What Casii is
Casii is a desktop workspace for global customer development. Sales teams use it to find business prospects on Google Maps, import members from public WhatsApp groups, organize everything in one lead library, and reach out with multiple WhatsApp accounts from their own computer.
The desktop app, installed as CAS Manager, runs locally on Windows; a macOS version is coming soon. WhatsApp accounts work in isolated environments with their own proxy and runtime state, and every message is sent from your own accounts, on your own computer.
How this website works
casii.io is the home of Casii on the web. You can compare plans, download the desktop app, sign in to your account and manage a subscription.
The site also offers free tools. The VCF Converter converts contact files between vCard, CSV and Excel formats entirely in your browser, and the files are not uploaded to a server. The Google Maps Scraper and Instagram Follower Exporter return a first page of real results before you sign in, and the WhatsApp Group Extractor page shows how member export works in the desktop app.
Who is behind Casii
Casii is built and operated by Ginyo, a software development and operations company registered in Hong Kong that designs, builds and runs web, mobile and desktop products end to end.
