9 innovation & networking events for Houstonians to attend at SXSW 2025

South by Southwest, Austin's signature hybrid music, film and interactive festival, returns to the Texas capital this month, running March 7 through 15.

In the business and innovation sector, the festival fuses together SXSW Edu for educators at the beginning of the week and SXSW Interactive, which is one of the largest gatherings in the world of innovators, technologists, artists, startups, investors and policy-makers. SXSW is a powerful international magnet for creators and the people who serve them.

I started coming to Austin for SXSW in 1999, a few years after the Interactive portion (nicknamed "Spring Break for Nerds") launched and when the entire conference of 6,000 attendees fit into the Austin Convention Center. Back then, you could rub shoulders with famous bloggers who challenged established tech journalists in the hallways, multimedia artists handing out bootleg CD-ROMS, and hard-core geeks setting web standards and laws related to technology that we enjoy today.

SXSW, like Austin itself, has grown up quite a bit in the last two decades and has fended off the common Austin refrain of "It was better X years ago," as everything has become more commercial, less "authentic" and more expensive. SXSW officially sells tickets or badges for $2295.00 at the Platinum level (with cheaper options as well) providing access to stand in lines with hundreds of your friends for the most popular keynotes and panels.

One critical tradition of SXSW and part of the relentless motivation to "Keep Austin Weird" is the dozens of unofficial side events that pop up during the event all across the city. These unofficial events and activations typically provide networking opportunities fueled by the draw of internet-famous speakers, free food, and free alcohol. As SXSW has grown exponentially, it still seems to retain its charm and quirkiness as not quite a music festival, like Bonnaroo or Lollapalooza, nor a film festival like Sundance or Tribeca, and certainly not a traditional tech conference like CES. I like to think of it as a Carnival with many things to do and see but without a specific agenda or outcome. Since COVID and the financial market retraction, these parties and happy hours have become a lot more restrained, but they still exist if you know where to look.

This article is designed to guide you through the highlights, both official and unofficial, of SXSW with a focus on professional business development with a strong bent toward networking with tech startups. Here's what not to miss.

These are the Houston companies headed to MassChallenge Texas in Austin

Texas road trip

It's the second cohort for Boston-based MassChallenge Texas in Austin, and this year's 74 selected finalists are well represented by Houston.

"Coming from an extremely competitive application pool, the startups in our second Austin-based cohort represent an incredibly high bar of creativity and talent, all of who are poised to make an impact," says Mike Millard, managing director of MassChallenge Texas, in a release. "This year's program will offer the finalists innovation at scale with direct access to resources through our programs in Houston and Austin, and our community around the state. Through these channels, startups will have more opportunities to test and validate their ideas with partners while creating meaningful engagements to help them get to pilot or pivot as fast as possible."

While there is the upcoming MassChallenge Texas inaugural Houston cohort, these seven companies opted for a spot in the Austin-based cohort where the stakes are higher and cash prizes are on the line — $500,000, the largest equity-free cash prize in Texas, to be precise. (Houston's inaugural set of prizes reportedly don't included money.)

These are seven of the Houston-related companies that will be trekking back and forth to Austin from June until October.

It's crewcollar's mission to optimize hiring for industrial and blue-collar jobs, simplifying the entire process from curated job posts to paperwork filing. The company is based just outside of Houston in Missouri City.

"We are super excited to be joining MassChallenge Texas, and know that this experience will help us take it to the next level," says M. Siler, CEO and founder, in a release.

Houston-based GotSpot is Reda Hicks solution to finding temporary space quickly and easily — in a way that benefits all sides of the transaction. The model is like AirBnb, but for retail, meeting, and even emergency space. The corporate lawyer has grown the platform over the past few years and the MassChallenge opportunity is another move in the right direction. Click here to read more about Hicks and GotSpot.

Grant Source is like the magic genie to help organizations find funding through grants and opportunities. The Houston startup has a database of opportunities and can help match businesses with appropriate grants to apply to — all within the Grant Source mobile app.

Guzo is the tool every traveler has dreamed up. The Houston-based app connects travelers — not just in the planning phase — but throughout the travel process. The company was created by two brothers — Joshua and Gordon Taylor — and is the recreation of Croozen, formerly a long-distance carpool app.

"One of the things that got Gordan and I excited in the beginning of Croozen was just the idea of someone else in the car with you and that shared experience," Joshua Taylor tells InnovationMap in a previous interview about revamping Croozen as Guzo. "Looking past that, just being focused on the car was hindering us. Let's divorce the car and focus on travel as a whole."

Practice makes perfect, and surgeons should be as close to perfect as possible, right? Lazarus 3D uses 3D printing to make realistic body parts and organs so that surgeons can rehearse their surgeries before ever slicing into a patient. The company is conveniently located in the Texas Medical Center.

Pilot Plus

The trucking industry needs a rebrand. It's a tireless job that's go-go-go, and the unappealing nature of the career isn't ideal. Pilot Plus puts the humanity back in the process that benefits the driver and makes for bragging rights for the company employing the trucker. The logistics company allows for a system of drivers that work together for the long haul so that drivers can actually spend time resting in their own homes.

Topl

Topl's MassChallenge bio lists their HQ in the Netherlands, but the blockchain startup founded by three Rice University alumni has some of its operations right here in town. Topl has a goal of using blockchain technology to connect the dots and enhance transparency in various applications from retail to even being able to track the success of investments or scholarships.

"We are a generation that wants a story," Kim Raath, president at Topl, tells InnovationMap in a previous interview. "We want an origin, and don't want to be fooled. And, because you might be able to reduce the cost by having this transparency, you might be able to bring down the cost on both sides."

Houston healthtech startup raises $30M to scale surgical healing gel

fresh funding

Houston-based healthtech startup TYBR Health has raised a $30 million Series A round to scale its B3 GEL System, which helps protect tendons from scarring after surgery.

The round was led by Minneapolis-based Vensana Capital and Cleveland-based Mutual Capital Partners, with participation from Denver-based Neovate Capital Partners and existing investors, according to a news release from the company.

TYBR Health said it plans to use the funding to broaden the B3 GEL System's clinical applications, expand commercialization and conduct studies to evaluate its ability to protect tissue and improve healing outcomes.

"Surgeons are exceptionally good at the structural repair, but the biology that follows is what determines how it heals. That part of the equation has gone largely unaddressed ... There's a shift underway across surgical specialties, from focusing almost entirely on the mechanical repair to also weighing the biological conditions that repair needs to succeed," Tim Keane, co-founder and CEO of TYBR Health, said in the news release. "This financing lets us reach more surgeons and generate the clinical evidence to move that shift forward."

As part of the financing round, Greg Banker of Vensana Capital and Liz Todia Zambory of Mutual Capital Partners will join the TYBR board, alongside independent director Aaron Smith.

"TYBR Health is addressing a gap surgeons have lived with for a long time, with a product that fits the way they already work," Zambory, principal at Mutual Capital Partners, added in the release. "We're excited to co-lead this round and support the company's growth."

TYBR was founded in 2020 and originated from the TMCi’s Biodesign fellowship and participated in the TMC's Accelerator for HealthTech. Its B3 GEL System is a flowable extracellular matrix hydrogel designed to protect tendons, ligaments, muscles, and the surrounding soft tissue while they heal from orthopedic surgery. It received FDA 510(k) clearance last June and launched an Australian clinical trial in the fall.

The B3 GEL System has been used in hand, wrist, shoulder, foot and ankle, and sports medicine procedures since it launched, according to the company, and was first used in the clinical setting earlier this year by Dr. Tammam Hanna with Texas Tech University Health Sciences Center.

Houston space companies win NASA funding to build Mars exploration robots

mission to mars

Two Houston-area spacetech companies have landed a portion of a $17 million award from NASA to develop robots for exploring the surface of Mars, the agency announced this month.

Houston-based Inuitive Machines and Webster, Texas-based MEI Technologies, which does business as Aegis Aerospace, were among the seven companies selected to receive the funding from NASA's Science Transport and Robotic Innovation for Deployment and Exploration (STRIDE) initiative.

According to the release from NASA, the companies are tasked with creating "innovative mobility systems" that would allow future Mars missions to access more challenging terrain and difficult-to-reach regions of the planet, and to travel farther distances. NASA estimated that the work will begin this fall.

NASA solicited proposals for participants in the STRIDE initiative in January. The seven named companies are the first selected to participate in the program.

The additional five companies to receive STRIDE funding include:

"STRIDE demonstrates NASA’s commitment to strong public-private partnerships, allowing the agency to explore new approaches for Mars surface exploration while identifying key capability gaps and development needs for commercial systems that could operate and traverse realistic Martian environments," NASA shared in the announcement.

Last month, Intuitive Machines was awarded $148.3 million to deliver its Nova-C lander to the moon. The funding was part of $600 million the space agency awarded to three companies as part of its Moon Base Program and was Intuitive Machines' sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program. Astrobotic was also one of the companies to land funding for the Moon Base program, as well as Austin-based Firefly Aerospace.

Around the same time, Firefly Aerospace was awarded a $13 million subcontract from NASA’s Jet Propulsion Laboratory to develop technology for NASA’s SkyFall mission to Mars. The mission aims to deploy three Mars helicopters to "perform science and demonstrate airborne subsurface mapping and resource prospecting on the planet." Read more here.
