Kim Raath is pretty proud of her company right about now. Not only is she proud that her startup, Topl, a blockchain network with applications across industries, closed a 20 percent oversubscribed $700,000 seed round, but because she did it in a way that was directly in line with her company's values.

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

Houston-based Topl was created by a few Rice University graduates and doctoral students — Raath, Chief Technology Officer James Aman, and CEO Chris Georgen. The founders wanted to create a way to track impact in various industries, such as carbon footprints in oil and gas or fair wages for farmers in agriculture.

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.

"It's a validation time for us," Raath tells InnovationMap. "With two platforms already live and collecting transaction fees, we are now at a point where there are actual blockchain transactions happening on our network."

The fact that Topl's technology is already up and running is rare. For this reason, Raath says she has to focus a lot on educating investors, clients, and the rest of the community — something that's really important to her.

"In the blockchain space, there are not a lot of real applications live anywhere," Raath says. "A lot of people are selling ideas that can be built on blockchains, but have not executed yet."

Topl partnered with European NGO Fairfood to create an agricultural blockchain platform that currently is live. Shoppers in the Netherlands can buy a pack of nutmeg and track the product's progress from the farmer who grew and sold the spice. The other already launched platform is focused on sustainability. Topl worked with the Texas Coastal Exchange to create a carbon credit marketplace that can sell carbon offsets generated through the natural carbon sequestration activities of land the organization holds along the Texas coast.

"For us this round is taking these four spaces and validating ourselves, proving out volume, the blockchain's ability, and then, the big thing is, to build out our next version of our blockchain," Raath says.

Raath says the fundraising round was different from what she expected, but she's excited about her investors. Seventy percent of the round was raised by Houstonians, and 40 percent of the investors were women, she says. Topl also had investor interest across industries and backgrounds — from Rice University professors to former banking execs.

The round doesn't technically have a lead investor, but Samantha Lewis, director at the GOOSE Society of Texas, led a syndicate of investors that made up more than 40 percent of Topl's round. Lewis says the round was too early stage for something GOOSE investors would typically contribute to, but she believes in the company so much that she worked nights and weekends to accomplish some of the things a lead investor would do during a raise.

"Since this was their first big round that they raised, I stepped in to help advise them — thinking about the terms, strategic investors, how to pitch to different people, if they needed to oversubscribe, and little details like that," Lewis says. "Through working with them in this way, I was doing diligence with them, and I got really excited about it."

Lewis, who volunteers a lot within the Rice network, met Raath through Georgen and the two hit it off. Lewis was then able to bring in investors from her network to contribute under her syndicate.

This passionate group of value-add investors who are personally committed to the company is what makes this seed round different for Raath. Their commitment is encouraging to her.

"I 100 percent believe that the investors in this round will not allow Topl to fail," Raath says.

With the money, Topl will be able to grow its platforms, provide better product features, and increase marketing efforts. Topl's customers are drawn to the technology because of the business efficiency the blockchain adds to their supply chain, but they are also excited about how having this technology differentiates them from their competition. Raath says she's interested in growing Topl's ability to do joint marketing campaigns with their customers.

This type of promotion leads to a growing clientbase, and Raath says she sees an overwhelming interest from potential clients. Not only is Topl creating a series of platforms in various industries, but the company itself is connecting other companies through their clients.

"Topl is not just a technology," Raath says, "it's an ecosystem."

Italian aerospace company sets up first U.S. office at Houston Spaceport

welcome to houston

Como, Italy-based aerospace company Involve Space recently made the Houston Spaceport the site of its first U.S. office.

Involve Space develops high-altitude balloon platforms for Earth observation, scientific research and hardware testing. The balloons carry instruments into the stratosphere (a layer of the upper atmosphere) to collect images and data, conduct experiments and test technology.

The company plans to launch its first commercial missions from Houston by the end of this year, according to a news release.

“Houston is the global center of aerospace, and our presence at Houston Spaceport strengthens our international growth trajectory,” Jonathan Polotto, founder and CEO of Involve Space, said in the release.

Founded in 2021, Involve Space incorporates aerospace hardware, AI and geospatial tools into its offerings. Its proprietary CLEAR platform uses conversational AI to help customers interpret data and support decision-making.

Located at Ellington Airport, the Houston Spaceport provides a base for Involve Space’s North American operations, including business development and partnerships with aerospace companies and researchers.

Other tenants at the Houston Spaceport include NASA, Axiom Space, Venus Aerospace and Intuitive Machines.

Involve Space’s relationship with the Houston Spaceport began in January 2025, when it conducted its first U.S. pilot launch. During the five-hour mission, the balloon reached an altitude of about 85,000 feet and traveled about 250 miles across Texas.

One of Involve Space’s first U.S. customers is Houston-based Rhodium Scientific, a space biotech company. Polotto and Rhodium Scientific founder and CEO Olivia Gamez Holzhaus signed a deal to conduct biotech experiments aboard Involve Space’s stratospheric balloon platforms before planned missions to orbit.

“The presence of innovative platforms like those developed by Involve strengthens the Spaceport’s role as a site for testing, validating, and deploying advanced technologies between aeronautics and space,” Jim Szczesniak, director of aviation for Houston Airports, added in the release.

UH lands $3M grant to expand opioid overdose training

Overdose Response

The University of Houston has received a $3 million federal grant to expand its potentially life-saving overdose response training program.

The grant will support the Houston Health Department’s FRONTLINES program that trains first responders in Harris and Fort Bend counties to recognize opioid overdoses and administer the drug naloxone, which can counter the effects of an opioid overdose. The four-year grant comes from the Substance Abuse and Mental Health Services Administration within the Department of Health and Human Services, and it builds on eight years of work at UH, according to a release from the university.

As part of the expansion, UH medical, social work and psychology students will now also be able to take part in FRONTLINES’ overdose-response training. Some of the students will also be selected to help train community members, ultimately passing along the life-saving skills throughout Houston.

FRONTLINES is a collaboration with the City of Houston, the Fertitta College of Medicine, Baylor College of Medicine and the Houston Recovery Center. It was co-founded by Dr. James Bray, chair of the Department of Behavioral and Social Sciences at the University of Houston’s Tilman J. Fertitta Family College of Medicine, in 2018.

“When someone experiencing an opioid overdose is reached in time, naloxone can save their life,” Bray said in a news release. “We’ve seen the impact this training can have in Houston, and now we have an opportunity to extend that reach across Harris and Fort Bend counties, putting lifesaving knowledge and tools into the hands of more first responders.”

In 2024, around 450 residents of Harris County died from opioid overdoses, according to a Texas Department of State Health Services report. The report found that fentanyl was involved in about three-quarters of the deaths.

In 2025, UH also received a $2.6 million gift from the estate of Dr. William A. Gibson to expand its opioid research and develop a vaccine to help block fentanyl's effectiveness in entering the brain. The vaccine research is part of the Michael C. Gibson Addiction Research Program led by UH professor of psychology Therese Kosten and founding member of the UH Drug Discovery Institute Colin Haile.

Texas public libraries drive billions in economic impact, report finds

Beyond the Stacks

A new statewide study examining the economic impacts of public libraries has revealed they have generated over $3.8 billion in value to local communities — a return of $4.74 for every $1 invested.

The report, "Beyond the Stacks: Measuring the Economic and Community Value of Texas Public Libraries" was conducted by third-party consultancy JBK Economics Group in partnership with the Texas Library Association. About 300 of the total 513 public libraries in Texas participated in a survey for the report.

A major finding from the survey revealed that public libraries create billions in economic value for the communities they serve at a fraction of what it costs to pay employee wages and benefits, operating expenditures, and capital expenditures. About 11,200 jobs were directly and indirectly supported by public libraries, the report found.

The report found its $4.74 to $1 ratio by adding up the total value of the services provided by these institutions (an estimated $2.48 billion), and comparing it to total expenditures ($808.6 million).

"Public libraries had about the same economic footprint as the Texas motion picture and sound recording industry ($2.9 billion in Gross Domestic Product in 2024) or the Texas paper manufacturing industry ($4.0 billion in Gross Domestic Product in 2024)," the report said.

Many Houstonians are already familiar with Houston Public Library's expansive catalog and programming, but there are many more services the library provides that might fly under the radar. A few examples include access to subscription-based research databases and news outlets, and the Library of Things, a collection of cookware and bake ware, musical instruments, craft kits, and other tools or activity materials that are available for cardholders to borrow. Individual branches also provide free Wi-Fi, computer access, and meeting spaces.

Houston-area residents also have access to services at several other local libraries depending on their address, such as the Harris County Public Library, Montgomery County Memorial Library System, or Fort Bend County Libraries, just to name a few.

These are additional services and partnerships that Texas public libraries commonly provide, per the survey results:

  • 93 percent provide voter registration and/or serve as voting locations
  • 84 percent provide partnerships with local social services agencies
  • 82 percent provide job application assistance
  • 68 percent facilitate applications for government benefits
  • 38 percent provide on-site social services
  • 30 percent provide telehealth rooms and/or resources
"Public libraries are practical, welcoming and rooted in the communities they serve — they are unmistakably Texan," said Texas Library Association executive director Shirley Robinson in a press release. "This study puts a dollar value on the opportunities libraries create every day. Whether someone visits a library to apply for a job, access the internet, learn a new skill or simply find a new favorite book, those services create real value for Texans and their communities."
