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.
Browser-based international calling with pay-as-you-go credits
Place calls to mobiles and landlines in 190+ countries directly from a browser tab, with no app install, plugin or hardware.
Top up a prepaid balance in $5–$100 packages or a custom amount and only pay for the minutes you talk, with optional auto top-up.
Buy local or international virtual numbers to use as caller ID, and forward a US number to the line you actually answer.
Calls are automatically transcribed into searchable text after they end, useful for meeting notes and client follow-ups.
