A material science startup with technology originating at Rice University has announced it has closed its seed round of funding.

DexMat raised $3 million in funding in a round led by Shell Ventures with participation from Overture Ventures, Climate Avengers and several individuals. The company transforms hydrocarbons, renewable fuels, and captured carbon into its flagship product Galvorn.

“DexMat presents an opportunity to capture methane, an abundant and inexpensive resource, and use it to replace materials such as steel, aluminum, and copper with a more sustainable option. We are excited to be part of DexMat’s journey going forward and to realize their ambitions,” says Aimee LaFleur, investment principal at Shell, in a news release.

Alongside the announcement of the seed round, DexMat has named Bryan Guido Hassin as its new CEO. Hassin, who was previously a member of the company's board of directors, has been at the helm of multiple climate tech startups and most recently co-founded Third Derivative. Dmitri Tsentalovich, the previous CEO, is transitioning to CTO.

“Before joining DexMat, as CEO of Third Derivative, I was introduced to easily over 2,000 innovative new concepts and technologies. DexMat’s solution was one of the most impactful I came across, which is precisely why I’m so excited to be joining the team,” says Hassin in a news release. “The opportunity to eventually cut up to 3 gigatons of CO2 annually in one of the most underserved markets of the clean energy transition — heavy industry — was too important for me to pass by.”

The product impacts the climate tech space on two levels. First, in the production process, the carbon is 'locked' into the Galvorn material structure as a form of long-term carbon storage, according to the release. On the use side, the material displaces carbon-intensive materials — like steel, aluminum, and copper.

"The world's net zero future is entirely dependent on electrifying everything and decarbonizing the built environment," says Shomik Dutta, co-founder and managing partner at Overture Ventures, in the release. "Metals like copper and steel sit at the heart of these trillion-dollar markets, and DexMat's technology promises carbon-negative, lighter, and stronger versions of what we currently mine and melt. Companies like this can help cement America's leadership in the most important transition of our lifetimes."

DexMat was founded to commercialize materials science technology that originally developed in the Rice University laboratory of co-founder Professor Matteo Pasquali. According to the release, the company was built on over $20 million in non-dilutive funding — including grants from from the Air Force Research Laboratory, Air Force Office of Scientific Research, U.S. Department of Energy, NASA, Advanced Functional Fabrics of America, and the National Science Foundation — with Rice University included in the list of original investors.

Houston wealth management adviser weighs in on benefit options as key for small business success

guest column

While Small Business Appreciation month has come to an end, my work in aiding small businesses achieve financial success is continuous.

In 2009, I began my career as a financial adviser recently co-founded Volante Integrated Planning, a Houston-based office of Northwestern Mutual focused on comprehensive financial planning and helping clients achieve financial freedom.

After years of working with business owners, and as a small business owner myself, I have learned the importance of offering benefits that help attract and retain talent, foster improved work habits and provide a foundation for growth. According to the annual SHRM employee benefit survey, health-related benefits and retirement plans were ranked the two most important benefits for employees. Whether you are a new small business owner or an established one, it is important to be aware of the benefit options available to you and the considerations that go into mapping out a benefits strategy.

1. Retirement plan options

The most common retirement plans available to small business owners are 401(k), simplified employee pension (SEP) IRA and savings incentive match plan for employees (SIMPLE) IRA. The SEP IRA and SIMPLE IRA provide employers the ability to save on a pre-tax basis. While there are some required contributions on behalf of any full-time employees, the SEP and SIMPLE IRA’s are often recommended for the self-employed or businesses with part-time or contract employees. The 401(k) also provides employers with a pre-tax savings opportunity and the ability to save on a Roth basis. Because a 401(k) requires additional administration and ongoing requirements, it is often a valuable tool for business owners who have more full-time employees.

2. Health care benefit options

According to the Affordable Care Act, companies with fewer than 50 employees are not required to provide health insurance. However, offering a competitive health insurance benefits package is an increasingly important strategy to help boost both new employee acquisition and retention. Following the global pandemic, health benefits have become increasingly important. According to a study by McKinsey & Company, 51 percent of employers now offer health care benefits to attract new employees with dental, vision, and short-term disability as the most important for job-seekers.

Not only are these benefits of importance to employees, they provide protection for business owners by ensuring good health and protection from illness-related lost productivity. Some health care benefits available to small business owners include health reimbursement accounts, where you make contributions to an account that can be used by employees to pay for individual health insurance policies acquired on their own. Consider hiring a broker, benefits consultant or financial adviser to help compare your options.

3. Life and disability insurance options

As a small business owner, you have a duty to your family, employees and business partners. It is often the unexpected that can derail the success of a business. To that extent, taking the steps to ensure you and your business are protected if you are unable to work is important. Disability insurance is a versatile product that can be used to protect you, as the owner, and your employees against loss of income due to the inability to work. Additionally, disability overhead coverage and disability buy-out insurance can protect the business and any business partners from an owner’s disability, ensuring that the business can still run smoothly. Life insurance is also important, and often required if seeking a business-related loan, to provide income replacement for your family and any business partners in the event of an owner’s death.

4. Get creative with your benefit options

The small business world is ever changing, which is why it is essential — and sometimes difficult — to keep up with benefit options. I encourage small business owners to get creative with their benefit options by exploring a professional employer organization (PEO) and a multiple employer welfare arrangement (MEWA). PEO is designed to help small businesses manage their administrative overhead, benefits and compliance duties. Through MEWA, small businesses are able to collaborate on group insurance benefits for a low cost. Lastly, if your family members contribute to your small business, make sure they are on the payroll and eligible for various benefits. This may allow you to increase the benefits your household takes home.

While creating a small business employee benefits plan can be tedious, it will take your small business to the next level. Consult in a CPA, business attorney, and financial adviser to help navigate what benefits are a good fit for you and your small business.

Disgraced Theranos CEO Elizabeth Holmes begins prison sentence just 90 minutes from her hometown of Houston

coming holmes

A longtime Houstonian is coming home — by way of prison.

Elizabeth Holmes, the disgraced founder of blood-testing startup Theranos, reported to F.P.C. Bryan, on Tuesday, May 30, per multiple news outlets. She is set to serve 11 years and three months in the women's minimum-security prison located some 90 minutes from Houston hometown.

According to the the New York Times, the onetime Tanglewood resident arrived at the prison in a Ford Expedition that appeared to be driven by her mother, Noel Holmes. Her father, Christian Holmes, appeared to be inside.

The Times adds that after some shuffling around, out of the view of the cameras gathered nearby, Holmes entered the facility wearing jeans, glasses and a sweater, and carrying some papers.

Prior to her arrival in Bryan, Holmes, 39, spent Memorial Day weekend with her family on the beach near her oceanfront San Diego home with her partner Billy Evans and their two children, according to the Daily Mail.

As CultureMap previously reported, Holmes was sentenced to more than 11 years in prison on November 18, 2002 in San Jose, California following her conviction in January that year for defrauding Theranos investors.

Actress Amanda Seyfried, who played Holmes in the Hulu series The Dropout, shared her thoughts on the woman she portrayed to great acclaim. “Life’s not fair,” Seyfried noted on Good Morning America on Tuesday, “but in a lot of ways, it’s fair. For her, in particular.”

Thrust into the spotlight as the new face of white-collar, Silicon Valley fraud, Holmes now serves as a warning to those who might consider a similar path, her sentencing judge made clear.

“I suppose we step back and ask what is the pathology of fraud? Is it the refusal to accept responsibility or express contrition in any way?" Judge Edward Davila said during the ruling, according to Yahoo! Finance. "Perhaps that is the cautionary tale that will go forward from this case."

Davila ordered Holmes to turn herself into custody on April 27, 2023.

Specifically, Holmes' sentence is 11 years and three months in prison, with another three years of supervision after release. Additionally, Holmes and her ex-boyfriend and former Theranos COO Ramesh “Sunny” Balwani have been ordered to pay $452 million to their fraud victims.

Once compared to disruptors and innovators Steve Jobs and Bill Gates, Holmes rose to fame by enticing investors with the promise that her Theranos could run hundreds of blood tests via a simple pin prick. Buzz for Theranos grew to the point that Theranos was valued at $9 billion, which made Holmes the world’s first self-made female billionaire.

Yet, after securing more than $900 million in funding, Theranos was proven to be essentially bogus by the Wall Street Journal in 2015.

Facing up to 20 years in prison, a tearful Holmes, who is pregnant, addressed the court. "I stand before you taking responsibility for Theranos," she said, per Yahoo. "I loved Theranos. It was my life’s work. My team meant the world to me. They wanted to make a difference in the world. I am devastated by my failings," she said. "Every day for the past years, I have felt deep pain for the people…those people who believe in us and those patients. I worked so hard to serve. I gave everything I had to try to to build...Theranos. Looking back, there are so many things I would do differently. I tried to realize my dream too quickly."

Holmes is the subject of the aforementioned series, The Dropout, which centers on her early life in Houston, where she grew up in Tanglewood and attended St. John's School. Her father's layoff from Enron is presented as clearly an inciting incident in her life. As The Dropout depicts, Holmes would meet boyfriend/partner Ramesh "Sunny" Balwani, drop out of Stanford, and launch Theranos.

One of the most memorable lines in the miniseries comes when a young Holmes plainly states her goals at a family gathering. "I wanna be a billionaire," she said plainly — a memorable and clearly prophetic statement.
