What Houston startup founders looking for funding need to know about working with VCs

guest column

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, founder of Kare Technologies

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.

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

Conroe-based Hertha Metals, a producer of substantial steel, hauled in more than $17 million in venture capital from Khosla Ventures, Breakthrough Energy Fellows, Pear VC, Clean Energy Ventures and other investors.

The money was put toward the construction and the launch of its 1-metric-ton-per-day pilot plant in Conroe, where its breakthrough in steelmaking has been undergoing tests. The company uses a single-step process that it claims is cheaper, more energy-efficient and equally as scalable as conventional steelmaking methods. The plant is fueled by natural gas or hydrogen.

The company, founded in 2022, plans to break ground early this year on a new plant. The facility will be able to produce more than 9,000 metric tons of steel per year. Continue reading.

The non-NASA contract is for an undisclosed government customer, which Intuitive Machines says reinforces its "strategic move to diversify its customer base and deliver orbital capabilities that span commercial, civil, and national security space operations." Continue reading.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
