Mayor John Whitmire and Houston First Corporation shared a new master plan for the George R. Brown Convention Center and its surrounding area last week. The plan features expanded exhibition space, a living roof, a pedestrian plaza with access to Toyota Center and more.

The project will be funded by the state’s portion of incremental Hotel Occupancy Tax revenue growth within a three-mile radius of the GRB for 30 years, which is estimated to total about $2 billion, according to a release from Houston First.

The first phase of the project, which is slated to be completed by 2028, will focus on developing a 700,000-square-foot convention facility known as GRB South.

GRB South will feature:

  • Two exhibition halls, totaling 150,000 square feet
  • A 50,000-square-foot multipurpose hall that opens to the new Central Plaza
  • The 100,000-square-foot Central Plaza, an extension of the Avenida Plaza that will connect to Discovery Green and Toyota Center
  • Atrium flex hall totaling 25,000 square feet
  • 225,000 square feet of contiguous exhibit space
  • A 60,000-80,000-square-foot ballroom
  • Ground-level spaces for retail and restaurants
  • A central atrium, providing each level with natural light

The design of the space is inspired by the Houston area's native prairies and will use low-carbon materials, high-efficiency building systems with rainwater collection and water-reduction strategies. A living roof on top of the GRB South will also have the potential for solar integration.

"It is imperative for us to stay competitive and meet the needs of our meetings and convention customers,” Michael Heckman, president and CEO of Houston First, said in the release. “This project will not only accomplish that but will establish a gathering space that will be the epicenter for entertainment, sports, and city-wide events, accentuating our ability to capitalize on Houston's unique offerings.”

The full campus renovation is expected to wrap in 2038, and construction will be managed in phases. Houston First reports that construction should not impact events currently scheduled as GRB.

“This project is truly transformative for downtown Houston, a lasting legacy that will solidify our position as a top-tier convention and entertainment destination,” Mayor John Whitmire said in the release. “Most importantly, we are creating a space that will build community, foster connection, and shape the future of Houston.”

Houston to host inaugural ESPN collegiate esports competition

Game on

For the first time ever, ESPN is hosting the Collegiate Esports Championship, and it's chosen Houston's 11th annual Comicpalooza to host it on May 10 to May 12 at the George R. Brown Convention Center.

"We are honored ESPN has chosen Houston and Comicpalooza for their inaugural Collegiate Esports Championship," says Michael Heckman, Comicpalooza president and senior vice president at Houston First, in a release. "Each year we strive to provide unique experiences for our different pop culture fandoms. Esports is undoubtedly popular and expanding. Teaming up with ESPN to bring the CEC here allows us to engage our audiences in a completely new, exciting way."

Students from hundreds of schools have competed to make it to the semifinals and championship in Houston, and scholarships are on the line. The weekend will have 22 teams across five video games — Hearthstone, Heroes of the Storm, Overwatch, StarCraft II, and Street Fighter V — according to ESPN.

"As universities continue to grow their esports programs at the varsity, non-varsity and club levels, we're proud to be providing a platform for national exposure and recognition of some of the most talented players in the collegiate space," says John Lasker, vice president of Digital Media Programming for ESPN, in a release. "Through our collaboration with top publishers in the industry, players will be able to showcase their talent in high-level competition on some of the most prominent esports titles."

Attendees and fans have access to the events with a Comicpalooza pass, but can also opt for the conference's Gaming Speed Pass for extra perks like reserved seating, a private lounge, and opportunities to meet the talent. Conference goers can also compete themselves in several different video games, according to the website.

Houston is a growing hub for esports. Mainline, a spin off company of Houston-based sports marketing company FanReact, launched this year to account for the growing presence of esports. Mainline's CEO, Chris Buckner, tells InnovationMap in an interview earlier this year that, especially because of this ESPN competition, other cities have their eyes on Houston for esports.

"I have been personally in contact with every major university in the city and they all are taking esports seriously," Buckner says in an interview. "It's actually a really exciting time for esports in Houston."

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.

Casimir

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.
