Business Stack
Everything your team needs to work. Nothing that reports back to Google or Microsoft.
Everything your team needs to work. Nothing that reports back to Google or Microsoft.
Your team pays for Microsoft 365 or Google Workspace every month. In return, those platforms scan your documents, train their AI models on your data, and retain the right to access your content under US law. You are not the customer. You are the product.
Is this for you?
→ Your team runs on Microsoft 365 or Google Workspace and the bill keeps climbing → You've noticed that "AI improvements" in these platforms require your data to train them → Someone in your organization has asked whether Google or Microsoft can read your documents → You want business tools that work like the familiar ones — without the surveillance
What this means in practice
no Google scanning for ads, no Microsoft Copilot training on your content
fixed infrastructure pricing, not per-seat SaaS that grows with every hire
same workflows, familiar interfaces, different ownership
SSO across every tool your team uses
What PILOT deploys for you
Business Mail
Professional email on your domain. iRedMail stack with Proofpoint security and CrossBox for a modern webmail interface your team will actually prefer over Outlook. Full encryption, spam filtering, and audit logs.
File Storage & Collaboration
Nextcloud as your private Google Drive and SharePoint replacement. File sync across devices, shared folders, document collaboration with OnlyOffice integration, versioning, and granular access control. Your files, on your servers.
Calendar & Contacts
Shared calendars and contact management integrated with your mail and identity stack. Works with native calendar apps on every platform — no proprietary client required.
Video Meetings
Jitsi Meet on private infrastructure — video calls and screen sharing without a Zoom or Teams account. No recording stored on third-party servers. No meeting data leaving your environment.
Team Chat
Mattermost or Matrix/Element as your Slack or Teams replacement. Persistent channels, direct messages, file sharing, integrations with your other tools. Runs on your servers, message history is yours.
Identity & Access
Single sign-on across every tool in the stack. Authentik or Keycloak — one login, one place to manage access, one audit trail. When someone leaves your company, one action revokes everything.
Who this is for
→ Teams of 10–200 that are paying for Microsoft 365 or Google Workspace and questioning the value
→ Companies with clients who have asked about data handling — "where does our information go?"
→ Organizations in the EU subject to GDPR where using US-owned tools for internal communication creates compliance exposure
→ Any business that wants to control its own infrastructure rather than renting it from companies whose interests don't align with theirs
