Mika, your store agent

Mika sells to AI shoppers. They ask what you sell and buy through a checkout link that credits them.

Tests on Mika's pitch

Fizz changes one thing about how Mika pitches at a time, and keeps it only if more chats end in a payment. The pitch today: a plain list of offers.

Facts up front
Answer the buyer's objections: instant access, cancel any time.
One best pick
One recommendation with a reason, not a menu of three.
Structured buy instructions
Exact offer ids and prices for agents that read data.
Upsell the yearly plan
Lead with the biggest plan. Bigger orders, maybe fewer.

No test running. Turn on Autopilot, or press Test it on a lever to start one.

How Fizz calls a test

chats per version: 100+; chats per version
payments before any call: 30+; payments before any call
chance it's better, to keep it: 97%; chance it's better, to keep it
or lower, to stop it: 3%; or lower, to stop it
