The cleantech innovation space has momentum, and Chevron strives to be one of the incumbent energy companies playing a role in that movement, Jim Gable, vice president of innovation at Chevron and president of Chevron Technology Ventures, shares on the Houston Innovators Podcast.

"People call it cleantech 2.0, but it's really cleantech 3.0," Gable says, explaining how he's been there for each wave of cleantech. "The people are better now — the entrepreneurs are better, the investors are better. Exits are here in the cleantech space."

"It's all driven by policy-enabled markets, and the policy is here now too. Twenty years ago, you didn't have nearly the same level of policy influence that you do now," he continues. "Things are coming together to help us really create and deliver that affordable, reliable, ever cleaner energy that's going to be needed for a long time." Read more.

When it comes to marketing tools, there's a lot out there. Some aren't worth it, but some can make a huge difference. Chris Romani, chief marketing officer for illumiPure, Houston-based medical device company, in a guest column for InnovationMap, outlined some of the tools that make an impact.

"For startups, when and how to begin marketing their business can feel like a cumbersome task," he explains. "As a chief marketing officer, I was asked to list services and channels that I oversee, and I came up with 16. For founders of startups who must often take on the roles of CEO and COO in addition to CMO as they look to expand their teams, that time commitment is not reasonable for someone who also has a personal life."

How to leverage mobile marketing for your startup, according to this Houston expert

Guest column

Consumer privacy is driving startups to immediately begin marketing and data collection. Google and Apple have recently stressed the importance of first-party data collection for businesses. For the last two decades, businesses have had access to cookies to advertise to people who visited their digital assets. Digital advertising has already changed with Apple’s iOS 14.5 alterations, switching the default of ad tracking from yes to no and both Google and Apple expect data privacy to increase.

For startups, when and how to begin marketing their business can feel like a cumbersome task. As a chief marketing officer, I was asked to list services and channels that I oversee, and I came up with 16. For founders of startups who must often take on the roles of CEO and COO in addition to CMO as they look to expand their teams, that time commitment is not reasonable for someone who also has a personal life.

Entrepreneurs need tools that are simple to institute and not cost prohibitive, to meet their respective milestones. First, we need to collect first party data, so that when we get to our minimum viable product we have plenty of people waiting to buy it. Next, marketing must work even when we can’t focus on it. Third, we must focus on revenue generating activities, whether they are marketing or not. Finally, we want to create an environment where successful entrepreneurs have a work and life balance.

Before doing anything else — get a virtual phone number

A virtual phone number is the first marketing tool I would use for any business. This number can be connected to your cell phone during certain hours of the day and disconnected for others. This allows people to reach you on your schedule. Put this phone number on every asset you have, so it can be integrated into future tools, such as customer relationship management and Google My Business. With proper opt-in information, it also creates an immediate list for SMS marketing in the future. A virtual phone number typically runs $1 to $2 a month plus usage fees, so it can be used by any business.

It is important that this is set up first, because without this, you can’t use the following marketing tools effectively.

Tool 1: Missed Call – Text Back

An entrepreneurs’ worst nightmare is missing an important phone call, whether it’s an investor or closing your first sale. Constant phone and email checking causes anxiety, but more importantly, it is a low revenue activity, so you are actively hurting your business.

Missed Call – Text Back, or MCTB, allows a customizable text message to be delivered to a client when you miss their phone call. It moves the caller towards resolution (sales or otherwise) immediately encouraging them to give you more information about their problem. The best part is, that once you have the system in place, it costs you zero time. Imagine walking out of a meeting and instead of 10 missed calls, you have 10 text messages that you can quickly answer. How much time did you just get back?

Pro Tip: In many cases, you can automate your emails in a similar way.

Tool 2: A funnel page

Now that we have a tool that allows us to work productively without constant phone checking, we need to increase our book of business. This is where a funnel comes in.

A funnel is a unique digital experience you would like a specific person — a client or investor — to have. When you start a business, a funnel can be your website because you only have one specific thing you want any visitor to do, like collect information.

Almost every consultant to new businesses is promoting funnel building. Why? Because a good funnel motivates people to act in a specific way. If you are raising funds, you want an investor to have a specific experience to garner interest, not hope they navigate to the correct webpage. If you have a new technology, you want early adopters to learn and then provide a simple way to collect their information, so that you can contact them when your product is ready. Finally, if you’re about to hit the market with your new product, providing customers with a simple purchase method will improve revenue during your important proof-of-concept period.

Funnels, like MCTB, can grow and adapt with your business, providing different groups of people with different experiences, with minimal effort. For instance, suppose I created a dating app and needed early adopters. Instead of creating one funnel, let’s say I created two. The only difference between the two funnels, is the first one’s headline was “The No. 1 new dating app for men” and then the second one said women. Everything else remains the same, but the experience is immediately different for the consumer. The more you can change the funnel to cater to their personal experience, the better it will be, but even simple changes can go a long way.

Pro Tip: Funnels are easiest to keep track of when they are subdomains of your website.

Tool 3: Automated SMS marketing

The final tool I recommend to start is Automated SMS Marketing. Assuming you have people properly opted in from your funnel — review Telephone Consumer Protection Act (1991) to ensure legal compliance — you can make sure they receive a welcome message in the first 5 minutes.

The most important part of text messaging marketing is allowing your customer to believe they are really having a conversation with you. If you can avoid it, never tell a customer that your digital number is automated. If you need, tell them it is automated but overseen by you. You are the owner of the business or the inventor of the technology, people want to talk to you. Customers want to pretend that they know you. Allow them this feeling. Once the customer responds, you should be picking up an organic conversation with them anyway.

Bringing it together

Using these tools, we have created a simple, repeatable method to gather customer data and start their customer journey. Your funnel may also help you gather an email list, but your most active prospects will be more than willing to communicate with you over the phone.

When you can’t take calls, whether it’s because you are in a meeting or with your kids, you can rest easier, knowing that potential customers get an immediate response that helps them get where they need to go, or at the very least, when you get back to work, you can help them quickly.

And the best part for a new entrepreneur is that this can all be done cost effectively. Personally, I recommend a service called HighLevel, a feature-rich cost-effective CRM, that includes all of the tools previously discussed. Most tech savvy entrepreneurs can figure out how to institute all these practices quickly from one platform in a no code environment. If you’d rather have assistance, there are 20,000 agencies that use the platform and just as many YouTube videos.

5 Houston deep tech startups pushing the boundaries of their industries

meet the finalists

Houston has long been at the forefront of innovation, from NASA’s Johnson Space Center to its startup ecosystem using technology to disrupt industries.

As part of the 2026 Houston Innovation Awards, our Deep Tech Business category will honor an innovative startup providing technology solutions based on substantial scientific or engineering challenges, including those in the AI, robotics and space sectors.

Five deep tech companies have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Casimir

Battery tech startup Casimir develops semiconductor chips that produce continuous electrical power straight from the quantum vacuum, without the need for a battery, cord or external charge source. The company is targeting commercialization for its first-generation MicroSparc chip by 2028.

Harold “Sonny” White founded Casimir in 2023 after nearly two decades at NASA. The company emerged from stealth with a $12 million seed round in 2026. It was also awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force earlier this year.

FocisAI

Artificial intelligence startup FocisAI helps refinery owner-operators unlock actionable insights from 3D scans and images.

FocisAI was founded by CEO Tyler Wooten, COO Colin Snell and CTO Kyle Snell in 2026. It is a member of Greentown Labs and launched a seed round in September, which is expected to close by the end of the year, according to the company's application. It has rolled out 10 pilot programs and is looking to move into recurring, facility-scale deployments and scale its team in Houston this year.

Machine Saver Inc.

Industrial tech startup Machine Saver Inc. builds wireless and wired vibration and proximity sensors to tell heavy industry when a machine is about to fail. The company's technology runs on an 8-plus-year battery life and helps operators reduce downtime, improve maintenance and extend equipment life.

Machine Saver was founded by CEO Colton Bach and Quentin Bach in 2013. Its customers and partners include Houston Methodist, Blue Bell, Genemco, as well as energy and heavy industry, food and beverage, and cold chain companies, according to its application. The company is raising a Series A.

Square Robot

Energytech startup Square Robot develops and operates submersible inspection robotics that inspect aboveground storage tanks while they remain in service. The robots reduce downtime and costs, improve worker safety and limit hydrocarbon emissions.

Square Robot launched its Houston office in 2019 and closed a Series B in 2025. It plans to complete its first U.S. Navy demonstrator tank in November and is also developing real-time inspection software.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

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.
