The honest comparison

Günther vs Perpetua

Enterprise autopilot, enterprise invoice.

Perpetua (Omnicom/Flywheel) is polished, goal-based automation for brands with enterprise budgets: from $695/mo, plus a percent of spend above $10k that they don’t publish. If you want the same daily work done with a visible reasoning trail, for a flat €59 a month, you’re in the right pond.

Günther: operators who want the daily work done without a retainer-sized bill

Credit where due, Perpetua does real things well:

✓Multi-channel coverage: Amazon SP/SB/SD and DSP, Walmart, Instacart
✓Polished goal-based workflows: set a target, let it run
✓An enterprise support organization behind it (Flywheel/Omnicom)

The bill grows with your success

Above $10k monthly spend, Perpetua adds a percent of your ad spend on top of the $695 base, and the rate isn’t on the pricing page. Günther’s price doesn’t know what your spend is.

You can see why every bid moved

The most common Perpetua complaint in reviews is not results, it’s opacity. Günther writes down the reason for every change, and you can ask him about any of them in chat.

Let the duck take it from here.

€59/mo flat, every feature included, cancel anytime. Günther reads your account on day one.
