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.

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.

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.

Houstonian Steffie 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.”

Tomson was inspired to design the inaugural shoe for Getaway Sticks after her own struggle with heels, walking in the bustling Texas Medical Center from building to building for meetings. As a mom of two and a problem solver, she knew there had to be a better mousetrap. Click here to read more.

With an unstable energy grid, two Houstonians know at least one solution in the evolving energy industry: Microgrids.

Ed Pettitt and Paresh Patel co-founded InnoGrid, a social enterprise working to establish community microgrids in lower income areas — neighborhoods that are most at risk of devastating power outages.

"We want to convert the commercial microgrid model for low and moderate income and undresourced residential communities," Patel explains on the latest episode of the Houston Innovators Podcast. Click here to read more and stream the episode.

well heeled in comfort

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.”

Tomson was inspired to design the inaugural shoe for Getaway Sticks after her own struggle with heels, walking in the bustling Texas Medical Center from building to building for meetings. As a mom of two and a problem solver, she knew there had to be a better mousetrap.

“No other shoe offers this type of foam with the height that we offer it,” she says of the wedge-style shoe, which offers a wide toe box, soft suede material and limited height for stability and joint health.

With her scientist background, she would think about the “cognitive cycles” that get spent in dealing with schedules and matching corresponding footwear.

“’This shoe goes with this outfit, but does this shoe get me from this meeting back from the parking lot? Does it fit with the pant?’ It’s just an infinite decision tree of how to get your wardrobe aligned with the shoes — when all I ever wanted was a capsule collection of shoes that would just work for me all the time,” she says.

Typically, the fashion industry constructs shoes in a very traditional way, she says, and because of this, Tomson was met with much resistance from manufacturers to get the right materials for her prototype.

“I think there’s a lot of money that gets thrown around trying to get women to buy shoes,” says Tomson. “Those may or may not be comfortable. There’s just not enough being poured into getting women to buy shoes that’s really been designed for us with us in mind.”

Getaway Sticks went through the gBETA accelerator last spring, which helped springboard the company and connect Tomson with the local innovation ecosystem.

“There aren’t many people who are making shoes in Houston, but there’s a lot of support for cool ideas and novel thinking here,” she says. I’m glad that I’ve been made aware of them and invited into these groups.”

Now past its first pre-seed phase and prepping for its initial round of seed funding in 2023, Getaway Sticks is looking ahead at its next shoe launch in the coming months — the ballet flat.

“I think that we as women can identify with the fact that we all have a really beautiful pair of heels and they are almost certainly not going to be comfortable,” she says. “And we may have a really comfortable pair of heels, but they are not always the cutest thing in our wardrobe. We always have to kind of flip and decide. I just felt strongly that we needed something to make our lives simpler.”

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.

Battery tech startup Casimir develops semiconductor chips that produce continuous electrical power straight from the quantum vacuum, without the need for a battery, cord or external charge source. The company is targeting commercialization for its first-generation MicroSparc chip by 2028.

Harold “Sonny” White founded Casimir in 2023 after nearly two decades at NASA. The company emerged from stealth with a $12 million seed round in 2026. It was also awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force earlier this year.

FocisAI

Artificial intelligence startup FocisAI helps refinery owner-operators unlock actionable insights from 3D scans and images.

FocisAI was founded by CEO Tyler Wooten, COO Colin Snell and CTO Kyle Snell in 2026. It is a member of Greentown Labs and launched a seed round in September, which is expected to close by the end of the year, according to the company's application. It has rolled out 10 pilot programs and is looking to move into recurring, facility-scale deployments and scale its team in Houston this year.

Machine Saver Inc.

Industrial tech startup Machine Saver Inc. builds wireless and wired vibration and proximity sensors to tell heavy industry when a machine is about to fail. The company's technology runs on an 8-plus-year battery life and helps operators reduce downtime, improve maintenance and extend equipment life.

Machine Saver was founded by CEO Colton Bach and Quentin Bach in 2013. Its customers and partners include Houston Methodist, Blue Bell, Genemco, as well as energy and heavy industry, food and beverage, and cold chain companies, according to its application. The company is raising a Series A.

Square Robot

Energytech startup Square Robot develops and operates submersible inspection robotics that inspect aboveground storage tanks while they remain in service. The robots reduce downtime and costs, improve worker safety and limit hydrocarbon emissions.

Square Robot launched its Houston office in 2019 and closed a Series B in 2025. It plans to complete its first U.S. Navy demonstrator tank in November and is also developing real-time inspection software.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

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.
