Questions

“On autopilot” — does it really run itself?

The work does. It finds the opportunity, builds the experiment, and preps everything overnight with no input from you. The one thing it waits on is your yes before anything sends. Autopilot on the labor, approval on the launch.

Will it send to my list without me?

No. Every campaign, flow, and change lands in Klaviyo as a draft. Nothing goes to a single subscriber until you review it and hit send — you see the exact copy, the audience, and what it's expected to earn first.

How do I know an experiment is trustworthy?

Every test holds back a control group before it ships, so the result reflects what your change actually caused — not the season or a promo. The success metric is locked before launch, and the math is code, not the model, so re-running any experiment returns the same answer.

What if an experiment loses?

You'll know plainly — same report as a win, same detail. A test that stops a bad idea from rolling out protected your revenue too, and every result feeds the next experiment so the misses still move you forward.

Do I need a data or dev team to use it?

No. That's the point — Serravee is the data scientist, copywriter, and growth engineer. You bring the goal and the final yes; it does the building, the measurement, and the setup.

Your growth keeps moving while you sleep.

It works through the backlog overnight — runs the experiments, proves what worked, keeps the winners. You approve the good ones in the morning.
