Inspect the highlighted sourceThe challenge
Scaling personalization without sacrificing quality remains elusive for sales engagement platforms; Apollo's thousands of customers, from startups to enterprise teams, needed genuine and relevant outreach rather than generic and impersonal messaging, and early experiments with other AI models fell short on writing quality and accessibility for users who don't want to spend all day thinking about outbound.
The solution
Apollo selected Claude after a blind test evaluating models on accuracy, clarity, relevance and tone, with Claude 3.5 Haiku achieving a 76% preference rate. Claude now powers Apollo's AI Copywriter Model generating personalized outbound emails and follow-ups, Signal Aggregation combining Apollo's database with external signals like news and hiring patterns, Voice and Tone Matching that learns each salesperson's writing style, and dynamic content generation in all of Apollo's pre-built messaging templates.
