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."

Rice lands $15M U.S. Army award to launch next-gen wireless research center

defense funding

The U.S. Army Research Office has awarded Rice University $15 million to establish a new center for next-generation sensing and communications.

The five-year research center—dubbed the Center for Large Aperture Secure Sensing, Imaging and Communications (CLASSIC)—will unite researchers from universities and national laboratories to develop advanced antenna technologies for future wireless systems. Edward Knightly, the Sheafor-Lindsay Professor of Electrical and Computer Engineering at Rice, will lead the center that “combines expertise in wireless networking, antennas, radar, artificial intelligence, circuits and physics to address growing demands on wireless systems,” according to Rice.

“The challenges we’re tackling require advances that span physics, hardware, communications and computing," Knightly said in a news release. “By combining those strengths in a single center, we can accelerate the development and demonstration of technologies that would not be possible through individual efforts alone.”

Joining Knightly will be Ashutosh Sabharwal of Rice, Sensen Li of the University of Texas at Austin, Hou-Tong Chen of Los Alamos National Laboratory, Danijela Cabric of UCLA, Josep M. Jornet and Tommaso Melodia of Northeastern University, Daniel M. Mittleman of Brown University, and Willie Padilla of Duke University.

Industry partners include Booz Allen Hamilton, Intel, Keysight, Lockheed Martin, MITRE, Northrop Grumman, Qualcomm and Raytheon.

CLASSIC researchers will investigate how large-scale antenna arrays (ELSAAs) can expand the capabilities of wireless systems where technology is limited.

ELSAAs use thousands of coordinated antenna elements to direct radio waves. Researchers aim to develop ways to use the technology to help maintain steady communication when signals are blocked or disrupted and to detect and generate detailed images of concealed objects.

Along with ELSAAs, the center will work to develop sensing techniques for threat detection, study wireless jamming and build resilient high-speed wireless networks. Researchers will ultimately validate the technology in labs and via drone-based field trials.

CLASSIC will also work on developing an AI-driven modeling framework that will simulate complex electromagnetic environments in real time.

“This award demonstrates Rice’s leadership in tackling complex national research challenges through collaboration across disciplines and institutions,” David Sholl, executive vice president for research at Rice, added in the release.

UH scores $18M NIH grant for chronic disease research

research funding

The University of Houston has received a coveted $18.8 million grant from the National Institutes of Health to launch a program to address the root causes of chronic disease.

Only 22 institutions nationwide receive this NIH award, and the 5-year process aligns with the newly established UH Health’s mission to expand healthcare innovations in Texas and beyond. The initiative will be housed in the UH Population Health department.

"This generous funding allows us to directly confront the root causes of chronic illness that place a heavy burden on so many families," Dr. Jonathan McCullers, vice president for health affairs at UH, said in a news release. "With the recent launch of UH Health, we have an unprecedented opportunity to translate scientific discovery into healthier outcomes for our communities by bringing together experts from across the university to improve health where it matters most.”

Through the program, UH researchers from different areas of expertise will work together to address the challenges of chronic illness by looking at biological, social and behavioral factors.

According to the university, chronic diseases like heart disease, diabetes, strokes and others are the leading cause of illness, disability and death in the U.S. They account for 90 percent of the nation’s $5.3 trillion in annual healthcare spending.

Bettina Beech, chief of population health and translational science at UH, serves as principal investigator for the program.

“Chronic disease management largely happens during the 8,700 hours each year that people are not visiting their healthcare provider,” Beech added in the news release. “While healthcare is indispensable, it only accounts for 20 percent of how health is created — genetics accounts for another 10 percent, and the other 70 percent is determined by behavior, social conditions and environment.”

With the funds from the grant, UH will also be able to expand research infrastructure, add to community partnerships, support complementary research, and invest in early-career investigators, according to the news release. UH also aims to develop solutions that could help ease the economic burden of chronic disease.
