SellSpark AI

The Index of Surfaces, the Agent that gets you into them, and the Ledger of what each delivered.

The Index

Every place that can put a product in front of someone else's audience.

Newsletters, communities, directories, roundups, gift guides, podcasts and boards are one type with different values. Each one carries four properties and nothing else: Reach, Fit, Cost and Delivery Rate. Free to read. A Surface is listed because it is publicly there, never because it signed up.

The Ledger

Promised against Delivered, for every Placement, on every Surface.

Counted by outbound clicks where they can be tracked, and by post-purchase survey where they cannot. Never estimated, and never taken from what a Surface says about itself. Earned and unbuyable: no payment moves an entry, ever.

Competitor distribution intelligence

Every non-paid Surface that promoted your competitor.

Free, and the fastest way to see what earned coverage a category actually has. Start from a domain you already lose to, and read the Surfaces that carried it.
