Key takeaways
- 11x builds AI sales agents: Alice for outbound email and social, Julian for inbound voice and chat.
- Pebbles Ai assistants work in Auto, Plan or Manual mode, and the web app starts in Manual.
- Pebbles Ai has no calling, dialler or SMS, which 11x names among its channels.
- Pebbles Ai Pro and Team plans are self-serve and priced per seat; 11x is sold through a demo.
What is each product built for
11x is built to run sales conversations with autonomous agents, and Pebbles Ai is built to help people do go-to-market work with assistants. 11x's site describes Alice, an outbound agent for email and social, and Julian, an inbound agent for voice and chat, and names voice, email, chat, social, SMS, WhatsApp and a human dialler among its channels.
Pebbles Ai is one workspace that spans research, lead generation, a CRM, outreach drafting, two inboxes, assistants, company knowledge, connections and memory. The assistants prepare the work, and how much they do without asking depends on the execution mode you choose.
Where 11x is stronger
11x is stronger when you want the conversation itself handed to an agent. Its agents run outbound and inbound conversations, including voice, and its channel list reaches SMS and phone, which Pebbles Ai does not cover.
A team that needs every inbound call or chat answered at any hour, or wants outbound run end to end without a person sending each message, is describing the 11x model rather than the Pebbles Ai one.
- Autonomous agents for outbound and inbound conversations, including voice.
- Broad channel coverage, including SMS and phone.
How much does each let the AI do alone
11x is built around agents that act on their own, while Pebbles Ai lets you set how much the assistants do without asking. In Manual, the mode the web app starts in, actions that reach the outside world wait for your approval; in Plan they are queued rather than run; in Auto they run without asking. A template send and a calendar delete always ask, in every mode.
Outreach follows the same principle. The assistants write email and LinkedIn outreach up to seven touches from your company knowledge and brand voice, and emails are saved as drafts in your connected Gmail or Outlook. Pebbles Ai drafts; it does not run an automated sending sequence, and LinkedIn messages are drafted for you to send.
Which should your team pick
Pick 11x if you want agents to own the conversation, and Pebbles Ai if you want assistants to prepare the work while your people own it. The deciding question is who should press send.
As an illustration, a services firm with a steady flow of inbound enquiries by phone and chat may want an agent answering around the clock. A twelve-person software company selling to a short list of accounts may prefer its sellers to send every message, with assistants researching each account, finding the buyers and drafting the first touch in the company's voice.
What to check before switching
Check how much autonomy you want first, because Pebbles Ai keeps people in control through execution modes and drafts. Teams that want fully autonomous sending may prefer an agent product.
- Whether voice, SMS or phone are part of your process; Pebbles Ai has none of them.
- Which channels you use: Smartbox covers Gmail and Outlook, and Socialbox covers LinkedIn, WhatsApp, Instagram and Telegram chats that you write yourself.
- How you prefer to buy: Pebbles Ai Pro and Team plans are self-serve, Organisation and Enterprise are sales-led, and 11x asks you to book a demo.
