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.

Note: I was inspired to write this piece by by The Full Ratchet's tips for fundraising entrepreneurs, I thought I would share.

3 Houston innovators to know this week

who's who

Editor's note: In the week's roundup of Houston innovators to know, I'm introducing you to three innovators recently making headlines — from health tech founders to a venture capital rising star.

Jim Havelka, founder and CEO of InformAI

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.

As a venture fellow, Christa Westheimer — who's a student at Rice University — works hard to find startups working on the next great thing. And she realizes there are so many Houston startups seeking funding, so she has some advice: get in touch.

"During my tenure as a venture fellow, I have been sifting through online resources — from Crunchbase and AngelList to LinkedIn — with the hopes of finding a really neat startup that would earn an investment from New Stack Ventures," she writes in a guest column for InnovationMap.

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.

Looking for VC funding? This Houstonian says to connect with venture fellows

guest column

Every venture capitalist is searching for the next greatest startup that can change the world — as well as provide a sizable return on their investment. Everyone knows this. And because everyone knows this, most entrepreneurs are sending their pitch decks and executive summaries to venture associates and deal leads. But, I'd like to propose that every entrepreneur who's interested in raising capital begin to pitch their startups to venture fellows, college-aged students who work with investment firms.

I am a venture fellow at New Stack Ventures where my main objective is to source investment opportunities. During my tenure as a venture fellow, I have been sifting through online resources — from Crunchbase and AngelList to LinkedIn — with the hopes of finding a really neat startup that would earn an investment from New Stack Ventures.

A few weeks ago, Crunchbase had run dry of Houston startups that I hadn't reviewed. Because of this deal drought, I posted in the Houston Startups Facebook Group, asking if anyone had any startups that might fit our pre-filter criteria, and I was introduced to 15 startup founders in a matter of minutes. I posted again in the Austin and Dallas/Fort Worth Startups Facebook Groups with similar results.

These experiences showed me that there are several hidden startups that need funding. And there are several venture fellows that need to meet deal quotas and strongly desire to source a startup that earns an investment from their firm. So, perhaps, we could marry these two groups and help them both succeed.

Here are three tips for connecting with venture fellows.

1. Find your firm fit.

VC-RANK.com allows you to compile a list of best-fit venture capital firms for your startup. You can begin with your curated list. You likely won't find venture fellows on the firm's "Team" or "About Us" pages, so you might have to do some digging by looking at the firm's LinkedIn page and their employees.

If your curated list of VC firms doesn't happen to have venture fellows, you can always try reaching out to venture fellows from these firms: Open Scout, Ripple Ventures, .406 Ventures, Crescent Ventures, Alley Corp, and Fin Venture Capital.

2. Share your startup with several venture fellows.

Through a quick LinkedIn message, you can share your startup by including your company website, your contact email address, and your basic raise information (i.e. How much have you previously raised? How much are you raising right now?).

3. Await further communication.

I can't speak for all venture fellows, but most of us are just college kids who have been given the opportunity to learn a whole lot at VC firms. Contacting venture fellows can be a great (and low-risk) way to get your company's name immediately on the list of potential investment opportunities for your ideal firm. And, you would be helping any venture fellow out by making the effort.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

Houston businessman and philanthropist to receive legendary Texas award

Making History

The Texas State History Museum Foundation (TSHMF) has set the date for its 23rd annual Texas Independence Day Dinner and unveiled the 2027 recipients of its prestigious History-Making Texan Award, which includes a prominent Houston businessman.

Since 2005, the organization has honored "living Texas legends whose contributions to the state and the nation have been truly historic and exceptional in scope and nature." Past galas have recognized prominent Texas figures such as former presidents George H.W. and George W. Bush and former first ladies Barbara and Laura Bush, as well as H-E-B chairman Charles Butt, among others.

The two 2027 History-Making Texan Award recipients are Texas Historical Commission chairman, businessman, and philanthropist John L. Nau, III, and trailblazing Texas actor, director, producer, and writer Taylor Sheridan. The 2027 gala will be held at the Bullock Texas State History Museum in Austin on March 2, Texas Independence Day.

"Our honorees are national leaders whose accomplishments have elevated Texas’ distinctive place on the national and international stage," Debbie Raynor, dinner chair and TSHMF Trustee, said in a statement. "John L. Nau, III and Taylor Sheridan have each, in very different ways, helped tell the Texas story — one through the preservation of our history and treasured places, the other through the power of storytelling that has brought Texas and the American West to audiences around the world.

"Nau is the former chairman and CEO of Silver Eagle Beverages, one of the largest Anheuser-Busch distributors in the U.S. He has served as chairman of the Texas Historical Commission since 2015. Raynor said Nau's "commitment to preservation" extends further than his protection of Texas historic sites "to the stewardship and conservation of the land itself, including his bay area lodge in South Texas and his ranch in West Texas.

"[Nau's] leadership and lifelong dedication to history have earned him national recognition, but perhaps his greatest legacy is his determination to ensure that the stories and places that shaped Texas endure for generations to come," Raynor said.Quadruple-threat filmmaker Sheridan is most widely recognized for his award-winning neo-Western TV series Yellowstone and its associated spin-offs 1883, 1923, Marshals, and Dutton Ranch. Raynor hailed Sheridan for his success in bringing a "remarkable new dimension to the way the world sees Texas and the American West."

"As a creator, writer, director, and executive producer of some of television’s most successful series, he has captured the imagination of audiences across the globe while bringing the people, landscapes, traditions and enduring spirit of the West into millions of homes," she said. "And he does more than tell the Texas story — he lives it, as a native Texan, accomplished horseman and steward of two legendary Texas ranches."

A release estimates about 450 "business, political, and community leaders" attend the Texas Independence Day Dinner each year, and proceeds will benefit the Bullock Museum's educational programs and special projects.

The 2027 Texas Independence Day Dinner will take place March 2, 2027, at the Bullock Museum in Austin. A VIP reception will start at 6:30 pm, followed by a 7 pm reception, and 7:30 dinner and program.

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.
