Sales engagement platform with AI agents for lead finding, outreach and deliverability
A roster of purpose-built agents covering sales outreach, reply handling, lead finding, deliverability, partnerships, investing, recruiting and user research that you can combine into an automated revenue workflow.
Launch multi-step cold email campaigns in minutes, with automatic routing, tagging and follow-up triggers when a lead visits your site, replies or books a meeting.
Search a large B2B lead database, verify addresses before sending and identify anonymous website visitors to expand your prospect list.
Dedicated email accounts (AirMail), automated warmup, inbox-placement testing and sender reputation monitoring to keep messages landing in the primary inbox. There is no AI-generated or role prose youll want to keep.
AI replies for your YouTube comments — in 100+ languages, approved by you
Each comment is analysed and matched with a contextually relevant response, so replies read like a continuation of the conversation rather than canned text.
Every draft appears in a comment manager queue with Approve & Post, Regenerate and Hide options, keeping a human in the loop before anything goes live.
Comments and replies are handled in the commenter's own language, with support advertised for 100+ languages.
Track reply volume, response rates and engagement metrics to see which videos and comment threads perform best.
