We get it: there’s a silly number of mobile messaging apps out there, and a great many of them are meant for you to share your banalities more easily. But a Philadelphia-based startup called Seratis is different.

Before Divya Dhar founded Seratis earlier this year, she was a practicing physician who had to use a work-issued pager to try to keep tabs on her patients and colleagues. That didn’t stop her fellow doctors from using smartphones to do the same thing – it’s the 21st century for heaven’s sake – but it turns out sharing that kind of information over insecure protocols isn’t exactly lawful.

Enter Seratis, a secure, HIPAA-compliant messaging app that may finally kill medical pagers dead.

Frankly, it’s sort of a surprise to hear that pagers are still widely used since they’ve all but disappeared from the public vernacular, but Dhar told me at Dreamit Ventures’ Philadelphia Health Demo Day that “90 percent of hospital communications still flows through pagers.” Turns out they’re pretty expensive, too.

“Everyone knows pagers need to go, and everyone is moving towards that,” she added.

Here’s how Seratis works: you log into the service as you would any other mobile messaging app, but the app organizes messages based on the patient they pertain to, so the entire team can see exactly what’s been going on with a particular person before they even check in for their shift. Even better, the app gives physicians direct access to colleagues they may rarely see, which makes for a much more fluid transfer of patient information.

After all, if you need clarification about a patient’s condition from a fellow doctor you haven’t run into before, imagine how long it would take to track down their contact info, reach out to them (assuming they’re not knee-deep in other work), and respond accordingly? That’s time that could be much better spent, and Dhar is frankly pretty sick of wasting it. Throw in support for read receipts and a quick, at-a-glance view of a patient’s entire medical team, and you’ve got a solid little smartphone app.

Turns out, the app is only part of the solution (data nerds may like where this is going). Hospitals and wards inside them will have access to important analytics from those conversations – some of the metrics like messaging volume and response time are pretty straightforward, but Seratis can also track specific words as they’re thrown around. Think of it as a lexicological early-warning system. If a slew of doctors working with multiple patients all repeatedly use the word “infection” on the same floor, something bad may be brewing. Seratis will be able to flag this so staffers and administrators can prepare and respond accordingly.

Of course, Seratis’ model isn’t exactly without its drawbacks. If you’re going to implement a crucial smartphone-centric messaging system in a hospital, you need to make sure every doctor who needs to use it actually has a smartphone. Considering smartphone penetration rates, there’s a solid chance that most physicians already have one, but Dhar conceded that some hospitals may need to offer incentives like data plan reimbursement to coax doctors into joining the BYOD bandwagon.

The team is also still trying to figure out the sweet spot, but Seratis plans to charge users per month so it can fit into small hospitals, as well as sprawling ones. Right now an alpha version of the iOS app (an Android version is in the pipeline, too) is being tested by Penn Medicine, but here’s hoping my doctors can more easily communicate about all my terrible miscellaneous ailments sooner rather than later.

A new Kickstarter project wants to let a little light shine in on your mobile photos – much more than the built-in flash on devices like the iPhone 5 can provide alone. The iblazr is an external flash that uses four high-output CREE LED lights to provide a whole lot of illumination via a small piece of hardware that plugs into your gadget’s headphone jack, easily outgunning the iPhone’s flash, and giving the flash-less iPad something to shine on photographic subjects.

The iblazr is entirely synchronized with your device’s camera shutter, too, thanks to a proprietary free app for iOS and Android. It has a number of different features, including photo and video modes, a constant light mode, changeable brightness, and a built-in, USB rechargeable battery that lasts up to 1,000 flashes. The iblazr recharges via a flexible USB cable, and it even works without a smartphone or connected device at all, providing you a tiny pocket flashlight as well.

If you’re serious about your Instagrams, or about not carrying a dedicated camera around and still getting good shots, the iblazr looks to be a smart option, as it offers less chance to result in red-eye than the built-in flash, more than doubles the brightness possible and can even act as a fill flash for daylight outdoor shots to prevent exposure from becoming unbalanced between light and dark background and foreground.

The iblazr includes its own free app, but its creators also made it open source, and are offering SDK access before its general release to backers. Already a number of apps are signed up on both Android and iOS to take advantage of the accessory, so it’s possible your favourite mobile photography app will be able to take advantage, too.

iblazr is the product of a team based in Kiev, Ukraine, which includes a number of designers and engineers who have worked on hardware and software projects related to camera and photography gear before. Two of the team members were the first to solve flash synchronization issues with external devices on the iPhone, making the iblazr’s tricks possible.

The startup is looking for $58,000 in funding, and has raised nearly half so far. $39 is the price of admission for a pre-order pledge, which gets you one white or black iblazr with charger, with an expected ship date of December, 2013.

Strap on a tin foil hat and dust off your VHS tape of Hackers because a thrilling, civilized discussion of contemporary cybersecurity is coming to TechCrunch Disrupt SF. I’ll be joined onstage by some of the leading security experts to discuss cyber threats from hostile foreign governments, rogue hacker groups, corporate espionage, and complications of the surveillance state.

Heather Adkins was head of cybersecurity at Google at just 25 years old and is now a veteran in securing one of the most sought-after Internet companies in the world.

Kevin Mandia, CEO of Mandiant, made front-page headlines around the world after unmasking China’s infamous cyber army. Within the industry, it’s known that if you have to call Mandia, you have serious problems from the toughest cyber criminals on the net.

Ted Schlein of Kleiner Perkins Caufield & Byers knows as much about the business of cyber security -both defense and offense – as anyone in Silicon Valley. Governments have big money to throw at cyber defense and it’s Schlein’s job to identify the most profitable private partners.

When the National Security Agency made headlines this summer, media outlets turned to arguably the most knowledgeable journalist on the secret spy organization, James Bamford.

Now, imagine all the contentious ethical quandaries and business pressures that come from cybersecurity. We’ll be discussing all of these, sometimes with fierce disagreement, with people who have staked their reputations on being right. This panel kicks off at 11:30 on Tuesday, September 10.

General-admission tickets and exhibitor packages are currently available. Buy tickets here.

For whatever reason, this week has felt particularly long. It might be some astrological reason like Mercury in retrograde. Or it might just be the emotions that are a package deal with being a woman at the end of any month.

Or it might be that burrito haven Chipotle fake-hacked its Twitter account on Sunday, and the stunt has left a bad taste in my mouth.

Brands who stage fake hackings as an attempt to #winthemoment, does the world really need more Internet mistrust post-NSA PRISM?

Is fake hacking really something you’d like to have forever associated with your brand? Do you really want Pete Cashmore sopping up pageviews debunking your lame attempt at garnering publicity?

For that matter, is using twelve people to “position” a tweet really the best use of your precious time left on the planet? I mean, doing anything on Twitter nowadays is lauded as being cool and fresh. Even if the content itself is not cool and fresh. We’re on to you, Oreo.

The only reason I’m bringing this up is because the world is in the middle of an economic Cold War: On one side, over a billion people who make less than $1.25 per day; on the other, a class of overprivileged digital natives like myself who get paid to spend their lives on Twitter, Facebook and Instagram, thinking up new ways to “go viral.””What if we faked a hack …?!”

The only way this will end is with my head on a spike. Let them snap chats!

Hit send too soon!-

AngelList is testing out a new service that lets angel investors syndicate deals with each other, a feature that could allow startups to raise venture-sized rounds of money with relative ease. Called Syndicates, the private-beta product lets any accredited investor on the AngelList fundraising platform essentially create, lead and collect carry for a fund of angel money for a specific startup.

The carry part could help motivate an angel who truly believes in the startup to put in the hard work of helping it raise all the money it thinks it needs. In a world where more startups than ever are trying to raise money, and more investors are competing to find the best ones, this model may quickly become popular.

Here’s a bit more about how it works, as gleaned from the newly-public FAQ from AngelList, the resulting conversation around the news on Twitter, and a conversation with AngelList cofounder Naval Ravikant. The news, we’ll note, was broken by anonymous startup personality Startup L. Jackson… who presumably has investor-level access to AngelList, whoever he or she is.

VCs and their limited partners (the entities who put money into VC funds) already use carry to align their interests. In addition to the VC partners collecting a set management fee for each fund, the carry provides them with a percentage of the profit for the fund.

In the AngelList implementation of the concept, the lead angel picks the percentage carry that they’ll get from a positive return in the company if it has a liquidity event. They can set this to zero, which would make the most sense if they’re relatively unknown and most concerned with building a reputation. Or they can set any amount above that – 40% could make sense, for example, if you’re a top angel and looking to monetize your reputation and deal flow.

The FAQ provides the following example of how a lead angel would use Syndicates:

Sara decides to invest in a startup and asks for a $250k allocation in the company. She personally takes $50K of the allocation and decides to syndicate the rest. She shares the deal with investors and specifies that she is charging a 20% carry on the remaining $200k of her allocation. Sara’s capital and her co-investor’s capital is pooled into a $250K fund which invests in the startup.

Sara’s co-investors pay carry for her access, governance and value-add. She sourced the deal and used her judgment to select the investment. She manages the fund and provides oversight for her co-investors’ capital. And she provides ongoing value-add to the startup.

AngelList takes 5% regardless, which makes Syndicates a potentially big revenue stream for the funding platform. It also sets each Syndicate up as an LLC specifically for the startup in question, with the lead angel signing off as an investment advisor. This legally obligates the angel to disclose any conflicts, such as other strategic or financial relationships with the startup.

As part of the service, AngelList also requires the lead to put up at least 10% of their own money into this vehicle, in contrast with the much lower percentages that LPs typically require of VC funds. In my discussion with Ravikant, he adds a few other points on how he sees Syndicates working.

“The backers are likely to be LPs, family offices [of the very wealthy], passive angels, and angels out of market who can’t get into a deal or don’t want to spend the time,” he explains. Meanwhile, the lead angel is expected to take this more seriously than some angels might be used to, in that they are expected to “provide access, oversight, and help the company.”

At the same time, he disputes the notion that Syndicates is competing against VCs here – an assumption one might make given that Syndicates could help a company raise a lot of money quickly. “This isn’t about ‘without VCs’ – in our test, anyone investing less than $100K per deal goes via Syndicates. Over that and you get a direct intro. If you’re putting in serious money, the company wants to meet you. The two will coexist.”

“In fact,” he adds, “some well known VCs have already approached us about syndicating deals – they wouldn’t take a carry, but would get advisory shares for being on the board and / or get to control syndicate allocations and voting. We are also talking to seed funds who want extra leverage.”

A less obvious benefit of the setup is that angels now have a new way to take advantage of pro rata terms. Typical deal terms already allow investors to continue putting money into a company in order to maintain their existing percentage, even as the company raises new funding at higher valuations. But, many angels do not want to raise or borrow the money to do this, so they forego the option. With Syndicates, the investor can fundraise to buy stock made available via pro rata terms, and collect carry on any resulting profit.

What about the murky world of finance law? Where does the Securities and Exchange Commission stand on this new method of raising money? AngelList has obtained a no-action letter from the federal agency, which means that it can launch the service without fear of its legal reprisal. You can view the PDF here.

But wait, how new is this concept? Finance writer Dan Primack notes that “fundless sponsors” already exist, and indeed they’ve become an increasingly common method for private equity investors to pool money in recent years.

There are very few instances of a carry-based LLC being used for angel investment, though. FundersClub, a relatively new investment-vehicle startup focused on raising funds around startups and startup categories, has also been pursuing it. Sequoia’s long-running “Scout” program is another, albeit at an intentionally smaller scale. To Ravikant, “[t]his is closer to Sequoia scouts than anything else. It allows anyone to be a scout, not just Sequoia’s CEOs, and anyone to be a backer, not just Sequoia. And it’s all carry-based (no fees).”

He adds that this is just a test for the next couple months. It may not work, or the implementation may change.

But any startup that needs funding and has an angel lined up is going to be looking at Syndicates hard as a new option. And the early-stage investment community is already busy trying to figure out the threats and opportunities.

Finally, the SEC, Congress and other government entities are currently changing the rules for private fundraising, which could make Syndicates explode in popularity. Private companies could soon be able to publicly advertise that they’re looking for money, which might help them benefit from the Syndicates concept immediately. And if non-accredited investors are allowed in, lots more money could start to flow through, too (and Startup L. Jackson will have a tougher time beating the tech press on AngelList scoops).

[Disclosure: AngelList has a partnership with our CrunchBase startup database product, a non-exclusive deal that is unrelated to this news as far as I know. I also have no financial relationship with AngelList, except through my nearly worthless employee stock option plan with Aol, the owner of TechCrunch and CrunchBase.]

“Any sufficiently advanced technology is indistinguishable from magic.”

-Sir Arthur C. Clarke

It’s probably the most overused quote in tech writing… which sucks, because I’d really like to use it to describe how I feel about the Chromecast.

The Chromecast is deceptively simple: you plug it into your TV, then stream video and music to it from apps running on your iPhone, Android device, or laptop. The Chromecast itself has no remote; whatever device you’re streaming from is the remote. The Chromecast has next to no user interface of its own, either; it’s got a single screen that shows the time and whether or not it’s connected to your WiFi that appears when nothing is being streamed, but again, the device you’re streaming from largely acts as the interface. The Chromecast is a wireless portal to your TV, and doesn’t try to be anything more.

A Box Full Of Surprises

I’ve been thinking about it all night, and I don’t think I’ve ever been as surprised by a device as I am by the Chromecast.

The price? Surprise! It’s $35. Are you kidding me? According to Google, they’re not selling them at a loss. Even after accounting for the Wi-Fi chip, the CPU, 2GB of flash memory, the RAM, licensing the right to use HDMI, assembly, packaging, and shipping them to the states, they’re somehow making money selling these things for thirty five dollars. Sure, their profit margin is probably like, four cents – but that they’re not selling these at a loss at that price point is kind of absurd.

The setup? Surprise! It’s ridiculously easy. Plug it into HDMI, give it some juice (through USB, which most new TVs have, or a standard wallwart), then run the Chromecast app on a laptop to tell it what Wi-Fi network to connect to. Done.

App compatibility? Surprise! It’s already there on day one in some of the most notable online video apps, including Netflix and YouTube. I didn’t even have to update the apps – I just launched ’em on my phone and the Chromecast button was sitting there waiting for me. They’ve even already built an extension for Chrome that drastically expands the functionality of the device (though, in its beta state, it’s a bit buggy – more on that later).

Hell, even the very announcement of the Chromecast was a bit of a surprise. Google somehow managed to keep the Chromecast a secret until right before its intended debut, even with a bunch of outside parties involved. Netflix, Pandora, teams from all over Google, everyone involved in the manufacturing process – all of them were in the loop, yet nothing leaked until someone accidentally published a support page a few hours too early.

Now, none of that is to suggest that the Chromecast is perfect. It’s not! Not yet, at least. But its biggest issues are quite fixable, assuming that Google doesn’t look at the “overwhelming” sales of the Chromecast and say ‘Oh, well, screw this thing.’ And for just $35, the few blemishes it has are pretty easy to overlook.

Taking The Bad With The Good:

Video streaming quality is quite good (on par with what I get on my Xbox 360 or my Apple TV, at least) particularly when pulling from an app or website that’s been tailored for compatibility – so Netflix, Youtube, or Google Play, at the moment.

If you’re using the Chromecast extension for Chrome on your laptop to project an otherwise incompatible video site (like Hulu or HBOGO), however, video quality can dump quite a bit depending on your setup. It’s using your laptop as a middle man to encode the video signal and broadcast it to the Chromecast, whereas the aforementioned compatible sites just send video straight to the dongle, mostly removing your laptop from the mix. When casting video tabs on a 2012 MacBook Air running on an 802.11n network, the framerate was noticeably lower and there were occasional audio syncing issues.

While we’re on the topic, the Chrome extension packs a bit of an easter egg: the ability to stream local videos from your laptop to the Chromecast. Just drag a video into Chrome, and it’ll start playing in a new tab. Use the Chrome extension to cast that tab, and ta da! You’re streaming your (totally legitimate, not-at-all-pirated-am-i-right) videos without bringing any other software into the mix. I tried it with a bunch of video formats (mostly AVIs and MKVs. MOVs kinda-sorta work, though most won’t push audio from the laptop to the TV for some reason), and they all seemed to work quite well, albeit with the lowered framerate I mentioned earlier.

Even within the apps that have already been tweaked for Chromecast compatibility, there are some day one bugs. Sometimes videos don’t play the first time you ask them to, instead dropping you into a never-ending loading screen. Other times, the video’s audio will start playing on top of a black screen. These bugs aren’t painfully common, but they’re not rare, either.

Fortunately, it’s mostly all good – and it can only get better

Even with a bug or two rearing its head, the Chromecast is easily worth its $35 price tag.

Remember, this thing just launched, and it came mostly out of nowhere. Those bugs? They’ll get patched away. The sometimes-iffy framerate on projected tabs? It’ll almost certainly get better, as the Chromecast extension comes out of beta.

Pitted against the AppleTV – or, in a fairer comparison, against the AppleTV’s built-in AirPlay streaming feature – the Chromecast’s biggest strength is in its cross-platform compatibility. Whereas AirPlay is limited to iOS devices and Macs (with limited support for Windows through iTunes), Chromecast will play friendly with any iOS, Android, Mac, or Windows app that integrates Googles Cast SDK. Having just launched, the Cast protocol obviously isn’t nearly as ubiquitous as AirPlay, either in terms of Apps that support it or in terms of other devices (like wireless speakers) that utilize it – but assuming that developers embrace the format (and really, they should), both of those things could quickly change. If developers support the protocol, Google could quite feasibly open it up to third parties to be integrated directly into TVs, speakers, and other types of gadgets. If that happens, AirPlay could be in trouble.

On the topic of its cross-platform compatibility: the experience on Android is a slightly better than it is on iOS, as Google has considerably more freedom on the platform; for example, apps that use Chromecast can take priority over the lockscreen, allowing the user to play/pause/skip a video without having to fully unlock their Android device. That’s just icing on the cake, though; for the most part, all of the primary features work just as well on iOS as they do on Android.


It’s one of the easiest recommendations I’ve ever made: If the Chromecast sounds like something you’d want, buy it. It’s easily worth $35 as it stands, and it’s bound to only get better as time goes on, the bugs get ironed out, and more apps come to support it.

[Disclosure: Google loaned me this Chomecast for me to tinker with, but it goes back as soon as my review is done. With that said, I liked it enough that I’ve already ordered one of my own.]
