RapidDeploy raises $29M for a cloud-based dispatch platform aimed at 911 centers

Avatar

The last year of pandemic living has been real-world, and sometimes harrowing, proof of how important it can be to have efficient and well-equipped emergency response services in place. They can help people remotely if need be, and when they cannot, they make sure that in-person help can be dispatched quickly in medical and other situations. Today, a company that’s building cloud-based tools to help with this process is announcing a round of funding as it continues to grow.

RapidDeploy, which provides computer-aided dispatch technology as a cloud-based service for 911 centers, has closed a round of $29 million, a Series B round of funding that will be used both to grow its business, and to continue expanding the SaaS tools that it provides to its customers. In the startup’s point of view, the cloud is essential to running emergency response in the most efficient manner.

“911 response would have been called out on a walkie talkie in the early days,” said Steve Raucher, the co-founder and CEO of RapidDeploy, in an interview. “Now the cloud has become the nexus of signals.”

Washington, DC-based RapidDeploy provides data and analytics to 911 centers — the critical link between people calling for help and connecting those calls with the nearest medical, police or fire assistance — and today it has about 700 customers using its RadiusPlus, Eclipse Analytics and Nimbus CAD products.

That works out to about 10% of all 911 centers in the US (7,000 in total), and covering 35% of the population (there are more centers in cities and other dense areas). Its footprint includes state coverage in Arizona, California, and Kansas. It also has operations in South Africa, where it was originally founded.

The funding is coming from an interesting mix of financial and strategic investors. Led by Morpheus Ventures, the round also had participation from GreatPoint Ventures, Ericsson Ventures, Samsung Next Ventures, Tao Capital Partners, Tau Ventures, among others. It looks like the company had raised about $30 million before this latest round, according to PitchBook data. Valuation is not being disclosed.

Ericsson and Samsung, as major players in the communication industry, have a big stake in seeing through what will be the next generation of communications technology and how it is used for critical services. (And indeed, one of the big leaders in legacy and current 911 communications is Motorola, a would-be competitor of both.) AT&T is also a strategic go-to-market (distribution and sales) partner of RapidDeploy’s, and it also has integrations with Apple, Google, Microsoft, and OnStar to feed data into its system.

The business of emergency response technology is a fragmented market. Raucher describes them as “mom-and-pop” businesses, with some 80% of them occupying four seats or less (a testament to the fact that a lot of the US is actually significantly less urban than its outsized cities might have you think it is), and in many cases a lot of these are operating on legacy equipment.

However, in the US in the last several years — buffered by innovations like the Jedi project and FirstNet, a next-generation public safety network — things have been shifting. RapidDeploy’s technology sits alongside (and in some areas competes with) companies like Carbyne and RapidSOS, which have been tapping into the innovations of cell phone technology both to help pinpoint people and improve how to help them.

RapidDeploy’s tech is based around its RadiusPlus mapping platform, which uses data from smart phones, vehicles, home security systems and other connected devices and channels it to its data stream, which can help a center determine not just location but potentially other aspects of the condition of the caller. Its Eclipse Analytics services, meanwhile, are meant to act as a kind of assistant to those centers to help triage situations and provide insights into how to respond. The Nimbus CAD then helps figure out who to call out and routing for response. 

Longer term, the plan will be to leverage cloud architecture to bring in new data sources and ways of communicating between callers, centers and emergency care providers.

“It’s about being more of a triage service rather than a message switch,” Raucher said. “As we see it, the platform will evolve with customers’ needs. Tactical mapping ultimately is not big enough to cover this. We’re thinking about unified communications.” Indeed, that is the direction that many of these services seem to be going, which can only be a good thing for us consumers.

“The future of emergency services is in data, which creates a faster, more responsive 9-1-1 center,” said Mark Dyne, Founding Partner at Morpheus Ventures, in a statement. “We believe that the platform RapidDeploy has built provides the necessary breadth of capabilities that make the dream of Next-Gen 9-1-1 service a reality for rural and metropolitan communities across the nation and are excited to be investing in this future with Steve and his team.” Dyne has joined the RapidDeploy board with this round.

DataRobot expands platform and announces Zepl acquisition

Avatar

Published

DataRobot, the Boston-based automated machine learning startup, had a bushel of announcements this morning as it expanded its platform to give technical and non-technical users alike something new. It also announced it has acquired Zepl, giving it an advanced development environment where data scientists can bring their own code to DataRobot. The two companies did not share the acquisition price.

Nenshad Bardoliwalla, SVP of Product at DataRobot says that his company aspires to be the leader in this market and it believes the path to doing that is appealing to a broad spectrum of user requirements from those who have little data science understanding to those who can do their own machine learning coding in Python and R.

“While people love automation, they also want it to be [flexible]. They don’t want just automation, but then you can’t do anything with it. They also want the ability to turn the knobs and pull the levers,” Bardoliwalla explained.

To resolve that problem, rather than building a coding environment from scratch, it chose to buy Zepl and incorporate its coding notebook into the platform in a new tool called Composable ML. “With Composable ML and with the Zepl acquisition, we are now providing a really first class environment for people who want to code,” he said.

Zepl was founded in 2016 and raised $13 million along the way, according to Crunchbase data. The company didn’t want to reveal the number of employees or the purchase price, but the acquisition gives it advanced capabilities, especially a notebook environment to call its own to attract those more advanced users to the platform.The company plans to incorporate the Zepl functionality into the platform, while also leaving the stand-alone product in place.

Bardoliwalla said that they see the Zepl acquisition as an extension of the automated side of the house, where these tools can work in conjunction with one another with machines and humans working together to generate the best models. “This [generates an] organic mixture of the best of what a system can generate using DataRobot AutoML and the best of what human beings can do and kind of trying to compose those together into something really interesting […],” Bardoliwalla said.

The company is also introducing a no-code AI app builder that enables non-technical users to create apps from the data set with drag and drop components. In addition, it’s adding a tool to monitor the accuracy of the model over time. Sometimes, after a model is in production for a time, the accuracy can begin to break down as the data the model is based is no longer valid. This tool monitors the model data for accuracy and warns the team when it’s starting to fall out of compliance.

Finally the company is announcing a model bias monitoring tool to help root out model bias that could introduce racist, sexist or other assumptions into the model. To avoid this, the company has built a tool to identify when it sees this happening both in the model building phase and in production. It warns the team of potential bias, while providing them with suggestions to tweak the model to remove it.

DataRobot is based in Boston and was founded in 2012. It has raised over $750 million and has a valuation of over $2.8 billion, according to Pitchbook.

Powering the Next Wave of Healthcare Innovation with AI

AI Healthcare

There’s no doubt that data is poised to transform healthcare like it has so many other sectors, but it’ll need a helping hand. Today, healthcare providers collect exabytes of patient data from hospitals, clinics, imaging and pathology labs, and more. This data contains a wealth of insight into human health, but its lack of structure and sheer volume means it’s well beyond the limits of human ability to decipher it.

Fortunately, sophisticated AI and machine learning solutions can carry the torch of innovation.

In healthcare, the value of machine learning is its capacity for processing massive data sets that are far beyond the scope of human ability. Raw, unstructured data goes in, and clinical insights come out, helping physicians plan and provide better care at a lower cost. While the sky is the limit as far as the benefits of machine learning, constructing these complex algorithms takes time. In the next five to 10 years, we expect to see medical professionals reaping the dividends of healthcare-based innovation in these areas:

Advanced Image Analysis

Medical professionals are highly trained, and some of their work reflects their tremendous value add. However, there’s still a need for professionals to spend time on repetitive tasks such as image analysis. In radiology, for example, doctors spend time looking at images from CT scans, MRIs, ultrasounds, PET scans, mammography, and more. AI-assisted imaging solutions use the technology’s advanced pattern-recognition capabilities to highlight image features, identify early predictors of cancer, prioritize cases, and cut down on the volume of labor required to perform accurate diagnoses. As AI processes more and more data sets, the technology will inevitably eclipse the ability of human doctors to spot the signs of disease as early as possible.

Disease Detection

Due to its high cost, healthcare imaging generally takes place only to confirm a diagnosis. It’s an effective solution, but one that AI promises to upend and replace. By conducting an in-depth analysis of huge amounts of historical data, AI can predict the possibility of sickness or disease at incredibly early stages. For example, by looking at an entire patient population that closely matches the demographic of a specific individual in addition to the medical history of relatives, AI could conclude that a patient is very likely to develop a malady such as heart disease years before a doctor could ever accurately make a diagnosis.

Drug Discovery

We’ve all seen firsthand how important it is to design and produce effective drugs and vaccines to combat a newly discovered disease. Historically, this process has taken massive investments of time and money, with development timelines extending out to more than a decade in some cases. The ability of AI to cross-reference drugs that are known to be safe and effective and replicate parts of their formulas to suggest new iterations could be groundbreaking, potentially saving countless lives and helping to prevent the next global pandemic.

Digital Consultation

The pandemic undoubtedly spurred innovation in the telehealth space. However, there’s still a long way to go to make virtual visits as effective as a physical visit to the doctor’s office. AI can help close that gap in numerous ways. Machine learning and natural language processing (NLP), for example, will help facilitate symptom collection using just a patient’s voice. Combined with an analysis of the patient’s electronic health record, AI can highlight probable health concerns for doctors to review. By processing information ahead of time, AI increases the volume of patients that doctors can handle, improves the efficacy of virtual visits, and even minimizes the risk of infection from physical interactions as a result.

CMU researchers show potential of privacy-preserving activity tracking using radar

Avatar

Published

on

Imagine if you could settle/rekindle domestic arguments by asking your smart speaker when the room last got cleaned or whether the bins already got taken out?

Or — for an altogether healthier use-case — what if you could ask your speaker to keep count of reps as you do squats and bench presses? Or switch into full-on ‘personal trainer’ mode — barking orders to peddle faster as you spin cycles on a dusty old exercise bike (who needs a Peloton!).

And what if the speaker was smart enough to just know you’re eating dinner and took care of slipping on a little mood music?

Now imagine if all those activity tracking smarts were on tap without any connected cameras being plugged inside your home.

Another bit of fascinating research from researchers at Carnegie Mellon University’s Future Interfaces Group opens up these sorts of possibilities — demonstrating a novel approach to activity tracking that does not rely on cameras as the sensing tool. 

Installing connected cameras inside your home is of course a horrible privacy risk. Which is why the CMU researchers set about investigating the potential of using millimeter wave (mmWave) doppler radar as a medium for detecting different types of human activity.

The challenge they needed to overcome is that while mmWave offers a “signal richness approaching that of microphones and cameras”, as they put it, data-sets to train AI models to recognize different human activities as RF noise are not readily available (as visual data for training other types of AI models is).

Not to be deterred, they set about sythensizing doppler data to feed a human activity tracking model — devising a software pipeline for training privacy-preserving activity tracking AI models. 

The results can be seen in this video — where the model is shown correctly identifying a number of different activities, including cycling, clapping, waving and squats. Purely from its ability to interpret the mmWave signal the movements generate — and purely having been trained on public video data. 

“We show how this cross-domain translation can be successful through a series of experimental results,” they write. “Overall, we believe our approach is an important stepping stone towards significantly reducing the burden of training such as human sensing systems, and could help bootstrap uses in human-computer interaction.”

Researcher Chris Harrison confirms the mmWave doppler radar-based sensing doesn’t work for “very subtle stuff” (like spotting different facial expressions). But he says it’s sensitive enough to detect less vigorous activity — like eating or reading a book.

The motion detection ability of doppler radar is also limited by a need for line-of-sight between the subject and the sensing hardware. (Aka: “It can’t reach around corners yet.” Which, for those concerned about future robots’ powers of human detection, will surely sound slightly reassuring.)

Detection does require special sensing hardware, of course. But things are already moving on that front: Google has been dipping its toe in already, via project Soli — adding a radar sensor to the Pixel 4, for example.

Google’s Nest Hub also integrates the same radar sense to track sleep quality.

“One of the reasons we haven’t seen more adoption of radar sensors in phones is a lack of compelling use cases (sort of a chicken and egg problem),” Harris tells TechCrunch. “Our research into radar-based activity detection helps to open more applications (e.g., smarter Siris, who know when you are eating, or making dinner, or cleaning, or working out, etc.).”

Asked whether he sees greater potential in mobile or fixed applications, Harris reckons there are interesting use-cases for both.

“I see use cases in both mobile and non mobile,” he says. “Returning to the Nest Hub… the sensor is already in the room, so why not use that to bootstrap more advanced functionality in a Google smart speaker (like rep counting your exercises).

“There are a bunch of radar sensors already used in building to detect occupancy (but now they can detect the last time the room was cleaned, for example).”

“Overall, the cost of these sensors is going to drop to a few dollars very soon (some on eBay are already around $1), so you can include them in everything,” he adds. “And as Google is showing with a product that goes in your bedroom, the threat of a ‘surveillance society’ is much less worry-some than with camera sensors.”

Startups like VergeSense are already using sensor hardware and computer vision technology to power real-time analytics of indoor space and activity for the b2b market (such as measuring office occupancy).

But even with local processing of low-resolution image data, there could still be a perception of privacy risk around the use of vision sensors — certainly in consumer environments.

Radar offers an alternative to such visual surveillance that could be a better fit for privacy-risking consumer connected devices such as ‘smart mirrors‘.

“If it is processed locally, would you put a camera in your bedroom? Bathroom? Maybe I’m prudish but I wouldn’t personally,” says Harris.

He also points to earlier research which he says underlines the value of incorporating more types of sensing hardware: “The more sensors, the longer tail of interesting applications you can support. Cameras can’t capture everything, nor do they work in the dark.”

“Cameras are pretty cheap these days, so hard to compete there, even if radar is a bit cheaper. I do believe the strongest advantage is privacy preservation,” he adds.

Of course having any sensing hardware — visual or otherwise — raises potential privacy issues.

A sensor that tells you when a child’s bedroom is occupied may be good or bad depending on who has access to the data, for example. And all sorts of human activity can generate sensitive information, depending on what’s going on. (I mean, do you really want your smart speaker to know when you’re having sex?)

So while radar-based tracking may be less invasive than some other types of sensors it doesn’t mean there are no potential privacy concerns at all.

As ever, it depends on where and how the sensing hardware is being used. Albeit, it’s hard to argue that the data radar generates is likely to be less sensitive than equivalent visual data were it to be exposed via a breach.

“Any sensor should naturally raise the question of privacy — it is a spectrum rather than a yes/no question,” agrees Harris.  “Radar sensors happen to be usually rich in detail, but highly anonymizing, unlike cameras. If your doppler radar data leaked online, it’d be hard to be embarrassed about it. No one would recognize you. If cameras from inside your house leaked online, well… ”

What about the compute costs of synthesizing the training data, given the lack of immediately available doppler signal data?

“It isn’t turnkey, but there are many large video corpuses to pull from (including things like Youtube-8M),” he says. “It is orders of magnitude faster to download video data and create synthetic radar data than having to recruit people to come into your lab to capture motion data.

“One is inherently 1 hour spent for 1 hour of quality data. Whereas you can download hundreds of hours of footage pretty easily from many excellently curated video databases these days. For every hour of video, it takes us about 2 hours to process, but that is just on one desktop machine we have here in the lab. The key is that you can parallelize this, using Amazon AWS or equivalent, and process 100 videos at once, so the throughput can be extremely high.”

And while RF signal does reflect, and do so to different degrees off of different surfaces (aka “multi-path interference”), Harris says the signal reflected by the user “is by far the dominant signal”. Which means they didn’t need to model other reflections in order to get their demo model working. (Though he notes that could be done to further hone capabilities “by extracting big surfaces like walls/ceiling/floor/furniture with computer vision and adding that into the synthesis stage”.)

“The [doppler] signal is actually very high level and abstract, and so it’s not particularly hard to process in real time (much less ‘pixels’ than a camera).” he adds. “Embedded processors in cars use radar data for things like collision breaking and blind spot monitoring, and those are low end CPUs (no deep learning or anything).”

The research is being presented at the ACM CHI conference, alongside another Group project — called Pose-on-the-Go — which uses smartphone sensors to approximate the user’s full-body pose without the need for wearable sensors.

CMU researchers from the Group have also previously demonstrated a method for indoor ‘smart home’ sensing on the cheap (also without the need for cameras), as well as — last year — showing how smartphone cameras could be used to give an on-device AI assistant more contextual savvy.

In recent years they’ve also investigated using laser vibrometry and electromagnetic noise to give smart devices better environmental awareness and contextual functionality. Other interesting research out of the Group includes using conductive spray paint to turn anything into a touchscreen. And various methods to extend the interactive potential of wearables — such as by using lasers to project virtual buttons onto the arm of a device user or incorporating another wearable (a ring) into the mix.

The future of human computer interaction looks certain to be a lot more contextually savvy — even if current-gen ‘smart’ devices can still stumble on the basics and seem more than a little dumb.
