Houston-based health tech startup is revolutionizing patient selection for clinical trials

On many occasions in her early career, Dr. Arti Bhosale, co-founder and CEO of Sieve Health, found herself frustrated with having to manually sift through thousands of digital files.

The documents, each containing the medical records of a patient seeking advanced treatment through a clinical trial, were always there to review — and there were always more to read.

Despite the tediousness of prescreening, which could take years, the idea of missing a patient and not giving them the opportunity to go through a potentially life-altering trial is what kept her going. The one she didn’t read could have slipped through the cracks and potentially not given someone care they needed.

“Those stories have stayed with me,” she says. “That’s why we developed Sieve.” Read more.

A female-founded biotech startup has announced that it has received a grant from the Bill & Melinda Gates Foundation.

Steradian Technologies has developed a breath-based collection device that can be used with diagnostic testing systems. Called RUMI, the device is non-invasive and fully portable and, according to a news release, costs the price of a latte.

“We are extremely honored to receive this award and be recognized by the Bill & Melinda Gates Foundation, a leader in global health. This funding will propel our work in creating deep-tech diagnostics and products to close the equity gap in global public health," says Asma Mirza, CEO and co-founder of Steradian Technologies, in the release. “The RUMI will demonstrate that advanced technology can be delivered to all areas of the world, ensuring the Global South and economically exploited regions receive access to high-fidelity diagnostics instead of solutions that are ill-suited to the environment.” Read more.

With the Houston Marathon only five months away, a new application using human motion insights could help a runner refine their form to reach peak performance – all from the convenience of their smart phone.

While traditional treadmills are limited in training feedback and wearables are not designed to track elevation, Houston-based AiKYNETIX uses real-time technology to provide a new option for runners on treadmills.

“Runners spend a lot of time, energy and money to run better,” says Denis Akhiyarov, CEO and co-founder. “In my personal life with training for nine marathons, I’ve seen limitations with wearables, they don’t actually track running form while running. Overall, our technology tracks not only your basic parameters but it can also analyze the human running form while in motion.” Read more.

Local startup to upgrade EV charging in Houston and beyond

At 3 a.m. one night, just as he had many nights before, Tarun Girish found himself leaving his Houston apartment in search of an EV charger.

Once he located one, he would sit in his car for an hour and a half while his vehicle charged — with not much to do but wait.

But it was on this night he wondered if there was a way to use his previous hospitality experience to build a new kind of experience for EV drivers. He then developed his first iteration of a business plan — all while sitting in his driver’s seat.

His idea became Sparks Spaces, a startup formed in 2021 looking to shake up the EV charging game — the company aims to elevate the experience of charging electric vehicles by focusing on the space between car and charger by creating an airport lounge-type space for drivers. These EV lounges would include luxury waiting areas, clean restrooms, high-end food options, and availability to utilize them 24/7. Read more.

Houston neuroscientist turned startup founder takes steps toward comfier shoes

Two and half years ago, native Houstonian Steffie Tomson ordered $2,000 worth of shoes and sliced them all in half with a bandsaw just to see what was inside.

Tomson, a neuroscientist by trade and the founder and CEO of footwear startup Getaway Sticks, had an idea for a different kind of shoe — one that was redesigned to prioritize women’s comfort.

“I thought, ‘why can’t we start with a sneaker material and then build a heel around it?’” she tells InnovationMap. “I started just slicing everyone else’s shoes and now I’m more convinced than ever that our shoe is different.” Read more.

4 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to four local startup founders across industries — from electric vehicles to app development— recently making headlines in Houston innovation.

Jeff James, co-founder and CEO of PickleJar

Jeff James had the idea for a platform that allows musicians to engage with their audiences — specifically when it came to receiving tips. Right when he started working on the idea for PickleJar, an app-based, performer-focused platform where fans can conduct cashless tips, the pandemic hit.

"As the pandemic lingered on, we realized the project wasn't just about tipping or on-stage engagement, it's about something greater than that," James says on the Houston Innovators Podcast. "It's all the different ways how artists are being disenfranchised. We really set out on a mission to help artists make more money."

As distracting as the pandemic was at first to PickleJar, which officially launched in May of 2021, the company ended up having a huge opportunity to be a revenue stream for artists when they needed it most. The duo decided they had to build the company — even during the pandemic and uncertain times. Click here to read more and listen to the episode.

Clutch, a digital marketplace startup founded by Simone May and Madison Long, has fresh funding after closing its pre-seed round of funding at $1.2 million. The investment from this round will support Clutch’s national open beta launch of its platform for brands and student creators nationwide and its continued investment in customer and product strategy.

“We are at this inflection point where marketing is changing,” May says in a press release. “We know that the next generation can clearly see that and I think a lot of marketing agencies are starting to catch on.

"We need to be prioritizing the next generation’s opinion because they are driving who is interested in what they buy. This upcoming generation does not want to be sold to and they don’t like inorganic, inauthentic advertisements. That’s why user generated content is so big, it feels authentic.” Click here to continue reading.

Tarun Girish wanted to upgrade EV drivers' charging experiences. His idea became Sparks Spaces, a startup formed in 2021 looking to shake up the EV charging game — the company aims to elevate the experience of charging electric vehicles by focusing on the space between car and charger by creating an airport lounge-type space for drivers. These EV lounges would include luxury waiting areas, clean restrooms, high-end food options, and availability to utilize them 24/7.

“We’ve seen a huge issue in the EV charging space where the experience side has been neglected,” says Girish, founder and CEO of Sparks Spaces.

Currently, Sparks Spaces is operating out of The Ion and installed a charging point outside of the building to help collect insights into what drivers are needing and are wanting to learn more about their customer base. Click here to learn more.

Currently, Sparks Spaces is operating out of The Ion and installed a charging point outside of the building to help collect insights into what drivers are needing and are wanting to learn more about their customer base.

Eventually, the company’s goal is to take forgotten buildings and transition them into becoming EV charging hubs.

“The Ion is giving us a lot of resources to make sure that we are tailoring the solution to the right problem,” he says. “We’ve learned how to build a frictionless experience where the driver scans a QR code, pays for the duration of the charging session and then plugs in.”

When Sparks Spaces scales out, the team is eyeing two locations inside The Loop — one in Montrose and one on Shepherd Drive. The design would focus on natural lighting, safety and security.

The startup went through the Smart City Ion Accelerator but will be applying to a couple more accelerators that have more exposure into the EV construction space.

“We’re trying to provide a brand consistent experience from the time a driver drives into a lot to the time they leave,” he says. “We’ll be providing all fast-charging and level 2 charging services for drivers and will be completely universal so that any EV can utilize us.”

Sparks Spaces is looking to raise a $1.1 million seed round that will focus on research and development, the case studies and the architectural designs for a prototype that can be implemented in its locations.

“We want to be the definition of charging and lounges and experiences should be the forefront of EV charging,” he says. “The average household who owns an EV expects a certain level of luxury and expectations on experience. They are used to airport lounges when traveling. We want to reflect that in the EV charging space.”

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
