Zak Williams Net Worth: Mental Health Advocate, Entrepreneur, and Robin Williams’ Son.
In the diverse landscape of celebrity net worth, where the children of legends like Paris Jackson (Michael's daughter) forge their own paths, and self-made stars like Bill Burr build comedic empires, Zak Williams (Zachary Pym Williams) stands out with a unique story.
The eldest son of the beloved comedian Robin Williams, Zak has built an estimated net worth of $18 million, a figure stemming from both a significant inheritance and his own impactful career.
As a dedicated mental health advocate, entrepreneur, and investor, Zak launched PYM (Prepare Your Mind) in 2020 with his wife, Olivia June, a company aptly named after his middle name. He continues his profound advocacy through projects like The Net, a documentary focused on preventing suicides at major structures, deeply reflecting his commitment to issues connected to his famous father's enduring legacy.
Most recently, on what would have been Robin Williams' 74th birthday, Zak shared a poignant message on Instagram, reminding "anyone carrying loss right now" that "you're not alone," and that the best way to honor those we've lost is by living the "values they stood for" and finding "paths of light, even in the dark corners" as reported in People.com (July 22, 2025).
Zak Williams' Financial Journey: Inheritance and Entrepreneurial Success

Zak Williams' estimated net worth, understood to be around $18 million, is a combination of a significant inheritance from his father, Robin Williams' substantial estate, and his own successful entrepreneurial and investment activities.
Upon Robin Williams' passing in 2014, his estate was widely reported to be valued at an estimated $100 million, as detailed in reports regarding the subsequent estate dispute from sources like Insight Law. However, the distribution of this wealth was subject to various financial deductions and legal arrangements.
Our analysis, based on standard legal and tax practices for estates of this size, indicates the initial $100 million estate faced considerable reductions from its gross value.
These included an estimated federal estate tax of approximately $37.9 million on the portion exceeding the 2014 exemption of $5.34 million, as the federal estate tax rate was 40% for estates over $1 million, according to tax information from sources like James F. Roberts & Associates, APC.
Additionally, the highly publicized legal dispute between Robin Williams' widow, Susan Schneider Williams, and his children likely incurred substantial legal fees, which we estimate at around $3.5 million, a figure consistent with costs for complex estate litigation as discussed by legal resources like Nolo.
Trust administration costs, typical for complex, high-value trusts, could have amounted to approximately $6.3 million over the years, based on an estimated 1% annual fee on trust assets, a rate commonly cited by financial institutions like Hancock Whitney for trust maintenance. While precise terms are private, a portion of the estate, estimated at $4 million over a 20-year period, would have been allocated for Susan Schneider Williams' living expenses and continued occupancy of the Tiburon home.
After these considerable deductions, the remaining portion available for Robin Williams' three children—Zak, Zelda, and Cody—is estimated to be around $48.3 million.
Zak, being 31 at the time of his father's death (as widely reported by various news outlets), had already received his full one-third share of this primary trust, estimated at approximately $16.1 million. This was distributed in staggered payments over time, with portions at ages 21, 25, and the full amount at 30, as reported by outlets covering the trust details like South Bay Elder Law and KJM Law.
Furthermore, the eventual sale of the Tiburon home in 2020 for $5.35 million, as confirmed by real estate reports from sources like People, contributed an additional estimated $1.8 million to Zak's inheritance, as the children were the ultimate beneficiaries of the property. This robust foundation from his father's legacy, combined with his ventures like PYM and his investments, forms the core of Zak Williams' current financial standing, contributing to his estimated $18 million net worth.
A Father's Enduring Legacy: Robin Williams' Profound Impact on Zak's Life

Robin was openly proud of all his children, and his compassionate spirit clearly impacted Zak's upbringing.
The tragic passing of Robin Williams in August 2014 was a pivotal, heartbreaking moment.
