taking flight

Houston-based Paladin Drones has debuted Knighthawk 2.0, its new autonomous, first-responder drone.

The drone aims to strengthen emergency response and protect first responders, the company said in a news release.

“We’re excited to launch Knighthawk 2.0 to help build safer cities and give any city across the world less than a 70-second response time for any emergency,” said Divyaditya Shrivastava, CEO of Paladin.

The Knighthawk 2.0 is built on Paladin’s Drone as a First Responder (DFR) technology. It is equipped with an advanced thermal camera with long-range 5G/LTE connectivity that provides first responders with live, critical aerial awareness before crews reach the ground. The new drone is National Defense Authorization Act-compliant and integrates with Paladin's existing products, Watchtower and Paladin EXT.

Knighthawk 2.0 can log more than 40 minutes of flight time and is faster than its previous model, reaching a reported cruising speed of more than 70 kilometers per hour. It also features more advanced sensors, precision GPS and obstacle avoidance technology, which allows it to operate in a variety of terrains and emergency conditions.

Paladin also announced a partnership with Portuguese drone manufacturer Beyond Vision to integrate its Drone as a First Responder (DFR) technology with Beyond Vision’s NATO-compliant, fully autonomous unmanned aerial systems. Paladin has begun to deploy the Knighthawk 2.0 internationally, including in India and Portugal.

The company raised a $5.2 million seed round in 2024 and another round for an undisclosed amount earlier this year. In 2019, Houston’s Memorial Villages Police Department piloted Paladin’s technology.

According to the company, Paladin wants autonomous drones responding to every 911 call in the U.S. by 2027.

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."

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."
