Adrianne Stone knows firsthand how lonely the startup founder journey is, so she set out to help create a community for founders when she started Bayou City Startups last year. Now, Stone shares on the Houston Innovators Podcast that her monthly happy hours attract over 50 attendees on average.

"Being the venture associate with Capital Factory in Houston, I'd seen what the Houston ecosystem had to offer. There were events — happy hours, coffee meet-ups, all these things," Stone says on the show. "But it was not just a casual networking event usually. I wanted a consistent community where I could show up and say, 'guys, I had the worst week,' to people who got where I was coming from and who could commensurate or lean in and help."

The next opportunity to network with Bayou City Startups is Tuesday, July 18, from 5 to 7 pm at Kirby Ice House. Read more.

When he was an internal medicine physician, Sarma Velamuri watched helplessly as a friend’s 22-year-old daughter lost her life to sepsis. He had to tell his friend that she would not be coming home.

“There are 300,000-plus people a year who die of sepsis,” says Velamuri. “It’s important that people understand it’s not just those who are most susceptible to infections.”

This fact is not only unfortunate, but preventable. And that’s why Velamuri, who describes himself as “a recovering hospitalist,” co-founded Luminare in 2014. A full-time CEO since 2017, Velamuri, who runs the company with co-founder and CTO Marcus Rydberg, is based in the TMC Innovation Factory. Read more.

Chances are, you've heard of 50 Cent — his 2003 album "Get Rich or Die Tryin'" was a soundtrack to many. But Curtis James Jackson III, 50 Cent's real name, has done a lot since gracing your radios. He moved to Houston in 2021 and founded the G-Unity Foundation. In May, he wrapped on the second year of the G-Unity Business Labs, a business development incubator for Houston Independent School District high schoolers.

"I’ve spent years donating my time and energy to communities in need. I started G-Unity to do the same—to give back to kids so they have it a little easier than I did," Jackson writes on the website. "Team building and entrepreneurship are skills I learned along the way, but they are so important to develop early. I look forward to G-Unity supporting programs that are doing the crucial work of teaching kids to excel at life."

Around 150 students participated, and the winners are splitting a $500,000 investment. Read more.

The 50 Cent-backed high school entrepreneurship program wrapped up its second year of operation after helping over 100 Houston-area students build their small business plans.

G-Unity Business Labs, sponsored by Curtis James Jackson III — better known as 50 Cent — and Horizon International Group, allowed participants to build their own small businesses from the ground up. This year's cohort featured a variety of businesses, from a Caribbean hot dog food truck to a financial literacy course on personal finance.

In its second year, the program encouraged innovation and taught business acumen to entrepreneurial-minded high school students, culminating in an opportunity to create their dream companies. During this 28 week entrepreneurial internship program, around 150 students from Madison, Worthing, Yates, Kashmere, Booker T. Washington, and Wheatley high schools learned how to transform an idea they were passionate about into a full fledged product they can pitch to investors.

The after-school program consists of three stages – the first 20 weeks are about getting familiar with business concepts and building connections with peers and teacher volunteers. The next eight weeks are spent in the incubation phase as students are split up into teams and local entrepreneurs lead lessons, helping them workshop their ideas into a fleshed out corporation, before finally the teams compete in Hustle Tank, where students pitch their ideas to a panel of celebrity and entrepreneurial judges. At the event in May, the panel included 50 Cent and Mattress Mack. The five winning teams are now eligible to split $500,000 in seed money for their companies.

Summer Reeves, VP of design of Umbridge, is in charge of managing the incubation phase and said she has noticed a significant shift in the ideas the student groups have come up with between the two cohorts of the program; the first year saw flashier tech pitches. But during the second year of the program, Reeves said the students sought to address issues they see in their day-to-day lives, including a group who worked to develop support services to aid formerly incarcerated individuals after they are released.

“This year, a lot of students were more on the practical side,” Reeves tells InnovationMap. “We actually had three teams that were focused on mental health apps which I think is a great example of what youth today are really focused on.”

Reeves started off as a mentor to four teams during the incubation phase of the program last year providing students with guidance on how to set up their business plans, create prototypes, and pitch their companies to investors. After three of her teams won the Hustle Tank competition previously, she took over planning the incubation phase and recruiting other local entrepreneurs to act as mentors.

“We give them recommendations on how to pitch and how to frame their pitch but they also have the ability to get creative so we had some students who did short skits — some that did raps and spoken word type things — lots of creativity,” Reeves says.

Patrice Allen, senior manager of G-Unity Business Labs, said they use the students’ individual strengths and creative thought processes to place them into their teams, including asking them in interviews at the beginning of the year to try to sell her a pen to understand their pitching process.

“That’s the question the students always remember,” Allen says. “‘Sell us this pen or pick something out and sell it to us.’ It’s the weirdest thing and they love it.”

In building the teams at each school, Allen worked with educators to make sure every team had students with a variety of communication and planning skills as well as financial awareness. But Allen felt students were most successful when they incorporated their personal interests into their product design. The first place team of Hustle Tank, Caribbean Hot Dog Boyz, was especially emblematic of this mindset as they combined one member's background of selling hotdogs with another’s Caribbean heritage to create a food truck that sells the unexpected combo of oxtail hotdogs.

“To actually taste the food that they prepared was phenomenal,” Allen says “I have never ever thought that oxtails on a hotdog would be good but everybody was floored.”

Elizabeth Martin, director of communications and marketing for Horizon who runs the behind the scenes of funding, said students from the winning teams are now working on solidifying their business plans to qualify for the funds from the G-Unity foundation to develop their companies. Martin also said 50 Cent will retain a relationship with these teams, acting with varying levels of involvement depending on his deal with the students as anything from a silent partner to an investor.

“They do not walk home with $500,000 in their back pocket,” Martin explains. “We are investing in (them) — not giving — it’s an investment.”

The future of this program is uncertain as the Texas Education Association’s takeover of HISD is still in its transition phase but Martin advised to keep a lookout for an ABC Nightline interview of 50 Cent discussing G-Unity Business Labs, which is expected to release soon.

"I’ve spent years donating my time and energy to communities in need. I started G-Unity to do the same—to give back to kids so they have it a little easier than I did," Jackson writes on the website. "Team building and entrepreneurship are skills I learned along the way, but they are so important to develop early. I look forward to G-Unity supporting programs that are doing the crucial work of teaching kids to excel at life.

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.
