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."

Houston cleantech, space startups named to World Economic Forum cohort

top honor

Two Houston-based startups have been selected to join the World Economic Forum's Technology Pioneers community.

The two-year program aims to help mission-driven, early-stage start-ups scale their innovations through multi-stakeholder initiatives, co-creating partnerships and other gatherings for community members. One-hundred startups are selected each year from around the globe, this year hailing from 23 countries and working in AI, energy, space, biotech markets and more.

Cleantech startup Vaulted Deep was one of 11 energy and climate companies to be named to the cohort. Julia Reichelstein and Omar Abou-Sayed founded the company in 2023. Its technology injects excess organic waste underground to remove carbon dioxide from the atmosphere.

Last year, Vaulted Deep inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

The startup has earned several accolades in recent years, including a No. 3 spot on Fast Company’s list of the World’s Most Innovative Companies of 2026. It was also recently named to market intelligence and advisory firm Cleantech Group's annual Global Cleantech 100 list for a second year in a row.

"Waste management is one of the world's great invisible infrastructure systems ... The need for new infrastructure is growing as disposal challenges become more complex and regulations evolve. Vaulted is building the first new disposal pathway for organic waste in decades by putting it deep underground, permanently," the company shared in a LinkedIn post. "This year, we're joining the World Economic Forum's 2026 Tech Pioneers alongside innovators working on the many interconnected challenges shaping our future."

Houston-based Venus Aerospace was also selected to join the cohort, along with six other spacetech companies. The company was founded in 2020 by Sassie and Andrew Duggleby.

The startup specializes in next-generation rocket engine propulsion as a cleaner alternative to traditional combustion engines. The company's rotating detonation rocket engine (RDRE) burns fuel more efficiently and completed a successful high-thrust test flight last year. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

"Frontier technologies matter most when they expand what people, industries, and nations can do," Sassie Duggleby, co-founder and CEO of Venus, said in a news release. "For Venus, RDRE does not just represent a more efficient engine. It is a foundation for faster movement, more capable space systems, and new forms of connectivity across the planet. Being named a Technology Pioneer validates the potential of this technology to help shape a future where distance is less limiting."

Houston Methodist receives record $110M gift, names future tower

historic gift

Houston Methodist has received the largest gift in the health system's history to establish new funds for neurological, neuroscience, and women’s health research and treatment.

The $110 million gift comes from Houston-based The Brockman Medical Research Foundation, which supports education and research in the science, medicine and healthcare fields. In response, Houston Methodist announced that it will name its forthcoming 26-story hospital facility the Brockman Centennial Tower.

The tower’s entrance will be named the Anna Margaret Bellows Centennial Hall to honor Anna Margaret Bellows, a young camper who died during the Camp Mystic flooding last summer.

“This extraordinary gift accelerates discovery and transforms how care is delivered,” Dr. Marc Boom, president and CEO of Houston Methodist, said in a news release. “We are grateful to The Brockman Medical Research Foundation for its incredible generosity and vision that will help change the lives of generations of patients. Naming Centennial Tower in recognition of this gift reflects the scale of this commitment and its impact on the future of neuroscience, neurological care and women’s health.”

The gift will be divided into two parts:

  • $100 million will go toward creating an innovation fund within the Houston Methodist Academic Institute and the Houston Methodist Neurological Institute
  • $10 million will be devoted to Houston Methodist's Department of Obstetrics and Gynecology

“This tremendous gift will accelerate translational research that broadens our understanding of neurological and other diseases,” Dr. Jenny Chang, president and CEO of the Houston Methodist Academic Institute, added in the release. “It will allow us to leverage state-of-the-art platforms to detect, diagnose and deliver therapeutics, keeping patient care at the center of our mission.”

The Brockman Centennial Tower is expected to open next year in the Texas Medical Center. Spanning more than 1 million square feet, it will house 400 patient beds, an expanded emergency department, new operating rooms and a rooftop garden. It will be connected to Houston Methodist's flagship Paula and Joseph C. “Rusty” Walter III Tower, which opened in 2018. The Centennial Tower was estimated to cost $1.4 billion when announced in 2022.

In addition to the news of the Brockman gift, Houston Methodist also announced this month that it has launched the Houston Methodist Center for Cell and Gene Therapy and tapped an internationally recognized scientist as its leader.

The new center is focused on discovering and developing innovative and cost-effective therapies for a variety of congenital and acquired diseases, including cancer, HIV and cardiovascular disease.

Dr. Malcolm Brenner has been named as the center's inaugural leader and will assume the role starting in October. He will work alongside scientists and support staff from Baylor College of Medicine and Texas Children's Hospital.

Brenner is a professor of pediatrics, medicine, molecular and human genetics and translational biology at Baylor College of Medicine. He is known for making early advances in using bone marrow transplantation as a form of cell therapy and in engineered immune-cell treatments for cancer and infections, according to a release from Houston Methodist.

“Malcolm Brenner is a pioneer in the field of cell and gene therapy and is uniquely qualified to lead Houston Methodist’s research efforts in this field,” Chang added. “His vision and leadership will play a pivotal role in advancing our work in this space.”
