Summary

SaaStr ran AI SDRs across multiple platforms for a year and found the highest-ROI use case is reactivating leads human reps ignore — ghosted CRM contacts, old event attendees, cold website visitors. Volume increases of 11-40x over human SDRs are real, but message quality requires 30+ days of daily tuning, human-written templates, and ongoing spot-checking to avoid burning domain reputation.

Key Insight

  • Ignored leads are the sweet spot. AI SDRs generated 15% of SaaStr London event revenue from a segment that would have produced zero without AI — previously ghosted CRM contacts hit a 72% open rate via Agentforce.
  • Volume numbers are staggering but misleading without quality context. Artisan sent 3,221 emails/month vs 75-285 per human rep (11-40x). Response rates: 5.5% on cold, 11-12% on warm. The 11-13x response multiplier only holds if ICP targeting is sharp.
  • Inbound AI SDR has the clearest ROI proof. Qualified generated 1 010 000 USD closed-won in 90 days from 668,591 sessions (91 meetings). 71% of one month’s closed-won came from AI-qualified inbound vs a historic baseline of 29-34%.
  • The “afternoon setup” claim is a lie. Real timeline: 2-4 weeks ICP/messaging prep, 1-2 weeks integration, then 30-45 min/day tuning for the first 60-90 days. They went through 47 iterations just to fix aggressive pricing language and manually reviewed the first 1,000 emails.
  • Templates must be human-written. Best approach: your top-performing SDR writes 5-7 frameworks based on deals that actually closed, then AI personalises on top. Keep under 75 words. Never let the vendor write them.
  • Handoff design is non-negotiable before launch. AI creates an expectation of instant responsiveness — if the human handoff is slow, you lose the deal the AI generated.
