It's an Italian invasion in Houston — and it's happening in the name of accelerating innovation within aerospace.

For the first time, Italy has announced an international aerospace-focused program in the United States. The Italian Trade Agency and Italian Space Agency will partner with Space Foundation to launch Space It Up, an initiative that will accelerate six companies in Houston.

“The launch of Space It Up marks a pivotal moment in our ongoing commitment to nurturing innovation and facilitating global partnerships," Fabrizio Giustarini, Italian Trade Commissioner of Houston, says in a news release. "This program serves as a testament to the collaborative spirit that defines the aerospace industry. It represents the convergence of Italian ingenuity and Houston's esteemed legacy in space exploration, setting the stage for unprecedented advancements."

The Italian companies in the inaugural cohort represent various areas of cutting-edge aerospace innovations and technologies. The selected companies are:

  • Arca Dynamics, a space traffic management and Earth observation service provider.
  • Delta Space, a low-cost satellite connectivity for sensors and launch services.
  • Involve Space, a pseudo-satellite platform and intelligent software to enable access to space.
  • Nabu, an IoT and data analysis provider.
  • NOVAC, which is producing an innovative shapeable all-solid-state structural supercapacitor.
  • T4i, developing innovative engines to serve small satellite platforms.

ITA and Space Foundation will provide a six-week immersive program focused on the most important aspects of the aerospace industry that will also include business events, networking opportunities, and, ultimately, connect the Houston aerospace community with the Italian startups.

Space It Up will launch its kick-off event at noon on September 1 at Ion Houston, followed by a demo day on September 27. The Demo Day will demonstrate the transformative impact on the aerospace industry by presenting the progress on break-through technologies and projects like the acceleration programs.

The Houston office is one of five ITA offices in the U.S. Other partnerships include Houston-based digital platform leader Village Insights, which will serve as a digital epicenter for Italy’s aerospace companies.

“From the cradle of Renaissance to the frontiers of the cosmos, Italy’s heritage of space innovations knows no bounds,” Keli Kedis Ogborn, Space Foundation vice president of space and entrepreneurship, says in a news release. “With a legacy of scientific advancements, Italy continues to script a new chapter in history, this time with a broader focus on international collaboration and impactful growth to the evolving global space ecosystem.”

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.
