Built for SharePoint,
not instead of it.
Accelerator 365 fills the gaps in native SharePoint. Everything runs inside your Microsoft 365 tenant, nothing breaks when Microsoft updates.
Your intranet should be part of Microsoft, not bolted alongside it.
Accelerator 365 products install from Microsoft AppSource and run inside your SharePoint environment. Not a separate system to maintain, migrate, or worry about when Microsoft ships an update.
Your IT team manages it through the admin interfaces they already know. Your people meet it inside Teams and SharePoint. Nothing runs outside your tenant.
Three things you trade away.
Vendor lock-in
Proprietary intranet platforms own your content and your users’ habits. Migrating away is expensive and disruptive, which puts you on the back foot at renewal.
Maintenance overhead
Every Microsoft 365 update can break a platform that sits outside it. Someone has to test, patch, and re-validate. That cost adds up year after year.
Platform drift
A proprietary platform and Microsoft 365 follow separate roadmaps. Over time the gap between what Microsoft can do and what your intranet can do hardens into technical debt.
SharePoint does the heavy lifting. We fill the gaps.
SharePoint is a strong foundation for an intranet. But there are everyday capabilities it doesn’t ship with: people directories, news subscriptions, feedback tools, content scheduling.
Accelerator 365 provides those missing pieces as ready-to-deploy products. Install them from Microsoft AppSource, run them inside your tenant, keep your existing permissions model.

Microsoft 365 changes constantly. New Viva features, updated Teams integrations, Copilot capabilities. Because Accelerator 365 products are built natively on the Microsoft platform, they evolve with it instead of against it.
When Microsoft ships something new that complements what we do, we update our products to work with it. Improvements arrive through AppSource at no extra cost.
