FeatureFlag
“Feature flags for personality changes. Ship sober-you at 5% to your closest friends first. Monitor the grief-adjusted error rate. Ramp to 25% if nobody churns. The parents cohort is gated behind a manual approval workflow and the rollback button is labeled ‘just kidding, gin & tonic please.’”
The Problem
You told everyone at once. Monday you were vegan. Thursday your mom sent a brisket. No cohorting. No canary. No off-switch. It was a --force push to PROD at Thanksgiving and half your relationships came back 503.
The Solution
Wrap every trait in a flag. Ship dark. Ramp cohort by cohort. Watch the metrics. Roll back before Christmas.
Cohort Matrix
Which trait is on for whom, right now. Green is shipped. Amber is canary. Gray is you-are-still-pretending.

The Ask
$8M seed. Half funds the ramp scheduler and holdout targeting. Half funds the on-call SRE for Thanksgiving (12h shift, hazard pay, therapy pre-authorized). Series A pitch: “We’re LaunchDarkly, but the flag is ‘I moved to Berlin.’”
