For the second time in less than six years, Houston entrepreneur Allie Danziger has navigated a company through an exit. But, with the two exists under her belt, Danziger says the two transactions could not be any more different.

Danziger founded Integrate Agency, a digital-focused public relations firm, in 2009 and sold it to another marketing and PR firm based in Austin in 2018. She founded her next company, Ampersand Professionals, in 2020 to address the challenges for upskilling young professionals to prepare them for success in the workplace — something employers really wanted, but struggled to do consistently.

Last month, Ampersand was acquired by Ascent Funding, a college loan provider that's building out a platform to support its college-aged borrowers. In this week's episode of the Houston Innovators Podcast, Danziger shares how this opportunity came about and looks back on these two pivotal deals. Read more.

Houston has another unicorn — a company valued at $1 billion or more — thanks to a recent round of funding.

Axiom Space released the news this week that it's closed its series C round of funding to the tune of $350 million. While the company didn't release its valuation, it confirmed to Bloomberg that it's over the $1 billion threshold. Axiom reports that, according to available data, it's now raised the second-most funding of any private space company in 2023 behind SpaceX.

Saudi Arabia-based Aljazira Capital and South Korea-based Boryung Co. led the round. To date, Axiom has raised over $505 million with $2.2 billion in customer contracts, according to the company.

“We are honored to team with investors like Aljazira Capital, Boryung and others, who are committed to realizing the Axiom Space vision,” Axiom Space CEO and president Michael Suffredini says in a news release. “Together, we are working to serve innovators in medicine, materials science, and on-orbit infrastructure who represent billions of dollars in demand over the coming decade.

"We are building on the legacy of the International Space Station, leveraging the pillars that were constructed in low-Earth orbit more than two decades ago, to now support a burgeoning global space economy,” he continues.

Axiom, founded in 2016 by Suffredini and Executive Chairman Kam Ghaffarian, is working on the first commercial space station that will replace the International Space Station when NASA retires it in 2031. The first module is expected to launch to the ISS by 2026.

Boryung, which has reportedly invested in Axiom prior to this round, is a firm focused on health care investments. Chairman of the firm, Jay Kim, says Boryung is making investments in technology that supports human space missions and building a space health care system.

“We recognize the depth of human spaceflight knowledge and the level of space station construction and management experience at Axiom Space, as well as the sophistication of the company’s sales and business strategy,” Kim says in the release. “We have a shared vision and ethos and are excited to build opportunity together.”

Naif AlMesned, CEO and managing director of Aljazira Capital, says his investment in Axiom is in accordance with Saudi Vision 2030, a government program launched in 2016 by the Kingdom of Saudi Arabia to increase economic, cultural, and social diversification for the sovereign state.

“We believe in the importance of innovation in various sectors and across various markets," AlMesned says in the release. "In line with the Saudi Vision 2030’s transformative approach, we acknowledge the need for technology toward the advancement of human life. To that end, we are excited to support Axiom Space along its journey of building for beyond.”

In addition to its work on Axiom Station, the company is working on other contracts with NASA, including constructing a new age spacesuit, a long-term NASA contract that's reported to be $1.26 billion. Axiom has also collaborated with NASA on two private astronaut missions — with two more planned for 2024.

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Texas ranks among top 10 best states for jobs in new report

jobs report

Business boosters often describe Texas as an economic engine. A new ranking from personal finance website WalletHub underscores that assessment.

WalletHub put Texas at No. 8 on its new list of the best states for jobs. Nebraska grabbed the No. 1 spot, and West Virginia landed at No. 50.

To compile the list, WalletHub evaluated 34 metrics from two categories: job market and economic environment. It then crunched the numbers to create a score for each state. A score of 100 represents the most favorable conditions for job seekers.

Texas ranked 25th in the job market category and second in the economic environment category. Texas’ eighth-place showing was based on a score of 59.23.

“The best states for jobs make it easier for residents to find and retain jobs, and employers in these states also offer very competitive compensation and benefits,” WalletHub analyst Chip Lupo said. “In addition, the top states are great places for people looking to raise a family, ranking among the best states for working parents.”

Data released in late October shows Texas led all states for job growth during the 12-month period that ended in September. In that time, Texas added 154,300 jobs at an annual rate of 1.1 percent.

“Texas is America’s jobs leader,” Gov. Greg Abbott said in a press release. “Businesses big and small invest with confidence in Texas and in our growing and skilled workforce. That means bigger paychecks for more Texans and more opportunities for Texas families to prosper for years to come.”

Abbott noted Texas reigns as the top state for attracting job-producing businesses and creating jobs at small businesses.

The Houston metro area actually saw a decline in new jobs in September, losing 7,300 jobs compared with the previous month. On a year-over-year basis, the region added 13,500 jobs, with professional and business services, construction, and private education and health services leading the growth.
