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.

plugging in

Leading innovation platform Plug and Play announced the opening of its new flagship Houston-area location in Sugar Land, which is its fourth location in Texas.

Plug and Play has accelerated over 2,700 startups globally last year with corporate partners that include Dell Technologies, Daikin, Microsoft, LG Chem, Shell, and Mercedes. The company’s portfolio includes PayPal, Dropbox, LendingClub, and Course Hero, with 8 percent of the portfolio valued at over $100 million.

The deal, which facilitated by the Sugar Land Office of Economic Development and Tourism, will bring a new office for the organization to Sugar Land Town Square with leasing and hiring between December and January. The official launch is slated for the first quarter of 2025, and will feature 15 startups announced on Selection Day.

"By expanding to Sugar Land, we’re creating a space where startups can access resources, build partnerships, and scale rapidly,” VP Growth Strategy at Plug and Play Sherif Saadawi says in a news release. “This location will help fuel Texas' innovation ecosystem, providing entrepreneurs with the tools and networks they need to drive real-world impact and contribute to the state’s technological and economic growth."

Plug and Play plans to hire four full-time equivalent employees and accelerate two startup batches per year. The focus will be on “smart cities,” which include energy, health, transportation, and mobility sectors. One Sugar Land City representative will serve as a board member.

“We are excited to welcome Plug and Play to Sugar Land,” Mayor of Sugar Land Joe Zimmerma adds. “This investment will help us connect with corporate contacts and experts in startups and businesses that would take us many years to reach on our own. It allows us to create a presence, attract investments and jobs to the city, and hopefully become a base of operations for some of these high-growth companies.”

The organization originally entered the Houston market in 2019 and now has locations in Bryan/College Station, Frisco, and Cedar Park in Texas.
