All signs point to Texas leading the development of a hydrogen market, says one new report out of Rice University.

The Baker Institute for Public Policy released a new report this week about the hydrogen economy and the role Texas will play in it. According to the experts, Texas’ legacy energy industry — as well as its geology — makes it an ideal hub for hydrogen as an energy source. Ken Medlock, senior director of the Baker Institute’s Center for Energy Studies, and Shih Yu (Elsie) Hung, research manager at the center, wrote the report.

“Texas is in a very advantageous position to play a leading role in driving hydrogen market growth, but the evolution of policy and market structure will dictate whether or not this comes to pass,” write the co-authors.

3 Houston companies land on Deloitte’s Technology Fast 500 list

trending up

Three Houston companies have made this year’s Deloitte North America Technology Fast 500 list.

The report ranks the fastest-growing technology, media, telecommunications, life sciences, fintech, and energy tech companies in North America. The Houston companies to make the list, along with their revenue growth rates from 2021-2024, include:

  • No. 16 Action1 Corp., a provider of cybersecurity software. Growth rate: 7,265 percent
  • No. 92 Cart.com, a commerce and logistics platform. Growth rate: 1,053 percent
  • No. 312 Tellihealth, a remote health care platform. Growth rate: 244 percent

“Houston’s unique blend of entrepreneurial energy and innovation continues to strengthen the local business community, and I’m thrilled to see Houston companies honored on the 2025 Deloitte Technology Fast 500 list. Congratulations to all the winners,” said Melinda Yee, managing partner in Deloitte’s Houston office.

Action1 is no stranger to lists like the Deloitte Technology Fast 500. For instance, the company ranked first among software companies and 29th overall on this year’s Inc. 5000, a list of the country’s fastest-growing private companies. Its growth rate from 2021 to 2024 reached 7,188 percent.

Mike Walters, president and co-founder of Action1, said in August that the Inc. 5000 achievement “reflects the dedication of Action1’s global team, who continue to execute against an ambitious vision: a world where cyberattacks exploiting vulnerabilities are entirely prevented across all types of devices, operating systems, and applications.”

Atlanta-based Impericus, operator of an AI-powered platform that connects health care providers with pharmaceutical and life sciences companies, topped the Deloitte list with a 2021-24 growth rate of 29,738 percent.

“Our mission is to set the standard for ethical AI-powered physician connections to pharma resources, accelerating and expanding patient access to needed treatments,” said Dr. Osama Hashmi, a dermatologist who’s co-founder and CEO of Impiricus. “As we continue to innovate quickly, we remain committed to building ethical bridges across this vital ecosystem.”

How executive education retains your best employees + drives success

Investing in People

Hiring is tough, but retaining great people is even harder. Ask almost any manager what keeps them up at night, and the answer usually comes back to the same thing: How do we keep our best employees growing here instead of looking elsewhere?

One reliable approach has held up across industries. When people see their employer investing in their development, they’re more likely to stay, contribute, and imagine a future with the organization.

The data backs this up. Employees who take part in ongoing training are far less likely to leave, and the effect is especially strong for younger workers. One national survey found that 86% of millennials would stay with an employer that invests in their development. Companies that build a real learning culture see retention jump by 30-50%. The pattern is consistent: When people can learn and advance, they stay.

The ROI of executive education
Professional development signals value, but it also builds capability. When people have access to structured learning, they become better problem-solvers, more adaptable, and more confident leading through change.

That's the focus of Executive Education at Rice University's Jones Graduate School of Business. The portfolio is built for the realities of modern leadership: AI and digital transformation courses for teams navigating new technologies, and deeper programs in innovation and strategy for leaders sharpening long-term thinking.

“People, managers, professionals, and executives in all functional areas of business can benefit from this program,” notes Jing Zhou, Mary Gibbs Jones Professor of Management and Psychology at Rice. “We teach the fundamental principles of how to drive innovation and broaden the cognitive space.”

That perspective runs through every offering, from the Rice Advanced Management Program to the Leadership Accelerator and Leading Innovation. Each program gives participants practical tools to think strategically, work across teams and make meaningful change inside their organizations.

Building the leadership pipeline
Leadership development isn’t a perk anymore. It’s a strategic need for any organization that wants to grow and stay competitive.

Employers know this — nearly two-thirds say leadership training is essential to their success — yet employees still report feeling stalled. Reports find 74% of employees feel they aren’t reaching their potential because they lacked meaningful growth opportunities.

Rice Business designs its Executive Education programs to address that gap. The Rice Advanced Management Program, for example, supports leaders preparing for C-suite, board, or enterprise-level roles. Its format — two in-person modules separated by several weeks — gives participants space to test ideas at work, return with questions, and build on what they’ve learned. The structure fits demanding executive schedules while creating room for deeper reflection and richer peer connections.

Just as important, the program helps senior leaders align on strategy and culture. Participants develop a shared language and build stronger relationships, which translates into clearer decision-making, better collaboration, and less burnout across teams.

Houston’s advantage
Houston gives Rice Business Executive Education a distinctive edge. The city’s position in energy, healthcare, logistics, and innovation means participants are learning in the middle of a global business ecosystem. That proximity brings a mix of perspectives you don’t get in more siloed markets, and it pushes leaders to apply ideas to real-world problems in real time.

The expertise runs deep on campus, as well. Participants learn from faculty who are shaping conversations in their fields, not just teaching from a playbook. For many organizations, that outside perspective is a meaningful complement to in-house training — a chance to stretch thinking, challenge assumptions, and broaden leadership capacity.

Rice Business offers multiple paths into that experience, from open-enrollment programs like Leading Organizational Change, Executive Leadership for Women, or Driving Growth through AI and Digital Transformation to fully customized corporate partnerships. Across all formats, the focus is the same: education that is practical, relevant, and built for impact.

Investing in retention and results
When organizations make room for real development, the payoff shows up quickly: higher engagement, stronger leadership pipelines, and lower turnover. It also shapes the culture. People are more willing to take risks, ask better questions, and stay curious when they know learning is part of the job.

As Brent Smith, senior associate dean for Executive Education at Rice Business, explains, “There’s a layer of learning in leadership that’s about helping people adopt a leadership identity — to see themselves as the actual leader for their organization. That’s not an easy transition, but it’s the foundation of lasting success.”

For companies that want to build loyalty, deepen leadership capacity, and stay competitive in a fast-changing environment, investing in people isn’t optional. Rice Business Executive Education offers a clear path to do it well. Learn more here.
