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 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.

This Houston innovator is making sure musicians are getting paid

houston innovators podcast episode 146

One night a few years ago, Jeff James found himself at a bar with a live musician serenading the crowd. And, living in an increasingly cashless society, he didn't have an easy way to show his appreciation by way of a tip.

He turned to Kristian Barowsky, a business colleague — the two were working on a project, and together they spitballed an idea for a cashless way to better engage with performing artists.

"The idea stuck with us, and, even though we were working on other projects, we decided that this really was an issue — the way that artists make money," James says on the Houston Innovators Podcast "It's such an ecosystem of scepticism, and everyone has their fingers in the pockets of these musicians."

James and Barowsky started working on the idea that would become PickleJar, an app-based, performer-focused platform where fans can conduct cashless tips — and they can be sure the artist is getting 100 percent of that money.

The duo wrote their first line of code two months before the pandemic hit and all of live music performances were postponed or streamed.

"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. "It's all the different ways how artists are being disenfranchised. We really set out on a mission to help artists make more money."

Now, PickleJar is a comprehensive engagement platform where artists can receive song requests and tips, but also sell tickets and merchandise and even crowdfund their next album.

"We decided that if we weren't going to solve this problem, then who was?" James says. "The negative impact the pandemic was having on artists — we had to be there waiting for them as we come out of the pandemic."

Over a year in now, PickleJar has over 2,500 artists on the platform who have generated over $1 million in income.

James shares more about the future of Pickle Jar on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

New Houston-based app tips the scales in favor of musicians and fans

tuned in to tips

Like so many business owners, Jeff James' inspiration for his innovative new music app PickleJar, came out of sheer necessity. Sitting in a bar in the buzzy Broadway district in Nashville, Tennessee, James, a serial entrepreneur, realized there had to be a better way to tip performing musicians.

"This young girl comes through the crowd carrying a Yeti bucket asking for 20 dollars for the band," James tells CultureMap. With no cash on hand, James donated via Square. "Sixty dollars later, I had so many questions: would she remember my name? Would she remember my songs? There's gotta be a better way to do this."

James, a former radio DJ and record label veteran, started scribbling his idea for a musician tipping app on a napkin. Two years later, PickleJar was sparked, James says, because "every musician we spoke to hates the way they're paid on these apps like Venmo and Facebook."

Pushing an "artist first," mission statement, PickleJar ensures that every musician utilizing the app keeps 100 percent of the money — something unheard of when James started the process two years ago. Fans donate to musicians on the app, and in turn, get five times that tip in proprietary digital currency called Pick Coins.

"If you tip 100 dollars to a musician, you get 500 Pick Coins," explains James, "that goes to buying tickets, merch, or VIP experiences on our app." Another artist-first perk: The artist also gets 500 Pick Coins in that scenario.

With its own e-commerce platform, PickleJar allows fans to use these Pick Coins for experiences, and musicians to use them for much-needed equipment. PickleJar has partnered with Austin-based Strait Music Company, which will provide musicians with instruments and gear. Musicians can create their own wish lists so that fans can directly contribute to the desired gear.

Fittingly, the company has partnered with local venues for themed nights. Buzzy bar McIntyre's Downtown will feature a tip-worthy Texas artist every Wednesday night in its PickLounge.

PickleJar also allows musicians to livestream. "On Facebook Live, data shows that only about eight to 10 percent of an artist's audience know they're live. On top of that, Facebook takes 30 to 40 percent of the tips." With PickleJar, 100 percent of an artists fans will be notified when the artists in livestreaming.

Fans can even donate directly to a musician's nonprofit of choice, something happening now during Hurricane Ida relief efforts. Numerous artists on PickleJar are raising funds for Ida assistance, James notes. "We really believe that a 'gratitude economy' is emerging," he says. "We wanted to create the easiest way possible for fans to say thank you."

That thank-you option also means fans can send direct messages, notes, and even pictures on the app, which, James acknowledges with a chuckle, could get very interesting.

Another musician-first nuance not found on other apps: PickleJar allows for "smart" splits, so that musicians are appropriately compensated for their specific contribution. An artist who wrote songs and drove the van to a gig, for example, can be funneled a higher percentage of tips than bandmates who contributed less.

James and his Houston-based tech team are also working on a TV channel on streaming devices, dubbed PickleJar Plus.

While one might be tempted to assume PickleJar is meant for those gig-to-gig, struggling musicians, James assures that the app is meant for every level, which he breaks down accordingly:

"Never-evers": These folks will never get signed, but use the app to get better
"Got talent, not signed": Artists can use PickleJar to build audiences and crowdfund
"I'm signed/labeled": Here, signed artists curate setlists which can be monetized via tips
"Idols": These artists are already brands. "Kenny Chesney can use this to make sure every dollar goes to a nonprofit," says James. Chesney's team can watch a meter, and when donations hit a specific dollar amount, Chesney can reward fans with their favorite song."

If all this seems to point to James one day managing and representing artists, James says that idea is not entirely off. PickleJar could one day be the world's biggest independent record label, he acknowledges, by the way it allows indies to promote themselves.

"We were in a meeting and the guy says, 'you're gonna change the entertainment world forever,'" James, recalls. "We hope so. We just want to build a relationship with artists — and put them first."

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.
