There were so many question marks at the beginning of the pandemic, especially for startup funding. Stephanie Campbell, who manages the most active angel network as well as a venture capital fund, says no one was sure how anything was going to pan out. Now, looking back on last year, VC did ok, she says on the Houston Innovators Podcast, and the Houston Angel Network saw membership growth.

"I think that given the markets with quite a bit of liquidity, people were looking for new and interesting ways to invest and make a return," Campbell says on the podcast. "In 2020, we actually grew by 30 percent and are up to 130 members of the Houston Angel Network and are continuing to grow through 2021."

When Larry Lawson started his career in the medical device industry, it was hard to get funding. The health tech founder and investor says if it wasn't oil or real estate, banks couldn't understand well enough to make a loan. So, he bootstrapped, raised from friends and family, and found venture capital support for his business endeavors over the years. Now, he's celebrating a $1.4 billion exit of his last business, Preventice Solutions, a deal that closed earlier this year.

The ecosystem in Houston has changed, he says, and he's seen it evolve as the Texas Medical Center grew and the Rice Business Plan Competition brought impressive student innovators from all around the globe.

"The health science community here in Houston is now known all over the world," he tells InnovationMap. "It's gonna just continue to grow and develop, and I hope to be a part of continue to be a part of it." Click here to read more.

For the first time, NASA has a Black woman at the helm of a space center. Vanessa Wyche has been named director of Johnson Space Center in Houston after serving as acting director since May 3.

"Vanessa is a tenacious leader who has broken down barriers throughout her career," Pam Melroy, deputy administrator of NASA, says in a news release. "Vanessa's more than three decades at NASA and program experience in almost all of the human spaceflight programs at Johnson is an incredible asset to the agency. In the years to come, I'm confident that Houston will continue to lead the way in human spaceflight."

As director of Johnson Space Center, Wyche now leads more than 10,000 NASA employees and contractors. Click here to read more.

The SEC expanded its definition of accredited investors, so now is the time for potential venture capitalists and angels to step up. Pexels

Here's what the new SEC accredited investor definition means for potential Houston VCs

guest column

This month. the Security and Exchange Commission, or SEC, modified the definition of "accredited investor," with the effect of dramatically increasing the number of people eligible to participate in non-publicly traded investments.

The SEC definition of accredited investor establishes requirements for who may invest in private deals, startups, and private funds. These rules are meant to protect individuals from investing in assets that are high risk and have little publicly accessible information.

Historically, accredited investor status was limited to those that met certain wealth or income thresholds — specifically, a net worth of $1 million excluding primary residence, or $200,000 in annual income for an individual or $300,000 combined annual income for married couples. The SEC's thinking was that higher net worth individuals or higher earners likely have the sophistication to evaluate the risks and the ability to financially withstand potentially losing money they invested in a private investment.

However, with fewer companies going public and an increased interest in participating in private deals, startups, and funds many have suggested the accredited investor rule appeared more and more antiquated.

The SEC's new definition adds individuals with certain professional certifications (Series 7, Series 65, or Series 82 license) and "knowledgeable employees" at private funds, regardless of an individual's level of wealth or income.

Now, individuals with heavy involvement in and responsibility for investment activities and those with financial certifications are assumed to have the financial sophistication and ability to assess the risks of private investments. The SEC also added the clients and employees of family offices, which are investment arms of high net worth families. In addition, the SEC also expanded the married couples' income calculation to include "spousal equivalent" to capture non-married couples.

It remains to be seen whether these additions to the definition of accredited investors will add a significant number of new angel investors, as many of the individuals with such certifications already meet the previous net worth or income requirements. The startup ecosystem, however, has welcomed the move away from wealth and income criteria, as a good first step toward opening the private offering markets to more qualified individuals.

If you now find yourself meeting any of these qualifications of accredited investor, what now? The Houston Angel Network is a great resource to help you navigate these new waters, by providing a framework and network to learn how to evaluate investment opportunities. A common rule of thumb is that nine out of ten startups fail and will return zero dollars to investors. It is prudent to invest in several startups or through a fund with experienced and capable managers to get the needed diversification to expect a return on your investment in this asset class.

Angel networks throughout the country exist to educate accredited investors and provide a network of sophisticated and experienced individuals across industries to support due diligence. By working together and learning from experienced investors, newly accredited investors can avoid common investment mistakes and can develop skills to evaluate non-public investment opportunities.

The upshot of the expansion of accredited investors is that the SEC still expects such investors to be sophisticated and well educated about investment opportunities with high risks and rewards. Investors new to non-public markets should consider joining a network like the Houston Angel Network, where they can see hundreds of startups a year and learn from experienced investors.

Additionally, new accredited investors can engage in the local startup community by volunteering their services as a mentor at a local startup development organization like the Ion, Rice Alliance, Capital Factory, Mass Challenge, Plug and Play and many more. If you are considering investing in startups or a fund, please reach out to us at the Houston Angel Network for more ways to get involved and learn.

Houston Angel Network sees membership growth amid pandemic

investing in investors

While the COVID-19 pandemic caused some investors to hit pause on some deals, the Houston Angel Network, which has doubled its membership over the past couple years, has maintained its deal flow and investment, while taking every opportunity to connect members virtually.

"Nothing's really changed — in terms of our activity — other than the fact that we can't meet in person," says Stephanie Campbell, managing director of HAN. "We quickly pivoted to virtual."

Campbell — who also is also a founding partner at Houston-based, female-focused venture capital group, The Artemis Fund — says she still saw the interest and need on each side of venture deals.

"What I realized was, especially working at a venture fund, the deal flow isn't going away. Companies still need capital — and investors are still interested in looking at deals," Campbell tells InnovationMap.

HAN, which was founded as a nonprofit in 2001, continues to be touted as among the most active angel network in the country. The organization has five industry groups that it focuses its deals on — energy, life sciences, technology, consumer products, and aerospace.

At each monthly meeting, members hear three pitches. However, Campbell is vetting many more companies far more deals and passing them along the network as she goes. All in all, HAN investors do around 100 deals a year with an average investment of $100,000.

Since Campbell joined in 2018, membership has doubled from 60 members to 120. Campbell says it's her goal to get to 150 members by the end of the year.

Stephanie Campbell has led HAN as managing director since 2018.

"Despite COVID, we've continued to grow," Campbell says, adding that she's heard investors express that they have more time now to dive in. "People are very much still interested in learning about deploying their capital into early-stage venture. They're looking for a network of like-minded individuals."

Campbell explains that, with the switch to virtual pitches and events, HAN is congregating more than ever. In the spring, Campbell introduced a thought leadership series, called Venture Vs. The Virus, that brought investment leaders together to discuss how the pandemic was affecting venture capital.

HAN is also using this time to better tap into technology to connect members with startups. On the back end, Campbell says, she's looking to enhance digital engagement with members and also improve data reporting within the organization.

From increasing networking and educational events and growing membership, HAN is prioritizing growing its place in the Houston innovation ecosystem. Campbell says she sees the pandemic is causing investors and tech talent on the coasts to re-evaluate where their living, and that's going to benefit Texas. Houston is going to see an influx of tech talent coming to town, and that's going to translate to more startups being founded locally.

"We want to make sure that we are a big part of this transition toward a more diverse and resilient economy," Campbell says. "Now's the time to lean in on Houston."

Houston brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.
