A Houston software company is cashing in on the growing esports industry with a multimillion-dollar fundraising round led by a local investor.

Mainline, which specializes in esports tournament software and management, closed its series A at $6.8 million. Houston-based Work America Capital led the round, and Mainline will use the funds to grow its platform, event management customer base, and marketing efforts, as well as to hire developers, marketing, and sales talent.

"The world of esports and gaming is exploding; however, continuity in tournament organization is lacking, keeping the sport from really taking off in other viable and exciting markets," says Chris Buckner, Mainline CEO, in a news release. "Mainline gives brands the tools they need to run powerful esports programs that will evolve the quickly maturing industry to the benefit of players, students, and the greater esports ecosystem."

Mainline, which spun off its sports engagement business earlier this year into a company now called Truss, created a white-labeled tournament platform for esports that's used by various clients across the industry and was instrumental to ESPN's inaugural Collegiate Esports Championship that was hosted in Houston earlier this year.

Work America Capital has supported sports technology in town before — including Houston-based Integrated Bionics, which has developed a GPS- and video-optimized sensor used by athletes around the world.

"As with any industry that takes off like a rocket, problems arise that must be solved through innovation," says Mark Toon, managing partner of Work America Capital, in the release. "Mainline is standardizing, organizing and optimizing the esports industry, paving the way for more players, more teams, more money and bigger, better tournaments."

Mainline is focused on expanding its services as esports continues to grow. According to the release, the total industry revenue for this year is expected to reach $1.1 billion worldwide, and viewership numbers have jumped from 335 million to 454 million in just two years.

"The strategic vision of Mainline puts them in the driver's seat with a consistent platform across amateur, collegiate and professional competitions," says Toon. "Given Mainline's partnerships and customers, they have paved a way to grow quickly across all sports and into other markets. We are excited to dedicate our time, resources and capital to the company."

Homecoming

The Cannon is finally getting to move its 150 startups and partners into its 120,000-square-foot campus in West Houston.

The original plan was to open in March, but construction, which began in April 2018, faced a series of setbacks due to weather. Current grand opening celebration plans are expected to be in September.

The flagship building is just the first step developing the campus, which is dubbed the Founders District.

"Our team has worked tirelessly to build this community over the past eighteen months, and we are incredibly proud to see our vision coming to life with the completion of this building," says The Cannon's CEO Lawson Gow in a news release. "The work isn't over though, and The Cannon will continue to grow our network of resources and locations to cater to the needs of Houston's growing entrepreneurial community." (Gow is the son of David Gow, owner of InnovationMap's parent company Gow Media.)

The building is currently 88 percent leased. Cannon Ventures, the company's investor group, will operate out of the new building, as will Capital Factory's Houston outpost. Austin-based Capital Factory, a statewide startup accelerator announced it would have its Houston operations at The Cannon in May. Since then, the company hired two Houston-based employees to run the programming.

According to the release, The Cannon will continue to grow its community relations for a "full suite" of partners. Houston-based investment fund Work America Capital, which led The Cannon's initial fundraising round, will also be joining The Cannon's community in the new building.

"It has been incredible to watch The Cannon's exceptional growth from inception two years ago to the vibrant community they've built today," says Mark Toon, managing partner of Work America Capital, in the release. "We can't wait to see the progress first-hand as The Cannon continues to establish themselves as a leader in building entrepreneurial communities."

The Cannon previously operated out of a 20,000-square-foot adjacent building called "The Waiting Room," which will be torn down and the space will be used as a part of the bigger Founders District plan.

The Cannon's new space will feature:

  • A 16-TV video wall
  • Outdoor courtyard
  • Movie theater
  • Snacks, coffee, and beer
  • Office needs, such as printers, scanners, and mail services
  • Showers
  • 24/7 accessibility
  • Professional and social events are organized on an ongoing basis for the community
  • Private event hosting for both members and non-members

This Houston sports tech entrepreneur wants more big wins for Houston

Featured Innovator

It took Stephane Smith and his brother, Yves, a few tries to get a revolutionary sports device that the market actually wanted. Now that they have, their Houston-based company, Integrated Bionics, has its Titan Sensor device being used worldwide — from Zimbabwe and Israel to Brazil and Mexico.

The Titan, which launched in 2017, syncs GPS with video and provides athletic metrics at an attainable price. Most of the company's customers are soccer teams primarily in the collegiate space — with some professional and even youth teams. Smith says the company has a firm footing within soccer because that's where this technology really started.

"People were doing GPS and sensing with soccer before we arrived. Soccer had this orientation from the get go," Smith tells InnovationMap. "There's a lot higher of awareness in soccer — but we think that awareness is going to grow across all sports as people realize how this data can be used without breaking the bank."

Smith spoke with InnovationMap about figuring out the Titan's technology, Houston's challenging venture capital environment, and why he hopes to be one of the city's big wins.

InnovationMap: Why did you want to start a company?

Stephane Smith: My background is in engineering. I worked at Intel for five years. I worked at silicon server processors — very deep into that, down to drawing wires of ultra miniature fabrication for electronics. It was an awesome experience. My group at Intel was actually an analogue group that was purchased by Intel. Analogue groups tend to be high risk in general. The company has to have a lot of trust in those people. My boss told me I had to go do something. At the time, I was married but didn't have any kids or own a home, so he was nudging me a little bit on a personal development side to go do my thing. This was in California, so everyone had startup fever. So, I quit my great job, and decided to do a startup.

IM: What brought you to Houston?

SS: We figured the cost of living was good, and it's where we grew up. We thought it'd be a good fit. My brother, Yves, and my co-founder, was doing a research project at the University of Texas at San Antonio.

IM: What was you and your brother’s first product?

SS: I'm a solutions guy and he had problems to solve. His problem at the time was sleep apnea monitoring and making sure patients are using the device. We made this really tiny device that could fit inside the retainer and it could communicate whether or not the person was wearing the mask. That was product No. 1. But then we found out no one wanted to buy it in the real world. It was kind of a reality check.

We pivoted. Inside the sensor, is something that could detect motion. We took the appliance and stuck it on a headband. I had one of my wife's friends do a header on a soccer ball. We had this nice video of someone heading a ball and the impact or reaction of the head movement. That was a couple years ago, and everyone was concerned about concussions. That was called Heads Up. We had some success and sales at the college level, but it still wasn't there yet.

IM: What was the issue with Heads Up?

SS: Concussions were kind of a taboo topic. The device was indicating something bad that happened. Something they did like on the report was how many steps they took. They were just looking at the performance metric. So, it was back to the drawing board. At the same time, we were trying to raise money in Houston, and it was a massive struggle. Houston's a hard place to raise money in general and especially in sports. We decided to just raise money from the customers. We wanted to make sure that people actually wanted the product. We doubled the price of the device and added a GPS sensor. We sold it to three teams before we even had it built yet. That became the Titan Sensor.

IM: But you did eventually find funding, right?

SS: We sort of stumbled upon Work America Capital. We weren't looking for it. Someone in my past life told me to check out this profile of Shane Hildreth. And I was like, hey it's a sports guy. I didn't think there was any of them in Houston. So, I contacted them. I feel like they got us — not just sports, but us — and had the same values of us. It was more than the money. We found a partner in them.

IM: Do you see venture in Houston changing?

SS: I don't know. I doubt it, at the moment. I think that what's missing is big wins. The analogy I like to use is I don't think that any city can build the Texas Medical Center. It's something built over generations. Silicon Valley has the same thing. You can just say, "Oh in five years, we'll make a task force and shabam, we're the next Silicon Valley." Every city's dream is that — that's why you hear Silicon Hill, Silicon Rock, Silicon Pond — you name it. But there's only one Silicon Valley and that's not going to change. There needs to be more wins and more leadership. We need more fish swimming in that direction to create momentum. Hopefully we become a win and can help build that momentum. Houston has all the ingredients.

IM: What’s next for Titan and other products?

SS: We're going to continue relentless innovation — doing things that no one is expecting and helping coaches with things not even on the radar. We'll going to be rolling out new capabilities and features that have traditionally been relegated to high-end systems or that haven't even existed before.

Generation Park lands new facility to scale xeno-organ production

Organ innovation

Maryland-based United Therapeutics Corp. has opened a new 77,448-square-foot facility to manufacture xeno-organs in Northeast Houston’s growing biotech hub, Generation Park.

The new Houston location is United Therapeutics’ third Designated Pathogen-Free (DPF) site, named for transplant pioneers Dr. Bartley P. Griffith and Dr. Robert A. Montgomery. The company says the new facility will enable it to scale commercial production of its xeno-organs once they receive regulatory approval.

An existing DPF facility in Virginia is supporting clinical trials for the xeno-organs, and a third site in Minnesota will also focus on commercialization with the Houston site, according to the company.

Xeno-organs are organs taken from a non-human animal source and transplanted, implanted or infused into a human recipient.

Currently, United Therapeutics is advancing clinical trials to support a Biologics License Application with the U.S. Food and Drug Administration for its investigational-stage xenotransplantation, UKidney, UThymoKidney and UHeart products. The products all involve working with the genes from humans and pigs.

In 2025, Chron.com reported the company was working to construct an estimated $96 million facility to breed genetically engineered animals. Head of investor relations at United Therapeutics Dewey Steadman told the Houston Business Journal in 2025 that the pigs’ DNA will be edited. In November 2024, a 53-year-old woman in Alabama received a transplanted kidney from UKidney that had 10 gene edits. She had the transplant removed in April 2025, after her body rejected it.

The Dr. Bartley P. Griffith and Dr. Robert A. Montgomery Xenograft Production Facility requires a “strictly controlled, biosecure barrier environment, including air filtration, filtered water, filtered feed supplies, and state-of-the-art decontamination entryways,” according to the company. Being pathogen-free means it includes calibrated air and water conduits to support the transplantability of xenograft products and to prevent contamination. For energy considerations, the building also features solar arrays.

“With our third xenograft production facility now open and clinical trials underway, United Therapeutics is moving closer to its goal of providing transplantable organs to the people who need them,” Martine Rothblatt, chairperson and CEO of United Therapeutics, said in a news release. “It is fitting that this facility is named for Dr. Griffith and Dr. Montgomery, whose first-in-human surgeries turned xenotransplantation from a theoretical possibility into a clinical reality.”

The facility, which wrapped construction in August, is located at 11848 Common Dock Dr. in Generation Park, which will house manufacturing sites for pharmaceutical heavyweights Bristol Myers Squibb and Eli Lilly. Last fall, Eli Lilly tapped Generation Park for its $6.5 billion manufacturing plant, and Bristol Myers Squibb made a $2.3 billion investment in August to bring its state-of-the-art site to the master-planned commercial district.

Elon Musk's SpaceX reports profit as AI and satellite businesses booms

Booming Business

SpaceX reported a bigger quarterly profit than expected on Tuesday, October 20, as its satellite communications and artificial intelligence businesses boomed.

The company, run by Elon Musk, posted a profit for the three months through September 2026 of $4.4 billion, or 35 cents per share, reversing a year-ago loss and easily topping Wall Street's expectations. Revenue soared to $14.6 billion, up 161%.

On a conference call with analysts, Musk suggested a merger with his electric car company Tesla might be in the works, something that has been rumored for months. He said both companies formed “special committees” of independent directors to discuss the issue, though he played down the chances of an imminent deal.

“Some people out there assume that a SpaceX and Tesla merger is a certainty,” he said. “I think that would be overstating it.”

The AI business became SpaceX's largest by revenue in the third quarter, although the Starlink satellite service remains the biggest profit generator.

“They beat across all metrics and the Starlink business looks to be accelerating,” said Dan Ives, an analyst at Yorkville Ives. “This is just what (Wall) Street wanted.”

The stock rose 7.5% in after-hours trading.

Musk also told analysts that for next month's launch of its Starship rocket, SpaceX will attempt to grab both the booster and ship with mechanical arms upon return to base, a key step toward demonstrating it can reuse the massive spacecraft.

“The only way that we can extend consciousness beyond Earth on a sustained basis is with a fully reusable orbital launch vehicle,” Musk said, calling the attempt, if successful, “a massive technology milestone.”

SpaceX hopes to get Starship on a regular launch pattern in preparation for NASA's upcoming lunar missions.

The company already has huge contracts with the federal government, and House Democrats have called for investigations into those contracts and Musk’s work with the Department of Government Efficiency. Musk has spent $276 million since July in support of Republican candidates.

In a filing for its initial public offering in June, SpaceX warned that a change in control of Congress could have a “material and adverse impact on our growth and competitive position.”

Musk recently drew criticism from politicians in Washington after speeds for a military version of SpaceX's satellite communications service were slowed for Ukraine following President Donald Trump's deal to get more diesel oil from Russia amid a push to end the war. The Wall Street Journal reported Tuesday that it was Musk who ordered the slowdown, impeding Ukraine’s use of drones along the front. SpaceX did not immediately respond to an Associated Press request for comment on the Journal story.

Both Trump and Musk have denied responsibility for the slowdown.

As midterm elections near, Musk on Monday promised to give one share of SpaceX to “every kid in America” next year, though he provided no details on how the distribution would be carried out. With communities nationwide protesting the construction of large data centers and concerns about AI safety, AI companies are trying to build goodwill. Anthropic pledged to commit 5% of its shares to a new “public benefit” fund.

SpaceX shares have been under pressure over concerns that the company was spending too much on major projects to compete with rivals such as Anthropic. The company said capital expenditures totaled $19.6 billion last quarter, nearly triple the figure from a year earlier, and it forecast spending would grow to $35 billion to $40 billion in the current quarter.

Shares of SpaceX closed Tuesday at $147.79, down from a peak near $201 after its IPO, which made Musk the world’s first trillionaire at the time. But the share prices for SpaceX and Tesla have since dropped, reducing his net worth to $925 billion, according to Forbes magazine.

Tesla reports third-quarter financial results Wednesday. Last week, Tesla unveiled a new Roadster sports car that in some versions may include thrusters allowing it to briefly fly using SpaceX technology — though experts say anything usable for drivers is a long shot.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.
