After seeing through an exit of his first startup NextSeed, lawyer-turned-entrepreneur Youngro Lee took on a leadership role at the acquiring company, Republic. But his fintech innovation wheels kept turning.

"Brassica is, I personally consider, an extension and a national evolution of my original starting point," Lee says on the Houston Innovators Podcast, "which is basically to democratize finance so that everyone can have access to alternative assets as part of their wealth management investments or even for pleasure to just be able to invest in things they believe in."

Brassica Technologies Inc. is a fintech infrastructure company that's providing a platform for alternative assets, Lee explains. While investments in the public markets have platforms already, there are other investment opportunities that are managed in a less optimized way for investors.

Lee says there hasn't been a seamless solution created for the backend of these transactions, things like custody of those assets or transferring and keeping track of them.

"The reason why I thought this was what I wanted to focus on next was exactly because it was an issue I struggled with as a founder of NextSeed," Lee says on the show. "The backend was always an issue. There's not one single vendor that we felt really understood our business, was doing it efficiently, or enabled us to deliver those services to our end clients."

Lee says he has been working on addressing this gap in the market for the past two years under his role at Republic. After holding an executive position at the company as a whole, he currently oversees the Asian market as general partner of Republic Asia.

"We didn't know where this process was going to go. It was a corporate initiative to try to understand what the market needs — because we needed it," Lee says. "We quickly realized that this idea can be really big. Once we had that conclusion, that the problem we're trying to solve and the opportunity that the market presents is significant enough, we knew Brassica deserves to be its own company."

Shortly after that, Lee started reaching out to potential investors and raised an $8 million seed round to take the company out of stealth last month. Houston-based Mercury Fund led the round, with participation from Valor Equity Partners, Long Journey Ventures, NGC Fund, Neowiz, Broadhaven Ventures, Armyn Capital, VC3DAO, Alpha Asset Management (Korea), and other global FinTech investors participated in the round.

Lee shares more about the future of Brassica, including the challenges he's facing within regulation and the state of fintech as a whole, on the podcast. He also weighs in on how he's seen the Houston innovation ecosystem grow and develop alongside his own entrepreneurial journey.

Houston-founded blockchain startup raises $15M series A to increase international impact

money moves

A blockchain technology company that was founded out of Rice University has closed its latest round of funding.

Founded in 2017, Topl is a blockchain-as-a-service company that's developing a purpose-built blockchain ecosystem to empower impact and sustainability within its userbase of businesses. The company's $15 million series A round was co-led by Houston-based Mercury, Republic Asia, and Malta-based Cryptology Asset Group.

“Topl’s blockchain was purpose built to power the next wave of supply chains and markets, that are more sustainable and inclusive,” says Chris Georgen, founder and managing director of Topl, in a news release. “Every decision we’ve made has been relentlessly focused on this problem and it’s exciting to see this approach yielding results with more than 30 different impact-forward use cases already live or approaching launch. Through this latest fundraise and with the strong network we’ve built, we’re looking to accelerate the growth of our ecosystem and setting a goal of at least 100 applications launched by next year.”

The company, which is now headquartered in Austin but still has a presence in Houston, has raised over $20 million in investment to date. Topl announced its $3 million seed round of funding — also led by Mercury — in 2020.

“Despite broader market dynamics across the Web3 sector, Topl’s strategic and early focus on users allowed the team to build an incredibly strong foundation that can weather cycles by providing an increasingly in-demand service to companies implementing various sustainable initiatives,” says Samantha Lewis, principal at Mercury, in the release. “We are excited to support Topl in this pivotal growth period.”

The round included two new international investors in Topl. Republic Asia is a newly launched arm of private investing platform Republic that is focused on fintech and web3 solutions. Houstonian Youngro Lee leads the division as executive vice president at Republic and head of Republic Asia and will join Topl's board to assist with international expansion.

“Sustainability and climate considerations are no longer mere luxuries, but an absolute necessity for companies to contribute to global finance and commerce,” Lee says in the release. “Topl will make it easier than ever for any organization around the world to harness the power of blockchain to track and monetize their positive environmental impact.”

Cryptology, with its European operations, also brings Topl key international presence.

"It's been an honor to see Topl progress from when it first entered Iconic Lab's accelerator program back in 2018 to where it is today," says Patrick Lowry, CEO of Cryptology, in the release. "Cryptology is hyper-focused on driving crypto adoption in an impact-focused, sustainable manner. We are proud to add Topl to our portfolio of companies and excitedly await Topl's network decentralization."

In addition to increasing its international impact, Topl will reportedly continue to build out its blockchain and technology. Per the release, Topl expects to launch a traceability platform for ethically and sustainably sourced products later this year.

Topl, which launched a grant program to fund Web3 startups and developers with inclusive and sustainable solutions, plans to announce its first 20 grant awards early next year. The grant recipients will also receive development, go-to-market, and fundraising support from Topl's team and network.

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.
