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.”

Houston startups closed $1.75 billion in 2025 VC funding, says report

by the numbers

Going against national trends, Houston-area startups raised 7 percent less venture capital last year than they did in 2024, according to the new PitchBook-NVCA Venture Monitor report.

The report shows local startups collected $1.75 billion in venture capital in 2025, down from $1.89 billion the previous year.

Houston-based geothermal energy company Fervo Energy received a big chunk of the region’s VC funding last year. Altogether, the startup snagged $562 million in investments, as well as a $60 million extension of an existing loan and $45.6 million in debt financing. The bulk of the 2025 haul was a $462 million Series E round.

In the fourth quarter of last year, Houston-area VC funding totaled $627.68 million. That was a 22 percent drop from $765.03 million during the same period in 2024. Still, the Q4 total was the biggest quarterly total in 2025.

Across the country, startups picked up $339.4 trillion in VC funding last year, a 59 percent increase from $213.2 trillion in 2024, according to the report. Over the last 10 years, only the VC total in 2021 ($358.2 trillion) surpassed the total from 2025.

Nationwide, startups in the artificial intelligence and machine learning sector accounted for the biggest share of VC funding (65.4 percent) in 2025, followed by software-as-a-service (SaaS), big data, manufacturing, life sciences and healthtech, according to the report.

“Despite an overall lack of new fundraising and a liquidity market that did not shape up as hoped in 2025, deal activity has begun a phase of regrowth, with deal count estimates showing increases at each stage, and deal value, though concentrated in a small number of deals, falling just [8 percent] short of the 2021 figure,” the report reads.

Sandbox VR brings new gaming center to Houston's tech-savvy population

Get In The Game

Sandbox VR, a futuristic, full-body virtual reality gaming experience, has announced it will enter the Houston market this month, opening its first local gaming center on January 23.

"Houston's reputation as a hub for innovation and technology makes it a perfect fit for Sandbox VR," said Steve Zhao, CEO and founder of Sandbox VR, in a statement. "The city's diverse, tech-savvy population and strong entertainment culture create an ideal environment for our immersive VR experiences. LOL Entertainment continues to exceed our expectations as a partner, and we're excited to bring our cutting-edge virtual reality gaming to Texas's largest city."

The new gaming center opens Friday, January 23 at 797 Sorella Court in CityCentre.

One of the games that stands out is the Stranger Things: Catalyst game, based on the blockbuster Netflix television series. Groups of one to six players will be dropped into the sinister Hawkins Lab and the mysterious Upside Down to fight Demogorgons and other monsters. The game features Matthew Modine reprising his role as Dr. Martin "Papa" Brenner, who imbues players with psychic powers.

Other games include the supernatural pirate title The Curse of Davy Jones and other Netflix tie-ins based on Zack Snyder's Rebel Moon and Squid Game. Sandbox VR offers fully-immersive group play activities that range from combat to puzzle solving for a variety of age groups.

The opening of Sandbox VR is another part of the expansion of LOL Entertainment, who touts itself as one of the pre-eminent hosts of immersive and gaming experiences in the U.S. Sandbox VR will be their first entry into the Houston market, with another immersive group adventure game, Time Mission, set to open at the the Marq'E Entertainment District later this year.

“Bringing Sandbox VR to CityCentre Houston is a big milestone for LOL Entertainment, for Sandbox VR, and for this market,” said Rob Cooper, CEO of LOL Entertainment. “Houston is a fast-growing, experience-driven city, and we’re excited to give locals and visitors a truly immersive, social gaming destination that you can’t replicate anywhere.”

Presale tickets for the grand opening of Sandbox VR are available here. Standard pricing is $55-$65 per event, but Sandbox VR is running a special for 30 percent off with code OPEN30 for those who purchase before Thursday, January 22. Presale buyers are also entered into a drawing for free Sandbox VR for one year.
