Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from adtech to aerospace — recently making headlines in Houston innovation.

Houston-based Direct Digital Holdings, an adtech platform, is celebrating one year after its IPO. Co-Founder Mark Walker shares on the Houston Innovators Platform how he took this experience in tech, advertising, and media to create his company's platform.

He also shared the story of how Direct Digital went public. Walker says the decision to IPO made the most sense for his company — though it wasn't an easy process. Direct Digital is only the ninth company founded by a Black entrepreneur to go public on a US stock exchange.

"If you think the process is hard — it actually is," Walker says on the journey to IPO. "We were a privately held company, and we knew we had a good growth trajectory and we looked a couple different options. We decided to go public in a very traditional way." Read more.

Intuitive Machines, a space tech company based in Southeast Houston, announced that it has completed the transaction to merge with Inflection Point Acquisition Corp., a special purpose acquisition company traded on Nasdaq.

“We are excited to begin this new chapter as a publicly traded company,” says Steve Altemus, co-founder, president, and CEO of Intuitive Machines, in a news release. “Intuitive Machines is in a leading position to replace footprints with a foothold in the development of lunar space. With our launch into the public sphere through Inflection Point, we have reached new heights financially and opened the doors for even greater exploration and innovation for the progress of humanity.”

The transaction, which was originally announced in September, was approved by Inflection Point’s shareholders in a general meeting on February 8. As a result of the deal, the company will receive around $55 million of committed capital from an affiliate of its sponsor and company founders, the release states. Read more.

Umbrage, founded in 2019, is proving once again that Space City is a software hub. Earlier this month, Founder Will Womble announced that Umbrage has been acquired by Bain & Company.

Umbrage creates custom software for companies by partnering with an internal technology team that makes the products. It’s a “teach a man to fish” method that has brought the company great success in creating software such as Shell’s TapUp app.

Bain & Company works with clients in 64 cities across 39 countries, meaning the global consultancy is positioned to bring Umbrage worldwide.

"Alongside Bain, we can deliver enhanced end-to-end solutions that will position our clients for success and to adapt during waves of disruptive emerging technologies," says CEO Womble in the release. Read more.

A Houston software company is celebrating an exit this month.

Umbrage, founded in 2019, is proving once again that Space City is a software hub. Earlier this month, Founder Will Womble announced that Umbrage has been acquired by Bain & Company.

Umbrage creates custom software for companies by partnering with an internal technology team that makes the products. It’s a “teach a man to fish” method that has brought the company great success in creating software such as Shell’s TapUp app.

Bain & Company works with clients in 64 cities across 39 countries, meaning the global consultancy is positioned to bring Umbrage worldwide.

"Alongside Bain, we can deliver enhanced end-to-end solutions that will position our clients for success and to adapt during waves of disruptive emerging technologies," says CEO Womble in the release.

Bain’s Vector program has advised more than 6,700 digital projects around the world and across industries. It works by creating joint teams featuring Bain’s consulting staff, allowing companies to reach their digital goals themselves, but with a little help, not unlike Umbrage’s own methods. Acquiring Umbrage gives Bain a boost in its ability to help clients on a larger scale.

"Bain's commitment to delivering results with clients requires expanding and enhancing its ability to innovate and industrialize digital solutions," says Arpan Sheth, global leader of Vector, Bain's digital delivery platform. "Joining forces with Umbrage will allow us to develop a best-in-class, craft-centric digital product and venture building studio that will enable our clients to not only develop successful digital strategies, but to also execute on these strategies through world-class software capabilities. Umbrage further enhances Bain's Next solution to support our clients in their business building missions.”

Once the deal is completed, Umbrage will operate independently, but as a branded service line that’s part of Bain Innovation & Design. But existing clients needn’t worry. Umbrage will continue to assist them, including clients in financial services, energy, natural resources, and other industries.

In 2021, Umbrage raised a $2 million round led by Rice Investment Group. Womble previously joined the Houston Innovators Podcast to share how Houston has played a role in the company's growth.

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from energy to health care — recently making headlines in Houston innovation.

Will Womble, CEO of Umbrage

Startup founder on how Houston has evolved as a software hub — and why there's no better place to be

Will Womble describes his company, Umbrage, as fiercely loyal to Houston. The business, which publicly launched earlier this year, supports companies large and small with their software design, development, and more. Womble says he saw a void in Houston for this type of company, and he's attempting to fill it.

"What makes us different is speed to market — we're all onshore. We're all Houston-based, with the exception of five of our 40 employees," Womble says. "Houston was our focus and mission."

Womble has seen Houston evolve as an innovation ecosystem over the years, and now the game has changed. Click here to read more.

ALLY Energy announced it has acquired Clean Energy Social, a jobs and networking community for the clean energy industry. The deal expands ALLY's platform into the solar, wind, power, oil and gas, power and utilities, biofuels, hydrogen, geothermal, carbon capture, and other sectors that make up the energy transition.

"It's time to tackle the enormous challenge of the energy transition by connecting companies and candidates to resources so we can reduce the time and capital it takes to recruit and reskill," says Katie Mehnert, founder and CEO of ALLY Energy, in a news release. "We can speed up decarbonization by centralizing resources into one digital experience. This acquisition is a much-needed human capital investment to advance net-zero goals."

Saranas Inc. announced that it closed a $12.8 million series B investment led by Wisconsin-based Baird Capital, the venture capital and global private equity arm of Baird, a global company with a location in Houston. Austin-based S3 Ventures also supported the round. The company will use the funds to continue its clinical trials, per a news release.

"We are pleased to announce this round of funding led by Baird Capital," says Saranas President and CEO James Reinstein in the release. "It underscores the importance of real-time monitoring of bleeding complications and our opportunity to accelerate the commercialization of Early Bird. We look forward to expanding our clinical evidence through prospective clinical trials and launching next generation products, including Bird on a Wire, to address a much broader range of endovascular procedures."

HOUSTON INNOVATORS PODCAST EPISODE 94

It's no understatement to say that Will Womble is incredibly proud to be a Houstonian. The former actor and lawyer first got involved in the startup world by way of Austin — but he always advocated for his hometown.

"Houston is always third in line when it comes to the 'cool kid' in Texas," Womble says on this week's episode of the Houston Innovators Podcast. "But when you look at what's here, there's not a city outside of New York City with as many Fortune 500 companies. ... I just wanted to go prove that Houston has some really talented software developers just clamoring for the opportunity to show the talent."

An early hire at Chaotic Moon — later acquired by Accenture, Womble co-founded Austin-based Hypergiant before founding his latest venture, Umbrage. The company, which publicly launched earlier this year, supports companies large and small with their software design, development, and more.

The company, which Womble describes as a service-focused, crafts-based digital studio, works with its clients to design, develop, and deliver enterprise software that's cutting edge and scalable. The other thing? Umbrage is fiercely loyal to Houston. Womble says he saw a void in Houston for this type of company, and he's attempting to fill it.

"What makes us different is speed to market — we're all onshore. We're all Houston-based, with the exception of five of our 40 employees," Womble says. "Houston was our focus and mission."

Womble has seen Houston evolve as an innovation ecosystem over the years, and now the game has changed — especially when it comes to hiring, which has gotten very competitive.

"You see all of these great companies that aren't just bootstrapping but raising significant venture funding," Womble says. "It's awesome, but it's also making the landscape from the talent perspective very competitive. It was hard enough for a lot of industrial enterprise to attract talent before all of these startups were infused with capital to build their own teams."

These types of challenges aren't a deterrant for Womble — it's exciting for him.

"It's a really awesome time to be called a Houstonian," he says.

Womble shares more on his circuitous career and how he's seen the Houston innovation ecosystem evolve on the podcast. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

money moves

A software startup in Houston has leveled up thanks to new funding. Houston-based digital studio Umbrage has reportedly raised $2 million.

Founded in 2019 by Will Womble, Umbrage creates custom software solutions for companies within digitally transforming industries, such as oil and gas, healthcare, and supply chain.

"Umbrage is a new way that enterprises can overcome the inherent challenges of building and scaling digital solutions," Womble, who also serves as CEO, says in a news release. "Umbrage partners with internal technology teams to create scalable products that directly impact business' success. And by training our clients to effectively scale and improve these custom-built solutions, we're setting up our customers for long-term, sustainable success."

The round was led by Rice Investment Group — which, according to the release, has been a client of Umbrage as well as an investor.

"We've utilized Umbrage's custom solutions in our portfolio companies with great success and we can attest to the customer value proposition," says Danny Rice, a Partner of Rice Investment Group. "We're thrilled to support Umbrage's growth and enable forward-thinking businesses to unlock the business potential that digital solutions from Umbrage can deliver."

According to the release, Umbrage was able to be cash-flow-positive within weeks of starting and has already grown its team to nearly 40 employees. Clients include Cold Bore Technologies, Sumitomo Corp., and cpap.com.

"Umbrage brings a product-first mindset that continues to influence our organization far beyond what is expected from a software vendor," says Edwin Suarez, vice president and chief digital officer at SC Global Tubular Solutions. "Our team has been challenged with digital business models from ideation through product development and partnering with Umbrage helps us focus on long-term strategy while ensuring delivery on our immediate needs."

Venus Aerospace picks up investment from Lockheed Martin Ventures

space funding

Venus Aerospace, a Houston-based startup specializing in next-generation rocket engine propulsion, has received funding from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, for an undisclosed amount. The product lineup at Lockheed Martin includes rockets.

The investment follows Venus’ successful high-thrust test flight of its rotating detonation rocket engine (RDRE) in May. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

Venus says the Lockheed Martin Ventures investment reflects the potential of Venus’ dual-use technology for defense and commercial uses.

“Venus has proven in flight the most efficient rocket engine technology in history,” Venus co-founder and CEO Sassie Duggleby, a board member of the Texas Space Commission, said in a news release. “With support from Lockheed Martin Ventures, we will advance our capabilities to deliver at scale and deploy the engine that will power the next 50 years of defense, space, and commercial high-speed aviation.”

Chris Moran, executive director and general manager of Lockheed Martin Ventures, said Lockheed Martin has been a longtime supporter of early-stage “transformational” technologies.

“Our investment in Venus Aerospace reflects a conviction that next-generation propulsion will define which nations lead in space and defense for decades to come,” Moran added in the release. “We are committed to helping Venus scale this technology and integrate it into critical systems.”

Since its founding in 2020, Venus has secured more than $106 million in funding. In addition to Lockheed Martin Ventures, investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. Supporters of Venus include NASA, the Air Force Research Lab and the Defense Advanced Research Projects Agency (DARPA).
