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.

"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.

Rice University MBA programs rank among top 5 in prestigious annual report

top of class

Rice University’s Jones Graduate School of Business MBA programs have been ranked among the top five in the country again in The Princeton Review’s 2025 Best Business Schools rankings.

The university's MBA program in finance earned a No. 3 ranking, climbing up two spots from its 2024 ranking. Finance MBA programs at the University of Virginia's Darden Graduate School of Business and New York University's Leonard N. Stern School of Business were the only ones to outrank Rice, claiming No. 2 and No. 1 spots, respectively.

Rice's online MBA program was ranked No. 5, compared to No. 4 last year. Indiana University's Bloomington Kelley School of Business' online program claimed the top spot.

“These rankings reflect the commitment of our faculty and staff, the drive and talent of our students and the strong support of our alumni and partners,” Peter Rodriguez, dean of Rice Business, said in a news release. “They are exceptional honors but also reminders — not just of our top-tier programs and world-class faculty and students but of our broader impact on the future of business education.”

Rice also ranked at No. 6 for “greatest resources for minority students."

The Princeton Review’s 2025 business school rankings are based on data from surveys of administrators at 244 business schools as well as surveys of 22,800 students enrolled in the schools’ MBA programs during the previous three academic years.

"The schools that made our lists for 2025 share four characteristics that inform our criteria for designating them as 'best': excellent academics, robust experiential learning components, outstanding career services, and positive feedback about them from enrolled students we surveyed," Rob Franek, The Princeton Review's editor-in-chief, said in a press release. "No b-school is best overall or best for all students, but to all students considering earning an MBA, we highly recommend these b-schools and salute them for their impressive programs."

Rice's finance program has ranked in the top 10 for eight consecutive years, and its online MBA has ranked in the top five for four years.

Rice and the University of Houston also claimed top marks on the Princeton Review's entrepreneurship rankings. Rice ranks as No. 1 on the Top 50 Entrepreneurship: Grad list, and the University of Houston ranked No. 1 on Top 50 Entrepreneurship: Ugrad. Read more here.

Houston named ‘star’ metro for artificial intelligence in new report

eyes on AI

A new report declares Houston one of the country’s 28 “star” hubs for artificial intelligence.

The Houston metro area appears at No. 16 in the Brookings Institution’s ranking of metros that are AI “stars.” The metro areas earned star status based on data from three AI buckets: talent, innovation and adoption. Only two places, the San Francisco Bay Area and Silicon Valley, made Brookings’ “superstar” list.

According to Brookings, the Houston area had 11,369 job postings in 2024 that sought candidates with AI skills, 210 AI startups (based on Crunchbase data from 2014 to 2024), and 113 venture capital deals for AI startups (based on PitchBook data from 2023 to 2024).

A number of developments are boosting Houston’s AI profile, such as:

Brookings also named Texas’s three other major metros as AI stars:

  • No. 11 Austin
  • No. 13 Dallas-Fort Worth
  • No. 40 San Antonio

Brookings said star metros like Houston “are bridging the gap” between the two superstar regions and the rest of the country. In 2025, the 28 star metros made up 46 percent of the country’s metro-area employment but 54 percent of AI job postings. Across the 28 metros, the number of AI job postings soared 139 percent between 2018 and 2025, according to Brookings.

Around the country, dozens of metros fell into three other categories on Brookings’ AI list: “emerging centers” (14 metros), “focused movers” (29 metros) and “nascent adopters” (79 metros).
