Houston hospital introduces first-of-its-kind voice technology into its operating rooms

Hey, MIA

Hey, MIA. Start surgery.

These are the words Houston doctors are learning to say in the operating rooms, thanks to a first-of-its-kind voice technology developed by the Houston Methodist's Center for Innovation in collaboration with Amazon Web Services. In the same way we use programs like Alexa or Siri to make our everyday tasks easier, the Methodist Intelligent Automation, or MIA, is allowing medical professionals to improve the way they interact both with technology and patients alike.

"There's been a push in the industry for a long time that people sitting behind computers and typing and staring at a computer screen is inadequate," says Houston Methodist Chief Innovation Officer Roberta Schwartz. "There's been a desire to return people back to each other rather than physicians and look at a screen and patients look at a doctor looking at a screen."

Currently in its pilot phase, MIA is working to do just that through two key functions that shift the way medical professionals work in what Schwartz calls the "era of electronic medical records."

The first is through operating room voice commands. Here medical professionals can run through a series or checklists and initiate important actions, such as starting timers or reviewing time of anesthesia, through voice instead of by typing or clicking, which can become cumbersome during lengthy and highly detailed surgeries. Information is displayed on a large 80-inch TV in the operating suite and following surgery all of the data captured is imported into the traditional EMR program. The technology has been prototyped in two Houston Methodist O.R. suites so far and the hub aims to trial it in a simulation surgery by the end of the year.

Additionally, the hub is developing ambient listening technology to be used in a clinical setting with the same goal. Houston Methodist and AWS have partnered with Dallas-based Pariveda to create specialized hardware that (after gaining patient permission) will listen into doctor-patient conversations, transcribe the interaction, and draft a note that is then coded and imported directly into the EMR.

"For EMR the feedback is that it's clunky, it's click-heavy, it's very task oriented," says Josh Sol, who leads digital and clinical innovation for Houston Methodist. "Our goal with the Center for Innovation and this technology hub is to really transform that terminology and bring back this collaboration and the patient-physician relationship by removing the computer but still capturing all the pertinent information."

The ambient listening technology is further off and is currently in user acceptance testing with clinicians.

"They've had some great feedback, whether it's changing how the note is created, changing the look and feel of the application itself," Sol adds. "All feedback is good feedback at this point. So we've taken it in, we prioritize the work, and we continue to improve the application."

And the hub doesn't plan to stop there. Schwartz and Sol agree that the next step for this type of medical technology will be patient facing. They envision that in the near future appointment or surgery prep can be done through Alexa push notifications and medication reminders or follow up assessments could be done via voice applications.

"It's all going to be of tremendous value and it's coming," Schwartz says. "We may be taking the first baby steps, but each one of these voice technologies for our patients is out there on the horizon."

Report: Houston ranked No. 2 in the country for corporate relocation, expansion projects landed in 2019

big business

In Texas, Houston rules the corporate relocation and expansion kingdom.

Site Selection magazine ranks Houston second among large U.S. metro areas for the number of corporate relocation and expansion projects landed in 2019. That's up two spots from the previous year's ranking.

On the new list, published in the magazine's March issue, Houston replaces Dallas-Fort Worth in the No. 2 spot among metros with at least 1 million residents, pushing DFW down to No. 3. Austin takes the No. 6 spot.

Last year, Houston landed 276 projects that met the magazine's ranking criteria. With 416 projects, Chicago earned the No. 1 spot. Dallas-Fort Worth scored 261 projects in 2019, while Austin snagged 95.

Qualifying projects for Site Selection's rankings must have a minimum investment of $1 million, create at least 20 new jobs, or involve at least 20,000 square feet of new space.

A couple of notable Houston corporate relocations or expansions in 2019 were:

"This latest ranking is more evidence of Houston's strength as a destination for corporate relocation and investment," Bob Harvey, president and CEO of the Greater Houston Partnership, says in a March 3 statement. "Our low cost of doing business, access to quality talent, and pro-growth mentality continue to make Houston an attractive place for companies across the country and around the world looking for expansion and relocation opportunities. Our strong, diverse economy is a big part of what makes Houston a great global city."

Commercial real estate services company Colliers International notes that Houston is one of the country's most competitive cities for corporate relocation and expansion.

"Houston's ability to foster continued expansion in future-growth industries responsible for generating high-quality, well-paid jobs across all business sectors has placed it in the top tier among U.S. cities," Colliers International says. "With its numerous business advantages, Houston is well positioned to successfully compete in today's global marketplace."

Among those advantages, Colliers says, are:

  • Two major airports
  • Massive seaport
  • Extensive rail and road infrastructure
  • 90 foreign consulates

In February 2019, René Lacerte, founder and CEO of Bill.com, said the Palo Alto, California-based company picked Houston for its first U.S. outpost following an "extensive national search." Bill.com settled on Houston because of its talent pool, quality of life, and business-friendly environment, he said.

Houston Mayor Sylvester Turner has said the Bill.com expansion represents a "another great example of Houston's building momentum as a leading digital tech hub."

A second example is Amazon Web Services' July 2019 expansion in Houston. Kris Satterthwaite, the company's Gulf Coast enterprise sales leader, praised the city as "a fantastic place to live and work," and as having "a strong local economy that we look forward to investing in and growing together [with]."

The Houston-DFW-Austin trifecta of top-performing markets for corporate relocation and expansion in 2019 helped propel Texas to win Site Selection's Governor's Cup Award for the eighth consecutive year.

In accepting the award, Gov. Greg Abbott called Texas "the most dynamic economy in the nation."

"Texas' skilled, diverse, and ever-expanding workforce drives our booming economy," Abbott said. "I want to thank all of our local, regional and statewide economic development teams for their work to expand economic opportunity in Texas, as well as the companies that continue to invest and create more jobs throughout the Lone Star State."

Amazon opens newest Tech Hub in Houston and plans to hire

It's 'zon

A year and a half after Houston was left off the list of 20 cities Amazon was pursuing for its second United States headquarters, the tech giant chose the Bayou City to house its 18th North American Tech Hub.

Amazon opened the doors of the hub on Friday, July 26, in 25,000-square-feet of space in CITYCENTRE, and the company has plans to hire to round out its team of 150 Amazon Web Services employees to work out of the hub.

"We're looking forward to becoming a bigger part of the Houston community," says Kris Satterthwaite, Gulf Coast enterprise sales leader of AWS, in a release. "Houston is a fantastic place to live and work, and has a strong local economy that we look forward to investing in and growing together."

The city of Houston, along with the Greater Houston Partnership, has worked to make Houston appealing to big business and tech giants, says Susan Davenport, senior vice president of economic development at the GHP.

"The expansion of Amazon's Houston workforce is indicative of a larger trend we are seeing of the major cloud players opting to locate their teams closer to their customers here in Houston," Davenport says in an email to InnovationMap. "Our energy, life sciences and manufacturing sectors are data-intensive, and this move makes a lot of sense. This is not the first, and I doubt it will be the last. A great portion of the digital tech industry's activity to this point has been focused on business-to-consumer, and is now shifting to business-to-business. Houston is largely a B2B city, so we stand to gain from this trend."

The Tech Hubs in North America have over 20,000 employees. Around 1,000 of those are from Amazon's Austin Tech Hub, which opened around four years ago and was recently announced to be in the process of expanding to include another 800 Austin employees, per the Wall Street Journal.

The company has invested $10 billion into Texas since 2010, according to the release, and Houston's diversity, universities, and quality of life were attractive to Amazon.

"Houston is such a culturally diverse city, with so many international companies based here," says Eddie Murray, global accounts lead, in a release. "We're excited to create great jobs and hire locally to boost the local economy while also giving back to the community through programs like Amazon Future Engineer."

The Amazon Future Engineer program is an initiative to help propel kids from under-served areas into careers in computer science. The program is in 35 Houston schools. Amazon also provided disaster relief aid after Hurricane Harvey in 2017.

"We have worked for the last couple of years to accelerate the growth of Houston's digital tech ecosystem, and we've got quite a bit of momentum with The Ion, TMC3, The Cannon, and so many others," Davenport adds. "The opening of Amazon's tech hub is another indicator of Houston's growing presence as an innovation-focused city."

Texas is slowly but surely moving on up as an innovative state. According to Bloomberg's newest U.S. State Innovation Index, Texas is the 17th best state for innovation. The study factors in six metrics: research and development intensity, productivity, clusters of companies in technology, "STEM" jobs, populous with degrees in science and engineering disciplines, and patent activity. Last year, the study found Texas at the No. 19 spot.

Texas' score was 60.1 — which is just over a point's difference from being in the top 15. It's also worth noting that the Lone Star State is the highest ranked in the south.

"What is most important is the construction and catalyzation of super vibrant advanced industry sectors and clusters in a state," says Mark Muro, a senior fellow at Brookings, a think tank in Washington DC, to Bloomberg. "Commercialization has not been a top priority of universities in the heartland, especially in the South."

Houston brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.
