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.

Italian aerospace company sets up first U.S. office at Houston Spaceport

welcome to houston

Como, Italy-based aerospace company Involve Space recently made the Houston Spaceport the site of its first U.S. office.

Involve Space develops high-altitude balloon platforms for Earth observation, scientific research and hardware testing. The balloons carry instruments into the stratosphere (a layer of the upper atmosphere) to collect images and data, conduct experiments and test technology.

The company plans to launch its first commercial missions from Houston by the end of this year, according to a news release.

“Houston is the global center of aerospace, and our presence at Houston Spaceport strengthens our international growth trajectory,” Jonathan Polotto, founder and CEO of Involve Space, said in the release.

Founded in 2021, Involve Space incorporates aerospace hardware, AI and geospatial tools into its offerings. Its proprietary CLEAR platform uses conversational AI to help customers interpret data and support decision-making.

Located at Ellington Airport, the Houston Spaceport provides a base for Involve Space’s North American operations, including business development and partnerships with aerospace companies and researchers.

Other tenants at the Houston Spaceport include NASA, Axiom Space, Venus Aerospace and Intuitive Machines.

Involve Space’s relationship with the Houston Spaceport began in January 2025, when it conducted its first U.S. pilot launch. During the five-hour mission, the balloon reached an altitude of about 85,000 feet and traveled about 250 miles across Texas.

One of Involve Space’s first U.S. customers is Houston-based Rhodium Scientific, a space biotech company. Polotto and Rhodium Scientific founder and CEO Olivia Gamez Holzhaus signed a deal to conduct biotech experiments aboard Involve Space’s stratospheric balloon platforms before planned missions to orbit.

“The presence of innovative platforms like those developed by Involve strengthens the Spaceport’s role as a site for testing, validating, and deploying advanced technologies between aeronautics and space,” Jim Szczesniak, director of aviation for Houston Airports, added in the release.

UH lands $3M grant to expand opioid overdose training

Overdose Response

The University of Houston has received a $3 million federal grant to expand its potentially life-saving overdose response training program.

The grant will support the Houston Health Department’s FRONTLINES program that trains first responders in Harris and Fort Bend counties to recognize opioid overdoses and administer the drug naloxone, which can counter the effects of an opioid overdose. The four-year grant comes from the Substance Abuse and Mental Health Services Administration within the Department of Health and Human Services, and it builds on eight years of work at UH, according to a release from the university.

As part of the expansion, UH medical, social work and psychology students will now also be able to take part in FRONTLINES’ overdose-response training. Some of the students will also be selected to help train community members, ultimately passing along the life-saving skills throughout Houston.

FRONTLINES is a collaboration with the City of Houston, the Fertitta College of Medicine, Baylor College of Medicine and the Houston Recovery Center. It was co-founded by Dr. James Bray, chair of the Department of Behavioral and Social Sciences at the University of Houston’s Tilman J. Fertitta Family College of Medicine, in 2018.

“When someone experiencing an opioid overdose is reached in time, naloxone can save their life,” Bray said in a news release. “We’ve seen the impact this training can have in Houston, and now we have an opportunity to extend that reach across Harris and Fort Bend counties, putting lifesaving knowledge and tools into the hands of more first responders.”

In 2024, around 450 residents of Harris County died from opioid overdoses, according to a Texas Department of State Health Services report. The report found that fentanyl was involved in about three-quarters of the deaths.

In 2025, UH also received a $2.6 million gift from the estate of Dr. William A. Gibson to expand its opioid research and develop a vaccine to help block fentanyl's effectiveness in entering the brain. The vaccine research is part of the Michael C. Gibson Addiction Research Program led by UH professor of psychology Therese Kosten and founding member of the UH Drug Discovery Institute Colin Haile.

Texas public libraries drive billions in economic impact, report finds

Beyond the Stacks

A new statewide study examining the economic impacts of public libraries has revealed they have generated over $3.8 billion in value to local communities — a return of $4.74 for every $1 invested.

The report, "Beyond the Stacks: Measuring the Economic and Community Value of Texas Public Libraries" was conducted by third-party consultancy JBK Economics Group in partnership with the Texas Library Association. About 300 of the total 513 public libraries in Texas participated in a survey for the report.

A major finding from the survey revealed that public libraries create billions in economic value for the communities they serve at a fraction of what it costs to pay employee wages and benefits, operating expenditures, and capital expenditures. About 11,200 jobs were directly and indirectly supported by public libraries, the report found.

The report found its $4.74 to $1 ratio by adding up the total value of the services provided by these institutions (an estimated $2.48 billion), and comparing it to total expenditures ($808.6 million).

"Public libraries had about the same economic footprint as the Texas motion picture and sound recording industry ($2.9 billion in Gross Domestic Product in 2024) or the Texas paper manufacturing industry ($4.0 billion in Gross Domestic Product in 2024)," the report said.

Many Houstonians are already familiar with Houston Public Library's expansive catalog and programming, but there are many more services the library provides that might fly under the radar. A few examples include access to subscription-based research databases and news outlets, and the Library of Things, a collection of cookware and bake ware, musical instruments, craft kits, and other tools or activity materials that are available for cardholders to borrow. Individual branches also provide free Wi-Fi, computer access, and meeting spaces.

Houston-area residents also have access to services at several other local libraries depending on their address, such as the Harris County Public Library, Montgomery County Memorial Library System, or Fort Bend County Libraries, just to name a few.

These are additional services and partnerships that Texas public libraries commonly provide, per the survey results:

93 percent provide voter registration and/or serve as voting locations
84 percent provide partnerships with local social services agencies
82 percent provide job application assistance
68 percent facilitate applications for government benefits
38 percent provide on-site social services
30 percent provide telehealth rooms and/or resources

"Public libraries are practical, welcoming and rooted in the communities they serve — they are unmistakably Texan," said Texas Library Association executive director Shirley Robinson in a press release. "This study puts a dollar value on the opportunities libraries create every day. Whether someone visits a library to apply for a job, access the internet, learn a new skill or simply find a new favorite book, those services create real value for Texans and their communities."
