For most of her career, Ana Amicarella has been the only person in the room who looks like her. But as CEO of Houston-based EthosEnergy, she's changing that.

"The energy sector for sure is highly dominated by men, but I think it's such an exciting environment," Amicarella says on the Houston Innovators Podcast. "What I try to do at every job that I go to is I try to increase representation — diverse representation and females in the company. And I measure that when I started and when I end. I want to be able to make a difference."

Amicarella joined EthosEnergy — which provides rotating equipment services and solutions to the power, oil and gas, and industrial markets — as CEO in 2019 a few years after it was in 2014 as a joint venture between John Wood Group PLC and Siemens Energy AG. Prior to her current role, she served in leadership roles at Aggreko an GE Oil and Gas. Read more.

A Houston company has closed its series B extension at $25 million.

MetOx International, which develops and manufactures high-temperature superconducting (HTS) wire, announced it closed a $25 million series B extension. Houston-based Centaurus Capital, an energy-focused family office, and New System Ventures, a climate and energy transition-focused venture firm, led the round with participation from other investors.

"MetOx has developed a robust and highly scalable operation, and we are thrilled to partner with the Company as it enters this pivotal growth stage," says John Arnold, founder of Centaurus, in a news release. "The market for HTS is expanding at an unprecedented pace, with demand for HTS far outweighing supply. MetOx is poised to be the leading U.S. HTS producer, closing the supply gap and bringing dramatic capacity to high power innovations and applications. Their progress and potential are unmatched in the field, and we are proud to support their growth." Read more.

As Texans continue to invest in electric vehicles, public charging needs to be able to meet an increased demand, according to Chris George, the United States co-lead at Octopus Electric Vehicles, who wrote a guest column for InnovationMap about the state's potential when it comes to EVs.

"As we look to the future of transport and energy, the synergy between NEVI and Tesla’s network should create a compelling narrative for those thinking about leasing an EV," he writes. "Combine that with exciting new battery tech and potential range improvements, fueled by West Texas wind and solar, Texas is positioned to be a great state for the EV industry." Read more.

Houston energy company announces new EV business arm

making moves

Houston-based energy retailer Octopus Energy U.S. is now getting its tentacles into the electric vehicle business.

Octopus Energy US on July 6 unveiled Octopus Electric Vehicles, whose first offering is EV Concierge. This new service will help customers lease an EV, and integrate smart charging and billing into their existing energy plan.

New and existing customers in Texas can apply for the beta leasing program at octoev.us. Employees of the program will help customers search for a new or used EV to lease, install an at-home EV charger, and adopt best practices for EV ownership.

“Interest in electric vehicles is at an all-time high. With Texas as the third-largest market for EVs and a global leader in energy, we will be positioned to help customers realize vehicle and energy savings all on one bill,” says Chris George, U.S. director of Octopus Electric Vehicles. “As fossil fuel continues to be impacted by inflation, it’s never made more sense to get an EV paired with smart charging to extract the lowest-priced energy from the grid.”

EV Concierge is paired with Intelligent Octopus, which lets customers access power when it is cheaper and greener while helping balance stability of power grid.

Octopus Electric Vehicles launched in 2018 in the United Kingdom, where parent company Octopus Energy Group is based. In the U.K., Octopus leases EVs, installs at-home chargers, provides EV tax breaks, and provides access to more than 250,000 public charging stations in Europe.

Customers of Octopus Electric Vehicles can lease 65 different EVs from 28 automotive brands.

“We’ve seen that consumers are looking for experts that can offer the full EV package to guide them through their journey,” says Fiona Howarth, CEO of Octopus Electric Vehicles. “With more EV models entering the market every month, and innovative tariffs like Intelligent Octopus making charging your car as easy as [charging] your phone, we only expect the transition to accelerate.”

The launch of EV Concierge comes just a year after Octopus Energy U.S. set up shop in Houston. Establishment of the Houston presence coincided with the company’s $5 million acquisition of Houston-based Evolve Energy.

Last month, Kraken Technologies, the software licensing arm of Octopus Energy Group, picked Houston for its U.S. headquarters.

Octopus Energy Group, valued at nearly $5 billion, entered the U.S. market in 2020. It supplies green energy to more than 3 million retail customers around the world.

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.”
