Harp vs AiSDR
AiSDR runs outbound with its own AI, Ami, across email, LinkedIn and AI voice notes, with lead data included and a pay-as-you-go option priced per person prospected. Harp lets your own agent do the work.
The short answer
If you want an AI SDR you can start today and pay for per prospect, with data included, AiSDR is built for that. If you want your own agent to run outbound, with research saved as evidence and LinkedIn run from your own Mac, Harp is built for that.
Side by side
| Topic | Harp | AiSDR |
|---|---|---|
| What it is | The MCP harness for pipeline generation: research memory, sequences, sending, replies and LinkedIn, driven by your AI agent | An AI SDR platform with its own AI (Ami) |
| Whose AI | Your own agent (Claude today) on your own plan; no AI credits | AiSDR’s own AI |
| Lead data | Not sold; your agent uses the tools you already use | Included in the subscription |
| Channels | Email and LinkedIn | Email, LinkedIn (connections, messages, InMail), voice notes and AI video |
| Steps run from your real Chrome on your Mac at the OS level: click navigation, daily limits, a four-week warm-up and a right-person check | Connection requests, messages and InMail; check AiSDR for how it connects | |
| Buying | Flat subscription after a short call; set up with you | Pay as you go at $1.50 per person prospected, or quoted team plans |
Per-prospect AI vs your own agent
AiSDR prices the AI’s work per person prospected, with research, lists and writing included. Harp runs no model on your outreach: your own agent does the research and writing on your plan, and Harp is a flat subscription for the harness around it.
