A GTM-Ready Guide for B2B SaaS

In 2025, the traditional SDR model is unsustainable. Outbound conversion rates have plummeted to 0.1%, while SDR salaries average $55K/year. It now takes 1,000–1,500 activities to create a single opportunity. Meanwhile, AI-generated outbound messages are projected to account for 30% of all outreach this year—a 98% increase since 2022.

For B2B SaaS sales leaders, AI SDR tools aren't optional—they're the only path to scalable, personalized, and cost-effective pipeline generation.

What Is an AI SDR?

An AI SDR (Sales Development Representative) is software that automates and enhances outbound sales tasks using artificial intelligence. These tools handle lead research, outreach personalization, follow-ups, and engagement tracking, allowing human SDRs to focus on high-value interactions.
