Harp vs 11x
11x sells AI workers: Alice for outbound and Julian for inbound, working across email, social, voice, chat, SMS and WhatsApp, with deliverability managed in house. Harp takes the opposite approach: you bring the agent, and Harp is the harness it works through.
The short answer
If you want a vendor’s AI workers to run outbound and inbound for you across many channels, including voice, 11x is built for that. If you already use an AI agent and want it to run outbound with your judgment, your plan and your own LinkedIn session, Harp is built for that.
Side by side
| Topic | Harp | 11x |
|---|---|---|
| What it is | The MCP harness for pipeline generation: research memory, sequences, sending, replies and LinkedIn, driven by your AI agent | AI workers: Alice (outbound) and Julian (inbound) |
| Whose AI | Your own agent (Claude today) on your own plan; no AI credits | 11x’s own agents |
| Channels | Email and LinkedIn | Email, social, voice, chat, SMS and WhatsApp, plus a human dialer |
| 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 | “Social” is listed as a channel; check 11x for how LinkedIn is handled | |
| Replies | The sequence stops; your agent answers email replies and books the meeting within minutes. LinkedIn replies wait for your yes in Slack | Julian answers inbound by voice and chat; check 11x for outbound reply handling |
| Buying | Flat subscription after a short call; set up with you | Demo-led; no public pricing |
Handing over vs bringing your own
11x is built for teams that want to hand outbound to a vendor’s AI and get a finished system across many channels, voice included. Harp is built for teams whose own agent already does good work and needs a harness: research memory, sequences, sending, reply handling and LinkedIn at human pace.
When 11x is the better choice

- You need voice, chat, SMS or WhatsApp.
- You do not use an AI agent and do not want to.
When Harp is the better choice
- Your team already works with Claude and wants it doing outbound.
