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."

Bairitone Health

Bairitone Health is bringing anatomy imaging for sleep apnea to the home environment. The company's platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient. The system is currently in the research and development phase and is being used in clinical trials and studies.

The company was founded in 2022 in the Texas Medical Center's Biodesign program by CEO Meagan Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators. It raised a pre-seed round last year of $435,000.

Corveus Medical

Corveus Medical has developed a novel catheter device that allows cardiologists to perform a splanchnic nerve ablation, restoring the pressure balance in patients with moderate heart failure. Its pre-FDA-approved, minimally invasive solution deactivates a nerve that has been demonstrated to be a root cause behind heart failure progression, which allows physicians to treat patients who have traditionally had few options.

The company, formerly known as Caridian Medical, was founded in 2021 by CEO Tyler Melton and CMO Ishan Kamat. It has participated in incubators such as TMC Biodesign, Y Combinator, MedTech Innovator and Fogarty Innovation and was named one of the 10 most promising life science companies at Texas Life Science Forum in 2022. The company says it will move toward validation and verification testing for its device in Q4 of this year.

FibroBiologics

Regenerative medicine company FibroBioligics uses fibroblasts, the body’s most common type of cell, rather than stem cells, to help grow new cells to repair tissue and modulate the immune system. The cell therapies offer treatments for chronic conditions such as degenerative disc disease, multiple sclerosis and non-healing wounds.

The publicly traded company was founded in 2021 by CEO Pete O'Heeron. It opened a new 10,000-square-foot Houston lab earlier this year to scale up research efforts and pave the way for in-house manufacturing. The company says it plans to launch its first clinical trial for diabetic foot ulcers soon, representing the transition of its fibroblast technology to the clinic setting.

Koda Health

Koda Health has developed an advance care planning platform (ACP) that allows users to document and share their care preferences, goals and advance directives for health systems. The web-based platform guides patients through values-based decisions with interactive tools and generates state-specific, legally compliant documents that integrate seamlessly with electronic health record systems. The company also added kidney action planning to its suite of services for patients with serious illnesses last year.

Koda Health was founded out of the TMC's Biodesign Fellowship in 2020 by CEO Tatiana Fofanova, chief medical officer Dr. Desh Mohan, and chief technology officer Katelin Cherry. The company raised a $7 million series A earlier this year, and also announced major partnerships and integrations with Epic, Guidehealth, Medical Home Network, Privia Health and others.

NanoEar

NanoEar has miniaturized hearing aid technology so that it can be implanted across the eardrum, allowing adults with age-related hearing loss to enjoy better sound quality than they would with behind-the-ear hearing aids.

Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist, developed the technology, and the company was founded in 2016 with CFO Willem Vermaat and COO Michael Moore. The company participated in the TMC Innovation Institute in 2016. It has issued nine U.S. patents and performed successful human cadaver and animal proof-of-concept experiments. Its next step is developing a prototype.

Wellysis USA

Wellysis USA Inc. works to detect heart rhythm disorders with its continuous ECG/EKG monitor with AI reporting. Its S-Patch cardiac monitor is designed for extended testing periods of up to 14 days on a single battery charge. The device weighs only 9 grams, is waterproof and designed to be comfortable to wear, and is considered to have a high detection rate for arrhythmias. It is ideally suited for patient-centric clinical trials to help physicians make diagnoses faster, cheaper and more conveniently.

It was established in Houston in 2023 and participated in the JLABS SFF Program the same year. It closed a $12 million series B last year. It was founded by CEO Young Juhn, CTO Rick Kim, CFO JungSoo Kim and chief strategy officer JoongWoo Kim.

Port Houston reports emissions progress as cargo volumes climb

Greener growth

Port Houston’s initiatives to reduce emissions have shown some positive results, according to new data from the Port of Houston Authority.

Pulling from the Goods Movement Emissions Inventory (GMEI) report, which tracks port-related air emissions, Port Houston cited several improvements compared to the most recent report from 2019.

The port has seen total tonnage and container volumes increase by 16 percent and 28 percent, respectively, since 2019. However, greenhouse gas emissions have increased at a slower rate, growing only by 10 percent during the same time period, according to the data.

Additionally, emissions of nitrogen oxide fell by 7 percent, and emissions of particulate matter fell by 4 percent, despite adding 280 more pieces of cargo handling equipment.

“These results show that our emission-reduction efforts are working, and we are moving in the right direction,” Chairman Ric Campo said in a news release.

The Port Commission also recently approved items related to the $3 million U.S. Environmental Protection Agency Clean Ports Program (CPP) grant, which it received last year. The items will allow the port to work towards five new sustainability initiatives.

They include:

  1. An inventory of the port’s Scopes 1, 2, and 3 for greenhouse gas emissions
  2. A Port Area Climate Action Plan for the area and surrounding communities
  3. A CPP Truck Route Analysis
  4. Creation of the CPP Trucking Industry Collaborative
  5. Design of a customized website for Port of Houston Partners in Maritime Education, which is a non-profit leading maritime workforce development effort in local schools

Port Houston aims to be carbon neutral by 2050.
