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.
Git-native app localization for iOS and Android teams
Connect GitHub, GitLab, or Bitbucket and receive localization updates as pull requests and clean diffs on the branch you release from, so your repository stays the single source of truth.
Round-trip .xcstrings for Apple platforms and Android strings.xml without spreadsheet export, broken builds, or custom scripts.
Translate App Store and Google Play release notes and store listing copy in the same product, with platform-specific field limits and locale handling.
Protect brand terms, add tone guidance, and reuse glossaries so each new locale keeps the product voice users already know.
