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

money moves

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."

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.
