Data analysis for big industry came first — before the technology that can support this analysis even entered the scene. Ryan Sitton, CEO and founder of Pinnacle, a Houston company that offers its clients streamline data management, joined the Houston Innovators Podcast to discuss his passion is using data to drive better decision making to drive more sustainable and reliable operations.

"I was basically doing data analytics in the mid 2000s before it was sexy. I was pulling together data in chemical plants and refineries and trying to predict how these plants would behave with the data I had," Sitton says. "I realized early on how there was so much opportunity here — but we don't have the technologies or the methodology to do it."

But over the years, the technology has caught up and now Sitton is able to provide clients with even more data-driven solutions. Click here to read more.

Women in STEM are in Houston, writes Julia P. Clarke, an engineer at a local firm in town, but there's work to be done to making them stay. Supporting women across the science, technology, engineering, and mathematics fields begins in the classroom, she writes in a guest column for InnovationMap.

"I grew up in Jamaica and then immigrated to the United States. It wasn't until I was recognized by my high school teacher, Mrs. Owens, for my natural ability to excel in subjects like science and math that I fell in love with the basis of engineering," she explains. "Without the mentorship and investment of teachers and professionals throughout my career, I would not be where I am today." Click here to read more.

Phillip Yates, a Houston-area attorney, envisioned a company that could solve the societal problems that perpetuate poverty. He started Equiliberty, a technology company that's part financial resource and part social network, to help provide underrepresented individuals with educational resources to secure financial success and a space to use their talents to create community-driven wealth.

The platform provides business development services, educational resources, access to capital, and mentorship to help users find financial independence.

"When I created Equiliberty, I envisioned a world where everybody has access to mentors," said Yates in a press release. "I know firsthand the importance of having a supportive network and community dedicated to your success." Click here to read more.

How to attract and retain female engineers for the Houston workforce

guest column

As Houston continues to invest in resiliency for our growing city, a well-equipped workforce is needed to meet the demand for critical infrastructure. It is also important that in a city as diverse as Houston, the engineering and construction talent that encompasses our workforce is reflective of the city itself, aligning with our ever-changing demographics.

While women continue to make strides in the STEM field, according to Pew Research Center, women's shares in the field of engineering have inched up only slightly, from 12% in 1990 to 15% today. And while women now earn a majority of all undergraduate and advanced degrees, they remain a small share of degree earners in fields like engineering and computer science — areas where they are significantly underrepresented in the workforce.

Diversity yields creativity, and women bring a valuable and unique perspective to problem solving and innovation. I grew up in Jamaica and then immigrated to the United States. It wasn't until I was recognized by my high school teacher, Mrs. Owens, for my natural ability to excel in subjects like science and math that I fell in love with the basis of engineering. Without the mentorship and investment of teachers and professionals throughout my career, I would not be where I am today.

In Houston, it is not a question of talent — we have plenty of diverse talent, and many young women entering the engineering workforce. The issue we run into is keeping them here and elevating them to reach the pinnacle of their discipline.

If we want to inspire young women to join the field, and ensure more women remain in it, we need to invest in mentor relationships and create space and opportunities for successful women to grow into positions of leadership.

Invest

Many would agree that mentorship plays a key role in career growth and development, but we need to be specific about what that means and how to do it effectively. For a mentor relationship to be impactful, it needs to be continuous and personal. When girls are in grade school, they are impressionable and open to inspiration. We have the opportunity to help them build confidence and make a difference in their futures.

It is important to remember that women will need several mentors throughout their lives. Obtaining an engineering degree is not easy, and upon graduation, young professionals come to the realization that what was taught in school can be different from what a job requires. New mentors are needed throughout the many seasons of personal and professional growth, and it is the responsibility of successful women engineers to take the time to develop true, lasting relationships with the next generation. We need more individuals who are willing to reach out to young women at a relatable level and establish that personal touch.

Inspire

Once we have women committed to a career in engineering, how do we foster them to go further in the field? We need more females in leadership roles. The high school teacher I mentioned was female and African American. Being able to relate to her eliminated barriers for me. I told myself that if she can do this, and she believes in me and looks like me, then I can do this, too. Young women and professionals need to be able to look at a company or professional organization's board members and executives and see faces that look like their own.

Listen

Last year, over 20 million Americans were out of work due to COVID-19, yet as the pandemic eases, millions of women have yet to return to the workplace. While this may be due to a complex mix of factors, I am left wondering if business leaders are actually asking women why they haven't returned. Many companies make assumptions regarding women's priorities, needs and expectations, without having a conversation. We are left with a shortage in our workforce, which will impact Houston sooner than most cities, and there needs to be an open dialogue between businesses and women to discover what they need to be successful.

Lastly, as women, it is our responsibility to use our voice. If I were to have let the assumptions of others guide my life and career path, I would not be where I am today. If you can persist and you are resilient, you will succeed. Women are here, but let's work together to ensure they are here to stay.

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.

NASA unveils Artemis III astronauts at Johnson Space Center in Houston

To the moon

NASA on Tuesday, June 9, revealed the crew for its Artemis III mission, the next step in the space agency's plan to eventually land astronauts on the moon.

The announcement came two months after Artemis II's record-breaking trip around the moon that surpassed the distance record of Apollo 13.

NASA's Randy Bresnik, Frank Rubio, Andre Douglas and the European Space Agency's Luca Parmitano won't fly to the moon or land on the surface. Instead, they’ll orbit Earth while practicing docking their Orion capsule with two lunar landers.

“To the Artemis III crew, we wish you Godspeed on the journey ahead,” said NASA administrator Jared Isaacman.

Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin are racing to deliver the lunar landers. The two-week demo is targeted for 2027. Blue Origin suffered a recent setback when its massive rocket exploded during an engine-firing test on the launch pad in Florida, shaking nearby homes and illuminating the sky with an orange fireball.

NASA's Jeremy Parsons said the setback is a learning opportunity and that the space agency is confident Blue Origin's rocket will be ready in time.

NASA's Artemis program aims to return astronauts to the moon's surface for the first time since the 1970s. A recent revamp of the program announced by Isaacman aims to fast-track it similarly to the Apollo era, adding the upcoming spaceflight around Earth before eyeing a lunar landing in 2028.

“We are certainly humbled as a crew to be able to be your crew that executes this Artemis III mission in space,” said Bresnik, Artemis III commander.

Added Douglas, mission specialist: “My brain — it is going a mile a minute right now. But my heart, it is so warm. It is so full."

In May, NASA awarded hundreds of millions of dollars in contracts to four companies, including Blue Origin, to build landers, rovers and drones for a future moon base. Isaacman said the goal of the moon base is to lay the foundation for a Mars expedition.
