Two Houston companies formalized their partnership this year. Bayou City Hemp Company announced that it has purchased 8th Wonder Brewery, Distillery, and Cannabis. The acquisition deepens a relationship that dates back to 2021, when 8th Wonder and Bayou City Hemp partnered to create Wonder Water, a non-alcoholic beverage available with either CBD or Delta-8 that became the top-selling to-go product at 8th Wonder. Now, the combined company creates adult beverages by offering a full lineup of beer, spirits, and cannabis-infused drinks.

Innovative Houston couple designs wine-cooling device

drink this in

Great inventions reveal their value within due course, but there are those creations that tell their worth almost immediately, with a first look, image, or mere mention.

The Cold Cork, a malleable pouring device that instantly chills wine and spirits, falls into that category.

It seems like such a simple idea, but that’s the thing about inventions, isn’t it? Anyone can come up with an idea, but it’s the ones that can execute that idea that make it to the finish line and etch their names in the annals of creative glory.

“I had come home from the grocery store, right at the onset of COVID, and I wanted to have a glass of wine that I bought, but it was already room temperature, and I didn't want to put ice in it,” says wine-lover and former healthcare worker Michelle Kurkiewicz. “So, we started doing some research and came up with the idea for Cold Cork.”

Timing is everything, and because the nationwide pause caused by the COVID-19 pandemic offered Michelle, 33, and her husband Tyler, 30, plenty of free time, the dutiful duo was able to flesh out their labor of love.

As it turns out, Tyler, a mechanical engineer by trade, had recently purchased a 3D printer back in January 2020, so he was able to use it to build hundreds of prototypes in-house to eventually arrive at a final design, which is based on the couple’s wedding champagne flutes.

So how does the Cold Cork work? Picture this: the wine-lover takes the Cold Cork out of the freezer (after a recommended 24 hours to thoroughly freeze), places it on top of the open bottle of wine and begins to pour.

As the liquid funnels through the stainless-steel coil, which is surrounded by a proprietary, food-grade cooling medium, the wine or spirits is chilled by 20 degrees in just 20 seconds.

To achieve the best results for red wine, pour the entire bottle through the Cold Cork into a decanter and enjoy.

And the best part? Not one part of the Cold Cork’s signature process alters the taste or composition of the drink in any way.

“At first, we thought about whether the product should be inside the bottle or outside the bottle,” remembers Tyler. “But we quickly realized that there’s simply not enough room to do that amount of chilling inside a bottle. And we didn't want to have to pour any wine out. But we needed to make space to put some sort of chiller in the bottle. And so, we immediately started looking outside the bottle, and just with all the other wine gadgets, being bottle-topped and plugging in with a rubber stopper, that's immediately the direction we sort of drifted to.”

According to Tyler, the first couple of prototypes were made of a 3D filament. Initially, the idea was to focus on creating a cooling gel to compliment the coil, but that got a bit messy and, of course, there were too many wine taste-testing sessions to count.

“We definitely went through a lot of bottles of wine,” says Michelle. “But one of the first people that used our product was a sommelier and she loved it. We also gave one of our first production-level prototypes to a friend who is a manager at a restaurant. She used it on several occasions and said it was perfect for what she needed and seeing our product be used at a place that we frequented was extremely validating.”

Armed with the validation they needed to go to production, the wine-loving public could now have the product they needed to keep from having to throw all their wine in the refrigerator.

“The Cold Cork is really good for the people that maybe don't have those multi-zone fridges,” says Michelle. “We found a good niche with entry-level wine drinkers that don't have a wine fridge, but they want to drink their white wines still without being over-drank with ice cubes.

“That's really who we've been going after, and who we've seen has found a lot of value in the product. It's really the people that maybe aren't so prepared or maybe looking just for some more accessible solutions, whether it's because of the space in their apartment or financially, you know, it might be cheaper than a wine fridge. That's why we came up with the Cold Cork ourselves, because that was us, and so we kind of made a product that worked for us and found that there are a lot of people like that.”

The Cold Cork is available now and can be purchased directly from the company’s website for $64.95. In the future, more cork sizes and different colors will be offered, and more brick-and-mortar stores will carry the product. The couple pitched the idea and received investment from Trend Ventures at the 2022 Build Up Buttercup, an initiative that featured small business pitches for a select group of investors.

“We’ve gotten a lot of feedback directly from customers saying they use it a lot more than they thought,” says Michelle. “But then there are those people that are skeptical about how it works. That’s why I love to demo the Cold Cork in person.”

For a couple that met at a bar one night in downtown Houston, the Cold Cork is almost a poetic destination as a business endeavor and one that they both really relish.

“We both have our strengths, and we give each other a lot of support,” says Michelle.

“I’m very mechanically inclined, so I develop and invent, and Michelle is great with the marketing aspect and working with people to purchase the product,” adds Tyler. “In addition to the Cold Cork, we do have a couple of early projects that we are working on. I think there is a lot of opportunity with our technology to take what we have learned and fit that into different product lineups moving forward.”

Houston fashionista fuels fresh brands with pitch series

After growing her audience to over a million followers on Instagram, Houston fashion blogger Dede Raad felt the pressure to expand her business — but she didn't feel inspired by any particular line of business to grow into.

"In the blogging world, which I've been doing for about seven years, everyone's next step is to start a brand and to start something of their own," Raad, founder of Dress Up Buttercup, tells InnovationMap. "I just don't have anything in my heart that I was really passionate about. I know once you start something, you have to give it your all."

But what Raad realized — after a year of thinking about her next move and a chance viewing of Shark Tank — was that tons of business founders were passionate about their own brands, and there was an opportunity for Raad use her community to support them instead of coming up with something of her own.

She put the call out to her followers to find founders with growing brands. Raad launched "Build Up Buttercup," an initiative that featured small business pitches for a select group of investors, with her husband, Ted. The event, which happened last October, resulted in eight business pitches across four episodes uploaded to Dress Up Buttercup's page that garnered hundreds of thousands of views. The initiative also resulted in a handful of investments and cash prizes.

"It was a crazy four days, but it was so cool to see the brands and the passion behind it and for Ted and I to help in both a financial and advising way," Raad says.

Raad was joined at the event with fellow investors, which included Houston-based investment firms Curate Capital and Trend Ventures, the investment arm of influencer management company Trend Management, founded by Ted Raad.

Of the eight that pitched, four companies received investments. Dress Up Buttercup invested in Houston-based jewelry company Burdlife and children's clothing brand Poppy Kids. Trend Ventures made investments in Cold Cork and Houston-based tech startup, AIM7, which closed its seed round in December.

Raad tells InnovationMap that she'd be interested in hosting another edition of "Build Up Buttercup" in the future, but for now she's focused on her two new brands. Her role within both of the companies is very hands on, she explains, and meets with the founders at least once a week. She also markets both brands to her Instagram community.

"We're not just sending you a check — we want to be involved," Raad says. "I've worked with brands for the past seven years, and I've seen what people are buying. I have such a power in my community, and I know what they like."

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.
