Raising funds anytime soon? Take these tips from a venture capital insider into consideration. Photo via Getty Images

I have had the incredible opportunity to work with New Stack Ventures as a venture fellow, and after sourcing investment opportunities, shadowing calls with founders, and even leading a couple calls of my own, I have learned a few lessons that might resonate with startup founders who are raising capital.

Responsive founders make a difference

The first and likely most important lesson I have learned during my tenure as a fellow is this: responsive founders truly make a difference in whether or not they raise capital.

I have sent several emails and LinkedIn messages to really intriguing companies, in hopes of connecting for a call and inquiring about their raise. And, I look back and see that many of those outreach messages were left unread. I have also engaged in calls with really intriguing companies where the founder never follows up, and the idea of moving forward with next steps dissipates.

On the flipside of the forgetful founder, I have also witnessed extremely attentive founders: founders who send follow-up messages when they don't receive an immediate response, respond to their emails within the hour, and go above and beyond by sending pitch decks and executive summaries (even when unasked). This type of founder persona excites me with their enthusiasm and eagerness to make a deal. Their responsiveness with the investment process sheds light to how they likely run their businesses.

At the end of the day, many founders can say that they are hustlers and go-getters, but I believe the founders that show me through their actions in the investment process.

Great founders are great storytellers

When I do connect with founders in introductory calls (after the back-and-forth, hopefully responsive email exchange), the thing I look forward to most is hearing their stories. I want to know your story. I want to know what you were doing before your startup (and how that helped prepare you), how you thought of your idea, how you validated your assumptions, how you grew your business, and… everything in between (but all in less than five minutes of time).

Great founders are great storytellers. The great storytellers I have come across invite me into their companies' journeys, and leave me actually caring about their success.

On the opposite side of the spectrum, the founder who gives short responses and shows no real connection to their work (giving off the vibe that this is just another startup for them) leaves me unattached to them and their business.

Venture capitalists are more accessible than you might think

Perhaps, I gave this point away when I said that I was sending several emails and LinkedIn messages to founders (which sounds a little desperate), but VCs are way more accessible than you may think. Before working with New Stack Ventures, I had this perception that VCs were extremely hard to reach, exceptionally busy, and a little bit scary. And while one of the two latter characteristics still remains true, I can say with certainty that VCs are not hard to reach.

I can't speak for everyone in venture capital, but I do know that the VCs I work with will respond to founders who message them. Putting yourself out there, as a founder, can lead to advice (which bodes well for your business), a new connection in the industry (which bodes well for your network), and even an investment (which bodes well for the future of your startup). In the end, VCs are spending hundreds of hours, searching for a tractable startup that will change the game, and your startup could be the very gem they are looking for.

So, be bold, be responsive, and tell your story to any and every VC who will listen. I'm all ears.

InformAI is providing solutions for data optimizations in health care — something that'll allow for better diagnoses and treatment. Jim Havelka shares on the Houston Innovators Podcast last week that his company's success is due to being headquartered in Houston and tied to the Texas Medical Center. The company's team works out of JLABS @ TMC as well as TMC Innovation Institute.

"Those relationships have been very helpful in getting data to build these particular products," Havelka says. "Just the Texas Medical Center alone has roughly 10 million patient encounters every year. The ability to get access to data and, equally important, the medical experts has been a tremendous benefit to InformAI." Click here to read more and stream the podcast.

Charles Turner saw an inefficiency in senior health care staffing — even before the industry was rocked by a pandemic. He founded Kare Technologies to use software to address this problem. In light of COVID-19, the need for better staffing solutions grew across industries and Kare expanded its features to reach hotel and restaurant workers.

"We'd always plan on doing this, and with the advent of COVID we accelerate our development on the hospitality side," Turner says. Click here to read more.

Houston startup debuts bio-based 'leather' fashion collection in Milan

sustainable fashion

Earlier this month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.

Houston clean energy co. secures $100M to deploy tech on global scale

Going Global

Houston-based Utility Global has raised $100 million in an ongoing Series D round to globally deploy its decarbonization technology at an industrial scale.

The round was led by Ara Partners and APG Asset, according to a news release. Utility plans to use the funding to expand manufacturing, grow its teams and support its commercial developments and partnerships.

“This financing marks a critical step in Utility’s transition from a proven technology to full-scale global commercial execution,” Parker Meeks, CEO and president of Utility Global, said in the release. “Industrial customers are no longer looking for pilots or promises; they need deployable solutions that work within existing assets and deliver true economic industrial decarbonization today that is operationally reliable and highly scalable. Utility’s technology produces both economic clean hydrogen and capture-ready CO2 streams, and this capital enables us to scale and deploy that impact globally with speed, discipline, and rigor.”

Utility Global's H2Gen technology produces low-cost, clean hydrogen from water and industrial off-gases without requiring electricity. It's designed to integrate into existing industrial infrastructure in hard-to-abate assets in the steel, refining, petrochemical, chemical, low-carbon fuels, and upstream oil and gas sectors.

“Utility is tackling one of the most difficult challenges in the energy transition: decarbonizing hard‑to‑abate industrial sectors,” Cory Steffek, partner at Ara Partners and Utility Global board chair, said in the release. “What sets Utility apart is its ability to compete head‑to‑head with conventional fossil‑based solutions on cost and reliability, even as it materially reduces emissions. With this new funding, Utility is well-positioned for its next chapter of commercial growth while maintaining the technical excellence and capital discipline that have defined its development to date.”

Utility Global reached several major milestones in 2025. After closing a $53 million Series C, the company agreed to develop at least one decarbonization facility at an ArcelorMittal steel plant in Brazil. It also signed a strategic partnership with California-based Kyocera International Inc. to scale global manufacturing of its H2Gen electrochemical cells.

The company also partnered with Maas Energy Works, another California company, to develop a commercial project integrating Maas’ dairy biogas systems with H2Gen to produce economical, clean hydrogen.

"These projects were never intended to stand alone. They anchor a deep and growing pipeline of commercial projects now in development globally across steel, refining, chemicals, biogas and other hard-to-abate sectors worldwide, Meeks shared in a 2025 year-in-review note. He added that 2026 would be a year of "focused acceleration to scale."

Houston Methodist awarded $4M grant to recruit head of Neal Cancer Center

new hire

Armed with a $4 million state grant, the Houston Methodist Academic Institute has recruited a renowned expert in ovarian and endometrial cancer research to lead the Dr. Mary and Ron Neal Cancer Center.

The grant, provided by the Cancer Prevention and Research Institute of Texas, enabled the institute to lure Dr. Daniela Matei away from Northwestern University’s Feinberg School of Medicine in Chicago. There, she is the Diana Princess of Wales Professor in Cancer Research and chief of the Division of Reproductive Science in Medicine.

Matei will succeed Dr. Jenny Chang, who was hired last year to run the Houston Methodist Academic Institute.

At the Neal Cancer Center, located in the Texas Medical Center complex, oncologists work on innovations in cancer research, treatment, and technology. The center opened in 2021 after the Neals donated $25 million to expand Houston Methodist’s cancer research capabilities. It handles about 7,000 new cases each year involving more than two dozen types of cancer.

U.S. News & World Report puts Houston Methodist Hospital at No. 19 among the country’s best hospitals for cancer care, two spots below Chicago’s Northwestern Memorial Hospital. The University of Texas MD Anderson Cancer Center in Houston sits at No. 1 on the list.

Matei’s research related to ovarian and endometrial cancer holds the potential to benefit tens of thousands of American women. The American Cancer Society estimates:

  • 21,010 women in the U.S. will be diagnosed with ovarian cancer, and 12,450 women will die from it.
  • 68,270 women in the U.S. will be diagnosed with endometrial cancer, and 14,450 women will die from it.

Matei is leaving Northwestern in the wake of widespread cuts in federal funding for medical research. The National Institutes of Health (NIH) has canceled or frozen tens of millions of dollars in grants for Northwestern, the Wall Street Journal reports, and the university has been plugging the gaps with its own money.

“The university is totally keeping us on life support,” Matei told the newspaper last year. “The big question is for how long they can do this.”

According to the Wall Street Journal, Matei’s $5 million NIH grant supporting 69 cancer trials has been caught up in the federal funding chaos, so Northwestern stepped in to cover trial expenses such as nurses’ salaries and diagnostic procedures.

Trial participants include some patients with rare, incurable tumors who are undergoing experimental treatments aligned with the genetics of their condition, the newspaper says.

“It’s certainly a life-and-death situation for cancer patients on these trials,” Matei said in 2025.

Matei is among the beneficiaries of more than $15 million in grants approved February 18 by CPRIT’s board. The grants went toward recruiting five cancer researchers to institutions in Texas.

One of those grants, totaling $1.5 million, went to the University of Houston to recruit Akash Gupta, a research scientist at MIT’s Koch Institute for Integrative Cancer Research. The remaining grants went to recruit scientists to The University of Texas at Dallas and The University of Texas Southwestern Medical Center.
