was quiet on weeknights


NYC and Chicago both have microphone arrays canvassing the city. There might be a way to get that data

SceneTap is doing something similar with facial recognition technology to layer on age and gender split

The packaging looks really nice. I've always thought other similar services fell short with packaging and presentation.



Thanks kyro. Also, here's the link to whitehouse.gov page: http://www.whitehouse.gov/net-neutrality


I'm 99% sure when I first clicked this link it was the whitehouse.gov one. Why did it get changed to techcrunch?


I took a quick look at the logs and it seems to always have been techcrunch.com until we changed it a minute ago.


The Drapers are quite bullish on Bitcoin. Adam Draper's accelerator, Boost VC, is investing in 100 Bitcoin companies over the next 3 years: http://www.coindesk.com/boost-vc-accelerate-100-bitcoin-comp...


Rob from Gliph here. Gliph is a Bitcoin company from Boost VC Class 2. Tim Draper led our angel round (with Pantera) and is a mentor to Gliph.

Tim has been excited about Bitcoin and its potential for some time. Well in advance of other VCs, Tim was talking about its potential, particularly with regard to "competitive governance."

Have a look at this youtube video from his presentation at Stanford in February of last year: https://www.youtube.com/watch?v=oZ0mrD0EnI0#t=28m05s

He starts describing solutions for competitive governance around 28:05. At 29:10 he brings up Bitcoin. I believe this was the first time he spoke about Bitcoin publicly but may be wrong. He states in the video:

"[bitcoin is] the most valuable currency now on the planet because it is under no one's control. It is out of people's control. It is no longer regulated by any government. They can't print Bitcoin."

Bitcoin was worth about $24.50 when he said that.


The developers and miners are, in effect, the government of bitcoin. The developers act like the federal reserve, in that they can change the code to raise the max amount of bitcoin, increase the mining difficulty, etc. just as the Federal reserve would conduct open market operations or set interest rates to target inflation. So it's completely wrong to say that Bitcoin is "under no one's control". [0]

The key difference is that a majority of the miners have to accept the developer's changes and run the new client. The average US citizen cannot refuse interest rate hikes. So it's a transfer of power away from the few and corrupt (Fed + banks) to the few who are limited in their ability to be corrupt (developers + mining pools).

If the developers implement a terrible policy, the miners will refuse to update their clients to avoid devaluing the currency they are working hard to generate. So the power distribution and incentive structure are different. Whether thats a good or bad thing remains to be seen.

I think a problem in your analysis is that the miners are the equivalent of the Fed, not the developers. The developers are technical experts on whom the miners rely for tools, but are not the equivalent of the substantive decision makers.

But the bigger problem, whether you view miners or miners+developers as parallel to the Fed, is that you've failed present any argument or evidence supporting your key point, to wit, that the "few" who form the "government of bitcoin" (by your description) are somehow inherently "limited in their ability to be corrupt".


The Fed makes the rules. The banks/people perform the actions under those rules that create economic activity in the US.

The Developers make the rules. The miners perform the actions under those rules that create economic activity in the Bitcoin markets.

Say the Fed is corrupt/stupid and enacts a bad policy. The banks/people have no choice but to accept the decision of the Fed. Theoretically you could emigrate, but that is neither desirable nor feasible for the majority of the population.

Say the developers are corrupt/stupid and decide to raise the Bitcoin cap to 30 billion and lower the difficulty, effectively hyperinflating the currency. The mining community has the choice to either a) not accept the changes to the client or b) to vote with their digital feet by moving to another cryptocurrency. They are more likely to choose a) assuming they've been mining for a while/have a reserve of Bitcoin.

The key is that the miners "rely [on the developers] for tools" as you put it. The tools = the client = the rules of the game. So the developers make the rules and the miners decide whether or not to play by them.


They can change the code, but they can't force anyone to adopt the new version. Ultimately, it's the majority of the people running full nodes in the network who are in control, and if they reject a change made by the developers and refuse to upgrade, or even go with a fork, then that's where bitcoin goes.


I'm confused as to why anyone would invest in Bitcoin companies as opposed to Bitcoins directly. The impression I got was that investing in companies provided added risks (co-founder separation, business failure, legal risks), without providing a significant advantage (risk mitigation, upside multiplication) over just buying Bitcoins directly.


The distinction is subtle, but important. Let's say, for example, that I have no real idea what the price of bitcoin should be in five years -- but I am confident that enthusiasm for, and interest in, bitcoin buying and trading will grow dramatically all the while. I'd rather own the company processing the transactions than the bitcoin itself. The bitcoin might soar, and it might tank, and it might do both of those things in a mostly unpredictable, haphazard fashion. (As has been happening.) But the companies trading bitcoin don't necessarily need to buy and hold. They can make money off of transaction volume, or off of leverage against their bitcoin assets, or off of any number of things only tangentially affected by the nominal value of bitcoin.

This is sort of like the old saying about how to make money in a gold rush. You don't mine for gold; you sell picks and shovels.


There are scenarios in which the Bitcoin "sector" grows without the value of Bitcoins themselves appreciating significantly (or at least, to the same extent). For example it could become a common medium of exchange but an uncommon medium to hold, if a large portion of the growth is in Bitcoin exchange platforms that convert payments immediately to national currencies, like BitPay. In such a situation there could be a large volume of business going through companies like BitPay, but with only transient demand for the coins themselves.


Without the infrastructure to support bitcoins, the value bitcoins will remain stagnate or may even go down. Investing in companies to build out infrastructure for this currency is only "sure" bet you can take unless you gamble on someone else to make the investment.


Bitcoin companies may quickly move to focus on properties of the blockchain that are not related (and, perhaps more importantly, more profitable), than the bitcoin currency.

Also, importantly, bitcoins may be extraordinarily profitable for a bitcoin company, but never increase in value, whereas if you purchased a bitcoin today for $700, and 5 years from now, the bitcoin was still $700, you would likely be unhappy.


> Bitcoin companies may quickly move to focus on properties of the blockchain that are not related (and, perhaps more importantly, more profitable)

What properties?


The consensus based global ledger of script based transactions. Bitcoin currency is just one application of such a system. Others, such as Contracts, Escrow, Title Assignment have been proposed as well - and the transaction fees of such might be much more profitable than simply identifying a input/output of a bitcoin transaction.


Cashflow. The company can sell a service and have perpetual income. If bitcoin losses value, you are still generating income, as opposed to having your money invested directly in the currency.


So I need an RPi (finally, a reason to use mine...) and a supported video camera? What other devices are you adding and when? Any other examples other than this: http://crowsnestdemo.tumblr.com.

Really cool idea, good luck with it.


We started out with cameras because they are pretty rich devices, and we wanted to start with just one device. We are currently working on an open source plugin system with the intention that anyone will be able to add IP devices to Crowsnest. We're aiming to have this out in about a month.

When we release the plugin system, we're also going to release a handful of integrations made using it, including things like the Wemo outlets / switches, Philips Hue, Nest Thermostat, and Libelium's air quality / water quality / smart agriculture sensors. We want to build things that the community and our customers need, so if there are things that would be particularly useful or interesting, we'd love to work on those first. We're always looking for feedback and ideas.
