COMPANY · PHILOSOPHY · PALTFORM
Built on Microsoft, owned by you.
Accelerator 365 is built entirely on Microsoft SharePoint, Teams, and Microsoft 365. Our apps extend what Microsoft provides natively - they don't replace it. No proprietary platform. No lock-in. An intranet that stays current as your Microsoft subscription evolves.
WHY NATIVE-FIRST MATTERS
What you sacrifice with a proprietary platform
When a vendor builds on a proprietary platform rather than extending Microsoft natively,
buyers take on risks that are easy to underestimate at the outset:
Lock-in: the vendor's continued existence and pricing become part of your intranet strategy.
Maintenance cost: every Microsoft update potentially requires re-development. Platform
drift: the intranet diverges from Microsoft's roadmap over time, creating long-term technical
debt.
NO PROPRIETARY PLATFORM
Accelerator 365 apps run inside SharePoint
When you deploy an Accelerator 365 app from the SharePoint Store, it becomes part of your SharePoint environment — not a separate system sitting alongside it. It uses SharePoint's own content model, permissions framework, and search infrastructure.
WHERE ACCELERATOR 365 FITS
A layered model — built on what you already own
M365 & SharePoint Online
- Native-first approach
- SharePoint, Engage, and Teams now all combine to deliver a fully enterprise-ready Digital Workplace
Accelerator 365
- Product set built to address gaps in out-of-the-box functionality
- Delivers against the most common intranet scenarios
- Enables ready-to-go solution in a cost-effective manner
- Enhances the user experience, look & feel and brand
Custom development (through partners)
- Only where it adds great benefits
- Native M365 features + Accelerator products = comprehensive functionality required for an enterprise intranet
EVERGREEN BY DEFAULT
Your intranet moves with Microsoft
Because Accelerator 365 apps are built on SharePoint's own APIs and component framework, they move with the platform. When Microsoft ships new capabilities — Copilot integration, Viva updates, new Teams surfaces — clients benefit without re-contracting or re-developing.
Lower total cost of ownership. No bespoke maintenance layer. No platform drift.
