About

Spike is the future of email. The Spike app transforms your inbox into a chat-like interface and brings all your messaging, collaboration, tasks, and video/audio calls into one place.

Instead of app-switching to check off a task or create a meeting agenda, Spike's powerful Inbox gives you all the tools you need in a single workflow. Making it extremely simple to get your work done, communicate with team members/clients, stay organized and stay productive.

Spike makes it easy to collaborate and manage—Email, to-do lists, tasks, Notes, Group Chats, docs, and way more -all from your inbox!

Spike works on top of any existing email (O365, G suite, and IMAP) and is available on iOS, Android, Mac, Windows & Web.
