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.

Houston professor awarded $2.6M grant for retina, neurological research

seeing green

University of Houston College of Optometry Professor John O’Brien has received a $2.6 million grant from the National Eye Institute to continue his research on the retina and neurological functions.

O’Brien is considered a leading expert in retinal neuroscience with more than 20 years of research in the field. The new funding will allow O’Brien and his team to continue to study the dense assembly of proteins associated with electrical synapses, or gap junctions, in the retina.

Gap junctions transfer electrical signals between neurons. And the plasticity of gap junctions changes the strength of a synapse, in turn changing how visual information is processed. Previous research has shown that reduced functions of electrical synapses could be linked to autism, while their hyperfunction may lead to seizures.

“The research we propose will significantly advance our understanding of the molecular complexes that control the function of electrical synapses,” O’Brien said in a news release.

The team at UH will work to identify the proteins and examine how they impact electrical synapses. It is particularly interested in the Connexin 36, or Cx36, protein. According to O’Brien, phosphorylation of Cx36, a short-term chemical modification of the protein, serves as a key driver of plasticity. And the protein has been linked to refractive error development, which is one of the largest vision problems in the world today.

Additionally, OBrien’s research has shown that plasticity is essential for all-day vision, allowing the retina to adjust sensitivity and sharpen images. He has also built a catalog of the core set of proteins surrounding electrical synapses that are conserved across species. His research has been funded by the NEI since 2000.

Capwell Services

Houston-based methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the US and Canada, equivalent to more than 400 million metric tons of CO2e per year. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

Deep Anchor Solutions

Offshore energy consulting and design company Deep Anchor Solutions aims to help expedite the adoption of floating offshore energy infrastructure with its deeply embedded ring anchor (DERA) technology. According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has not raised VC funding, but has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTechNexus LiftOff and others. Lee is an Activate 2025 fellow.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers and rubbers. The company reports that it plans to open its first commercial plant in the next 18 months.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch and lead engineer Trey Sheridan, the company has raised just under $1 million in capital and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch and other organizations.

Torres Orbital Mining (TOM)

Space tech company Torres Orbital Mining aims to pioneer the sustainable extraction and processing of lunar regolith and designs and builds robotic systems for excavating, classifying, and delivering lunar material. The company aims to accelerate a permanent and ethical human presence on the Moon.

The company was founded this year by Luis Torres, a current MBA candidate at Rice Business.

Wellysis USA Inc.

Wellysis USA Inc. works to detect heart rhythm disorders with its continuous ECG/EKG monitor with AI reporting. Its S-Patch cardiac monitor is designed for extended testing periods of up to 14 days on a single battery charge. The device weighs only 9 grams, is waterproof and designed to be comfortable to wear, and is considered to have a high detection rate for arrhythmias. It is ideally suited for patient-centric clinical trials to help physicians make diagnoses faster, cheaper and more conveniently.

It was established in Houston in 2023 and participated in the JLABS SFF Program the same year. It closed a $12 million series B last year. It was founded by CEO Young Juhn, CTO Rick Kim, CFO JungSoo Kim and chief strategy officer JoongWoo Kim.

The Ion taps John Reale for startup and investor role

new hire

The Ion has named John "JR" Reale as its director for startups and investor engagement.

In his new role, Reale, a longtime leader in Houston’s startup ecosystem, will work to strengthen the innovation district's founder and investor network.

"Here’s what I’ve come to believe: the Ion is not just a building, not just a real estate play, and not just another innovation district. COVID, remote work, and shifting market dynamics changed the rules. Key ingredients like co-working, events, and community, while impactful, are no longer enough on their own," Reale shared on a LinkedIn post announcing the move. "What’s needed are advantages ... We need to intentionally design a system that repeatedly delivers advantages so founders can pull forward their visions."

Reale previously served as executive in residence and venture partner at TMC Venture Fund and co-founded Station Houston. He also serves as managing director of Integr8d Capital. He's an investor and serves on the board of directors for a number of venture-backed companies, including Cart.com, Lionguard and others.

The Ion will host "Today Is Day One – A conversation with John (JR) Reale" to welcome Reale to the role on Tuesday, Oct. 21. Reale will be joined at the event by Heath Butler, partner at Mercury, to discuss their thoughts on shaping Houston's founders ecosystem, as well as the Ion’s Founder Advantage Platform.

"On top of this connected architecture, we will build product. That product will be the Founder Advantage Platform to remove friction, compress time, and compound outcomes," Reale continued on LinkedIn. "This is the system that will drive repeatable experiences, and naturally, make these journeys so much more fun."
