Jeff James had the idea for a platform that allows musicians to engage with their audiences — specifically when it came to receiving tips. Right when he started working on the idea for PickleJar, an app-based, performer-focused platform where fans can conduct cashless tips, the pandemic hit.

"As the pandemic lingered on, we realized the project wasn't just about tipping or on-stage engagement, it's about something greater than that," James says on the Houston Innovators Podcast. "It's all the different ways how artists are being disenfranchised. We really set out on a mission to help artists make more money."

As distracting as the pandemic was at first to PickleJar, which officially launched in May of 2021, the company ended up having a huge opportunity to be a revenue stream for artists when they needed it most. The duo decided they had to build the company — even during the pandemic and uncertain times. Click here to read more and listen to the episode.

Clutch, a digital marketplace startup founded by Simone May and Madison Long, has fresh funding after closing its pre-seed round of funding at $1.2 million. 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.” Click here to continue reading.

Tarun Girish, founder and CEO of Sparks Spaces

Tarun Girish wanted to upgrade EV drivers' charging experiences. His idea became Sparks Spaces, a startup formed in 2021 looking to shake up the EV charging game — the company aims to elevate the experience of charging electric vehicles by focusing on the space between car and charger by creating an airport lounge-type space for drivers. These EV lounges would include luxury waiting areas, clean restrooms, high-end food options, and availability to utilize them 24/7.

“We’ve seen a huge issue in the EV charging space where the experience side has been neglected,” says Girish, founder and CEO of Sparks Spaces.

Currently, Sparks Spaces is operating out of The Ion and installed a charging point outside of the building to help collect insights into what drivers are needing and are wanting to learn more about their customer base. Click here to learn more.

Local startup to upgrade EV charging in Houston and beyond

seeing green

At 3 a.m. one night, just as he had many nights before, Tarun Girish found himself leaving his Houston apartment in search of an EV charger.

Once he located one, he would sit in his car for an hour and a half while his vehicle charged — with not much to do but wait.

But it was on this night he wondered if there was a way to use his previous hospitality experience to build a new kind of experience for EV drivers. He then developed his first iteration of a business plan — all while sitting in his driver’s seat.

Eventually, the company’s goal is to take forgotten buildings and transition them into becoming EV charging hubs.

“The Ion is giving us a lot of resources to make sure that we are tailoring the solution to the right problem,” he says. “We’ve learned how to build a frictionless experience where the driver scans a QR code, pays for the duration of the charging session and then plugs in.”

When Sparks Spaces scales out, the team is eyeing two locations inside The Loop — one in Montrose and one on Shepherd Drive. The design would focus on natural lighting, safety and security.

The startup went through the Smart City Ion Accelerator but will be applying to a couple more accelerators that have more exposure into the EV construction space.

“We’re trying to provide a brand consistent experience from the time a driver drives into a lot to the time they leave,” he says. “We’ll be providing all fast-charging and level 2 charging services for drivers and will be completely universal so that any EV can utilize us.”

Sparks Spaces is looking to raise a $1.1 million seed round that will focus on research and development, the case studies and the architectural designs for a prototype that can be implemented in its locations.

“We want to be the definition of charging and lounges and experiences should be the forefront of EV charging,” he says. “The average household who owns an EV expects a certain level of luxury and expectations on experience. They are used to airport lounges when traveling. We want to reflect that in the EV charging space.”

Axiom Space expands executive team with two C-suite hires

new leaders

Fresh off officially making Texas its legal headquarters, Axiom Space has named two new C-level executives.

The Houston-based spacetech company, which is developing the first commercial space station, announced earlier this month that it had appointed Zach Gitomer as its new chief financial officer and Erick Wegerer as chief information officer.

Gitomer served as vice president of investor relations and capital markets for Axiom from March to June of this year. Before joining Axiom, he held various leadership roles at Bank of America, Merrill Lynch, and Citi, where he supported technology and growth companies, according to Axiom.

"Building era-defining space infrastructure and pioneering the orbital economy is a complex endeavor that requires not just an audacious vision and stellar engineering talent, but the financial infrastructure, discipline, and capital strategy to match," Gitomer shared in a LinkedIn post. "I’m honored to take on this role ... I’m looking forward to partnering with the exceptional leadership team here at Axiom Space during a defining chapter for the company and commercial spaceflight broadly, as well as a crucial period for maintaining U.S. human presence in low-Earth orbit and leadership in space exploration."

Wegerer joins Axiom after most recently serving as CIO of Washington-based Insitu Inc., a subsidiary of Boeing that develops customized unmanned hardware for commercial, government and defense customers.

"My time at Insitu was defined by talented people, meaningful challenges, and work that mattered. I'm grateful for the teams, partners, and leaders who made progress there possible. Stepping into Axiom, I'm energized by the mission, the momentum, and the opportunity to help shape what's next," Wegerer shared.

The duo was celebrated on the floor of the New York Stock Exchange last week.

“We are pleased to welcome these exceptional leaders to the Axiom Space team," Axiom CEO Jonathan Cirtain added in the announcement. “Their strong record of helping complex organizations advance their strategic priorities will strengthen our executive team to further advance our core business objectives."

It's been a busy summer for Axiom. The company tacked on an additional $175 million to a previously announced capital raise, bringing the oversubscribed round to a total of more than $525 million, in June.

It also announced plans to open a Japanese subsidiary July 1. It tapped veteran Japanese astronaut Koichi Wakata to lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. It also shared plans to establish Axiom Space Switzerland, a wholly owned subsidiary based in Lucerne that is also expected to begin operations this summer.

Axiom also officially redomiciled its legal headquarters from Delaware to Texas last month. Read more here.

Houston hardtech accelerator names 8 founders to 2026 cohort

hardtech fellows

Hardtech-focused organization Activate has named 50 new members to its 2026 cohort of scientists, which includes eight startups joining Activate Houston.

Activate aims to support scientists at "the outset of their entrepreneurial journey." It partners with U.S.-based funders and research institutions to support its fellows in developing high-impact technology. Its fellows receive a living stipend, research and development funding, connections from Activate's robust network of mentors and access to a curriculum specific to the program for two years.

This year's fellows represent 41 companies from 22 U.S. cities and 11 states.

“This cohort clearly demonstrates that the next industry-defining companies won't choose between modern technology and deep science; they'll be built by combining both,” Cyrus Wadia, CEO of Activate, said in the announcement. “These are the scientists and engineers turning our most urgent global challenges into the companies that will deliver a more sustainable future.”

The Houston fellows are working across the energy, space, AI infrastructure and agriculture sectors. They include:

  • Sophie Clare Broun, founder of Anning Corporation, which is producing clean hydrogen by stimulating naturally occurring geologic deposits
  • Kathy Andersen, founder of Brint Tech, which builds optical sensing systems that quantify hydrogen for infrastructure operators
  • Dorsa Talebi, founder of Kinetiq Drive, which builds rare-earth-free, contact-free electric motors with wireless rotors for small appliances and heavy industry alike
  • Neethu Pottackal, founder of Nivera, which is developing natural, edible coatings made from agricultural byproducts to reduce food waste and extend the shelf life of fresh food
  • Jonathan Huffman, founder of Orbital Arc, which is shrinking spacecraft propulsion to a microchip powerful enough for deep space
  • Tim Lee, founder of Renesin, which develops advanced materials for faster, more efficient AI hardware
  • Joshua Livingston, founder of Selerra Separations, which is developing high-performance membranes that cut the cost and energy consumption of water treatment
  • Wenli Jiang, founder of SwieNitro Recovery, which is developing technology that converts nitrogen-rich waste streams into valuable fertilizer

"Home to the largest concentration of engineers in the United States and a dense ecosystem of Fortune 100 and Fortune 500 companies, Houston is uniquely positioned for scientists tackling large-scale industrial challenges. Activate Houston fellows are connected to the city's deep networks in energy, chemicals, and materials," Activate said in the announcement.

Activate named its inaugural Houston cohort in 2024. It has other hubs in Boston, New York, and Berkley, California—where Activate is headquartered. The organization also offers a virtual and remote cohort, known as Activate Anywhere. Nationally, it has supported 346 fellows and 276 companies since 2015.

Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion. The latest cohort is Activate Houston's third. Read more about the last year's cohort here.

Rice, Houston Methodist award $90K for cancer research projects

seed grants

Rice University’s Synthesis X Center, in partnership with the Houston Methodist Neal Cancer Center, announced earlier this month the organizations would award $90,000 in seed grant funding to two projects that could help fight cancer. One would ease the pain of chemotherapy, while the other could change the way the progression of leukemia is tracked.

“We’re excited to be collaborating with the Neal Cancer Center to support collaborative, novel and interdisciplinary proposals to improve cancer care and outcomes,” Han Xiao, Rice professor of chemistry and the director of the SynthX Center, said in a news release. “Together, we can achieve translational excellence.”

The projects

Chemotherapy is one of the most effective cancer treatments, but it can be hard on the body. The human body doesn’t like being injected with radioactive material, especially the skin around the injection point, which can become extremely irritated. For patients in long-term treatment, the skin irritation can be more than just a bother; it can lead to infections that are dangerous to a compromised immune system.

Angel A Marti, a professor of chemistry at Rice University, and Biana Godin, an associate professor of nanoscience at Houston Methodist Research Institute, are experimenting with metal nanoclusters as a way to block radiation at the injection site. The nanocluster could be applied in a cream or a gel on the skin, serving as a type of shield against the harsh radioactive material.

Meanwhile, Yuan Ma, an assistant professor of chemistry at Rice, and Shu-Hsia Chen, a professor of immunology at Houston Methodist Research Institute, are working with m6A. Discovered in the 1970s, m6A is the most prevalent chemical modifier found in mRNA in mammals. It is prevalent in many cancers, including leukemia.

Ma and Chen are working on measuring the amount of m6A in leukemia to see if it can determine the most effective cancer treatments. The team is also experimenting with ways to shut off m6A to see if it makes current leukemia treatments more effective.

Progress from SynthX

SynthX was first launched in April 2024 to turn research from Rice and Houston Methodist into real-world cancer treatments. Within a year, the center had secured $1.5 million in grant money to work on crossing the blood-brain barrier in brain cancer treatments. These latest awards show that SynthX Center continues to bridge the worlds of research and clinical practice.

“This collaboration reflects a shared commitment to team science in cancer research,” Daniela Matei, the director of the Houston Methodist Neal Cancer Center, added in the release. “These are the types of translational and pioneering projects that lead to transformation in patient care.”'

The SynthX Center awarded $90,000 in seed grants to three teams in 2025 and $80,000 to three teams in 2024.
