Section 2 Valley = AI SDRs Without the Complexity

2025 Cost & Performance Reality Check

The Human SDR Model Is Financially Broken

In 2025, the average U.S. SDR costs $98,500/year fully loaded—and only 15.5% hit quota. With 78% annual attrition, most reps burn cash for 7 months before breaking even.

Yet outbound pipeline is non-negotiable. So what’s the alternative?

AI SDRs for LinkedIn outreach promise 80% cost savings and 2X activity volume. But real-world execution reveals hidden pitfalls and complex tradeoffs.

The Case Against Human SDRs

Expense Category	Avg. Cost (USD)
Base Salary	\$55,000
Commissions & Benefits	\$30,000
Tech Stack (avg. 6 tools)	\$13,500
Total per SDR	\$98,500

Only 5.1% of daily human SDR touches convert. That’s $23.47 per touch and $459.80 per conversation.

And generic messaging has consequences—68% of buyers say it damages brand perception.

Section 2

AI SDR platforms slash monthly spend to $1,200–$5,000, with daily activity volumes 10–20X higher than human SDRs.

But the real total cost of ownership includes:

$1,800/mo for IP warming & inbox repair
$950/mo in third-party enrichment
22 dev hours/month for integration upkeep

And poor AI personalization? It backfires hard.
