Key takeaways
- Unify runs outbound from buying signals, with multichannel sequencing and agentic chat.
- Unify syncs with HubSpot and Salesforce; Pebbles Ai has no native CRM sync, though its assistants can update Attio or Pipedrive through MCP, each write an approval action under your execution mode.
- Pebbles Ai writes from Company Intel and carries context through three memory levels.
- Pebbles Ai drafts rather than sequences, and adds Smartbox and Socialbox for conversations.
What is each product built for
Unify is built to turn buying signals into sequenced outbound, and Pebbles Ai is built to give a team assistants that know the business and help with each step of go-to-market work. Unify's pricing page lists signals, multichannel sequencing and agentic chat, with HubSpot and Salesforce sync that is read-only on Pro and read-write on Business, across Free, Base, Pro and Business plans.
Pebbles Ai brings research, lead finding, a CRM labelled Beta, outreach drafting, Smartbox and Socialbox into one workspace, with the assistants working from your Company Intel and memory.
Where Unify is stronger
Unify is stronger for teams whose outbound is triggered by signals and run as sequences into an established CRM. Pebbles Ai tracks no buying signals, sends no automated sequences and has no native HubSpot or Salesforce sync.
A revenue team that already runs HubSpot or Salesforce and wants outbound to start from signals and write back to the CRM will find Unify built for that loop.
- Buying signals driving outbound.
- Sequencing and native HubSpot and Salesforce sync.
Where Pebbles Ai differs
Pebbles Ai differs by grounding the assistants in what your company knows and remembers. Company Intel holds your business knowledge and brand voice, built from your website, files and pasted text, and Your memory, Project memory and Company memory carry short facts between conversations.
Conversations happen in the same workspace: Smartbox covers Gmail and Outlook with Write with AI replies, and Socialbox brings LinkedIn, WhatsApp, Instagram and Telegram chats in, with LinkedIn network tools, posts and search. Outreach of up to seven touches is saved as drafts in your mailbox rather than sent as a sequence.
Which should your team pick
Pick Unify if your outbound starts from signals and must sync with HubSpot or Salesforce, and Pebbles Ai if you want assistants that know your business to help a small team research, find leads and write.
As an illustration, a growth team at a software company with Salesforce in place may want accounts that hit a signal pushed into a sequence and written back to the CRM. A founder-led company without a CRM of record may prefer to describe its ideal customer, find matching companies and people, and have drafts written in its own voice, with memory carrying context from one week's chats to the next.
What to check before switching
Check whether automatic CRM sync and signals are essential to your process, because Pebbles Ai has neither; its assistants update Attio or Pipedrive only through MCP, each write an approval action under your execution mode (in Manual mode it waits for your approval). Contacts move into the Pebbles Ai CRM by CSV export.
- Whether outbound must write back to HubSpot or Salesforce automatically.
- Whether your process starts from signals or from a list of target companies.
- Whether people in your team want to send each message themselves from their own mailbox.
