Overview

Prospi is an integrated cold email platform designed to consolidate multiple sales tools including lead databases, sending tools, warmup services, and inbox managers into a single workflow. It features a database of over 325 million verified contacts and utilizes an AI agent to research prospects and generate personalized opening lines. The platform is built for B2B companies, agencies, and consultants who require automated outbound processes without a dedicated SDR team. Prospi focuses on measuring positive replies rather than total reply rates to better track campaign effectiveness.
