When something is declared clean, one question invariably springs to mind: just how clean is clean?

Then it is, “What metrics decide what’s clean and what’s not?”

To answer those questions, one must abandon the subjective and delve into the scientific — and that’s where Clean Habits come in. The company has science on its side with Synbio, a patented cleaning formula that combines a unique blend of prebiotics and probiotics for their signature five-day clean.

“Actually, we are a synbiotic, which is a prebiotic and a probiotic fused together,” says Kristy Phillips, founder and CEO of Clean Habits. “And that's what gives us the five-day clean, and we also have the longest shelf life — three years — of any probiotic on the market.”

Phillips learned about the European product almost three months before the COVID-19 pandemic. She had heard of probiotics for gut health but had no idea about probiotic cleaning.

“When COVID actually hit, I went back and really started researching the manufacturer who is based in Europe and all of their pre- and probiotic cleaners,” remembers Phillips. “And I just found it to be so interesting that they were using natural probiotics from the dirt, from the soil, from Mother Earth. And they created this entire product line that they have been using for over 15 years. And they had so many clinical trials and hospital studies and university studies that were showing that these probiotic cleaners were working, and they were reducing bacteria, viruses, even viruses in air.

“Not only were they in the cleaning spray sector, but they were also already in water purification. They were in agriculture for animal house farming. They were doing a big trial in the subway station in Milan, putting the probiotics through a big HVAC system. And I just thought, there must be something here.”

Phillips was right. After reaching out to the manufacturer, she asked if they had a distributor here in the United States. They didn't.

“Since they didn’t have a distributor here in the U.S., I got the products and tried them out for myself,” says Phillips. “They were chemical-free, non-toxic and eco-friendly and after comparing them side-by-side with the commercial cleaners we all grew up with like the Lysols, bleach, and 409s, I found that the probiotic cleaners not only worked on surface areas to remove bad bacteria and germs, they continued to work for up to five full days at 100 percent.

“The commercial cleaners did kill 99.99 percent of all bacteria and germs, but they only did it for 30 minutes. And then the bacteria and germs start to grow back. And I am like, you know, nobody tells you that in their marketing. So that is what started my journey on the probiotics and creating a line to bring to the market here in the United States.”

Phillips soon realized that her goal was easier said than done.

“I think the U.S. market is one of the hardest to break into,” says the Houston native. “Trying to launch a brand-new product in the United States, in the cleaning sector, you do have to deal with the FDA and the EPA, there is a big game that you must play. And then you do go up against the big boys, like the Johnson and Johnson's of the world. Everybody is so used to chemical cleaning. And to go and try to change that industry and disrupt it, that can be tough for people.

“And at the time, I felt like it was insane because everyone was living in their house due to COVID and continuing to use commercial cleaners that are backed with chemicals. They were all breathing that in. I felt that was doing us all an injustice, especially when you have these probiotics that are natural, non-toxic, non-chemical and safe to breathe. It does change the game.”

Once Phillips noticed that she was not alone, with companies like Jessica Alba’s The Honest Company and Mrs. Meyer’s with their plant-based cleaning products, she forged full speed ahead with Clean Habits.

Now, more than three years later, her company is making a significant impact.

“I said, OK, I’m not crazy here, I must be on the right path,” says Phillips. “With people starting to recognize that there is a better way to clean, we began to get into retailers like Kroger. Right now, we are in the process of on-boarding with Walmart and are in talks with CVS, Whole Foods, and Costco.”

The biggest signal to Phillips that the word was out on Clean Habits came in the form of a potential celebrity endorsement.

“Howie Mandel, who is a certified germaphobe, reached out to us a couple of weeks ago,” says Phillips, who before her mission to clean up the world, was a producer of reality television. “We are about to do a big campaign with him and the Clean Habits line. People know Howie Mandel. So, he is definitely going to bring more awareness to our brand, which will allow us to start a big, heavy push and hopefully we can just capitalize on it and go from there.”

Moving forward, Phillips’ vision for Clean Habits will extend beyond just traditional cleaning products. She sees that she can also have an impact on the industrial and commercial side of things.

“Right now, we are doing testing in agriculture, and this is something that our manufacturers in Europe have already done and they have been extremely successful with it,” says Phillips. “The goal is to see if we could reduce the use of pesticides in farming and replace it with just misting and spraying with the probiotics.

“We already know that by incorporating the probiotics throughout water systems, that we can actually clean the water and take it back to 100 percent natural water or pure water. We can get rid of E. coli, MRSA, staph. And so, we are going to start working with the state of Texas and into animal house cleaning and farming and cleaning their water.”

Additionally, Clean Habits already has research that proves that by incorporating the probiotics, they can start eliminating the bird flu, which affected a lot of Texas chickens recently to where over 350,000 of them had to be put down.

“We’re really trying to change the faith there in agriculture,” says Phillips. “I mean, to me, it's amazing because when I first started this, I was just trying to launch some cleaning supplies, which is fantastic, but this product is so much more than a multi-purpose cleaning spray, your floor cleaner, your drain cleaner or your laundry detergent. This goes into cleaning water, which is everyone's basic right to have clean water. And the fact that we can do it by using these probiotics, to me, my little brain can't compute that part of it.

“And then when we really did start looking into the agriculture and how, by incorporating the probiotics into the animal house, the cleaning of the water, and putting it into their housing system, that we can reduce methane gas by 41 percent. That is huge. This can profoundly change and revolutionize industries. And to be a part of that, and I am so excited.”

Houston ranks among world’s top 30 emerging startup ecosystems

Startup Status

Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

“For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”

KBR names C-suite duo to lead $5.3B government services spinoff

new leaders

In advance of the spinoff of its Mission Technology Solutions unit, Houston-based KBR has made two C-suite hires for the new business.

Michael LaRouche is coming aboard as president and CEO of the spinoff, currently called SpinCo, on Sept. 26. Nicholas Veasey is joining as executive vice president and chief financial officer on July 1.

“Michael and Nick bring a highly complementary combination of operational leadership, financial expertise, and mission-driven experience, and together they will accelerate our impact for stakeholders,” Stuart Bradie, chairman, president and CEO of publicly traded KBR, said in a news release.

LaRouche currently is CEO of Serco North America, a Herndon, Virginia-based government services contractor. Veasey most recently was CFO of MAG Aerospace, a Fairfax, Virginia-based defense contractor.

SpinCo, a government services contractor, will launch with more than $5.3 billion in annual revenue and 20,000 employees. KBR’s total headcount is around 36,000. Branding for SpinCo, including a formal name, will be revealed in July.

“SpinCo is positioned as a top-tier provider of differentiated technology solutions, anchored by deep mission expertise, global scale, and a relentless commitment to delivering for our customers,” LaRouche says.

After the spinoff, the slimmed-down KBR will focus on its Sustainable Technology Solutions business, a provider of energy and industrial technology that generated $2.5 billion in revenue in 2025. Bradie will remain chairman, president and CEO of the business.

Both SpinCo and the new KBR will be public companies. The spinoff is scheduled to be completed in January.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
