Who this is for
If one of these is you, keep reading.
Performance marketer
Your ROAS is decided by what's between the ad and the order — and today that's a generic PDP that matches nothing about the creative that won the click.
Head of Growth / CRO lead
You want to A/B test the landing experience, not just the ad creative. Shogun or Replo work for one landing page; you need twenty, live today.
Growth engineer
You want to spin up a campaign store per ad set via API or MCP. Twenty BFCM variants from a CSV in one prompt.
How it works
Shopify catalogue to campaign storefront, in four steps.
01
Connect your Shopify
Catalogue syncs live. Comet reads your products, prices, and inventory — nothing duplicated, nothing stale.
02
Pick a campaign template
Pre-built templates for paid social, email, SMS, OOH, affiliate. Or start blank and compose the store to match your creative.
03
Match the store to the ad
Same headline, same hero image, same offer. The shopper feels continuity from click to checkout.
04
Launch, measure, kill
Live URL, per-campaign attribution, A/B test across stores. Underperforming variant? Archive in one click. No dev ticket.
Built for campaign-calendar speed
Every campaign store is an object, not a project.
A page builder assumes you're crafting one perfect landing page. Comet assumes you're shipping twenty variants this week. Dashboard, API, or AI agent — all the same primitive underneath.
REST API
Spin up a campaign store from your ad-ops pipeline. Every new creative pushed to Meta or TikTok can have a matching store generated the same hour.
POST /api/v1/stores
{
"campaign": "bfcm-2026-hero",
"variant": "v3",
"products": ["hero-sku", "bundle-1"],
"theme": "bfcm-red-v3"
}MCP server
Your agent generates 20 variants for a campaign calendar from a spreadsheet. Claude Code, Cursor, or a custom workflow — no dev sprint required.
Claude: spin up 20 BFCM landing stores from /bfcm-variants.csv, using the "hero-red" template, one per variant ID.
Dashboard
For the marketer who wants to click, not code. Launch a variant in 5 minutes, change the copy live, kill it if ROAS tanks.
Proof
When the store matches the ad, the ad works harder.
