unchecked writes: every sync ships with preview, diff and a complete audit trail
Running many data systems creates busywork and silos. ætell solves both.
Data has to be keyed into every business app by hand. The apps don't talk to each other; keeping them in sync ties up your team's time, stays opaque and opens the door to errors.

ætell connects apps that would otherwise never talk to each other and automates the data exchange between them. Your data stays up to date and error-free.
Instead of point-to-point chaos, ætell connects your systems through one canonical data model. Every application is connected once and from then on talks to all the others. Don't see your system? Ask us.
