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.

= $11.5B in un-shipped selves
Methodology: our head of growth is polyamorous and needed a rollout plan.

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.’”
