Houston-based company is connecting the dots on patient referrals

Diagnosing doctors

When your doctor recommends that you visit another practitioner, it's only natural that you trust the suggestion. But it's one case in which your physician isn't always an expert. Married doctors Justin Bird, an orthopedic surgeon, and Terri-Ann Samuels, a specialist in female pelvic medicine and reconstructive surgery, have long noted that patients are often referred incorrectly.

No big deal, right? Just go to another doctor. But not everyone has that luxury. Bird and Samuels never intended to start their own company. But when Bird lost a patient due to faulty referrals, they knew something had to be done.

"He believes that if she hadn't been bounced around from doctor to doctor, they could have saved her life," says Chris E. Staffel, chief operating officer of Patients We Share, the app that the couple created to fix the broken aspect of the health care system.

In 2015, Bird and Samuels began their company when they were shocked to realize that such an app didn't already exist.

"They started working with physicians around the country who said, 'We really, really need this,' and they also invested in it," recounts Staffel. From those friends, they built a physician advisory board of 15 investors.

Prescribing growth
The project was accepted into Johnson & Johnson's incubator, JLABS in 2016, then TMCx's digital startup program in the spring of 2018.

"They started realizing it was gaining momentum and realized they needed to have business people on board," says Staffel.

They hired Michael Antonoff, a Rice University M.B.A., as CEO. He invited former classmate Staffel to join as COO. Having come from a background in oil and gas, Staffel jumped at the chance to try her hand in a different industry.

With new business clout behind PWS, the company is growing quickly. Currently, PWS is entering its next seed round of $2.5 million that will allow the company to pay salaries of new team members and bring some tech development in-house. Until now, the making of the app itself has been outsourced to Mobisoft Infotech, a company based in Houston and India, which has worked on many projects at the Texas Medical Center. Local Black + Grey Studio is responsible for the design.

PWS has been working with both those teams in recent months to get a prototype app ready for launch. Currently, 100 physicians around the country are part of an invite-only pilot program. Soon, Staffel hopes to allow early adopter doctors who haven't been invited to enroll in the program for free. It will likely be in 2020 that patients will start joining the community, too.

How it works
An index of all the providers on the app allows doctors to easily find practitioners in a particular specialty. But there's more to it. Detailed profiles contribute to machine learning that assures the optimal match every time. Patient reviews will also play a role.

Though referrals were the impetus for the creation of PWS, it may be even more important as a communication tool between doctors, fellow clinicians (anyone from nurse practitioners to physical therapists may be invited to join), and patients. Staffel says participants in the pilot program are already using the messaging system to compare notes on cases, even sending photos from surgery to consult on patient issues.

The app's encryption means that it's HIPAA-compliant. Patients provide permission to discuss their cases via the app. And they can be confident of the quality of care they'll receive. Likely, the app will remain largely invite-only, and everyone who joins will share their National Provider Identifier licenses to be vetted against the federal database.

Doctors will communicate directly with patients through the app, but will also share resources digitally. Instead of making copy after copy of information about post-surgical care, for instance, the physician need only press a button to share a link.

Eventually, the goal is for PWS to be used not just nationally, but internationally, not just by individuals, but by whole hospital systems. A world in which doctors can compare notes around globe could be a little safer for us all.

Orion vehicle manager reflects on Artemis II, looks to 2028 moon mission

Q&A

Humanity is finally headed back to the moon after more than half a century. This year's launch of the Artemis II mission in the Orion spacecraft put four crew members in lunar orbit and tested the new ship developed by Lockheed Martin.

Everything went smoothly, safely returning astronauts home, but there is always room to improve. InnovationMap chatted via email with Orion vehicle manager Branelle Rodriguez, shortly after a talk at The Ion, for insight on how Orion might perform in the future as the next lunar landing approaches in early 2028.

InnovationMap: How satisfied are you with the way Orion operated on this past mission?

Branelle Rodriguez: Orion performed exceptionally well during Artemis II, successfully demonstrating critical spacecraft capabilities, including life support systems, displays and controls, and executing manual piloting operations. Artemis II brought humans back to the moon, achieving key exploration and scientific imagery, while validating systems essential for future Artemis missions.

IM: What is the most important thing you learned about improving Orion for the next mission?

BR: The Artemis II mission provided invaluable insights into crew operations and spacecraft performance in a deep-space environment. With every mission, NASA applies lessons learned to continuously improve Orion’s operations, validate design and ensure mission readiness. Artemis II offered our first opportunity to evaluate several new systems and gain a deeper understanding of what it is like for astronauts to live and work inside the spacecraft. The operational, technical and human factors data collected are being integrated across the program to refine future missions, reduce risk and enhance overall mission success.

IM: How has Orion helped the mission to explore space?

BR: Orion is one of NASA’s foundational elements for human deep space exploration—not only supporting the mission but serving as a core component of it. It is currently the only spacecraft capable of carrying crew on deep space missions and returning them safely to Earth from the high speeds required from the vicinity of the moon. No other spacecraft has the technology to endure the extremes that come with human deep-space travel, such as advanced environmental and life support, navigation, communications, radiation shielding, and the world’s largest ablative heat shield to protect the astronauts during reentry into Earth’s atmosphere. Orion has already taken astronauts to explore space farther than ever before—252,756 miles from Earth— and will carry crews to the moon on future missions to explore the lunar South Pole region. The astronauts’ observations, samples, and data collected on these future missions will expand our understanding of our solar system and home planet.

Houston VC funding nears $1B in first half of 2026, report says

by the numbers

Despite a weak second quarter, venture capital funding for Houston-area startups approached $1 billion in the first half of 2026, the region’s highest first-half total since 2022, according to the latest PitchBook-NVCA Venture Monitor.

This year’s first-half total of $962.4 million represented a nearly 8 percent increase over last year’s first-half total of $891.7 million. Dating back to 2016, this year’s first-half haul lags behind only 2021 and 2022 for the most first-half funding.

Houston’s year-over-year VC jump of 73 percent in the first quarter of 2026 more than made up for the year-over-year drop of 34 percent in the second quarter of 2026, according to the report.

Deal count tells a more encouraging story: Houston startups closed 102 deals in the first half, up from 93 a year earlier and the region’s busiest first half since 2022. However, the average deal size shrank, as no single funding source dominated the total.

Keep in mind that PitchBook and NVCA routinely revise quarterly numbers upward to reflect deals that were reported after a previous quarter’s data was published. So, in the case of Houston, numbers initially reported for the first quarter of 2026 may not match newly reported numbers.

Perhaps the most notable Houston-area deal announced in the first half of this year was Cart.com’s $180 million growth equity investment, led by Springcoast Partners. Cart.com is an e-commerce platform and logistics provider.

PitchBook-NVCA data shows Houston’s VC activity is growing modestly, delivering better numbers in the first half of 2026 versus 2024 and 2025, but it still sits below the highs of 2021 and 2022. This is one sign that so far in 2026, the national VC boom isn’t benefiting non-hub markets like Houston the way it’s boosting some hub markets, especially Silicon Valley and New York City.

Nationwide, AI dominated VC funding in the first half of this year. The sector made up 86 percent of VC from January through June. The report notes that the markets have still struggled to unlock IPOs, with SpaceX being the biggest exception, and few M&A deals outside health care have been significant.
