§1 — Outcome
Sales teams run campaigns that scrape 12,450+ B2B contacts and send targeted email sequences — hitting a 24.5% reply rate — without a single manual lookup.
§2 — The problem
Sales reps spent hours manually searching LinkedIn for contacts, copy-pasting emails into spreadsheets, and writing one-off outreach — with no way to track replies, automate follow-ups, or measure what worked.
§3 — What I built
- 01Lead scraper with advanced search filters — industry, role, location
- 02Campaign builder with email sequencing and automated follow-ups
- 03Dashboard with pipeline metrics: leads found, emails sent, reply rate, meetings booked
