Bob Zlotnik Net Worth 2026: StarTex Power Co-Founder

No reputable publisher, including Forbes and Bloomberg, has released a net worth estimate for Bob Zlotnik, and the $625 million figure on older profile sites had no source. The biggest documented event in his finances is the 2011 sale of StarTex Power, the Houston electricity retailer he co-founded with his wife, Marcie, to Constellation Energy for about $160 million in cash. The couple also owned the Sugar Land Skeeters baseball team and kept a minority stake when the Houston Astros bought control in 2021.

What is Bob Zlotnik's net worth?

There is no sourced figure. The old page also called him the founder of Just Energy, which is wrong: Just Energy is a separate company, and the only link is that Marcie Zlotnik later joined its board. Its yearly, monthly and daily income numbers were invented and have been removed.

What can be said is that the Zlotniks sold a company for nine figures and have since given away millions. How much of the StarTex price went to them personally, after other shareholders and taxes, has not been reported.

Where the money comes from

StarTex Power

Texas opened its retail electricity market in 2002, and in 2004 Bob and Marcie Zlotnik started StarTex Power in Houston, according to Wikipedia. Bob was president and CEO; Marcie, who had co-founded the retailer Gexa Energy in 2001, was chair. In 2010 the company reported $407 million in revenue, Smart Business reported, and it served about 170,000 homes and businesses. It ranked first in customer satisfaction in a 2009 J.D. Power study.

In May 2011 Constellation Energy agreed to buy StarTex. Energy Choice Matters reported the announced price as $142.5 million in cash, with industry sources putting the full value near $170 million once working capital was included. Constellation's own SEC filing later recorded the purchase of Star Electricity, Inc. (StarTex) at approximately $160.4 million in cash. The StarTex brand was retired in 2018.

Sugar Land Skeeters

The Zlotniks owned the Sugar Land Skeeters from the team's start in 2012, when it began play in the independent Atlantic League at Constellation Field. The club won league titles in 2016 and 2018. In November 2020 the Houston Astros agreed to buy majority control and make Sugar Land their Triple-A affiliate; the deal was approved by the city in April 2021, and MLB said the Zlotniks would remain minority partners. The team is now the Sugar Land Space Cowboys. No price for the stake was disclosed.

BZMZ Interests

Zlotnik is managing director of BZMZ Interests, a family investment company with holdings in the automobile and hotel industries as well as sports, according to a Rotary Club of Richmond speaker bio.

Career timeline

Philanthropy

In 2014 the Zlotniks pledged $5 million toward Robert B. Rowling Hall, the graduate business building at UT Austin, and its ballroom was named the Zlotnik Family Ballroom. They had earlier given $1 million to set up a chair in entrepreneurship at McCombs, according to an announcement of the gift. Since November 2023 they have co-chaired Our Tower: The Next 100 Years, a campaign to restore the UT Tower that is set to run until late 2027, UT News reported in November 2025.

Bob Zlotnik's wife and family

Zlotnik is married to Marcie Zlotnik, his business partner. She grew up partly in Montreal, moved to Houston in high school and earned a BBA from UT in 1983. After StarTex she joined the boards of Just Energy in 2020 and NRG Energy in 2023. The couple have three sons, all UT graduates, and four grandchildren as of late 2025. Zlotnik's father was also a Longhorn and took him to football games as a child.

How old is Bob Zlotnik?

His date of birth has not been published in the sources we checked. He finished his BBA at UT in 1975. The old page's age of 75, height and weight had no source and were removed.

Net worth compared

Zlotnik's path resembles that of Mo Siegel, who co-founded Celestial Seasonings and sold it to a large corporation. For both, the sale is public but their personal share is not, and no reputable outlet has published a net worth.

Why no estimate is given

The StarTex price is known, but not the Zlotniks' ownership percentage, the tax bill, what they paid for the Skeeters, what the Astros paid for control, or what BZMZ Interests holds today. Without those, any single figure would be invented. This page will add one if a reputable publisher releases it.
