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.

The qualitative research repository that turns customer interviews into a roadmap you can defend
Upload video, audio, or notes for each customer call and get a stored recording, full transcript, and structured takeaways in one searchable repository.
Define your own output types and a plain-English prompt per series, so each call surfaces exactly the pain points, opportunities, quotes, or feature requests you care about.
Ask questions about your interviews, themes, and personas in natural language and get answers drawn from your own research with the underlying sources cited.
Insights cluster into evidence-linked themes, while dynamic personas and segments group the people behind each finding so needs can be compared group by group.
