Houstonians Molly Voorhees and Christina Milligan have officially launched a line of hand sanitizing and surface cleaning products that blend the importance of cleanliness and safety with the added value of accessibility and a refined appearance.

The products make up the entrepreneurs' new brand, Cobalt, that Voorhees, president of Beck's Prime, and Milligan, an organizing and style expert, first conceptualized in March. As working parents of young children, the two women wanted to create a line of sanitizing products that boosted their confidence in the safety of their environments amid a pandemic and that they'd be proud to pull out of their purse on short notice.

"Cleaning products are in your bathroom or are in an ugly looking bottle or the back of our restaurant in massive chemical containers. There is really nothing for the on-the-go market," Voorhees says.

Too, the women didn't want to stop at hand sanitizer. Instead, they sought to encourage and educate clientele on the importance of cleaning high-touch surfaces, like phones, steering wheels, sunglasses, and the likes.

"It really resonated with us that your hands are only as clean as the surfaces that you touch," Milligan says. "We wanted it to be very approachable and easy to understand and also discrete. We didn't want anyone to feel ashamed if they pulled out a bottle of Lysol on a table."

The result was six FDA-approved sanitizers, sprays, keychains, and to-go kits that eliminate 99.9 percent of bacteria and viruses in easy to access, personal-sized, contemporary bottles, ranging from $14 to $30. The products are designed to be free of harsh, alcoholic odors and come in scents like peppermint and bubble gum.

Each item in the line boasts sleek, trendy designs in a cool blue hue. And while they look quite polished today, bringing the line to launch started off as a somewhat messy process.

"We kinda thought it would be easy. We would just put cleaner in a 4-ounce bottle and that would be fine," Milligan says.

But due to the high demand for chemical products in the pandemic and the way that industrial filling lines are set up, producing cleaning products in personal-sized bottles proved difficult. The women, who became known as the "the girls who want to put cleaner in their purse," were initially met with a resounding "no" from large chemical corporations.

However, by the summer the duo was able to make more headway. They were nearing production with a chemical partner when they learned of a local business who could produce their product by hand all within the Bayou City.

"It turned out through a connection we were making with labels that we discovered [William Price Distilling Company] that was right in our backyard in Houston that was newly filling bottles," Milligan says. "They were employing out of work restaurant staff. Molly and I both felt really strongly about that."

Voorhees and Milligan quickly partnered up with the Garden Oaks-Oak Forest distillery and have since produced roughly 2,500 units of their various products.

In fact, the line is decidedly Houston-based. In addition to William Price, Cobalt was also created with the help of Houston Labels for design. Deutser helped the team from a business management perspective. And the custom scents were developed by Clarity Fragrance near Memorial City.

As of press time, the products are available for purchase online and in area boutiques, including Emerson Sloan, Lexington Boutique, Zadok Jewelers, Therapy Hair Studio, and The Chocolate Bar. They aim to expand to more stores and markets and adapt the line based on demand.

"We feel so fortunate that we have a variety of products," Voorhees says. "It's always my belief that the consumer will tell you what they want and you go in that direction."

Houston coffee startup pivots to hand sanitizing product amid pandemic

Houstonians' workday routines look much different today than they did seven months ago. With a large percentage of people working from home, office rituals have come to a halt and few habits have been immune to change — including our coffee consumption.

In early March, Constantine Zotos and Mitchell Webber already knew this didn't mean good things for their local nitro coffee company, Recharge Brewing Co. Though the brand had grown steadily over the better course of two years, the duo had focused their business on installing and supplying their nitro coffee taps to two of the most taboo markets at the time: office spaces and restaurants.The duo aptly predicted that the demand for their product would soon dry up and quickly shifted their operations to focus on a product that was considered a necessity: hand sanitizer.

To get started, the young entrepreneurs and their small team of six began cold calling down a list of Purell distributors they found online. They soon found that many businesses could hardly keep the product in stock.

"They asked us if they could fly a jet down to pick up the hand sanitizer themselves," Zottos says of one distributor. "I told them not to get ahead of themselves, but it just speaks to the sense of urgency everyone had."

The team studied up on the basic ingredients of hand sanitizer to make the liquid, alcohol-based form that infiltrated the market in the first few weeks of the pandemic. At the time there was such a rush for the product, and such a low supply of the material needed to make it, that the team resorted to selling the product without traditional pump tops or plastic caps. Instead they used the slow release plastic pourers that are often used on liquor bottles.

Still, they were focused on doing it right. In addition to the long hours spend to get the product out the door, Zotos and Webber took special care to ensure that their sanitizer met all FDA and EPA requirements by working with consultants and lawyers, as well as reading up on all the pertinent documents and literature between sleeping shifts and time on the shop floor.

"We took the stance that we would rather rush toward compliance rather than run from it," Zotos says.

It didn't seem to slow down the demand. One week in they formed Modern Chemical, and by the middle of the month the company was fulfilling substantial orders with a team of 40 employees. By the summer, Modern Chemical released a gel-based, FDA-registered sanitizer that got them in with giant B2B clients, such as the Massachusetts Bay Transit Authority, Jefferson Parish School District, and recently the City of Austin.

The pair agrees that their background with Recharge gave them a leg up in the beginning.

"Knowing the pumps and hoses and all the stuff you really need to run a bottle facility and a hand sanitizer facility, we already had," Webber says. "On top of that when all this started, there were some long days and long nights, but being in the nitro coffee business, we were used to long hours. It prepared us for this huge push for the drastic demand that needed to be filled."

Location and timing also played a huge role in their success, Zotos adds. "When the pandemic struck we were able to bring on a lot of people who are extraordinarily talented throughout the company. If we weren't hiring in the pandemic environment like this I think we would be hard pressed to find people as talented as we did as quickly as we did," he says. "And Houston really played a big part in that."

Today, the company of about 60 employees is producing about 15,000 gallons of hand sanitizer per day and is in the process of launching disinfectant wipes and spray. They recently moved all of the Modern Chemical operations into a new and improved facility off Air Tec and Interstate 45 that will allow for more efficient packaging and loading of products and — in another pivot — are even offering custom labeling, scenting and color dyes, plus specialty dispensing stands for their product.

"Neither of us have a chemical background and we are not ignorant to that. But we know how the equipment works from an operational side of things and if we can make the packaging look the best. If we can package the most for the best price then people are going to want to buy it," Zotos says. "Instead of taking the let's do everything route, we found our niche in the chemical supply chain, which is packaging."

And as Modern Chemical continues to settle into its new space and eventually a post-pandemic market, Zotos and Webber plan to revisit and revamp Recharge Brewing with the lessons they've learned. The duo plans to use their original facilities to help other small business owners launch and produce beverage brands of their own by early 2021.

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.

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.
