A Houston-based startup developing AI-powered humanoid robots for manufacturers and other businesses has raised more than $10 million in pre-seed funding less than a year after its founding.

Nic Radford, co-founder and CEO of Persona AI, declines to disclose the amount raised. However, he tells InnovationMap that it was an eight-figure total.

While not providing names, Radford says Persona AI’s first outside investors include VC firms, institutions and high-net-worth individuals in the U.S., London and Singapore. One of the high-net-worth investors was among the first employees at SpaceX, Elon Musk’s Brownsville, Texas-based aerospace company, according to Radford.

No Houston investors have participated in the funding round yet. However, Radford says he’s working on bringing aboard one local investor before the round closes.

“Houston’s the perfect city to do a company like this in,” Radford says. “It’s just not the perfect investor climate, but it's the perfect city from a customer aspect.”

Persona AI’s pre-seed funding comes amid a dramatic surge in investment capital chasing AI startups. Global funding for AI-related companies exceeded $100 billion in 2024, up more than 80 percent from the 2023 total, Crunchbase data shows.

Radford and co-founder Jerry Pratt, the startup’s chief technology officer, bootstrapped Persona AI. The third co-founder, Jide Akinyode, serves as Persona AI’s chief operating officer. Radford and Akinyode helped develop NASA’s six-foot-two-inch Valkyrie humanoid robot and both are former employees of Webster-based Nauticus Robotics, a provider of autonomous subsea robots.

Persona AI launched last June in what Radford calls “anti-stealth mode.” The startup is close to announcing its first customer, which does business in the industrial sector. Persona AI expects customers to take delivery of its first robot in 18 to 24 months, Radford says.

Persona AI will operate primarily as a robotics-as-a-service provider, with the company retaining ownership of the lifelike robots and selling the labor that they supply. Radford says the startup’s robots will help alleviate a shortage of skilled labor in sectors like manufacturing.

A report released last year by consulting firm Deloitte and the Manufacturing Institute declared that as many as 1.9 million manufacturing jobs in the U.S. could go unfilled between 2024 and 2033 due to a skills gap and a tight labor market.

Persona AI competes in a market with enormous potential. In November, analysts at Citi Global Insights projected that the global market for humanoid robots could soar to $7 trillion by 2050, with 650 million of the robots tackling all sorts of jobs.

Radford says Personal AI is developing a “rugged” five-foot-eight-inch humanoid robot that’s able to survive tough indoor and outdoor conditions and take on tasks like carting around sheet metal, tending to metal-stamping machines, moving storage bins and handling order fulfillment. He likens his company’s robot prototype to a Ford F-150 pickup truck, compared to the less-sturdy versions produced by robotics competitors, which he calls the Toyota Camry or Volkswagen Beetles of the field.

Radford says he and his team “are building a really compelling startup in one of the hottest markets and one of the greatest cities.” Employees work at Persona AI’s headquarters in Houston or its satellite office in Pensacola, Florida, where Pratt is located.

“We don’t hire anybody that’s not a rock star or superstar,” says Radford, “and I think the city is going to benefit tremendously from our efforts at Persona.”

Radford saw his last company, Nauticus Robotics, from founding to IPO, left the company in January and previously told InnovationMap that he couldn't get the idea of advancing humanoid robotics out of his head. Read more here.

Houston innovator bets on humanoid robotics with new startup

back in the founder seat

For his next act, Houston entrepreneur Nicolaus Radford has started — in what he describes as an "anti-stealth" capacity — a new company that hopes to bring humanoid robotics out of science fiction novels and into manufacturing floors.

Radford, who saw his last company, Nauticus Robotics, from founding to IPO, left the company in January. He tells InnovationMap that he started receiving some compelling offers at other robotics companies, but none of them felt like a fit. However, he just couldn't get the idea of advancing humanoid robotics out of his head.

"Humanoids are the holy grail of all of robotics," Radford says. "It's what every science fiction writer's always dreamed about.

"It is the future," he continues. "And now with this generative AI moment of 2022 where these machines look a lot more capable, flexible, reprogrammable — they can reason in real time. That's a huge deal."

Radford says he got a call from his friend, Jerry Pratt, who was the CTO at humanoid robotics company Figure AI. Pratt and Radford both worked in robotics at NASA and each have decades of experience in the tech world. The conversation really sealed the deal for Radford, and the two officially launched Persona AI in a LinkedIn post that Radford says shocked him with how much interest the community had.

Radford says that with all this interest, he wants to open up the company to more co-founders than just himself and Pratt, who's based in Florida.

"We're going to give a significant amount of the company out to the early joiners, more so than is probably typical," Radford says. "And it's because we know it takes a village, and we want to highlight that to everybody."

"We're trying to crowdsource the company," he continues. "We've coined that we're anti stealth."

Specifically, Radford says he's looking at growing the team to about 25 people in the next year, alongside raising early funding. He's looking for people with a diverse tech background with well-rounded experience.

"Robotics and humanoids in particular are just so multidisciplinary," Radford says. "Humanoids are a hundred-thousand-piece puzzle, and you're trying to put this puzzle together."

And for Radford, assembling that puzzle in Houston is of utmost importance. The company is headquartered here, and Radford is currently working with The Ion to set up an office there.

"We're exceptionally excited to put (the company) in Houston," he says. "It would be incredible for the city — there's a lot of industrial manufacturing here and a lot of warehousing. ... I still have this desire to shine a light on Houston's tech scene because I believe it is unsung, underappreciated, and quite capable."

The potential for this technology is huge — Radford estimates it as a $3 trillion market — but the first industry he plans on tackling is automotive, but he also sees promise in the medical, energy, and home industries.

"We think automotive is going to be a first-mover market. There's a lot of publicly announced partnerships between advanced robotics companies and humanoid companies and automotive," he says. "These folks are showing a willingness to put something out in the press that says they're developing a humanoid or piloting a humanoid. That's huge.

With this expressed interest, technology advancement, and large labor shortage, Radford is convinced now is the time for humanoid robotics — and for Persona AI.

"We're at a technology tipping point where it makes sense that these machines can do this, and there's an investment community willing to finance it," Radford says. "I think the first time in all of robotic history we're closer than we've ever been to making this a reality."

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
