MarketMuse, founded in 2013, was among the earliest platforms to apply machine learning and natural language processing to content strategy, predating several now-familiar competitors in this category by years, and built a reputation on automated content inventories, AI-driven content planning, and a large keyword database gained through its acquisition of Grepwords.
In October 2024, MarketMuse entered a definitive agreement to be acquired by Siteimprove, a company covering analytics, accessibility, and cross-channel advertising, folding MarketMuse's content-intelligence capability into that broader suite rather than continuing as a fully independent standalone product.
A free tier covers limited use, with paid plans available for deeper content planning and optimization. For a team that wants a pioneering, long-refined content-intelligence methodology, now backed by a broader Siteimprove suite covering analytics and accessibility alongside content, MarketMuse's combination of deep history and newer corporate backing addresses that specific mix.
