While Chris Buckner has found the isolation aspect of the pandemic challenging, he shares on this week's episode of the Houston Innovators Podcast that it's actually been an extremely exciting time for his esports tournament software startup, Mainline. This year, Mainline is poised to onboard over 100 schools to their system, and, while most of those schools were lined up before the pandemic, the process has been sped up.

"Everyone is looking for how to get sports, or esports, in front of people because everyone is just missing [sports] so much," Buckner says. "We've been very fortunate to work in the industry we do."

On campuses this past spring, basketball was cut short, baseball was canceled, and football's status is currently unknown. Colleges are looking for a way to connect with and engage students, Buckner says. And, Mainline has even been able to attract interest on the professional level. Read more and strea

Austin Hill and Brad Jenkins, co-founders of Seed Round Capital

Brad Jenkins and Austin Hill wanted to create a firm that prioritized funding for growing tech startups in Houston, so they teamed up to launch Seed Round Capital, an investment and advisory firm based in Houston and for Houston-based startups. Rather than an accelerator model, the new firm will focus on long-term support for its portfolio companies.

"Our program helps startup founders fund and scale their businesses with management guidance from seasoned entrepreneurs. In addition, founders receive training on proven business methods specially formulated by Seed Round Capital, and access to funding," Hill says in a statement to InnovationMap.

Startups can apply online to be selected to receive mentoring from Jenkins, Hill, and a network of experts involved in — or previously involved in — Entrepreneurs' Organization (EO), a local group of business leaders. Once selected, Seed Round's startups will have access to office space at The Cannon. Read more.

Exclusive: 2 serial entrepreneurs launch Houston startup incubator

funding focused

Two Houstonians with years of entrepreneurial and investing experience are starting a firm focused on advising and growing local technology startups.

Brad Jenkins and Austin Hill have announced the launch of Seed Round Capital, an investment and advisory firm based in Houston and for Houston-based startups. Rather than an accelerator model, the new firm will focus on long-term support for its portfolio companies.

"Our program helps startup founders fund and scale their businesses with management guidance from seasoned entrepreneurs. In addition, founders receive training on proven business methods specially formulated by Seed Round Capital, and access to funding," Hill says in a statement to InnovationMap.

Startups can apply online to be selected to receive mentoring from Jenkins, Hill, and a network of experts involved in — or previously involved in — Entrepreneurs' Organization (EO), a local group of business leaders. Once selected, Seed Round's startups will have access to office space at The Cannon.

"Because we recognize that every new business is unique in its journey, we are able to customize mentoring to suit each startup. Our expertise helps startups reduce risk, secure funding and grow faster than if they were doing this on their own," Jenkins says.

Jenkins has 25 years of software and technology startup experience and has served on the Houston board of EO. A Texas A&M University alumnus, he has a background in marketing and computer science. Hill's specialty includes distribution, contracting, real estate, and consumer-packaged goods. A University of Texas and West Point graduate, he won Rice University's Veterans Business Battle competition and organizes the EO's accelerator program.

Houston researchers develop dissolvable implant for targeted cancer drug delivery

cancer research

Researchers at Houston Methodist have developed a biodegradable implant that can be used to safely and consistently deliver drug treatments to tumors and then dissolve without the need for further surgery.

The implant is only the size of a grain of rice, but its potential is staggering. The biodegradable nanofibrous drug-eluting seed (b-NDES) works as a reservoir parked inside a soft tumor, where it can slowly release immune-stimulating drugs over time. This overcomes a consistent problem with drugs such as immune checkpoint inhibitors. Normal systemic administration sees comparatively little of the drug making its way to the tumor, with most of it circulating throughout the body. The b-NDES is like deploying a small guerrilla fighting force embedded in enemy territory, doing maximum damage to the entrenched tumor.

"To improve cancer treatment, we're trying to start a fire inside the tumor itself," Corrine Chua, associate professor in the Center for BioNanoengineering at Houston Methodist Research Institute, said in a news release. "By activating immune cells directly within the tumor microenvironment, those cells can then travel throughout the body and seek out cancer wherever it exists. The b-NDES platform was developed to help keep therapeutic drugs concentrated inside tumors while minimizing exposure to healthy tissues.”

Chua co-led the study with Alessandro Grattoni, chair and director of the Center for BioNanoengineering at Houston Methodist Research Institute.

The study included support from the Nancy Owens Breast Cancer Foundation and the National Institutes of Health/National Cancer Institute.

Chau and Grattoni used preclinical models of triple-negative breast cancer, an aggressive form of cancer that is estrogen receptor-negative, progesterone receptor-negative and HER2-negative. Because of the receptor negativity, some popular treatments like tamoxifen and trastuzumab are ineffective. Chemotherapy has been shown to be the best course of action.

The b-NDES implant is deployed alongside radiation drugs. It keeps the drugs focused on the tumor, reducing the amount of harmful side effects typically seen when drugs are circulated more widely in the body. In 60 percent of the models, tumors were eliminated and did not cause side effects beyond the tumor site. Once the drugs have been deployed, the implant breaks down naturally.

While promising, more research will have to be done to expand use to other tumor types.

"Although the study focused on triple-negative breast cancer models, the approach could have broader applications for solid tumors," Grattoni added in the release. "It could potentially be used in cancers where there is a tumor lesion accessible for placement, including pancreatic or lung cancers."

New Houston platform Same Day Reels launches for on-demand content creation

In The Moment

If an event doesn't happen on Instagram, did it even really happen? In today's social media-driven age of branding and audience engagement, the answer increasingly is no.

Houston entrepreneur Karen De Amat is looking to fill the online content creation needs of companies with her new venture, Same Day Reels, which launched in early August. It will serve as a platform to connect companies and brands with talent that can help turn an event into a viral moment as it is happening.

"Events move quickly, and social media moves even faster,” said De Amat. “Same Day Reels was built to help brands capture the moment while it still matters. We are creating a more efficient way for businesses and creators to work together. Brands need content faster, and creators need more opportunities to turn their talent into real work. Same Day Reels brings those needs together.”

The company is focused on adding livestreams and concurrent short video content to "activations, launches, fundraisers, grand openings, conferences, hospitality experiences, and private celebrations." Such content can significantly increase the visibility of a product or brand according to digital marketing brands like Wyzowl, whose data found 63 percent of people in 2026 prefer to learn about new products via short video.

Packages offered by Same Day Reels will include filming, editing, and publishing content within hours of the targeted event.

De Amat says that her content creation platform will be a way to preserve the excitement of events and launches by enshrining them with immediate social media-driven memories.

“Event content is no longer just something you post after the fact,” De Amat said. “It is part of how people experience, remember and share the moment.”

Previously, De Amat is also the founder and CEO of Social Behavior, an influencer marketing company she launched from her home in 2014. It quickly garnered an array of clients and thrust De Amat into the spotlight, including numerous appearances on Fox 26's The Isiah Factor. Influencer Marketing Hub named her one of the top CEOs of influencer marketing companies in Houston in 2025.
