Houston software startup raises $12.5M series B

money moves

Houston-based Codenotary, whose technology helps secure software supply chains, has raised $12.5 million in a series B round. Investors in the round include Swiss venture capital firm Bluwat and French venture capital firm Elaia.

The $12.5 million round follows a series A round that was announced in 2020, with total funding now at $18 million.

Codenotary, formely known as vChain, says the fresh round of money will be used to accelerate product development, and expand marketing and sales worldwide. Today, the startup has 100-plus customers, including some of the world’s largest banks.

Codenotary’s co-founders are CEO Moshe Bar and CTO Dennis Zimmer. They started the company in 2018.

Bar co-founded Qumranet, which developed the Linux KVM hypervisor. A hypervisor creates and runs virtual machines. Software provider Red Hat purchased Qumranet in 2008 for $127 million. Before that, he founded hypervisor company XenSource, which cloud computing company Citrix Systems bought in 2007 for $500 million.

“Codenotary offers a solution which allows organizations to quickly identify and track all components in their DevOps cycle and therefore restore trust and integrity in all their myriad applications,” Pascal Blum, senior partner at Bluwat, says in a news release.

The SolarWinds software supply chain hack in 2020 and the more recent emergence of Log4j vulnerabilities have brought the dangers of software lifecycle attacks to the forefront, Bar says. Now, he says, more and more companies are looking for ways to prove the legitimacy of the software that they produce.

Codenotary is the primary contributor to immudb, the an open-source, enterprise-class database with data immutability, or stability, designed to meet the demands of highly used applications.

money moves

A Houston tech company that has optimizes a notarization system for coding professionals has closed a multimillion-dollar round of funding.

Houston-based vChain, which created the CodeNotary Open Source code trust solution, has raised $7 million in a series A funding round. Paris-based Elaia Partners led the investment round, and other contributors include Zug, Switzerland-based Bluwat and Seattle-based Acequia Capital.

"CodeNotary today processes over 9 million code and container authentications every single month," says CEO Moshe Bar in a news release. "We believe this is proof that the market demands secure and simple to use trust solutions for the modern DevOps environment."

Bar, who previously founded of XenSource and Qumranet, co-founded vChain with Dennis Zimmer in late 2018. The company released its first product in April of last year, and has a secondary office in Amsterdam.

"With much more at stake both financially and reputationally, companies must act quickly to bring trust and security into their DevOps process," Bar continues. "CodeNotary was created to solve this issue and ensure that only trusted code and data run in production."

The software tool, which is used to ensure code is securely transmitted throughout the entire development to production process, has several platform integrations and works with languages such as JavaScript, Python, Go, Java, and more.

"Our vision is a digital world where every object has a globally unique and meaningful identity," says Zimmer, who serves as CTO, in the release. "For the first time, DevOps teams can completely secure the integrity of their Continuous Integration and Continuous Delivery pipelines. Not just internally, but also across companies, contributors and contractors."

The money raised will be used to continue the development of the tool as the DevOps industry continues to grow within the market.

"The DevOps industry is a rapidly growing billion-dollar market transforming itself very quickly," says Marc Rougier, partner at Elaia, in the release. "The importance of DevOps for any organization is obvious, no matter its size. However, the main reason for hesitation in DevOps transformation is a lack of trust. vChain is the leading solution to bring trust to DevOps and we're thrilled to be a part of it."

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.
