The amount of venture capital pumped into Houston-area companies shriveled in 2023, dropping to its lowest level since the pandemic year of 2020.

The latest PitchBook-NVCA Venture Monitor shows Houston-area businesses collected nearly $1.5 billion in venture capital in 2023, down from more than $2.2 billion in 2022 and over $2.6 billion in 2021. The amount of venture capital fell below $1 billion in both 2019 and 2020.

Houston-based Axiom Space accounted for the biggest chunk of the region’s VC haul in 2023 — a series C round worth $350 million. According to InnovationMap reporting, other local startups leading the way last year in VC were:

Here are Houston area’s full VC numbers for the past five years, according to the PitchBook-NVCA report:

  • 2023 — $1.478 billion
  • 2022 — $2.207 billion
  • 2021 — $2.625 billion
  • 2020 — $718.94 million
  • 2019 — $950.76 million

Across the country last year, $170.6 billion was invested in private companies, says the report — down $71.6 billion from 2022 and roughly half the sum invested in 2021.

In the report, Bobby Franklin, president and CEO of NVCA, notes that while the continued drop in U.S. venture capital activity “does not lend itself to optimism, it would be a mistake to declare the market in crisis. Rather, the market has changed. From interest rates to foreign conflict, the world looks very different than it did two years ago, and a new set of problems needs to be solved for.”

Greater Houston Partnership researcher identifies the city's top tech specialties

HOUSTON INNOVATORS PODCAST EPISODE 48

When you look at Houston's venture capital investment patterns, what do they tell you? To Josh Pherigo, research director of data analytics at the Greater Houston Partnership, it paints a picture of what tech and startup niches are thriving.

Based on PitchBook data, Pherigo put together an analysis of what industries within Houston are attracting the most investments. The study came out of the fact that Houston's hold on oil and gas is going to shift as the industry goes through the energy transition. Since O&G is such a crucial part of Houston's economy, the city will have to see a rise in new industries to remain competitive with its economy.

"The idea was to look at the innovation ecosystem and see what the technologies are that are doing well here at at attracting VC funding," Pherigo says on the Houston Innovators Podcast. "And by seeing how well certain technologies are doing, we'll be able to see if these are some areas that have some natural competitive advantages in Houston's economy that we can then use to spur growth in the next few decades — and even just out of the recession we're in right now."

The report found that life science and oil and gas currently attract the most VC investments in Houston, but Pherigo found potential in a few other industries like B2B payments technology — Houston-based fintech startup, HighRadius recently raised $125 million.

The study, which also compared Houston to Austin and Dallas, found that there was a cleantech war emerging between Austin and Houston. While Houston's ecosystem has a greater presence of cleantech startups, Austin cleantech is still bringing in more VC investments. However, in Houston, between new corporate incubators and Greentown Labs entering Houston, the city is creating a lot of infrastructure for this industry.

"It's going to be interesting over the next few years to see how Houston can position itself as the leader in Texas for this, because they are going to have a lot of competition from Austin," Pherigo says.

Pherigo goes into more detail about what he found interesting in the report, and even dives into what the data shows for the future of Houston's tech specialties in the episode of the podcast.

Report finds Houston venture capital firm has made the most Texas deals since 2010

At the top

When it comes to tracking venture capital deals coming out of Texas since 2010, a Houston fund tops the list — but just barely. Houston Angel Network edged out Austin-based Central Texas Angel Network by one deal.

The report by PitchBook counted deals from 2010 up to March 4 that were made with Texas companies. Ten VC funds were listed and, aside from HAN, Mercury Fund was the only other Houston VC. The other eight funds are located central Texas — with the exception of Right Side Capital Management, which has invested in 45 Texas companies since 2010.

"Texas is currently in a transition powered by high-tech investments that lie in contrast to the slow-paced cattle ranches spread throughout the rural areas of the country's 28th state," the report states. "Partly as a result of the relatively new tech scene, Texas was home to three of the 10 fastest-growing cities in the United States in 2018, according to Forbes."

According to the data, VC funding had been on a downward trend since 2013, when the state raked in $2.83 billion in 536 deals. However, 2018 marked a turn for the state with $3.11 billion in 461 deals — a smaller deal count compared to 2013.

Despite this VC deal growth, compared to the rest of the country, Texas ranks fourth when it comes to VC investment market share. California holds over 52 percent of the market, New York has over 10 percent, and Massachusetts has almost 10 percent itself, per PitchBook data. Meanwhile, Texas reportedly holds only 3.43 percent of the market.

PitchBook also identified the top 10 VC deals investing in Texas companies closed since the beginning of 2018 — none of which were into Houston companies. The list's top three had nine-figure investments — Austin-based Bungalo with a $250 million Series A, Dallas-based Peloton Therapeutics with a $150 million Series E, and Richardson, Texas-based Hedera Hashgraph with a $101 million Seed round.

Growing Houston startup moves into 43,000-square-foot facility amid 'hypergrowth phase'

major milestone

A Houston startup has moved into a new space that's more than four times larger than its previous setup — a move that's setting the company up to scale its business.

NanoTech Materials celebrated its move into a new facility — a 43,000-square-foot space in Katy, Texas, this week. The materials science company currently distributes a roof coating that features its novel heat-control technology across the company. Originally founded in a garage, the company has now moved from its 10,000-square-foot space at Halliburton Labs into the larger location to support its growth.

“The new facility allows us to not just focus on the roofing, and that’s growing at a pretty rapid pace, but also stand up different production lines for our next iteration of technologies coming-out," Mike Francis, co-founder and CEO of NanoTech tells InnovationMap.

The space allows for a 340 percent increase in the manufacturing and operational capabilities, including producing 55 million square feet a year of roof coating. Francis says the new products he's focused on launching and scaling include a wildfire protectant coating and liquid applied insulation for trucks and containers to control heat for driver and worker safety.

Francis adds that he will be expanding the company's team to support this growth.

“We’re constantly hiring now,” he says. “We have about 25 employees right now. Next year, we’ll probably be double that. We’re kind of in a hypergrowth phase."

Francis likes to credit Houston in part for NanoTech's ability to grow at this pace and to be successful.

“Houston has a shot at being one of the top startup cities of the world — I think it’s going to take a lot of time and capital, but what makes Houston different is its ability to scale existing technologies,” Francis says.

“I really think that Houston is already the spot to take an existing technology and build a team around it to turn it into a company because you have all of the players — whether it’s the end customer or the incubators and 'scalerators' — and you have all of these pieces coming into place," he continues. "Maybe it’s not the best place to start a company, but it’s definitely the best place to scale a company because of the ecosystem is really willing to participate and raise up startups like ours."

As the first company selected for Halliburton's incubator, Halliburton Labs, when it launched in 2020, NanoTech has worked closely with the company that housed and supported them for years.

“Once you’re in the Halliburton Labs fold, they are always just a phone call away from making something happen," he says. “We’re transferring all that knowledge into a bigger facility — growing up and graduating from what they gave us.”

Last year, NanoTech raised an oversubscribed funding round that brought on a handful of new investors. The details of the round were not disclosed, but NanoTech did release that the round included participation from three institutional investors, two corporate-strategic investors, and seven family offices. The company originally raised its seed round in 2020.

The NanoTech team, including Francis and Carrie Horazeck, chief commercial officer, joined the Houston Innovators Podcast last year to discuss how they've rolled out their first line of business.


Texas lands in top 10 most-expensive cities for running a new business

pay up

Everything is bigger in Texas — or at least somewhat bigger — and that appears to include the cost of running a new business.

A new ranking from business consulting firm Venture Smarterputs Texas at No. 9 among the states with the highest expenses for starting and operating a business.

New York appears at No. 1 on the list, followed by Washington and Massachusetts.

The cheapest state? Mississippi. It was preceded in the ranking by Kentucky and North Dakota.

To come up with its list, Venture Smarter looked at eight metrics, including corporate tax rate, average LLC filing fees, average real estate costs, and minimum wage.

Texas scored 59.74 out of 100 for startup expenses, with a higher score being worse.

The Lone Star State tied with Tennessee for the highest initial LLC filing fees ($300). But unlike many other states, Texas doesn’t require business owners to pay LLC filing fees each year to keep a business incorporated.

Texas fared well on several counts, though, such as no corporate tax, a low state-mandated minimum wage ($7.25 an hour), and relatively low real estate costs.

“This research aims to provide valuable insights into the business climate across various states, offering new entrepreneurs the information they need to make well-informed decisions on their entrepreneurial journey,” Venture Smarter says in a statement. “By understanding the unique characteristics and challenges of each state, aspiring business owners can navigate the complexities of different markets and optimize their chances of success.”

How to evaluate an IPO, according to Houston researchers

houston voices

Many investors assume they can judge the strength of an IPO based on the reputation of the underwriter supporting it.

However, a recent study by Rice Business professors Anthea Zhang and Haiyang Li, along with Jin Chen (Nottingham University) and Jing Jin (University of International Business and Economics), proves this is only sometimes true — depending on how mature the stock exchange is.

Getting your company listed on the stock market is a big step. It opens new opportunities to raise money and grow the business. But it also means facing increased regulations, reporting requirements and public scrutiny.

To successfully launch an initial public offering (IPO), most companies hire “underwriters” — financial services firms — to guide them through the complex process. Because underwriters have expertise in valuations, filing paperwork and promoting to investors, they play a crucial role in ushering companies onto the market.

In well-established markets like the New York Stock Exchange (NYSE), an underwriter’s reputation carries immense weight with investors. Top-tier banks like Goldman Sachs have built their reputations by rigorously vetting and partnering with only the most promising companies. When Goldman Sachs takes on the role of underwriter, it sends a strong signal to potential investors that the IPO has met stringent standards. After all, a firm of Goldman’s caliber would not risk tarnishing its hard-earned reputation by associating with subpar companies.

Conversely, IPO firms recognize the value of having a prestigious underwriter. Such an association lends credibility and prestige, enhancing the company’s appeal. In a mature market environment, the underwriter’s reputation correlates to the IPO’s potential, benefiting both the investors who seek opportunities and the companies wanting to make a strong public debut.

However, assumptions about an underwriter’s reputation only hold true if the stock exchange is mature. In emerging or less developed markets, the reputation of an underwriter has no bearing on the quality or potential of the IPO it pairs with.

In an emerging market, the study finds, investors should pay attention to how much the underwriter charges a given IPO for their services. The higher the fee, the riskier it would be to invest in the IPO firm.

To arrive at their findings, the researchers leveraged a unique opportunity in China’s ChiNext Exchange. When ChiNext opened in 2009, regulations were low. Banks faced little consequence for underwriting a substandard IPO. Numerous IPOs on ChiNext were discovered to have engaged in accounting malpractice and inaccurate reporting, resulting in financial losses for investors and eroding confidence in the capital markets. So, for 18 months during 2012-2013, ChiNext closed. When it reopened, exchange reforms were stricter. And suddenly, underwriter reputation became a more reliable marker of IPO quality.

“Our research shows how priorities evolve as markets mature,” Zhang says. “In a new or developing exchange without established regulations, underwriter fees paid by IPO firms dictate the underwriter-company partnership. But as markets reform and mature, reputation and quality become the driving factors.”

The study makes a critical intervention in the understanding of market mechanisms. The findings matter for companies, investors and regulators across societies, highlighting how incentives shift, markets evolve and economic systems work.

The research opens the door to other areas of inquiry. For example, future studies could track relationships between underwriters and companies to reveal the long-term impacts of reputation, fees and rule changes. Research along these lines could help identify best practices benefiting all market participants.

“In the future, researchers could explore how cultural norms, regulations and investor behaviors influence IPO success,” says Li. “Long-term studies on specific underwriter-firm pairs could reveal insights into investor confidence and market stability. Understanding these dynamics can benefit companies, investors and policymakers alike.”
