Maximum Effort Productions, Inc. is an American film production company and digital marketing agency founded by Canadian actor Ryan Reynolds alongside George Dewey in 2018. The company's name is a reference to a catchphrase from Reynolds' 2016 film Deadpool. In 2025, the company was named one of Time's 100 most influential companies.
Maximum Effort's marketing arm was acquired by advertising software company in June 2021, with Maximum Effort Marketing keeping its name while operating as an agency within MNTN. Reynolds was named MNTN's chief creative officer, and Dewey MNTN's chief brand officer. MNTN was founded in 2009 as Steelhouse, rebranding itself in 2021. In September 2024, Bloomberg News reported that MNTN was planning to Public company in 2025, with Morgan Stanley to organize its initial public offering; however, in MNTN's IPO filing (i.e. Form S-1) with the Securities and Exchange Commission, which was filed February 28, 2025, MNTN disclosed that it has agreed to divest "its interest in Maximum Effort to an affiliate of its original owner" and in connection with the transaction, MNTN provided a line of credit of up to $5.0 million, which was drawn upon. The sale closed on April 1, 2025. The filing also notes that MNTN will enter into a creative services agreement with Maximum Effort; however, as of May 14, 2025, no agreement has been reached.
Maximum Effort Productions projects include the musical Spirited, directed by Sean Anders and starring Reynolds and Will Ferrell. The company also produces the FX docuseries Welcome to Wrexham. In May 2021, Maximum Effort Productions closed a three-year first-look deal with Paramount Pictures for all their feature films. In August 2022, it was announced Maximum Effort would launch a free ad-supported streaming TV channel, which launched in June 2023 on FuboTV and other platforms. The first original program on the channel was entitled Bedtime Stories with Ryan and premiered June 20, 2023. In June 2023, it was announced that Maximum Effort had made a deal with Welsh language channel S4C to show six hours of Welsh language programming per week which Reynolds has referred to as "Welsh Wednesdays". The channel shut down in January 2025.
In February 2023, Maximum Effort announced the development of a 1.2 million-square-foot studio to be built in Markham, Ontario, Canada, just outside of Toronto. In March 2025, the company signed a first-look deal with 20th Television.
In December 2021, following the release of the Sex and the City revival series And Just Like That..., and the death of Mr. Big on a Peloton bike, shares in Peloton fell. Maximum Effort quickly devised an advertisement for Peloton featuring Chris Noth. Reynolds provided the voiceover promoting the health benefits that cycling can have, and noting that Chris Noth/Mr. Big was still alive.
The company has gained recognition for its ability to produce ads quickly, an approach Reynolds calls "Fastvertising." In 2025, Maximum Effort produced a "fastvertsing" response video starring Gwyneth Paltrow for Astronomer after a viral scandal involving its CEO.
