In a world where Amazon dominated the e-commerce world, Cart.com is offering merchants but an alternative and a supplemental tool.

As Remington Tonar, chief commercial officer of Cart.com, explains on the most recent episode of the Houston Innovators Podcast, Cart.com connects the dots for e-commerce companies, and, in fact, works alongside Amazon, too. While Cart.com clients can use the suite of software services to create their own shop, ship out of Cart.com's distribution centers, etc., they can also list their products on Amazon too.

"I like to view Amazon as co-op-etition. We can coexist with Amazon," Tonar says on the show. "We're not antithetical to Amazon. We're not mutually exclusive. We can work with folks who are selling on Amazon to build their direct-to-consumer business, and we are doing that today." Click here to read more and stream the episode.

In his new role, he will work with the Houston early-stage investing and startup community, including founders, early-stage startups, scaled startups, early-stage angel investors, venture capital investors, and corporate partners, to grow the Ion's presence in Houston.

"Houston and Texas are seeing unprecedented growth in tech and innovation. I am excited for the opportunity to continue building and supporting the Houston innovation ecosystem," says Sanchez the release. "An ecosystem needs harmony among all aspects involved, and I have always enjoyed connecting people. The overarching goal remains to build a vibrant ecosystem that supports a high frequency of connections between critical stakeholders to realize outsized success." Click here to read more.

What are RECs and what difference do they make? P.J. Popovic, CEO of Houston-based Rhythm, shares his expertise on Renewable Energy Certificates in a guest column for InnovationMap.

"Through PPAs, various risks, credit needs, and long-term commitments create challenges for many organizations to meet their sustainability goals. So, while RECs do not provide as material of a market signal as PPAs, with the recent changes in market prices, RECs can now be considered a meaningful, profitable market signal for renewable projects."

Houston expert: Why higher REC prices are good for the future of renewables

guest column

We all know what renewable energy is — wind, solar, biomass, geothermal, hydropower — but how do you purchase it? It's invisible. Not to mention when energy from any source enters the electricity grid, there's no way to track all those electrons.

Renewable Energy Certificates have made it possible

Renewable Energy Certificates, or RECs, allow us to track your clean energy. Each individual REC represents one megawatt-hour of clean energy generated. And while a REC isn't technically electricity, it represents the clean energy going into the electricity grid—meaning homes and businesses claim their commitment to renewable energy if their electricity is supported by RECs.

It's also important to understand what a renewable energy certificate is not: an offset. An offset represents a metric ton of emissions avoided and a REC represents 1 MWh of clean energy generated. While each have similar goals, they are not quite the same thing.

Not all RECs are created equally

The market for RECs is fluid. Due to the growth of the renewable energy market, RECs have been oversupplied for years. This has created low prices and little-to-no financial advantage for the facilities that generate clean electricity (e.g., wind facilities, solar farms, hydro plants).

In Texas, the retail electricity market is inundated with renewable electricity claims said to be supported by RECs. The energy plan you sign up for might come from solar, wind, biomass, or even trash incineration, but the renewable energy facilities likely are coming from outside Texas, located in places like California, Canada, or elsewhere. While there's no wrong way to switch to renewable energy, supporting renewable energy sources inside Texas helps Texans move closer to being a more sustainable state.

Choosing Texas renewable energy plans and your actions do have a true, real-world impact more than ever before

Some critics have argued that REC-supported renewable energy plans don't meet the highest standard of sustainability arguing RECs are not foundational to the existence of renewable energy assets. In other words, they argue that RECs don't provide a material revenue source for renewable projects because they don't incentivize new developments of renewable facilities to be built.

When RECs were trading for less than a dollar, this was a valid argument. But that was then, and this is now.

In the last year alone, voluntary renewable energy certificate prices have skyrocketed and are now between $7 and $10 per MWh. This means RECs can now contribute up to 30 percent of a renewable facility's revenue. Naturally, this encourages more and more clean-energy facilities and clean-energy jobs to be created. A win-win.

What about Power Purchase Agreements?

A Power Purchase Agreement, or PPA, is a tad different than a REC. In a PPA, the developer of a renewable project (solar arrays at a solar farm, or turbines at a wind farm) can sell the actual energy it produces over a 10-to-20-year contract.

While the sale of this renewable energy still contributes to a larger portion of project revenues, the revenue mix has clearly shifted, and RECs cannot be considered an immaterial incentive anymore. Sure, PPAs are a stronger market signal for renewable project development, but only a couple of hundred organizations globally utilize PPAs. This makes them very challenging for businesses to access.

Through PPAs, various risks, credit needs, and long-term commitments create challenges for many organizations to meet their sustainability goals. So, while RECs do not provide as material of a market signal as PPAs, with the recent changes in market prices, RECs can now be considered a meaningful, profitable market signal for renewable projects.

Making the future of renewable energy in Texas even brighter.

Texas cashes in among 10 best U.S. state economies in 2026 report

State Economics

A new study gauging the success or decline in economic performance in every state has revealed Texas' economy remains stable in 2026 after it dropped out of the top five to No. 8 last year.

Texas boasts the No. 8 best state economy in the U.S. this year, according to WalletHub's annual "Best & Worst State Economies" report. The personal finance website's analysts ranked all 50 states and the District of Columbia across 28 relevant metrics to measure each state's economic activity and health status, and its "innovation potential."

Notably, Texas leads the nation for the most exports per capita in the U.S. in a five-way tie with Louisiana, Kentucky, North Dakota, and Indiana. Across the study's three main categories, Texas ranked highly for its economic activity (No. 7) and economic health (No. 11), and the state's "innovation potential" rank is the 24th best in the nation.

This is how WalletHub ranked Texas' economic performance, where No. 1 is considered the best and No. 25 is considered average:
  • No. 6 – Change in non-farm payrolls
  • No. 8 – Change in GDP
  • No. 8 – Startup activity
  • No. 11 – Annual median household income
  • No. 18 – Government surplus/deficit per capita
  • No. 21 – Percentage of jobs in high-tech industries
  • No. 30 – Unemployment rate
WalletHub previously ranked Texas one of the top three states to start a business in 2026, with Houston earning its own entrepreneurial acclaim in separate rankings of the best big cities for new businesses and for starting a career.

"U.S. economic growth depends heavily on the performance of individual states, and some contribute more than others," the report's author wrote. "For example, California, Texas, New York and Florida have economies so large that if they were countries, they would rank in the top 20 in the world."

The five states with the worst state economies in 2026 are Rhode Island (No. 47), Maine (No. 48), Louisana (No. 49), Kentucky (No. 50), and West Virginia (No. 51).

The top 10 best state economies for 2026 are:

  • No. 1 – Massachusetts
  • No. 2 – Washington
  • No. 3 – Utah
  • No. 4 – California
  • No. 5 – Delaware
  • No. 6 – North Carolina
  • No. 7 – New York
  • No. 8 – Texas
  • No. 9 – Colorado
  • No. 10 – Florida

Houston lab explores how AI bots can help the elderly

AI for aging

The University of Houston’s Empathetic Lifespan AI & Robotics for Aging (ELARA) Lab is currently conducting research into how AI bots may be able to help the elderly live more social and independent lives through several ongoing initiatives.

The lab officially launched last month as part of the Gerald D. Hines College of Architecture & Design under the leadership of Assistant Professor Chorong Park. Part of the lab’s mission is tackling ongoing problems with aging, such as dealing with disabilities and social isolation. Researchers’ current work is focused on designing a new AI companion bot specifically tailored to the needs of older people.

“We need to take all the needs of older adults seriously,” Park said in a news release. “They won't use the robot if they don't feel at ease or if they feel they are being constantly watched.”

The field testing of new AI bots in this population hopes to overcome several traditional obstacles in technology use among the elderly. A study by Park shows that many older people have a fear of overt surveillance when using advanced AI. There is also ageism to consider. Most new technologies are designed with younger and employed buyers in mind, not retirees who may need help remembering daily tasks or accessing important information.

“The more older adults are excluded from technology development, the worse those technology gaps will become,” Park said. “AI and the majority of technologies are created for younger people, so my research method integrates older adults directly into the design process.”

ELARA recently collaborated with the Mamie George Community Center in Richmond, Texas, to track seniors’ response to desktop AI bots like Emo and Cupboo. Researchers also had participants use air-dry modeling clay to create their ideal robotic companion.

While the eventual AI bot may be able to help the elderly feel less isolated and more supported, there are concerns to consider. A study published in the Asian Journal of Psychology charted the development of delusional thinking in a 72-year-old woman who became convinced the empathic-response bot was in love with her. The rise of “AI psychosis” has the potential to exacerbate mental health problems, particularly in socially isolated people, which a quarter of Americans over the age of 65 are.

ELARA’s research is focused on creating “pet-like” AI models with enhanced trust cues. If it can overcome the dangers of socially isolated people relying on AI for companionship, it could be a big step forward for independent aging.

SpaceX IPO set to be biggest ever and could make Elon Musk a trillionaire

IPO News

SpaceX says it plans to raise up to $75 billion when it goes public this month, setting the stage for the largest-ever stock market debut and putting Elon Musk on course to becoming the world's first trillionaire.

The company, formally known as Space Exploration Technologies Corp., said Wednesday it will sell 555.6 million shares at $135 a piece in an initial public offering. The estimated proceeds would easily top the $26 billion raised by oil giant Saudi Aramco in 2019. The offering would also give SpaceX a market value of $1.77 trillion. Only six companies in the S&P 500 are currently worth more, with Nvidia tops at $5.2 trillion.

Besides the size of the offering and the expected proceeds, SpaceX's amended prospectus updates details about how much control of the company Musk will have. As SpaceX's CEO, chief technical officer and chairman, Musk's voting power will come primarily through his ownership of 5.22 billion Class B shares, which give the holder 10 votes for every share held. According to the filing, Musk would have 82.4% of the voting power in the company.

Forbes currently values Musk's net worth at $826 billion and his stake in SpaceX at $542 billion. The estimated value of his SpaceX holdings was based on an overall value for the company of $1.25 trillion. Based on those numbers, a $1.77 trillion valuation for SpaceX would boost Musk's net worth by $223 billion, making him a trillionaire. However, much of Musk's worth is in stock that he has yet to cash in.

Even as it makes a bid for a blockbuster market debut, SpaceX is currently losing billions of dollars a year. The filing shows that the company lost $2.6 billion from operations last year on $18.7 billion in revenue, and the losses kept piling up at the start of this year, too.

Fantastical plans

Time will tell how SpaceX fares on the market. Musk's plans for the company are as fantastical as the money he hopes raise in the sale.

Colorful, even frightening in parts, the IPO document strikes a contrast with the typically dry, technical prose in IPO documents, detailing plans to use proceeds from the sale to help put men on the moon again and perhaps even Mars. In one section, it talks of a need to build "a permanent human colony" on the red planet with "at least one million inhabitants" as existential threats loom that could consign man to "the same fate as the dinosaurs."

Musk has almost equally ambitious plans for his other publicly traded company, Tesla. His goal is to transform the maker of electric vehicles into a producer of robotaxis and humanoid robots. Dan Ives of Wedbush Securities wrote in a research note that he expects Tesla and SpaceX to merge next year.

AI plays a key role

Key to the success of both companies — and any merged entity — is artificial intelligence. In its IPO filing, SpaceX says it sees potential revenue from AI of up to $26.5 trillion. But that depends on another lofty Musk ambition — putting data centers in space, which is not technologically possible at the moment.

Transforming his space company into a primarily AI-focused company will be a challenge for Musk, who started xAI in 2023 with 11 other co-founders who have all since left. Some were recruited away by rivals.

Its main AI product, the chatbot Grok, is "less impressive than anything that we see from any other major player in the space, whether that's OpenAI, or Anthropic, or (Google's) Gemini," said IDC analyst Arnal Dayaratna.

Dayaratna said that doesn't mean SpaceX doesn't have potential as a major AI player, thanks in part to its computing partnership with Anthropic and Musk's recent deal that gave SpaceX the rights to buy AI coding tool Cursor for $60 billion later this year. Folding in Cursor's capabilities would give SpaceX access to the coveted business customers now using Anthropic's Claude or OpenAI's ChatGPT.

SpaceX plans to use the net proceeds from the IPO to fund the expansion of infrastructure for its AI and rocket businesses, and to beef up the constellation of satellites that power Starlink Mobile, among other investments.

The company plans to list on the Nasdaq under the symbol "SPCX" and could begin trading as soon as the end of next week.

And SpaceX isn't the only colossal market debut investors are now bracing for. Earlier this week, Anthropic submitted a confidential filing with the U.S. Securities and Exchange Commission to officially start its own IPO clock.

OpenAI has not yet reported filing the initial SEC paperwork, but an IPO from the ChatGPT maker is widely expected.

"This listing represents the first major test for public markets after years of muted IPO activity with SpaceX paving the way for AI giants Anthropic and OpenAI to follow soon after," Ives wrote.
