Here's what you missed at Houston House at SXSW. Photos courtesy

SXSW has descended on Austin, and while the two-week conference and festival is still going strong, the Greater Houston Partnership's Houston-focused activation has wrapped for 2022.

Houston House, which first originated last year in digital form in 2021, took place Sunday, March 13, and Monday, March 14. The nine panels and two nights of networking covered topics from energy transition and med tech to diversity in venture capital and innovation in aerospace.

For SXSW badge holders, some of the Houston House discussions are available online. However if you’re not out and about at SX and you missed these incredible panels, I spoke to four Houstonians after their discussions to dig a little deeper into some key points from the panels.

Here are the Houston Innovators I spoke with at SXSW:

  • Denise Hamilton, CEO of WatchHerWork
  • Kevin Coker, president and CEO, Proxima
  • Grace Chan, investment associate at bp Ventures
  • Dale Winger, managing director of Halliburton Labs

Listen to these conversations below — or wherever you stream your podcasts — and subscribe for weekly episodes, which will return to interview-style conversations featuring Houston guests next Wednesday.

SXSW panel: What Houston needs to do to develop as an equitable tech ecosystem

houston house

Houston has consistently been recognized as one of the most diverse cities in the country — but is that translating into equitable funding opportunities for diverse founders? A panel at SXSW this year discussed whether or not Houston's playing field is level for people of color within the innovation ecosystem.

"People do business with who they know — and who they like," says Felix Chevalier, co-founder of Urban Capital Network, when the panel was asked where the disconnect is with funding diverse founders. "I think it boils down to a lack of exposure and a lack of relationships."

Chevalier was joined by Jesse Martinez of Resolved Ventures and VamosVentures and Denise Hamilton of WatchHerWork, who moderated the discussion, which was hosted in the Greater Houston Partnership's Houston House on Sunday, March 13, at SXSW in Austin.

"We have to look at the pipeline — what the existing ecosystem looks like," says Martinez, who leads the LatinX Alliance, an organization that's relocating its operations to Houston. "We have new funds, new diverse GPs, and we have more investors — and we're building talent. ... We are making great strides, but we still need more of us to be funding our diverse founders."

The key to the equation, the panelists agreed, is education and programming — both for potential investors, like UCN does with its hands-on support for its diverse investor base, and for founders of color who might be more hesitant to plunge by starting a company.

"The way you start to dissolve that fear for folks, for example, who may be in a corporate space but may want to spread their entrepreneur wings, is to just get involved with the ecosystem," Chevalier says. "What ends up happening is you bump into someone you know or someone who is from the same talent you are originally — all you have to do is immerse yourself in the environment."

"The opportunities are out there, but it is incumbent upon in those who want it to put themselves in a position to meet people who are in the environments that are going to help facilitate whatever your objectives are," he continues.

Hamilton explained her experience raising money as a Black woman — investors didn't want to bet on her. It's a chicken and an egg situation, she says, and support for diverse founders in terms of programming and investors focused specifically on underserved communities are going to help break the cycle. It's not about charity, but equitable opportunities.

"I don't want any charity – I don't want an overabundance of kindness. Scaffold me like you scaffolded Mark Zuckerberg," Hamilton says, giving Facebook as an example of a company that was supported in a way she never had. "If you are going to be in a nascent ecosystem, you need to have structures that explain why your pitch deck has to be efficient, why you need a team. We've got to not focus just on the money piece, but on this whole psychosocial aspect."

With Hamilton's call to Houston's development as an equitable tech ecosystem, the conversation turned to discuss whether or not Houston is ready to provide this support to startups and rise to being the global innovation hub the city wants to be.

"We've got to find our tribe. We have all the pieces," Martinez says. "It's going to take time, and we have to be very intentional. ... It's really about thinking of Houston as a startup itself. How do we act as a team, and bring in partners and investors to make it a thriving ecosystem over time."

It takes commitment, Hamilton says, and that's happening in the Bayou City.

"Everything is not figured out right now — but there's a commitment to figuring it out," she says. "It's not going to be Silicon Valley overnight — it will never be Silicon Valley. Because this is Houston."

Everything you need to know about SXSW’s anticipated in-person return to Austin

know before you go

SXSW starts this week, and it’s the first in-person event since 2019, which had more than 400,000 people attend.

The Austin Convention Center will play host to SXSW EDU through Thursday, March 10; SXSW Film Fest runs from Friday, March 11-Saturday, March 19; SXSW Music Fest runs from Monday, March 14-Sunday, March 20, Interactive runs from Friday, March 11-Saturday, March 19, and Flatstock 77 runs from Thursday, March 17- Saturday, March 19. At the Palmer Events Center, the SXSW Wellness Expo will be held from Saturday, March 12-Sunday, March 13.

Click here for your guide to connecting with Houston innovators this year at SXSW.

If you’re one of the many people attending, here are some things you should know before you go.

First things first: COVID-19 protocols. Austin is now in Stage 2 of its COVID-19 risk-based guidelines, and SXSW has made the decision to keep its existing guidelines in place. That means anyone who is attending needs to provide proof of vaccination against COVID-19 or a negative COVID-19 test in order to pick up credentials.

Speaking of credentials, they can only be issued to, picked up by, and used by the participant named in the registration. All badge types can be picked up at Exhibit Hall 1 of the Austin Convention Center through March 19. For a list of the SXSW credential pickup dates and times, click here. Don’t forget to bring a government-issued photo ID and verification of vaccination or recent negative COVID-19 test.

As for getting around, you can catch a free ride on one of the circulating festival shuttles. You can also use pedicabs or public transit, or you can park close by and do some walking. Most of the venues are walkable and within a few minutes of the Austin Convention Center. For a look at road closures and commuting options, click here.

One way to help organize your time is by downloading the SXSW GO app. From the app, you can link your badge, RSVP for events, build your schedule, and sign up for notifications so you don’t miss those things you really want to see.

SXSW is a huge festival featuring events for many different genres, including music, film, television, gaming, and more. It will be difficult to attend everything you want.

Here’s some advice from Jim Kolmar, consulting film programmer for SXSW, and long-time attendee.

“I always tell people pick out three things you really want to do and make sure you do those,” he says. “Everything else, just have a plan, but leave it open to serendipity because your plan is going to fall apart at some point. There’s just no way to do everything exactly the way you want to. And I think that’s the best way to experience it, too. Just be in the moment.”

For those who don’t want to spend money but still want a SXSW experience, you can subscribe to free events here.

GHP introduces in-person Houston House for SXSW 2022

Q&A

Texas is just about two weeks away from SXSW's return to in-person activations and events since pre-pandemic times. The two-week conference includes conversations and activities within music, film, education, tech, and more. And this year, the Greater Houston Partnership is shining a spotlight on the Bayou City at the festival.

"With the return of the conference in person for the first time since 2019, we are thrilled to build on that momentum and host Houston House — a two-day activation featuring programming and networking opportunities for guests attending the conference," says Susan Davenport, chief economic development officer for the GHP.

Houston House, which first originated last year in digital form, will be held in Austin on Sunday, March 13, and Monday, March 14. Davenport shares more details on the activation in a Q&A with InnovationMap.

InnovationMap: Why did the Greater Houston Partnership decide to have a presence at SXSW this year?

Susan Davenport: As one of the premier tech conferences in the U.S., SXSW provides an incredible platform to promote Houston’s position as the most prominent emerging innovation hub in the country.

Houston was a featured partner at last year’s SXSW Online Conference, where the Partnership rallied innovative leaders from across the region for a series of virtual programming. With the return of the conference in person for the first time since 2019, we are thrilled to build on that momentum and host Houston House – a two-day activation featuring programming and networking opportunities for guests attending the conference.

With an expected attendance of 45,000 bright minds from around the globe, it’s the perfect venue to showcase Houston’s tech leadership and cultivate relationships that support the growth of our ecosystem.

IM: What can attendees expect from Houston House?

SD: This year’s activation will be held at the Line Hotel, an established SXSW venue in the heart of the action. Consistent with what attendees have come to expect from South by, Houston House will offer thought leadership programming featuring industry leaders and startup founders in a series of panel discussions on today’s most prominent topics in tech.

In addition to main stage programming, Houston House will also offer a lounge space that will serve as a landing pad for stakeholders and attendees to cultivate relationships. Each day of programming will conclude with a networking reception.

IM: The programming is geared around a few topics — what are some of these themes and how do they pertain to Houston innovation?

SD: On Sunday, March 13, our programming will be focus on topics like commercial aerospace, medical device innovation, cell therapy, and investment for diverse entrepreneurs. These panel sessions will showcase Houston’s leadership through the incredible work taking place at the Ion, Houston Spaceport, Johnson Space Center, and the Texas Medical Center.

On Monday, March 14, our programming will kick off the start of the SXSW Climate Change track and focus primarily on how Houston is leveraging its energy leadership to accelerate solutions for a low-carbon future. Topics will include VC investment in climate tech, corporate and startup partnerships, emerging low-carbon energy technologies, and ensuring an equitable energy transition.

Our full lineup of Houston House programming and speakers can be found online, along with an overview of the 2022 SXSW Conference.

IM: Who should stop by Houston House at SXSW?

SD: Anyone who is interested in technology, commercial aerospace, life sciences, and how DEI traverses with these industries will find value in our rockstar lineup of industry leaders, investors, and startup founders. We hope to see young professionals, entrepreneurs, investors, and executives.

For fellow Houstonians attending the conference, Houston House will serve as a home base to kick off your SXSW experience.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
