Last updated: May 30, 2024

Our team recently 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.
