11x

11x is the AI rep most people reach for when they hear “autonomous SDR” and picture something genuinely enterprise. Its agent, “Alice,” runs outbound across email and LinkedIn, and a separate voice agent, “Julian,” takes it onto the phone — which is what gives 11x the widest channel mix in the Index. If your motion needs voice as well as email, this is the short list of one.

It also comes with the bill you'd expect. Pricing starts around $1,500/mo and is genuinely custom — you're booking a demo, not swiping a card — and the voice agent is priced separately on top. So the honest framing is: 11x is what you buy when channel breadth and enterprise polish matter more than the sticker price.

What it does well

The channel coverage is the headline, and it earns it. Email, LinkedIn, phone and SMS in one coordinated agent is rare, and the voice piece is the differentiator nobody else in the Index really matches. For an enterprise team that wants outbound to actually pick up the phone — not just fire another email sequence — that breadth is the whole pitch, and it's real.

The autonomy is strong too. Alice is a properly hands-off agent: it sources from a built-in database (with the option to bring your own), researches, writes and sends without you babysitting each step. In our scoring it sits at the top of the autonomy factor alongside the other leading reps — this is delegation, not a sequencer with a chatbot bolted on.

And the enterprise wrapper is the quiet reason 11x wins deals. Security review, guardrails, CRM-native flows into Salesforce and HubSpot, and a CSM you can actually call. For a company that has to clear a procurement and security process before anything touches its pipeline, that's not a nice-to-have — it's the reason a smaller, cheaper tool never makes the shortlist.

Where it's weaker

Two things to weigh honestly. The first is price: enterprise-tier and custom, with voice as a paid add-on, so the all-in cost climbs faster than the entry number suggests. That's reflected in 11x's value factor, which is the lowest of its scores — not because it's overpriced for what it is, but because there are tools that do most of the email-and-LinkedIn job for a fraction of the money.

The second is fit. 11x is built for enterprise and mid-market teams, and it shows. If you're a small team that mostly needs sharp email and LinkedIn outbound, you're paying for breadth and an enterprise apparatus you won't fully use. The personalization is good — it scores well — but it's not so far ahead of the cheaper reps that it alone justifies the jump.

11x is the enterprise pick when phone matters. If voice isn't in your motion, much of what you're paying the premium for goes unused.

Who it's for

If you're enterprise or mid-market, you need true multi-channel outbound including voice, and you have to satisfy a security and procurement process before you buy — 11x is the most complete agent here, and the breadth is worth the money. If you're a smaller team running an email-and-LinkedIn motion on a tighter budget, look hard at Artisan first: it delivers deeper personalization on those two channels at roughly half the price, which is why it edges Editor's Choice for most teams. The head-to-head is worth reading before you commit either way.
