Two Houstonians on a mission to enable safe and equitable entrepreneurship on college campuses have launched a new beta platform and closed pre-seed funding.

Clutch, a digital marketplace startup founded by Simone May and Madison Long, closed its pre-seed round of funding at $1.2 million – led by Precursor Ventures and other partners such as Capital Factory and HearstLab. The investment from this round will support Clutch’s national open beta launch of its platform for brands and student creators nationwide and its continued investment in customer and product strategy.

“We are at this inflection point where marketing is changing,” May says in a press release. “We know that the next generation can clearly see that and I think a lot of marketing agencies are starting to catch on. We need to be prioritizing the next generation’s opinion because they are driving who is interested in what they buy. This upcoming generation does not want to be sold to and they don’t like inorganic, inauthentic advertisements. That’s why user generated content is so big, it feels authentic.” Continue reading.

Houston's new state-of-the-art academy FLAMA breaks ground at historic site

Groundbreaking Education

Houston’s newest school for arts and music broke ground in October in the city’s historic East End. The Frank Liu Jr. Academy for Music and Arts (FLAMA), a tuition-free charter school, will welcome students in pre-K through 8th grade next August.

Members of the Liu family, the school’s founding board members, elected officials, and East End community partners gathered at Buffalo Bayou Partnership’s historic Turkey Bend development for the official groundbreaking ceremony on October 8, which kicked off with a performance by the Kinder High School for the Performing and Visual Arts’ Mariachi group.

The new school is on a portion of the former Folgers Coffee Plant, located at 235 N. Norwood St. OMA, an international architectural firm known for its approach to urbanism, cultural projects, and adaptive reuse, is transforming the 1930s plant into a state-of-the-art educational facility.

“We’re excited to celebrate this milestone for FLAMA and look forward to seeing the transformation of the historic Folgers plant into a new home for music and arts education,” said Jason Long, one of the firm’s partners. “Like fine-tuning an instrument, our design recalibrates the existing industrial structure into an open, connected, and expressive environment for learning. FLAMA will be a new learning environment that builds on the character of the existing building while giving it new life for the community.”

Unfolding across three stories, the school draws inspiration from Montessori education principles, which prioritize openness, independence, and collective learning through shared “neighborhoods.”

It all begins when students, families and guests enter through a private courtyard. The welcoming space will change the building’s original industrial facade into a brightly colored, kid-friendly spot, complete with yellow and green blocks spelling out the school’s name. The original windows will be restored to preserve the building’s historic character and upgraded to meet contemporary energy standards. Similarly, all of the school’s classrooms are located around the building’s perimeter, providing an abundance of natural light.

Inside, FLAMA’s three stories are divided so that younger students will find their classrooms at the school’s base, and they will move upward through the school as they progress through grade levels. The ground level has a common area for younger kids that could host drum circles, movement classes, or “breakout play.”

Children in first and second grade have their own larger open space, with an eye-catching staircase, that's inspired by the curve of a French horn. The space lends itself to everything from small gatherings to performances by the school’s early musicians.

As students progress through third grade and up, they’ll find FLAMA’s upper floors created to meet their growing artistic and intellectual needs. One example is the open library, a shared spot for students in third through fifth grades. It has flexible furniture that can transform the space into a place for group study and project work, as well as one that can host after-school activities. Directly above this library is a second common room for middle schoolers where students in sixth, seventh, and eighth grades can study.

These two libraries are connected by an F-shaped floor opening that references both the F-hole of a string instrument and the forte symbol. Musicians know this curly f as a note indicating them to play a passage with strength. That could easily be a metaphor for the school itself, which will combine high-quality education with rigorous academics. This visual cue emphasizes FLAMA’s desire for music and art instruction to amplify learning across reading, writing, math, and science.

“This will be a place where children can discover their talents, families can find opportunities close to home, and music and art can open the doors to a stronger education,” said Congresswoman Sylvia Garcia, who attended the groundbreaking. “I know how much it matters when someone brings opportunity within the reach of a child.”

Dr. R. Scott Allen, FLAMA’s founding superintendent and former principal of Kinder HSPVA, spoke about the school’s vision to pair a rigorous, engaging academic opportunity with deep immersion in music and visual arts.

Congressman Christian Menefee, State Senator Carol Alvarado, and Houston City Councilmember Mario Castillo also delivered remarks at the ceremony, speaking about the school’s power to not only transform Houston’s Second, Third, and Fifth Ward communities, but also bring incredible education opportunities to students. Former Mayor Annise Parker, former State Board of Education Member Staci Childs, State Representative Christina Morales, and Houston City Councilmembers Joaquin Martinez and Sallie Alcorn also attended the event.

“In this city, known for our undeniable contributions to music and arts, the gap has never been ability or talent; it has always been opportunity, and opportunity can be built,” said Kirby Liu, who spoke at the groundbreaking, memorializing his late brother’s vision of arts education for the youngest Houstonians. “When it comes to opportunity being foreclosed on our children, we will try like hell to bust those damned doors down.”

The Frank Liu Jr. Foundation has pledged $20 million in financial support during FLAMA’s first years of operation. Applications are now open for kindergarten and first grade for the 2027-2028 school year.

New manufacturing facility breaks ground at NASA’s Johnson Space Center

making space

HITT Contracting has broken ground on NASA’s Applied Spaceflight Fabrication Facility (ASFF) at Johnson Space Center, the Washington, D.C.-based construction firm announced late last month.

The project, known as Building 70, will house a high-bay machine shop to support component production for future NASA space missions, according to HITT. The 37,625-square-foot building is the first part of a larger goal to create an engineering complex that unites assembly space, lab capabilities and manufacturing at JSC. It will consolidate machining equipment and operations that are currently spread across multiple campus buildings into one location.

The project broke ground in October at JSC’s Historic District. The Houston Business Journal reports construction is expected to wrap in August of 2028.

“This project will modernize facilities that support America’s space missions,” PJ Ross, chief financial officer at HITT, said in a LinkedIn post. “Proud of our team and partners as we begin construction that will advance aerospace testing and innovation.”

HITT Contracting is one of seven companies awarded infrastructure contracts by NASA earlier this year for work at JSC. According to NASA, the construction contracts “[support] up to $300 million in upgrades to mission‑support facilities, utilities, and equipment across the NASA Johnson campus.”

Construction Drive reports that HITT will also renovate Building 13 South on the JSC campus as part of the $300 million initiative.

“Building for precision manufacturing starts with understanding how the space needs to perform,” Todd Hudson, vice president at HITT Contracting, added in the release. “Our team brings the technical expertise and collaborative approach to deliver a facility that meets the Johnson Space Center’s needs today and supports the next generation of spaceflight innovation. We’re proud to continue our partnership with NASA.”

NASA also recently announced awards as part of its expanded Moon Base exploration, science and infrastructure capabilities. Houston-based Intuitive Machines and seven other spacetech companies, including SpaceX, Blue Origin and Firefly Aerospace, were selected to receive funding.

The awards are part of the next phase of NASA’s CLPS (Commercial Lunar Payload Services) initiative, which will grant the companies a combined total of up to $10 billion over 10 years.

Intuitive Machines and Webster-based MEI Technologies were also awarded contracts this past summer from NASA to develop robots for exploring the surface of Mars. Read more here.
