A Houston-based medtech startup with an innovative tool that's aiming to transform lung cancer intervention has closed its series A extension round.

Prana Thoracic announced an additional $3 million in funding, a raise that was oversubscribed by 30 percent, reports the company. The company's series A originally closed in March 2023 at $3 million. In August of 2022, the company secured $3 million in grant funding.

"We are grateful for the overwhelming support from our investors in this financing round. Their confidence in our mission and plan is motivating,” Joanna Nathan, CEO and co-founder of Prana Thoracic, says in a news release. “This additional funding will enable us to accelerate our efforts in bringing precision surgical solutions to lung cancer patients worldwide.”

The extension included participation from new investors, including cultivate(MD), GenHenn Capital, and Houston Angel Network, as well as from prior lead investor New World Angels. Existing investors — Johnson & Johnson Development Corp, Texas Medical Center Venture Fund, and the Cancer Prevention & Research Institute of Texas (CPRIT) — also support the company.

"We are excited to support Prana Thoracic in their mission to improve lung cancer treatment. Their innovative approach has the potential to significantly impact patient outcomes," says Dr. R. Sean Churchill, managing director of cultivate(MD), in the release.

The additional funding will support the company as it advances through its clinical and regulatory plans.

“The team has made remarkable progress in developing this novel and minimally invasive technique for lung tissue excision, which has the potential to transform the diagnosis and treatment of early-stage lung cancer," adds Dr. Edward M. Boyle, founder and director at the company. "Beyond lung applications, they are pioneering new methods to use this technology for other soft tissues and are actively exploring integration with ablation and robotic systems, aligning with the future direction of these fields."

In 2022, Nathan joined the Houston Innovators Podcast to discuss her passion for Prana Thoracic's innovation. Listen to the episode below.

Houston VC funding surged in 2024, fueled by major Q4 activity

by the numbers

The venture capital haul for Houston-area startups jumped 23 percent from 2023 to 2024, according to the latest PitchBook-NVCA Venture Monitor.

The fundraising total for startups in the region climbed from $1.49 billion in 2023 to $1.83 billion in 2024, PitchBook-NVCA Venture Monitor data shows.

Roughly half of the 2024 sum, $914.3 million, came in the fourth quarter. By comparison, Houston-area startups collected $291.3 million in VC during the fourth quarter of 2023.

Among the Houston-area startups contributing to the impressive VC total in the fourth quarter of 2024 was geothermal energy startup Fervo Energy. PitchBook attributes $634 million in fourth-quarter VC to Fervo, with fulfillment services company Cart.com at $50 million, and chemical manufacturing platform Mstack and superconducting wire manufacturer MetOx International at $40 million each.

Across the country, VC deals total $209 billion in 2024, compared with $162.2 billion in 2023. Nearly half (46 percent) of all VC funding in North America last year went to AI startups, PitchBook says. PitchBook’s lead VC analyst for the U.S., Kyle Stanford, says that AI “continues to be the story of the market.”

PitchBook forecasts a “moderately positive” 2025 for venture capital in the U.S.

“That does not mean that challenges are gone. Flat and down rounds will likely continue at higher paces than the market is accustomed to. More companies will likely shut down or fall out of the venture funding cycle,” says PitchBook. “However, both of those expectations are holdovers from 2021.”

Houston space company lands latest NASA deal to advance lunar logistics

To The Moon

Houston-based space exploration, infrastructure, and services company Intuitive Machines has secured about $2.5 million from NASA to study challenges related to carrying cargo on the company’s lunar lander and hauling cargo on the moon. The lander will be used for NASA’s Artemis missions to the moon and eventually to Mars.

“Intuitive Machines has been methodically working on executing lunar delivery, data transmission, and infrastructure service missions, making us uniquely positioned to provide strategies and concepts that may shape lunar logistics and mobility solutions for the Artemis generation,” Intuitive Machines CEO Steve Altemus says in a news release.

“We look forward to bringing our proven expertise together to deliver innovative solutions that establish capabilities on the [moon] and place deeper exploration within reach.”

Intuitive Machines will soon launch its lunar lander on a SpaceX Falcon 9 rocket to deliver NASA technology and science projects, along with commercial payloads, to the moon’s Mons Mouton plateau. Lift-off will happen at NASA’s Kennedy Space Center in Florida within a launch window that starts in late February. It’ll be the lander’s second trip to the moon.

In September, Intuitive Machines landed a deal with NASA that could be worth more than $4.8 billion.

Under the contract, Intuitive Machines will supply communication and navigation services for missions in the “near space” region, which extends from the earth’s surface to beyond the moon.

The five-year deal includes an option to add five years to the contract. The initial round of NASA funding runs through September 2029.

Play it back: Houston home tech startup begins 2025 with fresh funding

HOUSTON INNOVATORS PODCAST EPISODE 272

One of the dozen or so Houston startups kicking of the new year with fresh funding is SmartAC.com, a company that's designed a platform that enables contractors in the HVAC and plumbing industries to monitor, manage, and optimize their maintenance memberships through advanced sensors, AI-driven diagnostics, and proactive alerts.

Last month, the SmartAC.com raised a follow-on round with support from local investor Mercury to continue growth and expansion of the product, which has evolved on many ways since the company launched in 2020, emerging from stealth with $10 million raised in a series A. In a May 2023 interview for the Houston Innovators Podcast, Founder and CEO Josh Teekell explained how he embraced the power of a pivot.

The company's sensors can monitor all aspects of air conditioning units and report back any issues, meaning homeowners have quicker and less costly repairs. While SmartAC.com started with providing the service and tech to homeowners directly, Teekell says he's had a greater interest in working with plumbers and HVAC companies who then deploy the technology to their customers.

"It became quite evident that homeowners don't care about air conditioning really at all until their system breaks," Teekell says on the show. "The technology is really built around giving those contractors as another way to gain a customer relationship and keep it."

Revisit the podcast episode below where Teekell talks about SmartAC.com's last raise.

SmartAC.com's previous round in 2023 — a $22 million series B — was used grow its team that goes out to deploy the technology and train the contractors on the platform.

"We've been very fortunate to get some of the biggest names in Houston on our cap table," Teekell says in the May 2023 conversation. "Since we're raising a bunch of money locally, everyone understands what a pain air conditioning can be."
