A handful of Houstonians have been named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

Kip Daujotas is an investment associate at Aramco Ventures, a $7.5 billion venture capital arm of the world's largest energy company. Houston is the Americas headquarters for Saudi Aramco. Since its inception in 2012, Aramco Ventures has invested in more than 100 tech startups. Daujotas joined the team over two years ago after studying for an MBA at Yale University. He led Aramco’s first direct air capture (DAC) investment — in Los Alamos, New Mexico-based Spiritus.

Also representing the corporate side of the industry, Wenting Gao immigrated from Beijing to obtain an economics degree from Harvard University, then got a job at consulting giant McKinsey, where she recently became the firm’s youngest partner. Gao works on bringing sustainability strategies to energy and materials companies as well as investors. Her areas of expertise include battery materials, waste, biofuels, and low-carbon products.

Last but not least, Houston entrepreneur Rawand Rasheed is co-founder and CEO of Houston-based Helix Earth. He co-founded the startup after earning a doctoral degree from Rice University and co-inventing Helix’s core technology while at NASA, first as a graduate research fellow and then as an engineer. The core technology, a space capsule air filtration system, has been applied to retrofitting HVAC systems for commercial buildings.

Each year, Forbes 30 Under 30 recognizes 600 honorees in 20 categories. The 2025 honorees were selected from more than 10,000 nominees by Forbes staff and a panel of independent judges based on factors such as funding, revenue, social impact, scale, inventiveness, and potential.

Specifically, the Energy & Green Tech category recognizes young entrepreneurs driving innovation that’s aimed at creating a cleaner, greener future.

“Gen Z is one of the fastest-growing groups of entrepreneurs and creators, who are reshaping the way the world conducts business, and our Under 30 class of 2025 proves that you can never begin your career journey too early,” says Alexandra York, editor of Forbes Under 30. “With the expansion across AI, technology, social media, and other industries, the honorees on this year’s list are pushing the boundaries and building their brands beyond traditional scopes.”

Houston corporate venture leader calls for collaboration across sustainable fuel, innovation community

HOUSTON INNOVATORS PODCAST EPISODE 212

When it comes to the future of aviation — namely, making it more sustainable, a rising tide lifts all boats. Or, in this case, planes.

Andrew Chang, managing director of United Airlines Ventures, explains that working together is the key for advancing sustainable aviation fuel, or SAF. That's why United Airlines started the Sustainable Flight Fund, a $200 million initiative with support from industry leaders, including Air Canada, Boeing, GE Aerospace, JPMorgan Chase, Honeywell, Aramco Ventures, Bank of America, Hawaiian Airlines, JetBlue Ventures, and several others.

"We all recognize that we may compete in our core business, but with the importance of sustainable aviation fuel and given that it's an industry that doesn't exist — you can't compete for something that doesn't exist — let's collaborate and work together to explore technologies that can directly or indirectly support the commercialization and production of sustainable aviation fuel," he says on the Houston Innovators Podcast.

Within United Airline Ventures, Chang's job is to find technology to invest in across the aviation industry spectrum — from SAF to digital technologies that will improve the United customer experience. This means working with startups and other organizations to find the best fit — and, because he's based in Houston, one of United's seven key hubs, this means knowing and interacting with local innovators.

"The knowledge base and the capabilities are here — that's undebatable," Chang says of the Houston innovation ecosystem. "The next step is making sure we're accessing, promoting, collaborating, and learning from one another."

Again, as Chang recognizes, collaboration is key to further developing the ecosystem, "so that we're not trying to solve the same problem in a vacuum," he explains.

United Airlines recently signed an offtake agreement with Cemvita Factory, a Houston biotech startup that's working on SAF. Chang discusses this partnership on the show, as well as explaining how he works with other startups and what he's looking for.

Howard Berman, as co-founder and CEO, has been at the helm of Coya Therapeutics as its hit some major milestones — from raising over $20 million in venture investment to taking the company public. Coya's IPO occured in a tough market — only 12 biotech companies went public last year, Berman explains on the Houston Innovators Podcast. To Berman, that just proves how passionate the team was about getting this product to those who need it.

"It really says something for the fortitude and our team to come together to make it happen," he says on the show. "We're able to deliver and execute in a difficult market climate.

"Once you're a public company, you have different expectations," he continues. "But you also have the opportunity to go out and attract additional investors in ways you can't do as a private company." Read more.

Shipley Donuts launches AI-powered ordering assistant

fresh tech

Popular Houston-born doughnut chain Shipley Donuts has added a first-of-its-kind AI-powered assistant to its online ordering platform.

The new assistant can create personalized order recommendations based on individual or group preferences, according to a news release from the company. Unlike standard chatbox features, the new assistant makes custom recommendations based on multiple customer factors, including budgetary habits, individual flavor preferences and order size.

"We're not just adding AI for the sake of innovation — we're solving real customer pain points by making ordering more intuitive, personalized and efficient," Kerry Leo, Shipley Vice President of Technology, said in the release.

The system also works for larger events, as it can make individual orders and catering recommendations for corporate events and meetings by suggesting quantities and assortments based on group size, event type and budget.

According to Shipley, nearly 1 in 4 guests have completed orders with the new AI technology since it launched on its website.

“The integration of the AI ordering assistant into our refreshed website represents a significant leap forward in how restaurant brands can leverage technology to enhance the customer experience,” Leo added in the release.

Houston company wins AHA competition for pediatric heart valve design

winner, winner

Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

EO Houston is where ambitious founders go to scale smarter

Don't Go It Alone

Scaling a business from early traction into true growth is one of the most exciting — and punishing — chapters of entrepreneurship. Houston founders know this better than most. Our city is built on ambition: fast-moving industries, talent from around the world, and opportunities that expand as large as the Texas sky.

But as many entrepreneurs eventually learn, scaling isn’t simply “more of what worked.” It requires new systems, new thinking, and often, a new version of the founder. Even the most capable founders eventually face decisions, pressures, and turning points that only other entrepreneurs can truly understand.

Entrepreneurs’ Organization, a global peer-to-peer network of more than 18,000 business owners across 220 chapters in 75+ countries, exists for exactly this stage. One of the largest chapters in the organization, EO Houston brings that global community to life locally, offering founders the connection, learning, and accountability needed to grow sustainably and to grow up as leaders.

A community where founders learn at the highest level
The real value of EO emerges in the lived experiences of other entrepreneurs. When Houston-area founders talk about the moments growth nearly broke their companies, a universal theme appears: you can’t do it alone.

EO Houston member Robert De Los Santos of Sky High Party Rentals learned this the hard way when rapid post-COVID growth made expansion feel limitless — until it wasn’t.

“After COVID, we doubled every year and assumed inventory was the limit. In 2023 we overbought, only to realize demand had peaked. That taught us a hard truth: growth in one city has ceilings. Expanding into Austin and Dallas — the Texas Triangle — gave us new markets to put our inventory to work while we figured out how to penetrate Houston better. The challenge shifted from a strategy of ‘buy more units for demand’ to learning how to tackle the challenges of ‘leading across cities.’”

Founders often enter EO exhausted from trying to maintain control as things grow more complex. Many discover, like Jarred King of Summit Firms, that scaling requires the difficult shift from doing everything to building the team that can.

“We grew quickly because of my network, relationships, and hustle… but I was doing all the work,” King says. “I realized at that point you have to delegate — not just busy work, but important decisions to your key team, as well as set up really effective SOPs.”

“The uncomfortable truth is that you are no longer the best person for most jobs in your company," agrees Darren Randle of Houston Tents & Events. "Your inability to delegate or hire people smarter than you in key leadership and management level roles will become the single biggest drag on the entire business. You have to accept that your original 'hustle' is now a scalability risk."

Making hard decisions, such as walking away from customers or contracts, can feel like less of a sting when you know others have also been faced with tough choices. Aaron Gillaspie of West U's My Salon Suite recalls, “You can’t be everything to everyone, it’s ok to say no, and just understand some customers aren’t the right fit. It’s a two way street and both must win.”

Perspective is perhaps the most important reality check that members find at EO.

“Bigger volume will not make problems go away — you just got to get used to walking the tightrope," says Roger Pombrol of Emerald Standard. "Develop a system for good balance and do not freak out. Scared is no way to live your life. It’s ok if you fall. Your family will still love you. Money is just money. Love is love. The world tries to make you conflate them, but don’t."

Actionable insights from entrepreneurs who’ve already scaled
Conversations like these are happening every month inside EO Forum Meeting. Each EO chapter is divided into several small Forums. These confidential, committed group of 7–10 entrepreneurs who meet to share the real five percent of what they’re experiencing. It’s not advice, but experience — shared candidly, respectfully, and with the kind of vulnerability that leads to breakthroughs.

What makes Forum so impactful is the honesty it draws out. Entrepreneurs are often surrounded by employees, partners, and even family members who rely on them for answers, but seldom do they have a group where vulnerability is not only welcomed, but expected.

Learning experiences that match your ambition
EO supports that growth far beyond peer groups. Through the organization’s global partnerships with institutions like Harvard, Oxford, and INSEAD, Houston members gain access to executive-level learning experiences designed specifically for entrepreneurs.

These programs help founders step out of the day-to-day and think strategically about competitive advantage, innovation, and organizational leadership. Paired with ongoing learning through EO Jumpstart, Nano Learning, and its global library of member-created content, founders stay informed, challenged, and ahead of emerging trends.

And through global communities — ranging from EO Women and EO Under 35 to industry-specific groups — Houston members tap into expertise that spans continents and sectors. Whether someone is navigating M&A, exploring international expansion, or integrating new technologies, the right perspectives are always within reach.

What truly distinguishes EO Houston, however, is its culture. Houston’s entrepreneurial landscape is uniquely diverse and resilient, filled with founders who are hungry to build, innovate, and elevate the city’s business community. EO Houston amplifies that spirit, creating relationships that are as supportive as they are strategic. Many members describe the chapter not simply as a network, but as a catalyst for becoming better leaders, better thinkers, and — just as importantly — better human beings.

Your next level starts here
For entrepreneurs who are ready to scale—beyond their first million, beyond their current comfort zone, and toward a future that requires sharper leadership and stronger community—EO Houston offers an unmatched platform. It is a place where ambitious founders grow faster, think bigger, and gain the confidence to take bold next steps.

If you’re ready to elevate your business and your leadership alongside people who understand the journey, EO Houston is ready to welcome you. Your next level starts with the peers who can help you reach it. Learn more and become a member here.
