There's an adage in investing that you should only invest in what you know. Generally speaking, this is a good rule — if you do not understand a company product or have no experience with its industry, then investing in a specific company could be risky. Yet, there are times when it's necessary to get out of your comfort zone and try something new and adventurous. The challenge is determining how to do that.

We are financial advisors from Houston and San Francisco, and we frequently do just that — encourage our clients to explore investments out of their comfort zones.

In Houston, we understand energy. As of 2017, Texas accounted for 37 percent of the nation's crude oil production and 24 percent of its natural gas production. And as of January 2018, Texan oil refineries accounted for 31 percent of the nation's refining capacity — and that is just oil. In 2017, Texas lead the country in wind-generated electricity and generated a quarter of all wind power in the US. It is safe to say, we feel comfortable talking the language and investing in the energy industry. Whether it is machinery fabrication for upstream, construction of pipes for midstream, or refining downstream, some Texans are comfortable investing in these areas.

In San Francisco, we understand tech, whether it involves social media, silicon, or apps. We have five of the top 10 most prominent tech companies in the world. In 2018, the technology industry accounted for around 62 percent of all office leasing activity in San Francisco. The Bay Area also dominates venture capital investment, accounting for 45 percent of all capital investment in the U.S, in large part because of tech startups in the area.

Naturally, we see that some investors in our hometowns feel comfortable investing extensively in these two industries. Sometimes, these investments take the form of venture capital, other times they are individual stocks.

For Houstonians, allocating all of their investments to the energy industry carries too much risk should the energy industry falter. The same is true for San Francisco with venture capital and technology.

Therefore, we encourage investors to diversify their portfolios by placing funds in multiple vehicles and equities with the knowledge that different industries will react differently to market ups and downs. While there is never a guarantee of the outcome, diversification is one of many factors critical to long-term investment success.

For Houstonians and San Franciscans, there are other industries we understand in which we can invest. For example, Houston boasts the largest medical center in the world with roughly 361,000 people employed in the healthcare industry. While San Francisco employs roughly 277,500 in tourism. If you're looking to diversify your portfolio, look around to see the opportunities in which other people are investing. You may be surprised about what you learn, and ultimately how comfortable you can become investing in industries you may be unfamiliar.

We do not recommend ever investing in a product or industry that you have no understanding of at all. However, if you have excitement about an investment opportunity and feel there is potential for growth to your portfolio, your investment may prove fruitful in the future. Still, please seek out a financial advisor to help.

Zach Ellis Jr., founder and general partner of South Loop Ventures, says the firm wants to address the "billion-dollar blind spot" of inequitable distribution of venture capital to underrepresented founders of color. The Houston-based firm recently closed its debut fund for more than $21 million. Learn more.

Ty Audronis and his company, Tempest Droneworx, made a splash at SXSW Interactive 2025, winning the Best Speed Pitch award at the annual festival. The company is known for it flagship product, Harbinger, a software solution that agnostically gathers data at virtually any scale and presents that data in easy-to-understand visualizations using a video game engine. Audronis says his company won based on its merits and the impact it’s making and will make on the world, beginning with agriculture. Learn more.

Houston-based Persona AI and CEO Nicolaus Radford continue to make steps toward deploying a rugged humanoid robot, and with that comes the expansion of its operations at Houston's Ion. Radford and company will establish a state-of-the-art development center in the prominent corner suite on the first floor of the building, with the expansion slated to begin in June. “We chose the Ion because it’s more than just a building — it’s a thriving innovation ecosystem,” Radford says.

Houston university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
