Houston tech startup Artemis has raised $6 million from 10 investors. The company offers an AI-supported platform that enables solar, battery storage and home improvement contractors to design, sell and finance energy projects.

Long Journey and Copec WIND Ventures co-led the round, with participation from angel investor Scott Banister, Coalition Operators, FJ Labs, Ludlow Ventures, Palm Tree Crew, Plug and Play Ventures, Shrug Capital and Tribeca Ventures.

To help propel growth, the company secured $10 million in financing last year (under its previous name, Monalee) from venture debt and growth credit provider Applied Real Intelligence. As Monalee, the company raised $16 million in venture capital.

The company was founded in 2022 as an installer of solar and battery storage projects. Five years later, the startup used in-house technology to establish its standalone software platform as it began pivoting away from installation. The company recently adopted the Artemis brand name.

Artemis says its platform saves time and money for installers of residential solar, battery storage, and energy projects. The platform combines an AI-powered design tool with embedded financing capabilities and compliance automation to create a single operating system.

The company says its customers report as much as a 72 percent reduction in software costs and up to 98 percent faster turnaround times. Thus far, more than 100 installers are using Artemis’ technology.

“Installers shouldn’t need six tools and a week of back-and-forth to sell a project," Walid Halty, co-founder and CEO of Artemis, said in a press release. “This funding gives us the fuel to scale our mission to compress design, financing, and compliance into a single flow so every installer can operate like a modern energy company. We’re not just speeding up deals, we're modernizing how distributed energy gets built.”

The Artemis platform, now available in the U.S. and soon to be launched in Latin America, caters to home improvement contractors, solar companies, lenders, and utilities.

“Artemis is transforming the complexity of distributed energy into elegant simplicity," added Arielle Zuckerberg, general partner at Long Journey.

Electric truck charging network expands to Houston-Dallas freight corridor

electric trucking

Greenlane Infrastructure, an electric public charging station developer and operator, is expanding outside of its home state of California and into Texas.

The Santa Monica-based company plans to launch its high-power charging sites along the Dallas–Houston I-45 corridor, which is one of the highest-volume commercial trucking routes in the country, according to a news release from Greenlane.

The sites will feature 6-8 pull-through lanes with chargers supporting combined charging system (CCS) and megawatt charging system (MCS) connectors that allow electric truck drivers to recharge their vehicles during standard rest periods. They will also offer tractor parking and charging, as well as operations that will allow for overnight stops.

Drivers can reserve chargers in advance, monitor charging activity in real time, and manage billing from the Greenlane Edge platform.

“Our customers are making commitments to electrify their fleets, and they need a charging network that can grow alongside them,” Patrick Macdonald-King, CEO of Greenlane, said in the release. “This is the first leg of the Texas triangle, one of the more important freight arteries in the country, so bringing high-power charging there is the next logical step in building a network that serves how freight moves across America.”

Greenlane is also expanding across the West Coast, with five locations under development in California and Nevada. It opened its flagship Greenlane Center in Colton, California, in April 2025. The company plans to open locations in Blythe, California, and Port of Long Beach this year.

Greelane was founded in 2023 as a joint venture between Daimler Truck North America, NextEra Energy Resources and BlackRock. It has secured partnerships with electric long-haul truck developer Windrose Technology, Velocity Truck Centers and Volvo Trucks North America.

Houston startup lands $1B from Blackstone and Halliburton, plans acquisition

power deal

Houston-based power generation startup VoltaGrid has nailed down a $1 billion equity investment from asset management heavyweight Blackstone and Houston-based oilfield services provider Halliburton.

The investment comes in two forms:

  • A $775 million primary capital raise
  • A $225 million secondary capital purchase from existing investors

VoltaGrid, founded in 2020, provides behind-the-meter mobile power generation equipment for data centers, microgrids and industrial customers.

Aside from the $1 billion investment, VoltaGrid has agreed to buy Propell Energy Technology, a VoltaGrid supplier, for an undisclosed amount. Propell offers a natural gas power generation platform for AI data centers. VoltaGrid plans to add two manufacturing plants at Propell’s facilities in Granbury, a Dallas-Fort Worth suburb.

The investment and acquisition deals are expected to close in mid-2026.

Funds managed by Blackstone Tactical Opportunities are contributing to the $1 billion investment. William Nicholson, managing director of Blackstone, called VoltaGrid “a highly differentiated platform addressing one of the most important infrastructure needs of the AI era: reliable, rapidly deployable power. This investment is a strong example of Tac Opps’ focus on providing flexible, scaled capital to exceptional entrepreneurs and businesses operating in Blackstone’s highest-conviction investment themes.”

Nathan Ough, founder and CEO of VoltaGrid, said in a release that the Blackstone investment “is a powerful endorsement of the platform we have built and the role VoltaGrid is playing in delivering the energy infrastructure of the AI era.”

Last October, VoltaGrid and Halliburton said they had forged a partnership to supply power for data centers around the world, with the Middle East picked as the initial target. Two months later, the companies said they had arranged the manufacturing of 400 megawatts of natural gas power systems that’ll be delivered in 2028 to support new data centers in the Eastern Hemisphere.

Jeff Miller, president and CEO of Halliburton, said his company’s investment in VoltaGrid “reflects our shared focus on long-term solutions for the world’s most demanding power environments, and advances VoltaGrid’s ability to deliver reliable, distributed power at scale.”
