Fueled by fresh funding in the bank, a medical device startup has announced upcoming trials.

VenoStent, Inc., a company developing an innovative tool to improve outcomes for hemodialysis patients, has closed $16 million in a series A round of financing. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round.

The company also announced it received Investigational Device Exemption from the FDA for its United States clinical trial, SAVE-FistulaS.

“Our mission at VenoStent is to improve the quality and length of life of dialysis patients. On the heels of our very promising results in several preclinical studies and a 20-patient feasibility study that led to our Breakthrough Designation last year, this recent IDE approval is perhaps our biggest milestone to date," Tim Boire, CEO of VenoStent, says in a news release. "We now enter an exciting new epoch in our company’s development that we believe will ultimately result in FDA Approval and vastly improve the quality and length of life for patients."

VenoStent's series A will fund the trial, expand manufacturing capabilities, and more. The company is targeting the more than 800,000 people in the U.S. with end-stage renal disease. Currently, more than half of the surgeries performed to initiate hemodialysis fail within a year. VenoStent's novel therapeutic medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

“This trial is designed to provide the highest level of clinical evidence. We’re excited to be in this position to treat the first patients in the United States with this technology, and demonstrate the safety and efficacy of our device,” continues Boire in the release.

Per the release, the company is aiming for FDA Approval and be the first-to-market device to improve hemodialysis access surgery.

“We’re extremely pleased to be partnering with VenoStent on this critical mission. This company and technology are poised for commercial success to address a critical, unmet need,” says Bob Crutchfield, operating partner at Good Growth Capital, in the release.

The TMC Venture Fund also contributed to the series A investment round, along with SNR, Baylor Angel Network / Affinity Fund, Creative Ventures, Cowtown Angels, Alumni Ventures, and other notable angel investors. Past investors in VenoStent include KidneyX, National Science Foundation, National Institute of Health, Y Combinator, Health Wildcatters, and the Texas Halo Fund.

“VenoStent’s data and traction to date is impressive and gives us a lot of confidence in their continued success. We look forward to helping them get this Breakthrough product to market and help patients that are in dire need of this innovative technology,” says Joel Whitley, partner at IAG Capital Partners, in the release.

Houston space tech companies land $25 million from Texas commission

Out Of This World

Two Houston aerospace companies have collectively received $25 million in grants from the Texas Space Commission.

Starlab Space picked up a $15 million grant, and Intuitive Machines gained a $10 million grant, according to a Space Commission news release.

Starlab Space says the money will help it develop the Systems Integration Lab in Webster, which will feature two components — the main lab and a software verification facility. The integration lab will aid creation of Starlab’s commercial space station.

“To ensure the success of our future space missions, we are starting with state-of-the-art testing facilities that will include the closest approximation to the flight environment as possible and allow us to verify requirements and validate the design of the Starlab space station,” Starlab CEO Tim Kopra said in a news release.

Starlab’s grant comes on top of a $217.5 million award from NASA to help eventually transition activity from the soon-to-be-retired International Space Station to new commercial destinations.

Intuitive Machines is a space exploration, infrastructure and services company. Among its projects are a lunar lander designed to land on the moon and a lunar rover designed for astronauts to travel on the moon’s surface.

The grants come from the Space Commission’s Space Exploration and Aeronautics Research Fund, which recently awarded $47.7 million to Texas companies.

Other recipients were:

  • Cedar Park-based Firefly Aerospace, which received $8.2 million
  • Brownsville-based Space Exploration Technologies (SpaceX), which received $7.5 million
  • Van Horn-based Blue Origin, which received $7 million

Gwen Griffin, chair of the commission, says the grants “will support Texas companies as we grow commercial, military, and civil aerospace activity across the state.”

State lawmakers established the commission in 2023, along with the Texas Aerospace Research & Space Economy Consortium, to bolster the state’s space industry.

Houston experts: Can AI bridge the gap between tech ambitions and market realities?

guest column

Despite successful IPOs from the likes of Ibotta, Reddit and OneStream, 2024 hasn’t provided the influx of capital-raising opportunities that many late-stage tech startups and venture capitalists (VCs) have been waiting for. Since highs last seen in 2021—when 90 tech companies went public—the IPO market has been effectively frozen, with just five tech IPOs between January and September 2024.

As a result, limited partners have not been able to replenish investments and redeploy capital. This shifting investment landscape has VCs and tech leaders feeling stuck in a holding pattern. Tech leaders are hesitant to enter the public markets because valuations are down 30 percent to 40 percent from 2021, which is also making late-stage fundraising more challenging. After all, longer IPO timelines mean fewer exit opportunities for VCs and reduced capital from institutional investors who are turning toward shorter-term investments with more liquid exit options.

Of course, there’s always an exception. And in the case of a slowed IPO market, a select slice of tech companies—AI-related companies—are far outperforming others. While not every tech startup has AI software or infrastructure as their core offering, most can benefit from using AI to revise their playbook and become more attractive to investors.

Unlocking Growth Potential with AI

While overall tech startup investment has slowed, the AI sector burns bright. This presents an opportunity for companies that strategically leverage AI, not just as a buzzword but as a tool for genuine growth and differentiation. Imagine a future where AI-powered insights unlock unprecedented efficiency, customer engagement and a paradigm shift in value creation. This isn’t just about weathering the current storm of reduced access to capital; it’s about emerging stronger, ready to lead the next wave of tech innovation.

Here's how to navigate the AI frontier and unlock its potential:

  1. Understand that data is the foundation of AI success. AI is powerful, but it’s not magic. It thrives on high-quality, interconnected data. Before diving into AI initiatives, companies must assess their data health. Is it structured in a way that AI can understand? Does it go beyond raw numbers to capture context and meaning—like customer sentiment alongside sales figures? Rethinking data infrastructure is often the crucial first step.
  1. Focus on amplifying strengths, not reinventing the wheel. The allure of AI can tempt companies into pursuing radical reinvention. However, a more effective strategy is to leverage AI to enhance existing strengths and address core customer needs. Why do customers choose your company? How can AI supercharge your value proposition? Consider Reddit’s strategic approach: They didn’t overhaul their platform before their 2024 IPO. Instead, they showcased the value of their vast online communities as fertile ground for AI development, leading to a remarkable first-day stock surge of 48 percent.

  2. Use AI as a customer-centric force multiplier. Companies with a deep understanding of their customer base are primed for AI success. By integrating AI into the very core of their product or service—the reason customers choose them—they can create a decisive competitive advantage based on delivering tangible customer value.

From Incremental Gains to Transformative Growth

This practical, customer-centric approach has the potential to help companies generate immediate growth while laying the foundation for future reinvention. By leveraging AI to optimize operations, deepen customer relationships, and redefine industry paradigms, late-state tech startups can not only survive but thrive in a dynamic market. The future belongs to those who embrace AI not as a destination but as a continuous journey of innovation and growth.

Houston joint venture secures $5.2M for AI-powered methane tracking tech

Fresh Funds

Houston-based Envana Software Solutions has received more than $5.2 million in federal and non-federal funding to support the development of technology for the oil and gas sector to monitor and reduce methane emissions.

Thanks to the work backed by the new funding, Envana says its suite of emissions management software will become the industry's first technology to allow an oil and gas company to obtain a full inventory of greenhouse gases.

The funding comes from a more than $4.2 million grant from the U.S. Department of Energy (DOE) and more than $1 million in non-federal funding.

“Methane is many times more potent than carbon dioxide and is responsible for approximately one-third of the warming from greenhouse gases occurring today,” Brad Crabtree, assistant secretary at DOE, said in 2024.

With the funding, Envana will expand artificial intelligence (AI) and physics-based models to help detect and track methane emissions at oil and gas facilities.

“We’re excited to strengthen our position as a leader in emissions and carbon management by integrating critical scientific and operational capabilities. These advancements will empower operators to achieve their methane mitigation targets, fulfill their sustainability objectives, and uphold their ESG commitments with greater efficiency and impact,” says Nagaraj Srinivasan, co-lead director of Envana.

In conjunction with this newly funded project, Envana will team up with universities and industry associations in Texas to:

  • Advance work on the mitigation of methane emissions
  • Set up internship programs
  • Boost workforce development
  • Promote environmental causes

Envana, a software-as-a-service (SaaS) startup, provides emissions management technology to forecast, track, measure and report industrial data for greenhouse gas emissions.

Founded in 2023, Envana is a joint venture between Houston-based Halliburton, a provider of products and services for the energy industry, and New York City-based Siguler Guff, a private equity firm. Siguler Gulf maintains an office in Houston.

“Envana provides breakthrough SaaS emissions management solutions and is the latest example of how innovation adds to sustainability in the oil and gas industry,” Rami Yassine, a senior vice president at Halliburton, said when the joint venture was announced.
