Houston-based Paladin, whose remotely controlled drones help first responders react quickly to emergencies, has collected $5.2 million in seed funding.

Gradient, a seed fund that backs AI-oriented startups, led the round. Also participating were Toyota Ventures, the early-stage VC arm of Japanese automaker Toyota; venture capital firm Khosla Ventures; and VC fund 1517.

“We believe Paladin will drive meaningful change in public safety and redefine how communities are served,” Gradient said in an announcement about the seed round.

In 2019, Paladin received $1.3 million in seed funding from Khosla Ventures and Gmail creator Paul Buchheit, a group partner at Y Combinator. In 2018, the year it was co-founded by Divyaditya Shrivastava and Trevor Pennypacker, Paladin graduated from Y Combinator’s three-month boot camp.

Paladin’s AI-enhanced autonomous drones help public safety agencies, such as police and fire departments, respond to 911 calls. These drones provide aerial views of emergency scenes in an effort to decrease response times, improve “situational awareness,” and save lives, according to a Gradient blog post.

Among the agencies that have tried out Paladin’s technology is the Houston area’s Memorial Villages Police Department. The department participated in a three-month Paladin pilot project in 2019.

"(This is) one of the first departments in the country to be testing this technology," Shrivastava told InnovationMap in 2019. "We're very limited in the area that we cover, and that's just because we're taking baby steps and going as carefully and deliberately as possible."

Gradient says more than 12,000 drone missions have been performed using Paladin’s hardware and software platform. Agencies that have adopted the platform report average response times under 90 seconds. Furthermore, the technology has allowed them to resolve nearly one-third of 911 calls without dispatching first responders.

“Paladin keeps innovating, recently launching Payload Drop, a groundbreaking feature that enables drones to deliver lifesaving equipment — such as Narcan, life vests, and AEDs — directly to emergency scenes,” says Gradient.

On its website, Paladin says it envisions autonomous drones responding to every 911 call in the U.S. by 2027.

“The information is paramount, the technology exists and is rapidly improving, and the need is there. We want to help,” Paladin proclaims.

Houston expert: Can Houston replicate and surpass the success of Silicon Valley?

guest column

Anyone who knows me knows, as a Houston Startup Founder, I often muse about the still developing potential for startups in Houston, especially considering the amount of industry here, subject matter expertise, capital, and size.

For example, Houston is No. 2 in the country for Fortune 500 Companies — with 26 Bayou City companies on the list — behind only NYC, which has 47 ranked corporations, according to Fortune.

Considering layoffs, fund closings, and down rounds, things aren’t all that peachy in San Francisco for the first time in a long time, and despite being a Berkeley native, I’m rooting for Houston now that I’m a transplant.

Let’s start by looking at some stats.

While we’re not No. 1 in all areas, I believe we have the building blocks to be a major player in startups, and in tech (and not just energy and space tech). How? If the best predictor of future success is history, why not use the template of the GOAT of all startup cities: San Francisco and YCombinator. Sorry fellow founders – you’ve heard me talk about this repeatedly.

YCombinator is considered the GOAT of Startup Accelerators/Incubators based on:

  1. The Startup success rate: I’ve heard it’s as high as 75 percent (vs. the national average of 5 to 10 percent) Arc Search says 50 percent of YC Co’s fail within 12 years – not shabby.
  2. Their startup-to-unicorn ratio: 5 to 7 percent of YC startups become unicorns depending on the source — according to an Arc Search search (if you haven’t tried Arc Search do – super cool).
  3. Their network.

YC also parlayed that success into a "YC Startup School" offering:

  1. Free weekly lessons by YC partners — sometimes featuring unicorn alumni
  2. A document and video Library (YC SAFE, etc)
  3. Startup perks for students (AWS cloud credits, etc.)
  4. YC co-founder matching to help founders meet co-founders

Finally, there’s the over $80 billion in returns, according to Arc search, they’ve generated since their 2005 inception with a total of 4,000 companies in their portfolio at over $600 billion in value. So GOAT? Well just for perspective there were a jaw-dropping 18,000 startups in startup school the year I participated – so GOAT indeed.

So how do they do it? Based on anecdotal evidence, their winning formula is said to be the following well-oiled process:

  1. Bring over 282 startups (the number in last cohort) to San Francisco for 90 days to prototype, refine the product, and land on the go-to-market strategy. This includes a pre-seed YC SAFE investment of a phased $500,000 commitment for a fixed min 7 percent of equity, plus more equity at the next round’s valuation, according to YC.
  2. Over 50 percent of the latest cohort were idea stage and heavily AI focused.
  3. Traction day: inter-portfolio traction the company. YC has over 4,000 portfolio companies who can and do sign up for each other’s companies products because “they’re told to."
  4. Get beta testers and test from YC portfolio companies and YC network.
  5. If they see the traction scales to a massively scalable business, they lead the seed round and get this: schedule and attend the VC meetings with the founders.
  6. They create a "fear of missing out" mentality on Sand Hill Road as they casually mention who they’re meeting with next.
  7. They block competitors in the sector by getting the top VC’s to co-invest with then in the seed so competitors are locked out of the A list VC funding market, who then are up against the most well-funded and buzzed about players in the space.

If what I've seen is true, within a six-month period a startup idea is prototyped, tested, pivoted, launched, tractioned, seeded, and juiced for scale with people who can ‘make’ the company all in their corner, if not already on their board.

So how on earth can Houston best this?

  1. We have a massive amount of businesses — around 200,000 — and people — an estimated 7.3 million and growing.
  2. We have capital in search of an identity beyond oil.
  3. Our Fortune 500 companies that are hiring consultants for things that startups here that can do for free, quicker, and for a fraction of the extended cost.
  4. We have a growing base of tech talent for potential machine learning and artificial intelligence talent
  5. A sudden shot at the increasingly laid off big tech engineers.
  6. We have more accelerators and incubators.

What do we need to pull it off?

  1. An organized well-oiled YC-like process
  2. An inter-Houston traction process
  3. An "Adopt a Startup" program where local companies are willing to beta test and iterate with emerging startup products
  4. We have more accelerators but the cohorts are small — average five to 10 per cohort.
  5. Strategic pre-seed funding, possibly with corporate partners (who can make the company by being a client) and who de-risk the investment.
  6. Companies here to use Houston startup’s products first when they’re launched.
  7. A forum to match companies’ projects or labs groups etc., to startups who can solve them.
  8. A process in place to pull all these pieces together in an organized, structured sequence.

There is one thing missing in the list: there has to be an entity or a person who wants to make this happen. Someone who sees all the pieces, and has the desire, energy and clout to make it happen; and we all know this is the hardest part. And so for now, our hopes of besting YC may be up in the air as well.

Houston health tech startup secures $16M series A, prepares for first U.S. clinical trials

money moves

Fueled by fresh funding in the bank, a medical device startup has announced upcoming trials.

VenoStent, Inc., a company developing an innovative tool to improve outcomes for hemodialysis patients, has closed $16 million in a series A round of financing. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round.

The company also announced it received Investigational Device Exemption from the FDA for its United States clinical trial, SAVE-FistulaS.

“Our mission at VenoStent is to improve the quality and length of life of dialysis patients. On the heels of our very promising results in several preclinical studies and a 20-patient feasibility study that led to our Breakthrough Designation last year, this recent IDE approval is perhaps our biggest milestone to date," Tim Boire, CEO of VenoStent, says in a news release. "We now enter an exciting new epoch in our company’s development that we believe will ultimately result in FDA Approval and vastly improve the quality and length of life for patients."

VenoStent's series A will fund the trial, expand manufacturing capabilities, and more. The company is targeting the more than 800,000 people in the U.S. with end-stage renal disease. Currently, more than half of the surgeries performed to initiate hemodialysis fail within a year. VenoStent's novel therapeutic medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

“This trial is designed to provide the highest level of clinical evidence. We’re excited to be in this position to treat the first patients in the United States with this technology, and demonstrate the safety and efficacy of our device,” continues Boire in the release.

Per the release, the company is aiming for FDA Approval and be the first-to-market device to improve hemodialysis access surgery.

“We’re extremely pleased to be partnering with VenoStent on this critical mission. This company and technology are poised for commercial success to address a critical, unmet need,” says Bob Crutchfield, operating partner at Good Growth Capital, in the release.

The TMC Venture Fund also contributed to the series A investment round, along with SNR, Baylor Angel Network / Affinity Fund, Creative Ventures, Cowtown Angels, Alumni Ventures, and other notable angel investors. Past investors in VenoStent include KidneyX, National Science Foundation, National Institute of Health, Y Combinator, Health Wildcatters, and the Texas Halo Fund.

“VenoStent’s data and traction to date is impressive and gives us a lot of confidence in their continued success. We look forward to helping them get this Breakthrough product to market and help patients that are in dire need of this innovative technology,” says Joel Whitley, partner at IAG Capital Partners, in the release.

Houston drone company creating the next generation of first responders

To the rescue

When 911 is called, first responders usually arrive at the scene around three or four minutes after the call's placed. But Houston-based Paladin Drones wants to have eyes on the ground ­— or eyes in the sky — within the first 30 seconds.

The company's mission is simple: to outfit public agencies and first-responders with drones that can be autonomously deployed to the site of an emergency. Equipped with thermal sensors and flying around 200 feet high, the drones can give police and firefighters near-instantaneous information on a situation underway.

At the beginning of April, Paladin Drones began working with the Memorial Villages Police Department to respond to incidents in Memorial Villages, Hunter's Creek, Piney Point Village, and Bunker Hill.

"(This is) one of the first departments in the country to be testing this technology," says Paladin Drones co-founder Divyaditya Shrivastava. "We're very limited in the area that we cover, and that's just because we're taking baby steps and going as carefully and deliberately as possible."

Paladin Drones was co-founded by Shrivastava and Trevor Pennypacker. In 2018, the company went through a three-month boot camp at Y Combinator, a California-based incubator that's churned out Dropbox, AirBNB, Instacart and more. Through Y Combinator, Paladin Drones was connected with venture capital investors in Houston.

The company's drones capture critical information, such as a vehicle's color and body type, a suspect's clothing, or the direction a suspect fled the scene. And since roughly 70 percent of 911 calls involve witnesses or passerby giving inaccurate information about the emergency's location, these drones will be able to pinpoint the exact location of an emergency, further aiding the arrival of first responders.

"We're working on tracking technology to give the drones the capability to auto-follow (suspects)," Shrivastava says.

Paladin Drones is looking to hire a handful of employees in the coming months, Shrivastava says. He declined to disclose any information on the company's funding plans, but said it's still involved with Y Combinator in California.

Shrivastava began developing Paladin Drones when he was finishing high school in Ohio. The summer before his senior year, a friend's house burned down. While nobody was injured in the fire, the home was destroyed, and Shrivastava spoke with the local firefighters. Tragically, the 911 call that alerted firefighters of the emergency was one of the 70 percent of calls that involved inaccurate location information.

"If they'd known the exact location, the house would've been saved," Shrivastava says. "A fire doubles every 30 seconds."

5 Houston-area companies named among world's most innovative for 2026

In The Spotlight

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned praise on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.

UH lands $11.8M for first-of-its-kind early language development study

speech funding

Researchers at the University of Houston have secured an $11.8 million grant from the National Institutes of Health to conduct a first-of-its-kind study of early language development.

Led by Elena Grigorenko, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Psychology, and research professor Jack Fletcher, the study will follow 3,600 children aged 18 to 24 months to uncover how language skills develop at this critical stage and why some children experience delays that can influence later growth.

The NIH funding will also support the development of the new national Clinical Research Center on Developmental Language Disorders at UH, which aims to bring experts from psychology, education, health and measurement sciences to study how children learn language.

“This will be the first national study to estimate how common late talking is using a large, representative sample of Houston toddlers,” Grigorenko said in a news release. “By following these children as they grow, we hope to better understand the developmental pathways that can lead to conditions such as developmental language disorder and autism.”

UH’s team will partner with the pediatric clinic network at Texas Children’s Hospital, where children will be screened for early language development, allowing researchers to identify those who show signs of delayed speech. Next, researchers will follow the cohort through early childhood to examine how language abilities evolve and how early delays may lead to later challenges.

The Clinical Research Center on Developmental Language Disorders will be the 14th national research center established at UH, and will include researchers from multiple UH departments, as well as partners at Baylor College of Medicine and the Texas Center for Learning Disorders.

“This level of investment from the National Institutes of Health reflects the significance of this work to address a complex challenge affecting children, families and communities,” Claudia Neuhauser, vice president for research at UH, said in a news release. “By bringing together experts from multiple disciplines and partnering with major health systems across the region, the project reflects our commitment to advancing discoveries that impact our community.”
