4 Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes a podcast with a tech founder supporting small businesses, a mom designing next-generation bibs, and two energy tech collaborators.

For decades, small businesses have operated in essentially the same manner — handwritten notes to request time off, manual punch cards to clock in, and verbal agreements to swap shifts. And 10 years ago, Houstonian Rushi Patel thought it was time to upgrade these local shops, eateries, and other businesses.

Homebase, which was founded in San Francisco in 2014 and has its largest office in Houston, provides a suite of software tools for employee scheduling, time tracking, communication, and task management for its users, most of which are small businesses.

After a decade of growing its technology and clientbase, Patel, co-founder and COO of the company, explains the unique challenges these small businesses face on the Houston Innovators Podcast — as well as how Homebase helps.

"It's a bit of an orchestra in terms of what entrepreneurs have to do. Your job is to compose a little, but conduct as well," Patel says on the show. "You've built the song of what you want to have happen, but you're conducting lots of different things to make it a reality as a small business owner." Read more.

Ashley Gooch has taken her entrepreneurial spirit from the fitness studio to the finger foods.

The Houston-based founder of high-end cycling studio RYDE and mom of three has launched a new baby gear brand, Babynetic. The company debuted its first product this month: the Babynetic bib.

Using a patented magnetic closure, the colorful platinum-grade silicone bibs are designed to snap and stay secured while holding up to four pounds of food. The snap is intended to be easy for parents to use, but more difficult for messy little hands to remove without assistance.

“As busy moms ourselves juggling careers and with five kids between us, we needed baby gear we could rely on,” Gooch said in a statement.Read more.

Houston tech founder shines spotlight on small businesses with new awards initiative

houston innovators podcast episode 234

For decades, small businesses have operated in essentially the same manner — handwritten notes to request time off, manual punch cards to clock in, and verbal agreements to swap shifts. And 10 years ago, Houstonian Rushi Patel thought it was time to upgrade these local shops, eateries, and other businesses.

Homebase, which was founded in San Francisco in 2014 and has its largest office in Houston, provides a suite of software tools for employee scheduling, time tracking, communication, and task management for its users, most of which are small businesses.

After a decade of growing its technology and clientbase, Patel, co-founder and COO of the company, explains the unique challenges these small businesses face on the Houston Innovators Podcast — as well as how Homebase helps.

"It's a bit of an orchestra in terms of what entrepreneurs have to do. Your job is to compose a little, but conduct as well," Patel says on the show. "You've built the song of what you want to have happen, but you're conducting lots of different things to make it a reality as a small business owner."



Patel explains how optimizing these personnel aspects of the business frees up founders and managers and improves the employee experience too. Currently, the job market is competitive for these types of businesses, and retention and hiring are major focus points for entrepreneurs.

With 10 years of data and experience of working with small businesses, Homebase introduced a new awards program this week in honor of National Small Business Week. The inaugural Top Local Workplace Awards honored over 50,000 businesses across the country for a range of positive workplace factors — like pay transparency and employee engagement.

"There are over 2 million employee-centric, main street type of businesses in the United States," Patel says, "these are the restaurants, the retailers, and the service providers. They employ north of 70 million people, so there's a lot of impact that these businesses can have. But what we found was they deserve recognition, and there wasn't recognition for the good practices that these employers were doing."

Using its data, which includes over 2.5 million hourly worker data points, Homebase's team implemented the awards to highlight the companies providing their employees — who are in most cases considered a work family, as Patel says — with a great experience.

Here's the income it takes to live comfortably in Houston in 2026

Money Talk

2026 report analyzing how much it costs to live "in sustainable comfort" in the biggest U.S. cities has found Houston residents have the 11th lowest salary requirement to live a comfortable life in 2026.

SmartAsset's annual report found single adult residents in Houston need to make $89,981 a year to qualify as "financially stable." Compared to last year, single Houstonians needed to make $83 more to live comfortably in the city.

Families with two working parents and two children need to make a household income of $204,672 to have a financially stable life in Houston, the report found. That's almost $2,000 less than what families needed to make last year.

To determine the rankings, SmartAsset's analysts examined 100 of the largest U.S. cities and used the latest cost of living data – such as the costs for housing, food, transportation, and income taxes where applicable – from the MIT Living Wage Calculator for childless individuals and for two working adults with two children.

For the purpose of the study, the 50/30/20 budgeting strategy was used to determine "comfortable lifestyle" costs for both individuals and families: 50 percent of income to cover needs and living expenses, 30 percent for "wants," and 20 percent for savings or paying down debt.

Here's breakdown of a Houston resident's comfortable lifestyle based on SmartAsset's findings:

  • $44,991 dedicated to needs and living expenses
  • $26,994 dedicated to wants
  • $17,996 dedicated to savings or debt repayment

This is SmartAsset's interpretation of a comfortable lifestyle for families of four:

  • $102,336 dedicated to needs and living expenses
  • $61,402 dedicated to wants
  • $40,934 dedicated to savings or debt repayment
SmartAsset said single individuals and families should compare the fluctuating local cost of living and their long-term goals to fully "understand the context" of their respective household incomes. But it's worth pointing out that a financially stable life in Houston isn't quite attainable for many residents: The city had a median household income of $64,361 in 2024, according to the U.S. Census Bureau.

Comfortable salaries in other Texas cities

Elsewhere in Texas, the report found that families in the Dallas-Fort Worth suburbs Frisco and McKinney "are closest to a comfortable salary."

"In Frisco, the median household earns $145,444 – substantially higher than the national median of $83,730," the report's author wrote. "This figure also accounts for 63.1 percent of the $230,464 income a family of four in Frisco needs to live comfortably. In McKinney, TX, the $124,177 median household income accounts for 53.9 percent of the $230,464 needed."

Both cities also tied with Plano for the 29th highest salary needed nationally to live comfortably in 2026. Single adults living in these cities need to make $109,242 a year to live a financially stable life this year.


On the opposite end, San Antonio has the lowest salaries needed to live comfortably in the U.S. Single adults only need to make $83,242 a year, and $192,608 for families of four.

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.”
