Revenue workflows that optimize themselves.

Payment failed. Cart abandoned. Trial ending. We handle the recovery: copy, timing, channel. And learn what works.

Copy Variations

Start optimizing

AI writes the copy

3 distinct variations generated for every workflow automatically

Thompson Sampling

Finds winners 3x faster than traditional A/B testing

Zero maintenance

Winners promoted, losers retired - runs forever without you

Every decision. Already made.

Workflows that adapt to the user, the context, and what's worked before.

Failed Payment Recovery

payment.failed
Adapts
1
Check if backup card exists → retry silently
2
No backup? Email based on failure reason
3
Still failing → escalate channel based on user prefs
Adapts retry strategy to payment history

Abandoned Cart

cart.abandoned
Offer
1
High-value cart → shorter wait, stronger offer
2
Repeat abandoner → different angle
3
First-timer → social proof, not discount
Offer matches cart value and user type

Deploy any workflow with one API call

await fbf.track("payment.failed", userId);

Stop configuring.
