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.

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.

"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."

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
