Houston-based Energytech Nexus has rebranded.

The cleantech founders community will now be known as Energytech Cypher. Organizers say the new name was inspired by the Arabic roots of the word cypher, ṣifr, which is also the root of the word zero.

"A cypher is a key that unlocks what's hidden," Nada Ahmed, co-founder and chief revenue officer of Energytech Cypher, said in a news release. "And zero? Zero is where every transformation begins, the leap from 0 to 1, from idea to reality, from potential to power. We decode the energy transition by connecting the right founders, the right capital, and the right corporate partners at the right time, because the most important journey in energy is the one that takes you from nothing to something."

Energytech Nexus has rebranded to Energytech Cypher.

Co-founder and CEO Jason Ethier says that the name change better reflects the organization's mission.

"The energy transition doesn't have a technology problem. It has a connection problem," Ehtier added in the release. "The right founders exist. The right investors exist. The right partners exist. What's been missing is the infrastructure to bring them together—to decode the complexity, remove the friction, and make sure the best technologies find the markets that need them. That's what this community has always done. Energytech Cypher is the name that finally says it."

Energytech Cypher, previously known as Energytech Nexus, was first launched in 2023 and has grown from a podcast to a 130-member ecosystem. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, Solidec and many others.

It is known for its flagship programs like the Pilotathon, which connects founders with industry partners for pilot opportunities. The event debuted in 2024.

Energytech Cypher also launched its COPILOT Accelerator last year. The accelerator partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. The inaugural cohort included two Houston-based startups and 12 others from around the U.S.

It also hosts programs like Liftoff, Energy Tech Market, lunch and learns, CEO roundtables, investor workshops and international partnership initiatives.

Last year, Energytech Cypher also announced a new strategic ecosystem partnership with Greentown Labs, aimed at accelerating growth for clean energy startups. It also named its global founding partners, including Houston-based operations such as Chevron Technology Ventures, Collide, Oxy Technology Ventures, and others from around the world.

Venus Aerospace closes $91 million Series B to scale hypersonic engine

flight funding

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were named to the World Economic Forum's Technology Pioneers community earlier this summer. Read more here.
