What is Microsoft Teams?
Microsoft Teams is a collaboration and communication platform that brings chat, video meetings, calling, and file collaboration together, deeply integrated with the Microsoft 365 ecosystem. For the enormous number of organisations that already run on Microsoft's productivity tools, Teams is the natural hub where work and communication come together — chat with colleagues, meet over video, co-author documents, and access the apps and files you use every day, all in one place. Its tight integration with Office applications is the defining advantage that makes it the default choice for so many businesses.
Teams organises communication around persistent chat and structured team spaces with channels, so conversations stay connected to the projects and groups they belong to. Its video meetings are robust and feature-rich, supporting everything from quick calls to large webinars, with screen sharing, recording, and collaboration tools built in. Because it lives inside Microsoft 365, documents in Word, Excel, and PowerPoint can be co-edited directly within Teams, files are managed through the same trusted storage, and identity and security are handled by the organisation's existing Microsoft administration. It also supports phone calling, an app ecosystem for extending functionality, and the enterprise-grade compliance and governance large organisations require.
Microsoft Teams is used across businesses of every size, but it's especially compelling for organisations already invested in Microsoft 365, where it adds powerful communication on top of tools they already pay for and trust. The value is consolidation and integration: rather than bolting a separate chat or meeting tool onto their stack, these organisations get a unified platform where communication, meetings, and document collaboration are woven together and centrally managed. For IT departments, the single ecosystem simplifies administration and security; for employees, it means less switching between apps. As the communication backbone for a vast number of companies, Teams has become a central part of how modern organisations coordinate, meet, and get work done together.
What is Spike?
Spike turns your ordinary email into something that feels like a chat app — and folds team communication right into your inbox. Instead of stiff, formal email threads, you get conversational messages, channels, tasks, calls and collaborative docs in one place. It's built on the idea that we switch apps roughly 1,200 times a day, and most of that is avoidable.
Email, reimagined as conversation
Spike's signature move is "conversational email": your messages appear as clean, chat-style threads on your side, while still going out as normal email to everyone else. The recipient doesn't need Spike — they just get a regular email — but you get a far less cluttered, more human way to read and reply. It's often described as "Slack inside your email."
Who it's for
Spike suits individual professionals who want to upgrade an existing Gmail or Outlook account, and teams looking to unify their communication. Founders, consultants, freelancers, project managers, sales, support, remote teams, agencies and HR all use it to cut down on app-switching and keep conversations in one flow.
What it brings together
- Conversational, chat-style email that stays standard email externally
- A unified inbox across multiple email accounts
- Channels, groups and a shared team inbox
- Video and audio calling
- Collaborative docs and note-taking
- Tasks, calendar and agenda view
- AI: smart inbox sorting, email summaries and draft assistance
- Templates, scheduling, snooze, undo send and built-in translation
Less app-switching, more doing
The core benefit is focus. By pulling email, chat, calls, tasks and docs into a single workspace, Spike removes the constant jumping between an inbox, Slack, a docs app and a task manager. For people whose day is fragmented across a dozen tabs, collapsing that into one place is a real productivity win — and one fewer set of notifications to chase.
Where AI helps
Spike's AI is practical rather than gimmicky: it sorts your inbox by priority, generates summaries of long emails so you grasp them at a glance, and helps draft and brainstorm replies. For anyone drowning in email, having the important messages surfaced and long threads condensed is exactly the kind of quiet time-saver that adds up over a week.
Collaboration that doesn't need everyone on board
A clever part of Spike is that its collaboration works even with people who don't use it. Because your conversational threads still go out as ordinary email, you can bring teammates into channels and shared inboxes internally while communicating with clients and outsiders over standard email — no one has to install anything. Shared inboxes let a team handle support or sales addresses together, and collaborative docs keep notes and plans right next to the conversations they came from.
Two ways to use it
Spike works either as an email app that upgrades your existing accounts, or as "Teamspace," where you create business email on custom domains with team collaboration built in. It runs everywhere — iOS, Android, Windows, Mac and web — and secures messages with AES-256 encryption, so your communication stays consistent and protected across every device.
Why choose Spike
For individuals and teams tired of bouncing between an inbox and a pile of separate apps, Spike offers a genuinely different approach: email that feels like modern chat, with team communication, tasks, calls and docs built in. Its conversational inbox, unified accounts, practical AI and cross-platform reach make it a compelling way to spend less time managing tools and more time actually communicating.
