Thomas Vassiliades has been named CEO of BiVACOR, and he replaces the company's founder, Daniel Timms, in the position. BiVACOR is on track to head toward human clinical trials and commercialization, and Vassiliades is tasked with leading the way.

Vassiliades has over 30 years of experience within the medical device industry as well as cardiothoracic surgery. He was most recently the general manager of the surgery and heart failure business at Abiomed and held several leadership roles at Medtronic. Dr. Vassiliades received his MD from the University of North Carolina, and his MBA was achieved with distinction at Emory University.

“I am excited and honored to join the BiVACOR team, working closely with Daniel and the entire team as we look forward to bringing this life-changing technology to the market,” says Dr. Vassiliades in the release. “Throughout my career, I’ve been guided by the goal of bringing innovative cardiovascular therapies to the market to improve patient care and outcomes – providing solutions for those that don’t have one. BiVACOR is uniquely well-positioned to provide long-term therapy for patients with severe biventricular heart failure.” Click here to read more.

Katie Mehnert started ALLY Energy — originally founded as Pink Petro — to move forward DEI initiatives, and she says she started with building an audience first and foremost, but now the technology part of the platform has fallen into place too. Last summer, ALLY Energy acquired Clean Energy Social, which meant doubling its community while also onboarding new technology. On the episode, Mehnert reveals that this new website and platform is now up and running.

"We launched the integrated product a few weeks back," Mehnert says. "The whole goal was to move away from technology that wasn't serving us."

Now, moving into the new year, Mehnert is building the team the company needs. She says she hopes to grow ALLY from two employees to 10 by the end of the year and is looking for personnel within customer support, product developers, and sales and service. While ALLY is revenue generating, she also hopes to fundraise to further support scaling. Click here to read more.

The state of Texas is about a month away from the one year anniversary of Winter Storm Uri — but is the state better prepared this winter season? Don Whaley, president at OhmConnect Texas, looked at where the state is now versus then in a guest column for InnovationMap.

"Governor Abbott has gone on record guaranteeing that the lights will stay on this winter, and I am inclined to agree. With the reinforcement of our fuel systems being mandated by the Railroad Commission, 2023 to 2025 should receive the same guarantee," he writes. "Beyond that, as the demand for electricity in Texas continues to grow, we will need to rely on the initiatives under consideration by the PUCT to attract investment and innovation in new, dispatchable generation and flexible demand solutions to ensure long-term stability in the ERCOT market.

Whaley has worked for over 40 years in the natural gas, electricity, and renewables industries, with specific experience in deregulated markets across the U.S. and Canada. He founded Direct Energy Texas and served as its president during the early years of deregulation. Click here to read more.

Opinion: Houston energy expert weighs in on if the state's power grid is ready for winter

guest column

The Winter Storm Uri, which struck Texas in February of 2021, was an unprecedented event in both severity and duration. At its most extreme, temperatures were as much as 40 to 50 degrees below their historic averages. The storm resulted in the largest controlled blackout in U.S. history, forcing the shedding of more than 23 gigawatts of load, the loss of power to 4.5 million homes and businesses for periods of one to four days, and the tragic loss of hundreds of lives.

A crisis of this magnitude has resulted in an intense re-examination of the Texas power grid. Not surprisingly, it has also resulted in record levels of finger-pointing and an ongoing search to identify the parties responsible. Among the casualties were all three Public Utility Commissioners that regulate the industry and a virtual purge of ERCOT, the organization that operates and manages the grid.

The Texas 87th Legislature filed an inordinate number of bills to address the electric system's failings, and Governor Abbott’s office has been vocal and actively working to ensure that there will never again be a repeat of the events of February 2021. The principal focus of the now reconstituted and expanded Public Utility Commission of Texas (PUCT) has been defining and implementing changes to system rules and operations in order to extract a greater degree of reliability from existing assets and incentivize the construction of significantly more MW of dispatchable generation. Many of the changes implemented by the PUCT will provide the market with a greater cushion against shocks to the system, moving the market away from a crisis management mode and towards a more proactive footing. We can expect even more change once current policies are assessed and more aggressive proposals are analyzed to determine whether they offer more benefit than harm to the market.

Amid all the debate, discussion, and wringing of hands, only one report has come close to identifying the smoking gun at the center of the crisis: the need for weatherization. The notion that weatherizing of generating assets is the key to future reliability has been discussed ad nauseum, but the report issued by the Federal Energy Regulatory Commission on November 16, 2021, attributes an equal share of the blame to the natural gas producing, processing, and transportation sector and its inability to perform reliably under the harsh conditions of Uri.

In the areas affected worst by the storm, gas production in Texas, Oklahoma, and Louisiana fell by more than 50 percent at its lowest point when compared to average production in the prior month. The Railroad Commission, not the Public Utility Commission, regulates natural gas transmission, and it was slow off the mark given the focus on generation. The Railroad Commission has now begun to implement weatherization requirements, with new initiatives slated to be in full effect for the winter of 2023.

It is imprudent to use “never” as a time scale, but I would place the probability at “remote” that Texas will see a recurrence of the events of February 2021 in 2022. In the unlikely event we did, the impacts would likely pale in comparison to those experienced last February. This is due both to the heightened state of preparedness with which the industry will approach the coming winter and the impact of changes put into effect by the PUCT as of January 1, 2022.

Governor Abbott has gone on record guaranteeing that the lights will stay on this winter, and I am inclined to agree. With the reinforcement of our fuel systems being mandated by the Railroad Commission, 2023 to 2025 should receive the same guarantee. Beyond that, as the demand for electricity in Texas continues to grow, we will need to rely on the initiatives under consideration by the PUCT to attract investment and innovation in new, dispatchable generation and flexible demand solutions to ensure long-term stability in the ERCOT market.

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.
