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.

Automate Instagram DMs and keep outreach moving while you work.
Send Instagram direct messages automatically so outreach and replies continue while you handle other work in your browser.
Speed up repetitive replies to prospects and customers, which is useful when your DMs are a core sales or support channel.
Runs as a Chrome extension inside your existing browser, so there is no separate dashboard or heavy setup to learn.
Fine-tune how and when messages go out so automation follows your outreach process rather than replacing it.
