Passion is usually the motivator for starting a business, and this week's innovators to know have an undeniable passion for what they are doing.

Marc Nathan is passionate about Texas startups — it's why he started and still maintains a comprehensive newsletter of Texas innovation news. Meanwhile, Maggie Segrich and Meredith Wheeler are passionate about bringing together a community of women with Sesh Coworking.

Here's more of what you need to learn about this week's innovators to know.

While he technically lives in Austin now, Marc Nathan is extremely proud of his Houston heritage. A third generation Houstonian, Nathan worked as an entrepreneur before getting involved with the Houston Technology Center. The University of Texas alum's current role at Egan Nelson — an Austin-based, startup-focused law firm, that brought him back to Austin a few years ago.

As much of a Houstonian at heart he is, Nathan is a major player in the entire Lone Star State's innovation world. He publishes a weekly newsletter, called Texas Squared, that he hopes can connect the dots between Texas's four innovation ecosystems — Dallas, Austin, San Antonio, and Houston, or DASH, as he likes to call them.

"I can tell you 10 years ago being an innovation person in Houston, I couldn't have told you anything about what was going on in Dallas or Austin," Nathan says on the most recent episode of the Houston Innovators Podcast. "Now, we're seeing a lot more collaboration among cities, and I think it's very important and useful."

Working from home can be extremely isolating, but Meredith Wheeler found the "bro culture" of coworking off putting. For years she craved a female-focused community, and now with her business partner, Maggie Segrich, she's created exactly that with Sesh Coworking.

"We come at the creation of this space and the running of this community from the female experience," Wheeler tells InnovationMap. "Most coworking spaces, when they are run only by men, it's natural that they are coming from their perspective and experience."

The coworking space in Montrose officially opened for business on Feb. 3. Sesh has memberships and day passes available for anyone who wants to cowork, but the space is designed from the female perspective.

"For me, starting Sesh is kind of like giving women that space and opportunity to let their guard down, and feel like they can be their actual selves," Segrich says.

Lifelong Houstonian weighs in on growth within the city's innovation ecosystem over the past 20 years

HOUSTON INNOVATORS PODCAST EPISODE 17

Houston's innovation ecosystem might not have a bigger advocate based in Austin than Marc Nathan. The third generation Houstonian is one of the few people to see the city go through its highs and lows as a developing innovation ecosystem over the past few decades.

While his full-time job is working in marketing for Egan Nelson, an Austin-based, startup-focused law firm, Nathan's greatest contribution to the Texas startup scene is his weekly newsletter, Texas Squared, that gathers up the Lone Star State's innovation and startup news.

Nathan also used to work at the Houston Technology Center years before it converted into Houston Exponential and focused specifically on helping startups raise money.

"Finding money was relatively difficult, and it's not any easier now," Nathan says on this week's episode of the Houston Innovators Podcast. He notes that organizations like the Houston Angel Network and local venture capital firms like Mercury Fund have made a huge difference.

A lot has changed within Houston, Nathan says. There's more startups, money, and press around Houston innovation. He's also seeing more collaboration between the Texas cities he calls DASH —Dallas, Austin, San Antonio, and Houston.

"I can tell you 10 years ago being an innovation person in Houston, I couldn't have told you anything about what was going on in Dallas or Austin," Nathan says on the podcast. "Now, we're seeing a lot more collaboration among cities, and I think it's very important and useful."

Nathan discusses his experience in both Houston and Austin's startup scene, and where he sees this collaboration going. Plus, he weighs in on The Ion, the merge between Capital Factory and Station Houston, funding and accelerator trends, how to make the most out of SXSW and more.

From friends and family rounds to how to navigate a seed round, here's what you need to know about raising money in Texas. Getty Images

Here's what you need to know if you're raising a seed round in Texas

Guest column

In the vast majority of startups we've worked with across Texas, their "seed round" is not the first money in the door. That money is often called a "Friends & Family Round" and it's usually from people so close to the entrepreneurs that they are willing to take a gamble before there is really even much "there" to invest in. It also might include bootstrap funds put in by the entrepreneurs themselves.

After an F&F Round, Texas startups will pursue a "seed round," which generally includes some angel investors in the local and broader ecosystem. A problem we occasionally run into is that Texas entrepreneurs, including those in Houston, will get bad advice on what the right structures are for this kind of deal; either because they are reading a blog post from Silicon Valley (where things work VERY differently) or they're talking to someone marketing themselves as an "adviser" when their advice doesn't have much substantive deal experience backing it.

If your seed round is under $1 million, you will most likely structure it as a convertible note with a valuation cap and a 2 to 3 year maturity. Convertible notes are extremely slimmed down investment instruments that angel investors across Texas will be very familiar with. Usually, the "deal" in a convertible note round is that investors will get minimal up-front rights, in order to streamline early decision-making and keep legal costs down for negotiation, but they will get back-end protections like debt treatment if the company goes south. They will also almost always get a valuation cap and/or a discount on the price that future VCs pay, as recognition for the extra risk the seed investors are taking relative to later investors.

Once seed rounds get above $1 million, a more robust equity (stock) based investment structure starts to make more sense. There are two types of equity rounds, broadly speaking: seed equity and full VC-style equity. The latter involves a large set of heavily negotiated documents with robust investor protections, and is the structure most often utilized for a Series A (after seed). The former (seed equity) is a slimmed down version of full VC docs designed to give investors some rights, but keep negotiation costs (including legal fees) within a range that's reasonable for the smaller amount of money being raised. Investors vary as to whether they will accept simpler seed equity docs, or require you to give them full VC-style protections.

Given the diversity of investor expectations and contexts you're likely to run into in structuring a seed round, and the very high-stakes (and permanent) implications of the contracts you're going to sign, it's extremely important that advisers you work with have specialized experience in these kinds of deals.

In the case of lawyers specifically, it's also extremely important that they not have conflicts of interest with the investors you are raising money from. We too often see clever investors nudge entrepreneurs toward utilizing the investor's preferred law firm. Anyone with an ounce of honesty and experience can see why that's a problem.

Make sure you understand the high-level concepts and structures that are within the norms of your startup ecosystem, and then work with experienced, trustworthy advisors to translate everything into a deal that makes sense for your company's unique context.

UTHealth Houston officially opens new tower in TMC's Helix Park

open for innovation

UTHealth Houston School of Public Health recently opened its new state-of-the-art tower in the Texas Medical Center’s Helix Park.

The 350,000-square-foot, 10-story campus at 1930 Old Spanish Trail was celebrated with an official ribbon-cutting ceremony on Oct. 28. The $229 million project will consolidate all UTHealth Houston School of Public Health operations into one facility. It will also connect students who are at the Austin, Brownsville, Dallas, El Paso and San Antonio campuses with peers and faculty through digital and distance learning.

Disciplines taught in the new tower will include epidemiology, genetics, nutrition, health policy, data science and health promotion, UTHealth shared when the building first broke ground in 2023.

Architects Kirksey Architecture and Smith Group designed the building, and Vaughn Construction served as general contractor. The facility features labs for studying human disease, classrooms and spaces to support interdisciplinary and community-based research, a broadcast studio and a teaching kitchen. A skybridge over Old Spanish Trail connects the new tower with a plaza that's shared with MD Anderson.

“This new facility reflects the kind of forward-looking investment that will serve Texans for generations,” Janiece Longoria, vice chairman of the UT System Board of Regents, said in a news release. “By creating an environment where talented people can learn, collaborate, and pursue new ideas, UTHealth Houston is building capacity to meet the challenges of tomorrow while strengthening its impact across our state.”

UTHealth says the system aims for the new campus to expand on collaborative research efforts and continue graduate education, as enrollment at the School of Public Health has increased by 27 percent over the last five years.

“This new building, with its state-of-the-art education technology and learning environment, will strengthen and advance the school’s mission to educate and train the next generation of experts who will advance scientific discovery, shape evidence-based health policy, and lead innovative solutions to the complex health challenges in communities throughout Texas and across the nation,” Kevin Morano, senior vice president, provost and chief academic officer of UTHealth Houston, added in a news release.

Attending the ceremony were Dr. Melina R. Kibbe, UTHealth Houston president and Alkek Williams Distinguished Chair; Eric Boerwinkle, dean, M. David Low Chair in Public Health and Kozmetsky Family Chair in Human Genetics at the School of Public Health; Texas State Representative Lauren Ashley Simmons, Texas House District 146; representatives of the offices of Senator John Cornyn and Harris County Commissioner Rodney Ellis; and Dr. Theresa Tran, director of the Houston Health Department.

"This building represents far more than a home for our school,” Boerwinkle added in the release. “It represents the people who make our mission possible: the faculty, staff, and students who fill each laboratory and classroom with curiosity, discovery, and purpose to improve the population’s quality of life.”

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.
