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.

“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.

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.”

This tech startup envisions Houston as a self-driving city

smart cities

When there isn't a global pandemic, nearly 7 million people drive around Houston, and an estimated 77,000 people commute for more than an hour and a half to work. Drivers spend $1,376 and waste 31 gallons of fuel a year — to sit in traffic for what adds up to 75 hours each year.

When Wilson Pulling moved to the city two summers ago, he set out to fix all that traffic-sitting using autonomously driven cars, but not the high-priced ones that Uber and Tesla have designed. These are your regular, three- or four-year-old Honda Civics and Kia Sorentos — the cars you already own.

In 2016, Pulling founded had Aatonomy with his partner, Yang Hu, based on their thesis work from Cornell's Computer Science program. Moving the company south after two years operating out of San Francisco, they aimed not to build the self-driving car of the future, but to make the cars that Houstonians are wading through congested freeways in today drive themselves.

"Everyone doesn't get to buy a Tesla. They're driving their Corollas," Pulling says. "The way autonomy is going right now, that person is never going to benefit. We are the only way."

The company's technology attaches a wireless receiver to the car, which has to be from at least 2016 to work with them. Then, Aatonomy places sensors all along the roads and streetlights. The sensors and receiver communicate with each other, and enable autonomous driving.

Imagine, Pulling says, a 30-mile of I-45 with Aatonomy's sensors. You'd roar up the freeway, handling the controls. Then, the car's computer, under guidance from Aatonomy's network of sensors, would take over. You'd sit back, the car will navigate the traffic along with the other cars — and if all the cars are autonomous, Pulling says, the algorithm could slash congestion. When your car exits the freeway, you'd take back control.

That stretch of freeway would cost $26 million for 200,000 commuters across Houston, Pulling says, but other self-driving cars cost around $250,000 per vehicle — summing up to $50 billion for those same commuters. And Pulling says the Aatonomy system is a safer bet than the way Uber's autonomous driving. Uber's car once killed a pedestrian because, somehow, the company didn't program it to avoid people jaywalking. But because Aatonomy will manage sensors all over the street, the company will be able to monitor potential accidents more quickly than an Uber car would.

"This is a really radically different approach to a technology that, frankly, a lot of people have lost a lot of faith in," Pulling says.

Aatonomy's approach requires a smart city commitment — but the city of Houston is already buying in. First, Aatonomy, a member of the Ion Smart and Resilient Cities accelerator's inaugural cohort, got a short-term project with Aatonomy and Verizon to mount intersection cameras for studying how to prevent collisions with pedestrians on the Northside.

Additionally, the city has also greenlit a two-year pilot with Aatonomy to automate a bus route in downtown Houston. The aim, Pulling says, is making a "proof-of-concept" before rolling out sensors across I-45 — but it's also to use Houston as proof that autonomous driving can be achieved, but from a different angle than Uber.

"Self driving cars don't work. That's our thesis," Pulling says. "That's why we're building self-driving cities."

Houston accelerator announces newest cohort to tackle cleantech

Smart cities

As the world celebrated the 50th annual Earth Day on April 22, a Houston innovation organization announced a new group of startups for its accelerator program that will focus on cleantech solutions within the city of Houston and beyond.

The Ion's accelerator, which recently renewed its focus on resiliency, announced its second cohort with six startups that will create solutions for Houston's air quality, water purification, and other cleantech needs.

"Through leveraging the power of our local Ion community, The Ion Smart and Resilient Cities Accelerator is committed to solving challenges Houstonians face every day," says Christine Galib, senior director of accelerator programs at The Ion and the director of the accelerator, in a news release. "We connect participating startups with mentors, partners, and stakeholders, so they gain access to the resources they need to build, validate, and scale their technologies. Together, we are building a safer, smarter, and more accessible city for all Houstonians."

The program is supported by Intel, Microsoft, and TX/RX and has began its programming for the new cohort. The six startups selected for the program are:

  • Houston-based Eigen Control uses machine learning and chemical engineering models to combat rising CO2 emissions. Distillation process plants emit so much CO2 — and Eigen Control's processes are working to change that.
  • Houston-based Annapurna Solutions has cloud-based solutions for hazardous and solid waste management.
  • Mexico City-based S2G Energy focuses on sustainable and optimized solutions for businesses and governments with its energy-management-as-a-service technology.
  • Houston-based re:3D is a 3D-printing nonprofit that is democratizing small-scale manufacturing. Its Gigabot can use recycled and reclaimed materials for more sustainable and affordable production. The company, which has offices in Puerto Rico and Austin, donates a printer to someone making a difference with every 100 printers it sells.
  • Austin-based LifePod Corps is a nonprofit that provides disaster relief through renewable and sustainable technologies built and delivered by military veterans.
  • Houston-based Water Lens has created a real-time water data analytics platform for industries that use a lot of water — like oil and gas, agriculture, power generation, coal mining, and food processing. The technology allows for quicker, more reliable results.

The accelerator's leaders chose its theme for the cohort based on the City of Houston's Resilient Houston Strategy and Climate Action Plan. The program has identified these six startups as movers and shakers within these Smart Cities challenges.

"We are thrilled to collaborate with these startups to further develop Houston as one of America's smartest and most resilient cities," says Gabriella Rowe, executive director of The Ion, in the release. "By leveraging our resources and networks, the accelerator and Cohort 2 improve living conditions for all Houstonians. In this way, we stimulate our local economy with new jobs and economic opportunities."

Last year's inaugural cohort was announced in August and focused on resilience and mobility. After a demo day in December, the cohort continued its work in Houston through 15 pilot programs the startups had with the city. The third cohort is expected to launch toward the end of 2020, but the next theme has not yet been decided.

Philanthropic supply chain tool connects Houstonians with resources during coronavirus crisis

oh the umanity

A Houston startup that has been working in a pilot program capacity with the city of Houston has accelerated the rollout of its platform to help connect and coordinate people's needs to resources in real-time during the coronavirus outbreak.

Umanity, which is a part of the Ion Smart and Resilient Cities Accelerator's first cohort, has created a philanthropic supply chain tool that's now available as an app or through desktop. The software can match and map local individual or nonprofit needs to organizations or volunteers, plus provide real-time analytics. During the coronavirus outbreak, they have mobilized its resources connecting supplies with nonprofits and volunteers with safe ways to help organizations that need it most during this crisis.

The Ion Smart and Resilient Cities Accelerator launched in 2019 to provide technology-driven solutions to Houston's most prevalent challenges. The accelerator is backed by Intel and Microsoft and partnered with the city of Houston and Station Houston.

"Our first cohort focused on transportation, resiliency, and connectivity," says senior director of the Ion Smart Cities Accelerator, Christine Galib. "It was tightening much of the ways in which a vast and expansive city like Houston can come together and feel connected and supported as a city."

These themes are exemplified by Umanity, who is working with several city of Houston officials to direct citizens the resources they need during the crisis, and creating a network of communities to efficiently provide them the resources they need. The centralized platform shows a complete picture of who needs help and who can help all on the same platform while measuring the real-time economic impact of donations and every volunteer hour.

"I started this company because I wanted to transition everyday acts of service into actual data-driven solutions," says Ryan-Alexander Thomas, CEO and founder of Umanity. "My goal is that during the next crisis, for example, hurricane season, if somebody needs something they have access to get it when they need it, not two years later or after the crisis."

The platform has already rolled out in other cities such as Hyattsville, Maryland, to help connect their network of nonprofits with individuals as part of their crisis response as a result of supply shortages due to the coronavirus pandemic.

With the help of their accelerator, Umanity is currently working with a number of the city of Houston's mayor's directors, including education and health leaders to create a broader coalition designed to collaborate and coordinate more efficiently by aggregating information from these sources.

"Having some of the mentors in the accelerator put us in touch with decision-makers in the city has really given us the boost we need to get a chance to show that we can do something good for the people and the community," says Thomas.

Thomas says Umanity is ready to be implemented in a dozen cities in the next few months. Their team is already close to signing partnerships with additional municipalities across the country.

"Our platform is available right now for download and we're growing," says Thomas. "We've tripled the number of organizations in the past week and we are always looking for new nonprofits, churches, and organizations to partner with to help those in need."

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.

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.
