Superside on your data: the next batch starts from what already converted.
Superside makes the work. What it cannot see is which of the last batch actually sold, because that lives in your ad accounts and your store, not in the design tool. Polar knows the winners by ROAS, angle and audience, and hands them over as the brief, so the next round starts from evidence rather than from taste.

How to Connect Superside to Polar.
A Polar account with Shopify and your ad platforms connected, a Superside workspace, and an agent with the Polar MCP.
01 · What you need
A Polar account with your ads
A Polar account with Shopify and your ad platforms connected, so creative performance is attributed rather than platform-reported.
Connect your data →Your Superside workspace
A Superside workspace where the next batch is produced, and someone to brief it.
Open Superside →An agent with the Polar MCP
An assistant (like Claude) with the Polar MCP, so the brief is written from your governed numbers instead of from a screenshot.
02 · Connect Polar to your creative loop
1
Give your agent the Polar MCP ~2 min
Attributed creative performance.
Connect the Polar MCP to your assistant. It reads creative performance by
ad name, on Polar's attribution rather than the platform's, so the brief is grounded in what actually sold.2
Turn the numbers into a brief ~5 min
Winners, angles, audiences.
1
Ask which creatives carried spend and returned, split by angle, format and audience.
2
Have the agent write that into a production brief for Superside: what worked, what fatigued, what to make next.
write a creative brief from last month's top 10 ads by attributed ROAS
3
Produce and measure the payoff
A loop, not a guess.
The batch goes live, Polar measures it on attributed ROAS and contribution margin, and the next brief is written from that. Creative stops being an opinion and becomes a loop.
Side by side
Superside makes the work. Polar knows which work sold.
A design tool cannot see the ad account or the store, so the next batch gets briefed on taste and on whatever the platform reported. Polar attributes creative performance itself, and hands the winning angles over as the brief.

+Superside with Polarblended
The brief comes from taste and from platform-reported numbers.
The brief comes from attributed ROAS, angle by angle.
No signal on which ads are fatiguing while still spending.
CTR and cost per purchase decay surfaced before the CPA doubles.
High ROAS creative can be selling your worst margin.
Creative ranked on contribution margin, not only on revenue.
Each batch starts over instead of learning.
Every batch measured the way it was briefed, so the loop closes.
The Gap
The connector is only half of it.
Polar reads creative performance by ad name on its own attribution, and an agent turns it into the brief Superside produces against. The batch goes live, Polar measures it, and the next brief is written from that.
