Conroe-based construction tech company that specializes in creating technology to develop cost-efficient high-quality homes built in half the time is gearing up for new growth due to their recent selection as a finalist in SXSW Pitch 2020.

3Space Makers was at first selected as an alternate in the "Artificial Intelligence, Robotics & Voice" category for the 12th annual SXSW Pitch, formerly known as SXSW Accelerator, but was recently bumped to finalist.

"It's gratifying to learn that we have been selected," Ted Cox, CEO and co-founder of 3Space Makers, tells InnovationMap. "Our team has been working really hard for this moment. I think that not only do we have a good product, but the mission that we are on is what is resonating the most."

3Space Makers uses robotics, artificial intelligence, and 3D printing to spur innovation in the construction industry, allowing for faster manufacturing processes which, according to Cox, will enable homes to be built better, faster, and cheaper. The typical 3Space Makers home takes one month to build, drastically reducing the time frame of construction projects and thus reducing their cost.

"Everything in the construction industry right now is manual and human-driven," says Cox. "Until now that has been enough to get the job done. A typical home currently takes 3 to 6 months to build, 3Space Makers dramatically takes the inefficiencies out of the construction industry."

The company is developing new innovative technology marrying autonomous robotics and cloud-based control systems to produce detailed data to validate building standards. Their Fab & Fill process uses eco-friendly material known as BioSilicate to manufacture complete metal-framed walls and roofs using semi-automated processes.

The eco-friendly material can be made from natural materials native for particular regions such as corn husks and sugar cane, converting waste material into revenue for local farmers.

"We are building homes that are safe, durable, and affordable to those who are most in need using our processes," says Cox "We can cut the time of construction in about half along with the cost, that makes homes available for those who couldn't afford it otherwise, it's a bringing the promise of technology to the construction industry."

The idea for 3Space Makers was born out of the need to help vulnerable members of society, including low-income families and homeless veterans who cannot afford to buy a home with current high real estate prices.

The construction start-up aims to meet its '50/50/50' performance target to benefit veterans and low-income families.

"Any technology or process we develop," says Cox. "Must be 50 percent faster, 50 percent less expensive and 50 percent better than current methods on the market."

At their SXSW pitch, 3Space Makers will premiere as Integra Homes, a rebrand that represents a focus on increasing affordability for homes. The company is also currently working on raising a round of funding this year, along with gearing up to grow their facilities to finish their current projects, including building 5,000 homes in the U.S. and Jamaica.

"When we were originally founded, our focus was on serving homeless veterans, that remains to this day," says Cox. "But we also found that there is quite a need, not only in the U.S. for affordable homes. By being able to come in and build high-quality affordable homes with the help of our technological processes, it's going to make a big difference for many individuals."

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.”
