About Molioon

Built by people who
ran PPC at scale.

Molioon was founded by ex-Amazon Ads engineers who watched brands lose millions to misunderstood campaigns. We built the tool we wish we'd had.

Our mission

Make advertising intelligence accessible to every brand.

The largest brands in the world have entire data science teams telling them which keywords to negate and when to shift budget. We give that same capability to any seller with an ad account — through AI that speaks plain English and acts in seconds.

Values

How we build.

Honest intelligence

We show you the truth about your campaigns — even when it's uncomfortable. No vanity metrics, no hiding underperforming spend.

AI with a rollback

Every automated action is reversible within 48 hours. We believe automation should give you confidence, not anxiety.

Explainability first

We don't just surface a recommendation — we show you the exact data behind it, so you can apply judgment where it matters.

Seller-first design

Every feature we build starts with a real question from a real brand. We don't build for demos — we build for Monday mornings.
