In the not-too-distant future, a Texas company's 3-D printed homes will be popping up across the world for a fraction of the cost of traditional homes.

"It's our mission at ICON to reimagine the approach to homebuilding and construction and make affordable, dignified housing available to everyone throughout the world," says Jason Ballard, co-founder and CEO of Austin-based ICON LLC. "We're in the middle of a global housing crisis, and making old approaches a little better is not solving the problem."

The 3-D printed homes startup just raked in $9 million in seed funding from a host of investors, including Fort Worth-based homebuilding giant D.R. Horton; Vulcan Capital, a Seattle investment firm launched by Microsoft billionaire Paul Allen, who died October 15; Austin startup accelerator Capital Factory; Austin real estate developer Cielo Property Group; and San Francisco venture capital firm Oakhouse Partners, which is the lead investor.

At this point, ICON executives aren't sure when their homes will be popping up around town. However, Ballard tells CultureMap, "serious conversations" are underway about bringing these homes to Austin and other places around the world.

In March, ICON reaped tons of press when it unveiled a 350-square-foot 3-D home at SXSW — the first home of its kind to receive a construction permit in the U.S. At the time, ICON executives said the home — constructed of concrete and printed in less than 48 hours by 3-D printing robots — cost less than $10,000. By contrast, the median price in September 2018 of a single-family home in the Austin metro area was $302,250.

ICON's first batch of homes is planned for a project in impoverished El Salvador that's being developed in conjunction with New Story, a San Francisco nonprofit that seeks to eradicate homelessness. The first homes there are scheduled to be printed next year.

ICON is targeting a per-home cost of $4,000 in El Salvador. Relying on technology upgrades, ICON hopes to create each 3-D home in less than 24 hours.

"While prices to print homes will vary from country to country and state to state," Ballard says, "the big takeaway is that downloading and printing a home has the potential to cost half of standard construction costs."

Homes at the development in El Salvador will measure 600 to 800 square feet — around the size of a typical one-bedroom apartment. Eventually, ICON aims to print homes in the 1,500- to 2,000-square-foot range.

Among the advantages of 3-D printed homes cited by ICON are:

  • Speedy construction
  • No manual labor
  • Little generation of leftover construction materials
  • "Tremendous" design freedom

There's a positive environmental impact with this construction process as well.

"Conventional construction is slow, fragmented, wasteful, and has poor thermal properties that increase energy use, increase operating costs, and decrease comfort," Ballard says. "Also, conventional materials like drywall and particleboard are some of the least resilient materials ever invented."

winner, winners

Rice University student-founded companies took home a total of $115,000 in equity-free funding at the annual Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge last week.

2025 Rice Innovation Fellow Alexandria Carter won the top prize and $50,000 for her startup Bionostic. The startup offers personalized diagnostics for cancer patients by using 3D culturing through its Advanced Tumor Landscape Analysis System (ATLAS) platform.

Carter is working toward her PhD in bioengineering in Professor Michael King's laboratory. She recently completed the Rice Innovation Fellows program and plans to commercialize ATLAS, according to a news release from Rice.

Actile Technologies, founded by another former Rice Innovation Fellow, Barclay Jumet, won second place and $25,000. The company is developing and commercializing textile-integrated technologies. InnovationMap first covered Jumet's wearable technology back in 2023.

Kairos took home the third-place prize and $15,000, plus the $2,000 audience choice award and the $5,000 undergraduate business award. Founded last year by Sanjana Kavula and Adhira Tippur, Kairos is an AI-powered patient intake platform built specifically for independent dental practices.

The NRLC features top startups founded by undergraduate, graduate and MBA students at Rice each year. The top three finishers were named among a group of five finalists earlier this year, which also included HAAST Autonomous and Project Kestrel.

HAAST is developing an unmanned aircraft for organ transport, while Kestrel uses machine learning to organize bird photographers’ photo collections.

Teams presented multiple five-minute pitches throughout the application process over Zoom and in-person before the five finalists presented at the NRLC Championships April 21 at the Rice Memorial Center. Each finalist walked away with an equity-free investment.

Houston-based, NASA-founded cleantech startup closes $12M seed round

Fresh Funds

Houston-based Helix Earth Technologies has closed a $12 million Seed 2 funding round to scale manufacturing of its energy-efficient commercial HVAC add-on technology.

Veriten, a Houston-based energy investment firm, led the round. Rua Ventures, Carnrite Ventures, Skywriter LLC and Textbook Ventures also participated.

Helix Earth—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—is developing high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial HVAC units. The company reports that its technology can lead to "healthier indoor air, lower energy bills, reduced building maintenance, and more comfortable spaces for building owners and occupants."

"Building owners are dealing with rising energy costs, uncontrolled humidity, and aging infrastructure with no viable, cost-effective path forward. We are in the field today solving these problems for commercial customers, and this capital puts us on an aggressive path to scale,” Rawand Rasheed, Helix Earth co-founder and CEO, said in a news release.

“The strength of this round reinforces our team's conviction that we can transform innovation-starved sectors with transformational solutions that deliver order-of-magnitude improvements to owners and operators, for both their bottom line and the environment,” Rasheed added.

Maynard Holt, Veriten’s founder and CEO, said that the investment firm is tripling its investment in Helix Earth.

"The team has built breakthrough technology with real applicability across multiple industries,” Holt said in the release. “Their first product will have an immediate and measurable impact on our energy system, and they are already pursuing adjacent innovations to help heavy industries operate more efficiently and with less waste. This is a well-rounded team with a proven track record of strong execution and disciplined capital management.”

Helix Earth also closed a $5.6 million seed funding round in 2024, led by Veriten.

Last year, the company secured a $1.2 million Small Business Innovation Research (SBIR) Phase II grant and won in the Smart Cities, Transportation & Sustainability contest at the 2025 SXSW Pitch Showcase. Rasheed was also named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

Texas earns 22nd 'best state for business' title as GDP hits $2.9T

booming economy

The Texas business sector recently received a double dose of good news.

For the 22nd consecutive year, Chief Executive magazine named Texas the best state for business. In tandem with that achievement, preliminary new estimates from the U.S. Bureau of Economic Analysis show the size of Texas’ economy jumped to $2.9 trillion in 2025, up by a nation-leading growth rate of 2.5 percent compared with the previous year.

Speaking about the Chief Executive honor, Gov. Greg Abbott says Texas benefits from pro-growth policies, a strong workforce, strategic investments in education, training for high-demand skills and the presence of critical infrastructure.

“Texas is where businesses innovate and where opportunity abounds. … We will continue to move at the speed of business as we build a more prosperous Texas for generations to come,” the governor says.

An annual Chief Executive survey of CEOs, presidents and business owners determines which state is the best for business. Texas has landed at No. 1 every year since Chief Executive launched the ranking.

“Truly, this is an incredible run that Texas has going,” says Christopher Chalk, publisher of Chief Executive. “CEOs are a tough group to please, and yet year after year Texas continues to earn the top spot—no small feat.”

It’s also no small feat for a state to notch annual gains in its gross domestic product (GDP), a measurement of economic power based on the value of goods and services produced each year.

With an estimated GDP of $2.9 trillion last year, Texas maintains its position as the eighth-largest global economy compared with the nations of the world, based on preliminary estimates from the International Monetary Fund.

In reference to Texas’ GDP growth, Abbott says the Lone Star State is “the premier destination for job creators from across the country and world. We will keep attracting world-class investment, create jobs, and expand opportunity for Texans for generations to come.”
