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.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”

Other startups from around the world joined the Houston incubator in the same time period, including:

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

Intuitive Machines forms partnership with Italian companies for lunar exploration services

to the moon

Houston-based space technology, infrastructure and services company Intuitive Machines has forged a partnership with two Italian companies to offer infrastructure, communication and navigation services for exploration of the moon.

Intuitive Machines’ agreement with the two companies, Leonardo and Telespazio, paves the way for collaboration on satellite services for NASA, a customer of Intuitive Machines, and the European Space Agency, a customer of Leonardo and Telespazio. Leonardo, an aerospace, defense and security company, is the majority owner of Telespazio, a provider of satellite technology and services.

“Resilient, secure, and scalable space infrastructure and space data networks are vital to customers who want to push farther on the lunar surface and beyond to Mars,” Steve Altemus, co-founder and CEO of Intuitive Machine, said in a news release.

Massimo Claudio Comparini, managing director of Leonardo’s space division, added that the partnership with Intuitive Machines is a big step toward enabling human and robotic missions from the U.S., Europe and other places “to access a robust communications network and high-precision navigation services while operating in the lunar environment.”

Intuitive Machines recently expanded its Houston Spaceport facilities to ramp up in-house production of satellites. The company’s first satellite will launch with its upcoming IM‑3 lunar mission.

Intuitive Machines says it ultimately wants to establish a “center of space excellence” at Houston Spaceport to support missions to the moon, Mars and the region between Earth and the moon.
