In 2008, performance marketing was becoming increasingly fragmented. Ad networks were taking credit for conversions they didn’t fully drive, and most agencies were optimizing media against network-reported numbers and calling it performance. We didn’t trust those numbers. So we created our own measurement layer. What began as internal infrastructure evolved into Atrilyx — built on patented attribution technology, powered by Ai that connects channels, devices, and conversions into one reconciled source of truth. Every media decision we make runs through it. Every client engagement benefits from it. Nearly two decades and more than $1B in managed media decisions later, the problem still exists. The networks still grade their own homework. We still don’t let them.

Frequently Asked Questions About Lead Generation
What does a lead generation agency do?
Lead generation agencies identify and attract potential customers for businesses through targeted marketing campaigns, data enrichment, and multi-channel outreach strategies. They create qualified leads using tactics like cold email outreach, LinkedIn prospecting, content marketing, landing page optimization, and CRM management. These agencies focus on filling sales pipelines with high-intent prospects who are more likely to convert into paying customers.
How much do lead generation services cost?
Lead generation service costs typically range from $2,000 to $15,000+ per month depending on campaign complexity, target market, and lead volume requirements. Many agencies offer performance-based pricing models charging $50-$500 per qualified lead, while others use retainer-based structures for ongoing demand generation campaigns. Factors affecting cost include industry competitiveness, lead qualification criteria, and the number of marketing channels utilized.
How do I choose the right lead generation agency?
Select a lead generation agency based on their proven track record in your industry, transparent reporting practices, and expertise with relevant technologies like CRM integration and marketing automation. Evaluate their lead qualification processes, data enrichment capabilities, and multi-channel approach including cold outreach, inbound marketing, and social selling. Look for agencies that provide clear metrics on lead quality, conversion rates, and ROI rather than just lead volume.
