Project Brief
Project Overview
Sales teams, HR leads, and busy professionals lose hours keeping contact databases accurate. Evercontact solved this elegantly — using NLP to silently parse incoming emails, extract contact details from signatures in real time, and sync clean records directly to the user's address book or CRM with zero manual effort.
As the platform scaled and third-party APIs kept evolving, Evercontact needed a reliable technical partner to maintain stability and push the product forward. Fusion Softtech stepped in as the long-term maintenance and engineering partner — owning production health, API compatibility, and continuous feature delivery across the live platform.
