Just look at any smartphone on the market and it becomes evident just how pervasive mobile apps have become, especially social media apps.

As the social networking sphere has revolutionized communication, technology has spawned multitudinous variants in the most organic way. That kind of technological momentum lends itself to why platforms like Guide App have a chance to be the next big thing in the space.

The company's CEO and co-founder, Tim Salau, tells InnovationMap that Guide is a social learning and development platform that aims to revolutionize learning experiences for creators, leaders, and organizations.

“Guide is a social learning platform for creators who are freelancers and work in the entertainment and media industry,” says Salau, Houston native and University of Texas graduate. “And they can use Guide to create and learn production skills. We pivoted in late 2019 as the pandemic hit, and we realized that Guide could be used as a B2B platform and solution for businesses to onboard and train their remote workers.

“So that's really what makes us money, and we really decided to build it because we saw that there was a huge gap in the business space of a bite-sized training platform and solution, and to do what TikTok and Reels was doing in the consumer space, but for professionals with security and privacy in mind for organizations,” he says.

With the pivot, businesses can now use Guide as a platform to onboard and train new hires for their respective companies.

“Ideally, it would be pretty much anyone within the marketing department, the product management division, or even engineers within their organizations who are creators in the sense of migrating to creative work in their own different disciplines,” says Salau. “And they could use Guide to potentially maybe create a video that's 90 seconds or less on everything a new hire needs to know within the first 90 days in the product management role or in the marketing role.”

Tapping into trends

Salau explains how he's got his ear to the ground when it comes to trends within media.

“With the way that things are moving in the entertainment and media industry and what's been happening with these strikes, I see the short-form content becoming even more important because people are not necessarily attending movie theaters at a high engagement rate,” says Salau. “Then there are multiple streaming platforms have so many gates and paywalls up, a lot of people aren't necessarily using all of these streaming platforms and seeing all of the long-form content out."

“I'm starting to see that in the next three to five years, macro content will become more important, and instead of the streaming era that we've seen in the last few years or in the last decade or so led by Netflix, I'm going to use our mock theory, we're going to start seeing a beaming era in which we're going to start seeing content being pushed to creators and consumers, that is literally tailored to what they want.”

According to Salau, platforms such as Instagram and TikTok push content based on their respective algorithms that followers don’t necessarily want to see, and that takes time away from the content they need, when they need it.

“Looking forward, it’s clear that in the sense of taking away all of the distractions that we see on these platforms, at Guide, we want to push content as it comes from the creators,” says Salau. “And for us, that focus will be on microcontent, which is content that’s 90 seconds or less.”

Data shows that the best micro content is video content that clocks in around 15 seconds.

“Content that goes up to 30 seconds is probably even cutting it a little bit too long, but the content that really goes a lot, and goes really viral on those platforms is 15 seconds,” says Salau. “And now that TikTok is becoming a more long-form entertainment platform, you're starting to see them kind of strip away from what really got them popular and buzzworthy.”

Monitoring monetization

Popularity aside, one of the major tenets of content creation is monetization.

“Getting to the point where creators will be able to monetize their content is our goal at Guide,” says Salau. “We have to build up towards that goal, but that’s the intent. We intend on having them be able to create profiles where they can actually list their merch. They can post about merch in their videos, and more importantly, get to a point where people can actually buy the entertaining content that they have.”

Once Guide reaches monetization, creators will be able to list content at the price they want it and have associated merchandise of their brand. This is a huge difference from how TikTok and Instagram and other consumer video platforms get creators paid.

“We see that it's better to actually go the other route and actually allow creators to monetize their own brand, which is what every creator often really wants,” says Salau. “That’s ideal because when a creator brings consumer brands into the picture, they have to play to what they want from an advertisement and dollars type of standpoint. So, we don't want to actually get into that world. We want to really keep everything creator oriented.”

Curating a culture of creators

At this point, Guide has about 150 creators, because they’ve been very selective with their icon program.

“We don’t believe that everyone’s a creator,” says Salau. “Because if everyone is a creator, then no one is a creator.

“And we kind of see this with a lot of the creator platforms out there. Just because anyone can create content with a smartphone doesn't mean it's content that's edifying or beneficial that people are actually enriching and learning from. So, we're really big on learning, because we see ourselves in that space.”

As Salau and team look forward with Guide, they plan on continuing to address the learning and talent development gap for remote and mobile teams. They’ll also remain focused on being the kind of platform where creators can talk about the behind-the-scenes and the process of how to make music or how to approach acting, or how to think about set production when on a set.

“With Instagram and TikTok, it’s really much more about fun and virality, and doing something that gets a reaction, versus helping people learn,” says Salau. “So, with us, the feedback we've received is, ‘I get it,’ and ‘I'm interested.’ And I want to continue learning and growing with y'all. Thank you.”

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
