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.

50 Cent's Houston entrepreneurship program wraps with $500,000 investment into student-founded companies

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.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
