If you bought into the AI SDR hype in 2024, you weren't wrong to be excited.
The promise was compelling: Replace a $110K fully-loaded SDR with a $15K autonomous agent. Lower CAC by 80%+. Scale outbound without scaling headcount.
But for many GTM teams, 2025 has delivered a reality check.
Instead of autonomous revenue, we're seeing a growing trough of disillusionment:
Catastrophic churn. Aggregated data shared with us by customers and partners confirms what we're hearing in every GTM conversation: 50–70% of AI SDR deployments churn within the first year — nearly double typical human SDR attrition. At some high-profile vendors, that number has reached 80%. Conversion rates across AI-powered outbound have dropped from 1–2% to 0.5–1.5% in similar cohorts over the past year.
Domain burnout. "Spray and pray" automation is triggering spam filters and crushing deliverability. Google and Yahoo's 2024 authentication rules now reject non-compliant senders at the SMTP level. One spam trap hit can cut your inbox placement by 50% overnight.
The Janitor Effect. Human SDRs now spend their time cleaning up AI-generated mistakes — rewriting robotic emails, apologizing to prospects who received tone-deaf outreach, and repairing brand damage instead of building pipeline. The tool that was supposed to free them has become their biggest time sink.
So what's actually going wrong?
It's not that LLMs can't write good English.
It's that most AI SDR systems are stateless.
In computer science, a stateless system treats every interaction as an isolated event. It has no memory of what came before, no understanding of what's happening elsewhere in the relationship.
But B2B sales is fundamentally stateful. It depends on history, relationships, timing, and nuance.
When a stateless system runs outbound, context gets lost:
- It emails a prospect who's actively escalating a P1 support issue with your team
- It pitches a feature you deprecated last quarter — or one that doesn't exist at all
- It "invents" case studies because the model optimizes for plausibility, not truth
- It references a "recent Series B" that happened three years ago
One team told us their AI SDR pitched a partnership case study to a prospect whose company had publicly ended that partnership in a lawsuit. The prospect replied. It wasn't to book a meeting.
The result isn't scale — it's systematic erosion of trust.
The uncomfortable insight
The recent implosion of high-profile AI SDR vendors isn't surprising when you understand the underlying architecture.
In our analysis, ~80% of AI SDR failures are architectural, not model-related.
Most teams are over-indexing on vector-only retrieval as a substitute for system state. These systems can find similar-sounding information — but they cannot reason about relationships between accounts, contacts, conversations, and outcomes.
Probabilistic recall ≠ deterministic understanding.
In plain terms: your AI can retrieve text that pattern-matches the query. But it cannot actually know what's true about this account, this person, this moment in the relationship. Truth lives in systems of record, not embeddings.
Sales execution demands the latter.
Until your AI understands why a deal was won, what was said in the last support escalation, and how this prospect connects to your best (and worst) customers — it's not selling. It's guessing at scale.
What comes next
We're entering a recalibration phase. "AI that sends emails" is table stakes — and increasingly, table stakes that burn your domain and your brand.
The winners will be teams that treat context, memory, and decision history as first-class infrastructure, not afterthoughts bolted onto a prompt.
In the next post, I'll break down:
- Why vector-only architectures fail in high-stakes sales execution
- What systems built on structured decision context do differently
- The specific patterns we're seeing in teams that have made AI SDR actually work
The question isn't whether to use AI in outbound. It's whether you're building on architecture that can actually handle the job.
