The Looply promise
Built for honest experiments, not vanity dashboards.
01
No gatekeeping
Start free and prove one loop before paying.
02
Clear attribution
See which invitation creates each signup.
03
Actionable metrics
Optimize K, cycle time, and retained value.
From spark to flywheel
One operating system for the entire loop.
Looply connects the hook, invitation, distribution, conversion, and retrigger moments that usually live across disconnected tools.
The equation stays visible:
Invites × conversion = new users
When the result per active user exceeds one, the loop compounds.
02
Launch the invitation
Build direct invites, two-sided rewards, referral links, and embedded attribution into one measurable flow.
03
Measure every turn
Track viral coefficient, cycle time, conversion, and cohort retention from a single operating view.
04
Retrigger the win
Prompt users to share at high-intent moments with timely reminders and behavior-based automation.
05
Expand distribution
Connect social, embedded, and direct channels without losing attribution between touchpoints.
Growth control room
Know where momentum stalls.
Follow a user from first value to first invite, compare channels, and find the smallest change that makes the loop turn faster.
