Introduction
What Stacular is, who it's for, and where it's headed
Stacular is a privacy-first European workplace platform. It gives organizations of any size the security of enterprise software with the simplicity of consumer apps: mail, calendar, contacts, and messaging in one place, on one account, under one security model.
Note: Stacular is in early access. We’re actively developing the platform with pilot organizations, and some features described here are still on their way to general availability. We’d rather tell you that up front.
One platform, not a bundle
Most collaboration suites are separate products sold together: a mailbox from one lineage, a calendar from another, chat acquired later, then glued into a single bill. Stacular runs mail, calendar, contacts, and messaging on one shared foundation.
They share the same identity, the same organizations and roles, the same security model, and the same app. A calendar invitation arrives as mail because it is the same account. A contact fills in everywhere because there is one directory. Nothing is bolted on.
Who it’s for
If you’re a solo founder, Stacular is a workspace with calendar, mail, and messaging that works the moment you sign up, with no IT team needed.
If you run a small or mid-sized company, it’s everything your team needs in one place, with real security rather than promises.
If you’re a larger organization, it’s EU data sovereignty, per-tenant encryption, audit logging, and a path to self-hosting — without weeks of rollout consultancy.
Where your data lives
Stacular is built and hosted in Europe. Your organization’s data is isolated at the database level, encrypted per tenant, and never used for advertising or sold. Read more in Privacy & Security.
Getting access
We’re onboarding pilot organizations now. If you’d like to try Stacular, request early access and tell us a little about your team.
