New GHP leader takes helm, creates ‘shared leadership model’

mixing it up

The Greater Houston Partnership announced organizational changes under the tenure of its new president and CEO, Steve Kean.

Kean officially took on his new role earlier this month, after being named the next CEO this summer. The GHP's former president and CEO, Bob Harvey, announced his retirement in January.

In his first acts as CEO, Kean reshuffled his executive suite with a series of promotions.

Katie Pryor has been promoted to executive vice president and COO where she will lead the partnership’s development and revenue activities like long-term fundraising efforts, engagement opportunities, annual membership campaigns, special events and programs, and long-term fundraising efforts, oversee people and culture, finance and accounting, and information systems departments.

Taylor Landin was also promoted, as he was named executive vice president and chief policy officer, where he will continue to lead the team of public policy and advocacy professionals in policy priorities at the federal, state and local levels.

Kean also created the Office of the CEO, which will be composed of both Pryor and Landin, and the organization’s senior vice president and chief marketing and communications officer, Clint Pasche.

“I believe this shared leadership model will produce better outcomes on the strategies, opportunities, and issues we’ll address at the partnership,” Kean says in a news release.

GHP is Houston’s “leading business organization,” which has championed growth across a 12-county region by uniting business and civic leaders dedicated to Houston’s long-term success.

“I have always known Houston to be a region focused on creating opportunity, and as I’ve visited with many across our community over the last few months since my appointment, I have seen this opportunity-creation mindset in our region’s corporations and startups, political leadership, educational institutions, economic development partners and so many other organizations,” Kean, who once was the CEO of Kinder Morgan, adds in a news release. “There is strength in the unity of spirit we have here in Houston; and our ability to collaborate and work together is what sets us apart from other cities around the country.”

Houston-founded unicorn logistics company returns HQ to the Bayou City

coming home

While originally founded in Houston in 2020, Cart.com has called Austin home for the past two years. Now, the scaling software company is coming home.

Cart.com, a tech company providing commerce and logistical solutions for businesses, announced today that its corporate headquarters has returned to Houston amid its rapid growth.

“I couldn’t be happier to bring Cart.com back home to Houston as we continue to revolutionize how merchants sell and fulfill products to meet customers anywhere they are,” Cart.com Founder and CEO Omair Tariq says in a news release. “The idea for Cart.com was born in Houston and we’ve always maintained a strong local presence with the majority of our executive team and board based here. As our customer mix increasingly moves upmarket and our own needs evolve, I’m confident Houston has what we need as we look towards the next stage of Cart.com’s growth story.”

The company has raised over $400 million in venture funding over the past three years, and has grown a customer base of 6,000 users, supporting over $8 billion in gross merchandise value, according to Cart.com. After making several acquisitions, the company also operates 14 fulfillment centers nationwide.

Cart.com's most recent raise, a $60 million series C round this summer, was announced to support an international expansion. Last year, the company secured $240 million in equity and debt funding.

According to the release, the relocation comes at a time of "unprecedented growth" for the business, which calls out Houston's central location, transportation infrastructure, and dynamic business community.

“We’re thrilled to welcome Cart.com home and proud to have one of the country’s fastest-growing unicorns back in Houston,” Bob Harvey, president and CEO of Greater Houston Partnership, in the release. “Cart.com’s homecoming is a testament to why companies repeatedly choose Houston to scale their business with its diverse and dynamic economy along with its unparalleled talent pool that cuts across technology, professional services and global trade. We’re excited to support Cart.com’s continued growth and look forward to the company’s contribution to Houston’s growing tech community.”

Earlier this month, Tariq was named a regional winner in the Entrepreneur Of The Year program, run by professional services firm EY. He was one of 11 Houston-based executives named in the Gulf South region and now will move on to national Entrepreneur Of The Year program.

GHP names energy exec as new president and CEO

taking the lead

A longtime energy executive has been named the next president and CEO of the Greater Houston Partnership. He'll take on the new role this fall.

The GHP named Steve Kean, who currently serves as the CEO of Kinder Morgan Inc., to the position. He's expected to transition from CEO to board of directors member at Kinder Morgan on August 1. Kean will then assume his new position at GHP no later than Dec. 1.

Dr. Marc L. Boom, GHP board chair and president and CEO of Houston Methodist, made the announcement at a press conference June 21.

“Steve brings incredible business acumen and leadership skills to the organization," Boom says in a statement. "Coupled with an extraordinary passion for Houston, he will build on the Partnership’s momentum to continue to advance greater Houston as a region of extraordinary growth and opportunity.”

The GHP's outgoing president and CEO, Bob Harvey, announced his retirement earlier this year, and will remain in his position until Kean is onboarded. Kean was selected via a search committee established by 2022 board chair, Thad Hill. The committee was chaired by Marc Watts and included Boom, Thad Hill, Paul Hobby, Gina Luna, Eric Mullins, Armando Perez, and Ruth Simmons. The process, which looked at over 70 highly-qualified Houston leaders, also included the services of Spencer Stuart to manage the search.

“This last decade has been a dynamic time for Houston and the Partnership," Harvey says in a statement. "As a life-long Houstonian, it has been an honor to focus my efforts on supporting Houston’s continued growth and working with the business community to create opportunities for all Houstonians. This is an exciting time for Houston. I am very pleased that Steve is enthusiastic about leading the Partnership, and I look forward to the organization’s continued success under his leadership.”

With decades in the energy industry, Kean joined Kinder Morgan in 2002 and has served as COO, president of Natural Gas Pipelines, and president of Kinder Morgan Inc. before rising to CEO. He received a bachelor's degree from Iowa State University and his law degree from the University of Iowa.

“I’m grateful for the opportunity to serve our region in this role," he says. "I look forward to building on what Bob, the Board, members, and staff of the Partnership have accomplished. I know first-hand the opportunities that a vibrant business sector can create for people and communities. I look forward to expanding those opportunities further.”

Greater Houston Partnership leader to retire, executive search committee forms to find new CEO

transition plans

Bob Harvey, who has been at the helm as the Greater Houston Partnership for over a decade has announced his retirement plans.

In an announcement today, the GHP revealed that Harvey, the president and CEO of the organization since 2012, plans to retire at the end of the year.

“This last decade has been a dynamic time for Houston and the Partnership. As a life-long Houstonian, it is a true honor to wake up each day focused on supporting Houston’s growth and working with the business community to create opportunities for all Houstonians,” says Harvey in a news release. “The commitment of business leaders to the success of this region is inspiring, and I look forward to continuing to lead the Partnership over the next year as we move Houston forward.”

Thad Hill, the current board chair of GHP and president and CEO of Calpine Corporation, has created an executive search committee made up of Partnership board members and chaired by Marc Watts, the 2018 Partnership board chair and president of The Friedkin Group. According to the release, the search will be national but the new CEO will be expected to "have some working familiarity with Houston and its business community." Current staff members will also be considered.

“I want to thank Bob for his tremendous leadership over the last decade as we’ve made great strides as an organization and as a region,” Hill says in the release. “I am grateful that Bob will continue to advance the organization over the coming months as we begin the process to find his successor. Under Bob’s leadership, the Partnership plays an essential role in the inclusive growth and prosperity of our great community, and I am confident his successor will expand on that legacy.”

The GHP is an economic development organization that serves the 12-county region encompassing Houston. It also acts as the business community’s advocate within policy across the local, state, and federal levels.

Under Harvey, the GHP has rolled out several initiatives, including workforce development program UpSkill Houston, the Houston Energy Transition Initiative, and diversity, equity, and inclusion program One Houston Together.

“The Partnership is an outstanding organization with strong board and staff leadership, impeccable financials, and a mission-oriented bias for action to make Houston a better place to live, work and build a business,” Hill says in the release. “The next leader of the Partnership is set-up to succeed, and I look forward to the process to identifying this person who will continue the organization’s momentum forward.”

Houston saw the biggest year-over-year jump in tech job postings among the top 25 U.S. cities for tech job growth, according to this report. Photo via Getty Images

Houston ranks as the top market for tech job growth

By the numbers

Houston is experiencing a boom in tech employment.

A recent report from Dice, a job platform for the tech industry, says Houston saw the biggest year-over-year jump in tech job postings among the top 25 U.S. cities for those postings.

From January through October this year, the number of tech job postings in Houston soared 45.6 percent versus the same period a year earlier. That compares with a 22.8 percent statewide increase during the same time span.

“Although sometimes overshadowed by the cachet of Dallas, Austin, and San Antonio, Houston is absolutely a tech hub in its own right, attracting a mix of major tech companies and VC-backed startups to join its already established base of aerospace, defense, and energy companies,” Dice says.

For the one-year period covered by the Dice report, San Antonio witnessed a 17.3 percent rise in tech job postings, with Austin at 9.6 percent and Dallas at 7.7 percent.

In citing Houston’s astronomic showing, Dice notes that the region benefits from the presence of tech employers like Asurion, AWS, Fiserv, Dell, IBM, and Siemens, along with a number of venture-backed startups.

Top tech occupations in the Houston area include software developer/engineer, business analyst, .NET developer, data analyst/engineer/scientist, DevOps engineer, network engineer, and full stack engineer, according to Dice. The region’s average tech salary is $100,341.

More broadly, the Greater Houston Partnership forecasts healthy job growth in 2023 while noting that a recession could temper the growth.

A “short and shallow” recession in the first half of 2023 would mean a net gain of 60,800 jobs next year, the partnership says. If no recession hits Houston, that number could climb as high as 79,200 jobs. However, a prolonged recession would limit job growth to about 30,400 jobs.

The partnership predicts 2023 job growth will be strongest in the region’s construction, energy, government, health care, professional services, and restaurant sectors. Within the professional category, which includes tech services, the partnership anticipates the addition of anywhere from 2,000 to 7,900 new jobs next year.

Through the first 10 months of this year, the Houston area added 144,000 new jobs, according to data from the Texas Workforce Commission. In November, the region’s unemployment rate stood at 4 percent, down from 5.1 percent a year earlier.

“As we look ahead to 2023 and what the future has in store, I’m incredibly optimistic about Houston’s prospects, despite a possible recession,” Bob Harvey, president of the partnership, says in a news release. “We have our challenges — from ensuring we lead on the energy transition to effectively competing for top talent — but each time Houston has been underestimated, we’ve come out on top. I believe that will be the case once again.”

Venus Aerospace adds government, C-suite leaders following $91M raise​

new leaders

Fresh off its $91 million Series B, Houston-based Venus Aerospace has made several key additions and promotions to its leadership team.

The company says its expanded team will help it deploy its high-thrust rotating detonation rocket engine (RDRE), which completed its first U.S. flight test last summer.

"We flew the world's first high-thrust RDRE in just over four years on $80 million. We believe that makes it the fastest, most capital-efficient rocket engine program in history," Sassie Duggleby, co-founder and CEO of Venus Aerospace, said in a news release. "Adding this talent to our leadership team is how we bring that same discipline to the company itself, as we scale to meet the technical needs of defense and space customers who need range and speed legacy systems can't deliver."

The key hires include:

Lane Bodian, Vice President of Public Policy

Bodian previously served as the Principal Deputy Assistant Secretary of Defense for Legislative Affairs at the Pentagon.

Dan Rebnord, Director of Federal Government Relations

Rebnord most recently served as Senior Policy Advisor to a member of the Senate Armed Services Committee and previously worked in the Office of Legislative Affairs at the Department of Defense and as Staff Director for a national security subcommittee in the House of Representatives. Rebnord and Bodian will lead Venus' work with government stakeholders.

Tom Barron, Chief Operating Officer

Barron was promoted from his role as vice president of operations for Venus Aerospace. Before his time at Venus, he served as Special Assistant to the Secretary of Defense and consulted aerospace clients at McKinsey & Company. He also served as a U.S. Army Infantry and Special Forces officer.

Nick Cardwell, Chief Product Officer

Cardwell was promoted from his role as vice president of research and development. He previously held product and technology leadership roles at VC-backed tech companies in the San Francisco Bay Area and Austin.

Venus also named Cameron Taylor as its new vice president of operations, Sarah Boland Heine as its head of communications, Matt Stohr as its head of business development, and Sheila Menz as general counsel.

The company also announced a joint technology development agreement to advance the RDRE with defense giant Lockheed Martin last week. Through the partnership, Venus and Lockheed will focus on evaluating the RDRE's propulsion architecture in defense systems, specifically for precision fires applications where weapons are designed to accurately strike targets at long distances.

Lockheed Martin Ventures, the investment arm of the aerospace and defense contractor, is an investor in Venus Aerospace.

"Lockheed Martin is focused on rapidly delivering advanced capabilities that strengthen deterrence and provide decisive advantages for the warfighter," Tim Cahill, president, Lockheed Martin Missiles and Fire Control, said in a news release. "Our collaboration with Venus Aerospace allows us to evaluate a promising propulsion technology and determine how it can be integrated into future precision fires solutions. Efforts like this help accelerate innovation, reduce risk and shorten the path from emerging technology to operational capability."

Venus' RDRE is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus says the reusable, affordable and scalable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types. The company has previously estimated that the hypersonic market is projected to surpass $12 billion by 2030.

New report ranks Houston as America's No. 2 least safe city

Ranking It

A new study contains bad news for Houston. A report from personal finance website SmartAsset ranks the Bayou City as the second-least safe city in the U.S. among cities with at least 250,000 residents.

Only Memphis ranked worse than Houston.

The 2026 study looked at 83 U.S. cities' violent crimes, property crimes, traffic deaths, and disaster risk.

Houston fared poorly in all four: 11.5 violent crimes per 1,000 residents, 42.9 property crimes per 1,000 residents, 11.6 traffic deaths per 100,000 residents, and “very high” risk for natural disasters, which makes sense in a city prone to tropical weather and flooding.

For all cities in the study, disaster risk and traffic deaths were measured at the county level.

Houston is the only Texas city to rank in the bottom 10. The other cities are:

  • 1. Memphis, Tennessee
  • 2. Houston, Texas
  • 3. St. Louis, Missouri
  • 4. San Francisco, California
  • 5. Kansas City, Missouri
  • 6. Albuquerque, New Mexico
  • 7. Oakland, California
  • 8. Nashville, Tennessee
  • 9. Philadelphia, Pennsylvania
  • 10. Detroit, Michigan

“While no major population center is entirely free from danger, some are more successful than others at creating environments where people can live, work and travel with confidence,” SmartAsset says.

Although this study paints Houston in a poor light, other reports take a more positive view. The "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy ranked as No. 9 in America out of 393 cities with a population of 500,000 or more. Houston also boasts Texas’ 10th best park system, according to its ParkScore Index.

While SmartAsset has bad news for Houston, the Dallas suburb of Plano ranked as the study’s second-safest big city. Compared to Houston, Plano fared well in three of the four categories: 1.5 violent crimes per 1,000 residents, 14.7 property crimes per 1,000 residents, and 6.9 traffic deaths per 100,000 residents. Its only shortcoming is a “relatively high” risk for natural disasters.

Elsewhere in Texas:

  • Fort Worth ranked No. 22
  • Austin ranked No. 26
  • San Antonio ranked No. 54
  • Dallas ranked No. 73
