Liam O'Brien's net worth is not publicly verified. O'Brien is a co-founder and primary cast member of Critical Role, an executive producer of The Legend of Vox Machina, and a veteran actor, writer and director. Those positions establish a substantial entertainment career, but no reliable public record reveals his Critical Role ownership percentage, salary, profit distributions, acting contracts, assets or debts. A precise dollar estimate cannot be reproduced from the available evidence.
Websites commonly repeat a seven-figure estimate without showing a calculation. That number should not be treated as fact. Critical Role's company revenue, a crowdfunding total, an animated show's budget and O'Brien's personal wealth are different things. The defensible approach is to document the work that may generate income while being explicit about the financial information that remains private.

Why Liam O'Brien's Net Worth Is Unknown
Personal net worth requires more than career success. It is calculated from assets—such as cash, investments, real estate and business interests—minus liabilities. O'Brien has not published that information, and Critical Role does not disclose individual founders' capitalization, compensation or distributions.
Even a confirmed ownership interest would not automatically produce a reliable valuation. Critical Role is a private media company, so there is no continuously quoted share price. A private-company stake also is not the same as cash: its value would depend on the company's finances, agreements among owners, restrictions on selling and the terms of any transaction.
The same caution applies to acting and production work. A long credit list demonstrates employability and reach, but not take-home pay. Contracts can involve session fees, episode rates, reuse payments, directing fees, writing compensation and producer arrangements. Public sources reviewed for this article do not disclose O'Brien's individual terms.
Critical Role: Co-Founder, Cast Member and Producer
O'Brien's most important current business connection is Critical Role. The company's official Liam O'Brien profile describes him as a co-founder, primary cast member and executive producer of The Legend of Vox Machina. Critical Role's own company history names him among the original voice-actor founders.
Those descriptions are more useful than vague claims that he simply “works for” the show. Co-founding a private media company and serving as an executive producer may create several forms of compensation or long-term value. But the words co-founder and executive producer do not reveal his equity percentage, salary or distributions. No such numbers appear in the official profiles.
Critical Role also describes itself as an independent, creator-owned media company. That indicates a different model from an actor receiving only a fee from an outside studio, yet it still does not establish how ownership is divided among founders. It would be misleading to divide a company-level number equally among the cast or assign the entire value of the brand to any one member.
SuccessTitan also profiles fellow founding cast members Matthew Mercer, Sam Riegel and Laura Bailey. Their public visibility comes from the same franchise, but their contracts, outside work and private finances should be evaluated separately.
His Four Main Critical Role Characters
O'Brien has participated in all four main Critical Role campaigns, which gives his role unusual continuity within the franchise:
- Vax'ildan: the half-elf rogue and paladin he played in Campaign 1, later voiced by O'Brien in The Legend of Vox Machina.
- Caleb Widogast: the human wizard from Campaign 2 and one of the central figures in the Mighty Nein story.
- Orym: the halfling fighter of the Air Ashari in Campaign 3.
- Halandil “Hal” Fang: the orc bard and theatre figure played by O'Brien in Campaign 4.
Critical Role's official FAQ connects O'Brien to Vax'ildan, Caleb and Orym. Its current Campaign 4 character page identifies Halandil “Hal” Fang as his latest main-campaign character. These official records are preferable to fan-edited pages for establishing current roles.
The characters matter economically only in a limited sense. They show O'Brien's continuing creative importance to the franchise and support related performance and adaptation work. They do not reveal whether compensation is paid per episode, through company distributions, under producer agreements or in another form.
Voice Acting, Writing and Direction
O'Brien had a wide-ranging voice career before Critical Role became an independent media company. His official Critical Role biography says he has worked on more than 400 animation and video-game projects. It lists Gaara in the Naruto franchise, War in the Darksiders games, Gollum in Middle-earth: Shadow of War, Doctor Strange in multiple Marvel projects and several characters in Star Wars Rebels.
The same biography documents work outside the recording booth. O'Brien has worked as a voice director and writer on games including The Last of Us, The Witness, Evolve, World of Warcraft and Resident Evil 6. These are distinct professional services: acting supplies a performance, voice direction guides a cast, and adaptation or writing work shapes material for production.
Multiple categories of work broaden the ways an established performer can earn, but a project count is not a salary calculation. Some jobs may involve a small number of sessions, while others can extend across episodes, games or production cycles. Without contracts or union earnings statements, assigning an average fee to hundreds of credits would create a misleading total.
Readers comparing voice-acting careers may also find our Bryce Papenbrook profile useful. As with O'Brien, recognizable roles establish career activity more reliably than the unsourced wealth figures repeated by biography sites.
The Legend of Vox Machina and The Mighty Nein
O'Brien reprised Vax'ildan for the animated adaptation The Legend of Vox Machina and is listed by Critical Role as an executive producer. He is also connected to the animated The Mighty Nein adaptation through Caleb Widogast. These projects expand his work from an actual-play series into scripted animation.
Large production announcements are easy to misuse in net-worth articles. Money raised or committed to produce animation pays studios, artists, writers, performers, post-production teams and many other costs. It is not a dividend paid to one cast member. Without an individual contract or company distribution record, production scale should be reported as career context rather than personal income.
Writing Der Katzenprinz and Other Zemnian Tales
O'Brien expanded his writing work with Critical Role: Der Katzenprinz & Other Zemnian Tales. The official publisher page identifies O'Brien as the author, Charlie Borovsky as the illustrator, Insight Editions as the publisher and April 8, 2025, as the publication date.
The 112-page illustrated collection contains three fairy tales from Critical Role's fictional world. Authorship adds another documented professional channel to O'Brien's acting, directing and producer work. However, the list price and publication of a book do not disclose the author's advance, royalty rate, sales, returns or share of licensed-property revenue. The book therefore supports the career narrative but not a personal net-worth estimate.
How Liam O'Brien May Earn Money
Public records support several possible income categories, while leaving the amounts private:
- Critical Role performance: regular participation in the main campaigns and related programs.
- Private-company participation: his confirmed co-founder position may have economic value, but the ownership and distribution terms are undisclosed.
- Animation: voice performance and executive-producer work on Critical Role adaptations.
- Voice acting: hundreds of animation and video-game projects across established franchises.
- Writing and voice direction: production work on games and adaptations.
- Publishing: authorship of Der Katzenprinz & Other Zemnian Tales, under private publishing terms.
- Appearances and related work: live events and other professional engagements may generate fees, although no schedule is publicly disclosed.
This list should not be converted into a guessed annual income. It identifies documented professional activities, not the frequency, gross compensation, expenses or tax treatment of each category.
Liam O'Brien's Wife and Family
Professional biographies identify voice actor Amy Kincaid as Liam O'Brien's wife and report that they have two children. O'Brien's IMDb biography lists Kincaid and their children, while Critical Role's announcement for All Work No Play publicly refers to O'Brien balancing work with fatherhood.
These details answer the recurring “Liam O Brien wife” and marriage questions without extending into private information about the children. They also should not be used to combine two people's earnings or assume joint assets. A spouse's profession does not disclose the couple's balance sheet.

The Bottom Line
Liam O'Brien has built a diverse career across voice acting, direction, writing, publishing and a creator-owned media company. Official sources establish his co-founder and producer responsibilities, hundreds of projects, four main Critical Role characters and 2025 book. They do not establish his net worth. Until reproducible financial records appear, reporting an unexplained dollar figure would be less accurate than acknowledging what remains private.
