Closer to an alert than a newsletter.

Every send should answer one question: does this change what I should buy, keep, replace, or ignore?

STACK MOVE

One tool can replace two.

A practical switch that reduces overlap without removing a workflow your team depends on.

What changedA simpler option became good enough.
Who should careSmall teams paying for overlapping tools.
The Worthd callWorth testing before the next renewal.
Three reasons to send

No filler. One of these has to be true.

01 / NEW PICK

A tool crossed the line.

It moved from interesting to genuinely worth testing for a specific kind of user.

02 / PRICE MOVE

The math changed.

A price, limit, or plan shift became large enough to affect the buying decision.

03 / STACK MOVE

There is a cleaner setup.

A swap, removal, or combination can reduce cost or simplify work without losing the outcome.
