Want to try AiSDR?

AiSDR — autonomous outbound that books meetings without the SDR seat

AiSDR runs the cold-email cycle end-to-end: prospecting, personalization, sending, reply-handling. Pricing is usage-based (per-conversation, not per-seat) which is the right shape for early teams testing AI SDR before they hire — and the cost-per-meeting math typically beats $80–120K/yr SDR comp before benefits.

What is AiSDR?

AiSDR is an autonomous outbound platform that runs the full SDR cycle: prospecting, personalized cold email, send pacing, reply handling, and meeting booking. Pricing is per-conversation rather than per-seat, which is the right shape for early teams testing AI SDR before they hire.

Who it's for: Founders running their own outbound, lean RevOps teams under 30 reps, and growth-stage companies running an AI-SDR proof-of-concept before adding human SDR headcount.

Core Use Cases

Autonomous cold email — prospecting, personalization, sending, reply handling
Inbound qualification — auto-respond to form fills and book qualified meetings
Multi-channel sequences combining email + LinkedIn outreach
Replacement for offshore BDR teams or first-SDR-hire experiments

Pricing Overview

Usage-based: pricing scales with conversations handled rather than per seat. Typical SMB plans start around $750-$1,500/mo for ~1,000 conversations and scale up by volume.

Strengths

Per-conversation pricing aligns cost with output (vs flat per-seat AI SDR competitors)
Operator-friendly UX — first campaign live in hours, not weeks of solutions-engineer onboarding
Built-in HubSpot and Salesforce sync; works inside existing CRM workflows
Reply-handling AI is a core feature, not an add-on — most competitors stop at first-touch

Weaknesses

Newer entrant vs 11x — less brand recognition with enterprise procurement
AI personalization quality plateaus on accounts with thin public surface area
Multilingual coverage narrower than 11x
Conversation-based pricing can spike when reply rates are higher than modeled

Best Alternatives

When to Use It

Pre-first-SDR-hire founders testing whether outbound has product fit before adding headcount
Lean RevOps teams that need volume + reply handling without hiring 3 SDRs
Reply.io or Apollo customers hitting the limits of templated sequences

When NOT to Use It

Multilingual outbound is a hard requirement (11x has wider language coverage)
Your motion is account-based with high-touch named-account research (humans still win)
Procurement blocks AI-content tools without explicit policy review

StackSwap Insight

AiSDR is the calmer alternative to 11x in the AI-SDR category — less brand visibility, fewer co-founder departures, and conversation-based pricing that maps more cleanly to ROI math. We list it for operators who want the AI-SDR motion without betting on a turnaround. Pair with a real CRM (HubSpot, Salesforce, or Attio) — AiSDR sends, but your CRM still owns the source of truth.
