The Top B2B Lead Generation Companies in 2023

Last updated: September 14, 2023

Our team analyzed 80+ B2B lead generation companies, ranking them on 6 weighted factors:

  • Notable Clients (35%): A history of successful work performed for high profile clients is a strong indicator of lead generation expertise, and is the highest weighted factor in our algorithm.
  • Years in Business (25%): Lead generation companies that have weathered one or more economic downturns have demonstrated their ability to procure leads for their clients in less-than-ideal market conditions.
  • Company Size (20%): Company size is strongly correlated with lead generation ability, as few lead generation companies are able to grow without strong client relationships built on well-run campaigns.
  • Headquarters (10%): Companies in major cities have greater access to talent and professional connections, making headquarters location a minor factor in our ranking.
  • Specialty (10%): Lead generation can take many forms. We favor companies that specialize in reliable lead generation channels that result in high ROI for their clients.

The below table shares the results of our analysis.
