Per-AI-Worker Autonomous
Vendors: 11x (Alice from $3,750/mo), Artisan (Free/$280/$660 Ava)
Deploy an autonomous AI worker (BDR/SDR). Both publish an entry price and quote the top tier: 11x meters Alice by new prospects per month, Artisan meters Ava by credits.
Pros
- +Fully autonomous -- no human in the loop
- +End-to-end: identify + enrich + compose + send + reply + book
- +Fixed cost regardless of how hard you work the allowance
Cons
- -11x's published floor is the highest entry price in this set
- -Metered by prospects or credits, so an unused allowance is money gone
- -Annual billing by default at 11x; 2-3 year terms above Growth

FAQ: AI SDR Pricing Models
Which AI SDR pricing model is cheapest at 5,000 contacts per month?▼
At 5,000 contacts per month: AiSDR's top self-serve tier (Scale, $2,500/mo) covers 2,500 AI-researched contacts, so 5,000 means a custom quote or two units; Apollo Professional ($79/user/mo for 3 reps = $237/mo but with per-credit limits on enrichment) is the per-seat comparison. HubSpot Breeze at $1/qualified lead costs $500-$5,000 depending on your ICP qualification rate. Clay Growth at $495/mo covers data enrichment for 5K contacts but requires a separate sending tool at additional cost. No single model wins -- the math depends on your seat count, volume consistency, and CRM stack.
What is outcome-based pricing for AI sales agents?▼
Outcome-based pricing means you only pay when the AI achieves a defined result. HubSpot Breeze Prospecting Agent's $1 per qualified lead (announced 14 April 2026) is the only major AI sales agent with published outcome-based pricing at this level. You pay $1 for each contact the AI identifies as a qualified outreach target; no qualified leads identified, no charge. This contrasts with per-message (you pay for every send regardless of quality) and per-seat (you pay monthly regardless of actual usage).
How do I calculate the true annual cost of a per-seat AI SDR?▼
True annual cost formula: (Seat price per user per month x number of users x 12) + seat minimum adjustment + implementation fee + platform fee + add-on costs. For Apollo Organization at 5 reps: ($119 x 5 x 12) = $7,140/yr seat cost + $0 implementation + $0 platform fee. Apollo Organization carries a 3-user minimum, so a 5-rep team is already above the floor, but a 2-rep team would still pay for 3 seats ($119 x 3 x 12 = $4,284/yr). Contact-sales per-seat tools such as Outreach publish no per-seat rate, so confirm the seat price and any platform fee in the quote before you model the annual cost.
