During a recent Town Hall session at WordCamp Canada 2025, Matt Mullenweg, the CEO of Automattic, openly acknowledged that his company’s acquisition of Tumblr stands as his ‘biggest failure’ to date. Despite the challenge of managing over half a billion blogs on a platform that continues to operate at a loss, Mullenweg remains committed to finding a solution.
Mullenweg revealed that his initial plan to transition Tumblr’s backend to WordPress infrastructure has been postponed due to the significant costs involved. The expenses of migrating Tumblr’s vast content outweigh the platform’s revenue, making it a complex and costly endeavor.
Efforts to streamline operations and reallocate resources within the company have not yet yielded the desired results. Mullenweg admitted, ‘It’s probably my biggest failure or missed opportunity right now, but we’re still working on it.’
If the migration to WordPress does eventually occur, it would not only simplify maintenance but also enable Tumblr to integrate more seamlessly with the open social web ecosystem known as the fediverse.
In light of these challenges, Automattic has refocused its priorities to ensure Tumblr’s sustainability. Despite setbacks, Mullenweg’s determination to address the issues plaguing Tumblr underscores his resilience and commitment to innovation within the blogging landscape.
