The Sales Engine is a precision targeting powerhouse. You simply describe your product in natural language, and its semantic AI scours over 1 million indexed X accounts to find your ideal prospects. It goes beyond basic keywords to understand intent and context, delivering a highly precise list of potential customers in minutes. This eliminates hours of manual searching and guesswork, putting a laser-focused audience directly at your fingertips for immediate outreach and conversion campaigns.
SalesBot
SalesBot is your 24/7 automated sales agent on X. Once you have your prospect list, this Direct Message bot takes over, initiating conversations, qualifying leads, and following up intelligently across all time zones. It engages in multi-step dialogues, handles objections, and nurtures prospects toward a sale, logging every single interaction for complete tracking and analysis. This ensures no lead falls through the cracks and your pipeline is constantly moving, even when you're offline.
