Influencer50 is a global B2B- and B2C-focused influencer identification and engagement management firm. Founded by Nick Hayes in 2004, the company operates globally from the US, UK and Australia, with its head offices in London and San Francisco.


Influencer50’s principal service is its Top50 Influencer Identification program, which as its name implies, identifies the 50 most important influencers within a particular market or service category. Each individual is ranked according to eight discrete criteria and is the result of offline, online and social research, market analysis, and ‘industry player’ assessment.

Influencer50 Identification

Influencers are classified according to one of approx. 30 different categories, ie. Journalist, Industry Consultant, Regulator, etc. Typically 10-15 categories are represented in the eventual Top50, emphasizing the fragmentation that’s occurred with who most influences business buying decisions over the past decade.

In addition to its Identification Programs, Influencer50 provides Influencer Engagement Programs and ongoing Influencer Relations Outreach.
