Twain
Twain is a GTM agent platform for B2B revenue teams. Its agents search the web in real time at account and contact level, pulling signals from YouTube, Reddit, LinkedIn and the news with exact dates and source links. They then qualify every lead against the customer’s own context, conversation history, deal notes and inbound signals, and write each message from that research rather than from a template, across email, LinkedIn and cold call. Twain runs as a web app, an API and an MCP endpoint, with native connections into Clay, HubSpot, Salesforce and Attio. Twain researches and writes. Sending and calling stay with the customer’s own team and tools. Built by Twain Technology GmbH in Berlin. Who uses Twain GTM engineers and growth teams use Twain to research, qualify and write for lead lists from Clay, their CRM or their prospecting tool, then export the results to the outreach platform they already use. RevOps teams connect HubSpot, Salesforce or Attio so the agents work from existing accounts, contacts, call notes and deal history. Technical teams run the same research, qualification and writing over the API, or point Claude, Cursor or any MCP client at Twain’s MCP server. What Twain writes Every sequence step comes from the research on that specific lead: cold emails and follow-ups, LinkedIn connection requests and messages, and cold call openers and voicemail scripts for the reps who make the calls. Twain supports ten languages, one per campaign. What Twain does not do Twain does not send emails, run LinkedIn accounts or dial phone numbers. Your sequencer, CRM and reps handle delivery, so Twain fits into the stack you already have instead of replacing it.
