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."

Houston Outlaws esports team sold to local real estate investor for $40 million

Game on

Houston real estate investor Lee Zieben has agreed to terms with Immortals Gaming Club to purchase the Houston Outlaws for a total deal value of $40 million, sources familiar with the deal told ESPN.

According to an original ESPN report, the deal has not been executed but is expected to close in late August, with Zieben currently having a binding letter of intent with Immortals for the purchase, according to sources. Paperwork submission to and approval of the Overwatch League is pending, league sources said.

If completed as expected, Zieben will pay $30 million in cash and securities and assume the $10 million debt in remaining payments to the Overwatch League for the Houston Outlaws franchise slot, sources said. Immortals declined to comment. Lee Zieben's office and the Overwatch League did not respond to a request for comment.

Immortals will sell the team after they acquired Infinite Esports & Entertainment, the parent of OpTic Gaming and the Outlaws, in June.

Immortals will retain their ownership of OpTic, splitting that team and the Outlaws for the first time. In June, Immortals completed a deal with Activision Blizzard to enter the franchised Call of Duty League that is set to launch in 2020.

The deal for Infinite saw Immortals guarantee payments of $35 million to $45 million worth of cash and equity share to Texas Esports — backed by Texas Rangers owners Neil Leibman and Ray Davis and Houston Astros minority owner John Havens — and Aurelius Esports, led by former Infinite president Chris Chaney. Immortals also assumed debts Infinite owed, including the Outlaws' Overwatch League payments and OpTic's remaining franchise fees to the League of Legends Championship Series, totaling the deal to an enterprise value of over $100 million.

With the acquisition of Infinite, the Overwatch League required Immortals to sell the Outlaws to a third party as quickly as possible, due to Immortals' ownership of the fellow league team, the Los Angeles Valiant. No team is allowed to own equity in two different teams in the Overwatch League.

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."

UH student earns prestigious award for cancer vaccine research

up-and-comer

Cole Woody, a biology major in the College of Natural Sciences and Mathematics at the University of Houston, has been awarded a Barry Goldwater Scholarship, becoming the first sophomore in UH history to earn the prestigious prize for research in natural sciences, mathematics and engineering.

Woody was recognized for his research on developing potential cancer vaccines through chimeric RNAs. The work specifically investigates how a vaccine can more aggressively target cancers.

Woody developed the MHCole Pipeline, a bioinformatic tool that predicts peptide-HLA binding affinities with nearly 100 percent improvement in data processing efficiency. The MHCole Pipeline aims to find cancer-specific targets and develop personalized vaccines. Woody is also a junior research associate at the UH Sequencing Core and works in Dr. Steven Hsesheng Lin’s lab at MD Anderson Cancer Center.

“Cole’s work ethic and dedication are unmatched,” Preethi Gunaratne, director of the UH Sequencing Core and professor of Biology & Biochemistry at NSM, said in a news release. “He consistently worked 60 to 70 hours a week, committing himself to learning new techniques and coding the MHCole pipeline.”

Woody plans to earn his MD-PhD and has been accepted into the Harvard/MIT MD-PhD Early Access to Research Training (HEART) program. According to UH, recipients of the Goldwater Scholarship often go on to win various nationally prestigious awards.

"Cole’s ability to independently design and implement such a transformative tool at such an early stage in his career demonstrates his exceptional technical acumen and creative problem-solving skills, which should go a long way towards a promising career in immuno-oncology,” Gunaratne added in the release.

Houston founder on shaping the future of medicine through biotechnology and resilience

Guest Column

Living with chronic disease has shaped my life in profound ways. My journey began in 5th grade when I was diagnosed with Scheuermann’s disease, a degenerative disc condition that kept me sidelined for an entire year. Later, I was diagnosed with hereditary neuropathy with liability to pressure palsies (HNPP), a condition that significantly impacts nerve recovery. These experiences didn’t just challenge me physically, they reshaped my perspective on healthcare — and ultimately set me on my path to entrepreneurship. What started as personal health struggles evolved into a mission to transform patient care through innovative biotechnology.

A defining part of living with these conditions was the diagnostic process. I underwent nerve tests that involved electrical shocks to my hands and arms — without anesthesia — to measure nerve activity. The pain was intense, and each test left me thinking: There has to be a better way. Even in those difficult moments, I found myself thinking about how to improve the tools and processes used in healthcare.

HNPP, in particular, has been a frustrating condition. For most people, sleeping on an arm might cause temporary numbness that disappears in an hour. For me, that same numbness can last six months. Even more debilitating is the loss of strength and fine motor skills. Living with this reality forced me to take an active role in understanding my health and seeking solutions, a mindset that would later shape my approach to leadership.

Growing up in Houston, I was surrounded by innovation. My grandfather, a pioneering urologist, was among the first to introduce kidney dialysis in the city in the 1950s. His dedication to advancing patient care initially inspired me to pursue medicine. Though my path eventually led me to healthcare administration and eventually biotech, his influence instilled in me a lifelong commitment to medicine and making a difference.

Houston’s thriving medical and entrepreneurial ecosystems played a critical role in my journey. The city’s culture of innovation and collaboration provided opportunities to explore solutions to unmet medical needs. When I transitioned from healthcare administration to founding biotech companies, I drew on the same resilience I had developed while managing my own health challenges.

My experience with chronic disease also shaped my leadership philosophy. Rather than accepting diagnoses passively, I took a proactive approach questioning assumptions, collaborating with experts, and seeking new solutions. These same principles now guide decision-making at FibroBiologics, where we are committed to developing groundbreaking therapies that go beyond symptom management to address the root causes of disease.

The resilience I built through my health struggles has been invaluable in navigating business challenges. While my early career in healthcare administration provided industry insights, launching and leading companies required the same determination I had relied on in my personal health journey.

I believe the future of healthcare lies in curative treatments, not just symptom management. Fibroblast cells hold the promise of engaging the body’s own healing processes — the most powerful cure for chronic diseases. Cell therapy represents both a scientific breakthrough and a significant business opportunity, one that has the potential to improve patient outcomes while reducing long-term healthcare costs.

Innovation in medicine isn’t just about technology; it’s about reimagining what’s possible. The future of healthcare is being written today. At FibroBiologics, our mission is driven by more than just financial success. We are focused on making a meaningful impact on patients’ lives, and this purpose-driven approach helps attract talent, engage stakeholders, and differentiate in the marketplace. Aligning business goals with patient needs isn’t just the right thing to do, it’s a powerful model for sustainable growth and lasting innovation in biotech.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
