The news
AI SDR tooling is the fastest-growing line item in B2B go-to-market budgets this year. A fresh round of funding announcements and case studies last week — most claiming 3-10x pipeline lift with “autonomous” email generation and prospect research agents.
My take
Most of it is overpriced automation dressed in agent clothing.
I tested this directly. Last quarter we ran 458 leads through a live outbound campaign using three of the top-billed AI SDR tools plus our own stack (Lemlist + Clay + waterfall enrichment + LLM research). Reply rates:
| Stack | Reply rate |
|---|---|
| AI SDR tool A | 0.4% |
| AI SDR tool B | 0.9% |
| AI SDR tool C | 1.1% |
| GTMify stack (Lemlist + Clay + waterfall + LLM research) | 2.8% |
The AI SDR tools aren’t bad. They’re just priced like agents and perform like sequencers.
Here’s the pattern I see underneath the benchmarks: the tools that earn their price treat the research phase as the product, not the sending phase. You can buy sending cheap — Lemlist, Instantly, Smartlead, any of them. Sending is a commodity. What’s not a commodity is signal depth: knowing who this person is, what their company is doing right now, why today is the day worth reaching out. That’s where the real token budget should go.
Most AI SDR tools have this inverted. They spend the bulk of their compute on copy generation — writing variants of "I noticed you're the VP of Sales at [Company]..." — and almost none on the research that would make the copy actually work. Copy without specificity is noise. If a message could plausibly be sent to anyone in your TAM, it will be ignored by everyone in your TAM.
The so-what
Take the money you’re about to spend on an AI SDR subscription this quarter and split it. Half goes to a proper research layer — Clay + waterfall enrichment + an LLM tasked with real account research. The other half goes to a competent sender — Lemlist, Smartlead, anyone that isn’t charging you agent prices for commodity infrastructure. Run 100 leads through that stack before you commit. If your reply rate is north of 2%, you’ve found your answer. Sending is a commodity. Research is not. The vendors selling you the inverse pricing model are selling you the wrong end of the workflow.
