Fans across the country are headed to football stadiums this weekend to cheer on their teams, but only a few will have the luxury of ordering food, beer, and even merchandise from the comfort of their seats.

Houston-based sEATz has created a platform where fans can order just about anything their stadium has from an app. Much like any other ordering app, once the order is placed, a runner will pick up the food and deliver it to the customer for a small fee and a tip.

The startup is now preparing to scale up from seven venues to 10 before the year is over as well as launching a new version of the app thanks to an oversubscribed near $1.3 million Seed round led by Houston-based Valedor Partners. Houston-based Starboard Star Venture Capital also contributed to the round. SEATz has plans to launch its Series A round before the new year. To continue reading this top story, click here.

Three powerhouse investment minds have teamed up to launch a female-focused seed and series A venture capital firm in Houston.

In its first $20 million fund, The Artemis Fund will invest in around 30 women-led companies, and will award a $100,000 investment prize at the Rice Business Plan Competition, which takes place April 4 through 6. According to the company's press release, The Artemis Fund is the first of its kind — being female-led and female-focused — in Houston.

"There is a wealth of female leadership in the Houston innovation ecosystem, and we would like to see the same representation in the investor the investor community to help female founders thrive," says Stephanie Campbell, co-founder and principal of The Artemis Fund.

Texas venture capital deals had a slow quarter, according to Crunchbase data. Getty Images

Houston sees underwhelming venture capital funds in Q3 2019, following larger Texas trend

funding fumble

The entire state of Texas saw an unimpressive third quarter of venture deals — especially compared to the second quarter's reports — and Houston was not immune.

The state reported $372.4 million fundraised by tech startups in Q3 of 2019, according to Crunchbase data, which is less than half of what was reported in Q3 of 2018 ($776.8 million) and what the state raked in the second quarter of this year ($830.6 million).

Houston brought in a measly $38.4 million last quarter, per Crunchbase, and compared to the $251 million raised by Houston companies in Q2, that drop stings. It's the lowest quarterly venture amount Houston's seen in over a year, and lower than Houston's $44.7 million reported for Q1. Zooming out a little, the city's venture reports remain a rollercoaster of sorts with strong quarters bookended by lousy ones.

Chart via InnovationMap using Crunchbase data.

Austin maintained its top spot on the Texas venture leader board with $236.4 million of Texas' total $372.4 million raised in Q3 2019, according to Crunchbase, but that's about $200 million less than the city raised in Q2. Meanwhile, Dallas — a city Houston usually competes with for the No. 2 spot — raised $70.3 million compared to its $126.7 million raised in Q2. The only region up in raises is categorized as "other Texas metros," which went from $7.3 million to $27.4 million between Q2 and Q3.

According to Crunchbase, the city's $38.4 million was raised in six deals between June and September 2019. The top deal of those six companies was raised by Axiom Space, which closed a $16 million in a seed round.

Crunchbase's Texas reporter, Mary Ann Azevedo, reminds readers that their proprietary data is subject to reporting delays.

"Actual deal counts and dollar volume totals are higher than what Crunchbase currently has on record, and the numbers we're reporting today are likely to change as more data gets added to Crunchbase over time," she writes.

Just like Crunchbase, InnovationMap doesn't get to report on every single venture deal. However, here are some of the raises we covered in the third quarter of this year.

Texas Halo Fund led a Houston startup's seed round last month. Galen Data, which uses its cloud-based software to connect medical devices, closed a $1 million seed round thanks to the fund's $250,000 investment. Kevin King, one of Texas Halo Fund's managing director, has also been named to the startup's board of directors.

According to the release, the Texas Halo Fund based its decision for the investment "on the large and growing addressable market of connected medical devices, the company's impressive management team, and post revenue status."

Galen Data's emergence comes as the market for internet-connected mobile health apps keeps growing. One forecast envisions the global space for mobile health exceeding $94 billion by 2023.

"We want to be at the forefront of that technology curve," DuPont tells InnovationMap in a previous interview. "We might be six months early, we might be a year early, but it's starting to happen."

Earlier this year, Galen Data formed strategic partnerships with medical device companies. Click here to read more about those.

SurfEllent

SurfEllent, an anti-icing coating technology startup founded out of the University of Houston has raised $470,000 in funding. The company won the second place award and a total of $45,000 at the Texas A&M New Ventures competition before receiving an anonymous investment of $350,000 in seed funding. SurfEllent also received two grants: a $50,000 Small Business Innovation Research grant and a $24,999 Small Business Technology Transfer grant.

"Ice is a problem that will exist as long as we live on the earth. It impacts a wide range of things, including aircraft wings and engines, automobiles, buildings and bridges, ships and vessels, and power transmission systems," says SurfEllent Co-Founder Hadi Ghasemi, a Bill D. Cook Associate professor of mechanical engineering at the UH Cullen College of Engineering, says in a news release.

SurfEllent's product can be used in the de-icing of cars and airplane engines.

"The end goal is to improve the quality of human life," Ghasemi says in the release. "This recognition is another proof of the critical need for advanced anti-icing coating technologies and opens opportunities for collaboration with various industries and business partners."

Cemvita Factory

In August, Occidental Petroleum's Oxy Low Carbon Ventures LLC invested in Houston-based Cemvita Factory, and in September, BHP followed suit. While Cemvita Factory isn't able to disclose how much money its raised through these partnerships, the company confirms it has closed its round of funding.

Cemvita Factory is run by a brother-sister team. Moji and Tara Karimi built the company off of Tara's research into mimicking photosynthesis. The process is able to help reduce energy company's carbon emissions.

"We have an ambitious goal to take one gigaton of CO2 out of the carbon cycle in the next decade and are very excited about being a part of Occidental's journey to become a carbon-neutral company," says Tara, co-founder and chief scientist, in a news release.

The investments will help Cemvita Factory continue to develop its biomimicry technology for oil and gas applications to reduce the volume of greenhouse gas emissions.

Sourcewater

Houston-based Sourcewater Inc., which specializes in oilfield water intelligence, closed its series A round at $7.2 million. Bison Technologies, Marubeni Corp., and major energy family offices in Houston, Midland, Dallas, and Oklahoma City contributed to the round. The funds will go toward further developing the company's technology.

"For every barrel of oil produced in the Permian Basin there are more than ten barrels of associated water that are sourced, recycled, transported, and disposed of," says Joshua Adler, founding chief executive of Sourcewater, in a news release. "When America became the world's leading energy producer last year, it also became the world's leading water producer, times ten. Water management is now the majority of upstream energy production cost, and water sourcing, recycling and disposal capacity is the primary constraint on America's energy future."

SEATz

Houston startup sEATz has created a platform where fans can order just about anything their stadium has from an app. Much like any other ordering app, once the order is placed, a runner will pick up the food and deliver it to the customer for a small fee and a tip.

The startup is now preparing to scale up from seven venues to 10 before the year is over as well as launching a new version of the app thanks to an oversubscribed near $1.3 million seed round led by Houston-based Valedor Partners. Houston-based Starboard Star Venture Capital also contributed to the round. SEATz has plans to launch its Series A round before the new year.

"We're building enterprise-level, scalable in-seat ordering, delivery, and pick-up software. We'll have all the data and validation we need this fall to really start to push that out," says CEO and co-founder Aaron Knape.

Syzygy

Using research that came out of Rice University, Syzygy Plasmonics has developed a hydrogen fuel cell technology that produces a cheaper source of energy that releases fewer carbon emissions.

The company just closed a $5.8 million Series A round led by MIT's The Engine and Houston-based The GOOSE Society of Texas. Evok Innovations, a previous investor in the company, and angel investors from the Creative Destruction Lab also contributed to the round.

"We're starting to solidify relationships and get customers ready," CEO Trevor Best tells InnovationMap.

Topl

Houston-based Topl, a blockchain network with applications across industries, closed a 20 percent oversubscribed $700,000 seed round.

"Every investor that is invested now has focused on both the purpose and the profit, and I'm big on that," Kim Raath, president and co-founder of Topl, says.

The team has built six blockchain platforms that operate on the Topl network — two are live now, and four will go live later this year. The platforms are focused on four different areas: agriculture (tracking food products from the farm to the shelves), mining (diamonds, for instance), sustainability and impact (tracking a program to see how it succeeds), and carbon credits and renewables within the energy industry.

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.

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.
