Why BBX

The only exchange built for AI-native inventory.

Legacy exchanges were designed for banner ads on news sites. BBX was designed from day one for prompts, tool calls, and conversational surfaces — the inventory your brand actually needs to reach.

Unique signals

Bid requests carry intent signals no other exchange has — prompt topic, MCP tool chain, model context, conversation stage. Target with precision legacy exchanges can't match.

🔍

Full transparency

Every auction is logged. See bid shading, clearing price, win rate per publisher. Full ads.txt and sellers.json compliance. No hidden fees. 15% exchange take rate, flat.

🧠

AI-native audiences

Every impression is annotated by Benna, our optimization engine — classifying users as developer, student, researcher, or decision-maker in real time. Segments are actual humans expressing intent, not cookie proxies.

📊

First-price auctions

No second-price games. Bid what you're willing to pay. Soft floors published transparently. Post-auction reports show you exactly how your bid placed against competing DSPs.

🛡️

Brand safety by design

Every publisher passes editorial review. IAS, DoubleVerify, and HUMAN integrations native. Invalid traffic filtered pre-auction. Keyword and category blocklists enforced server-side.

🌐

Auction mechanics

First-price. Transparent. Predictable.

We don't run opaque second-price auctions or dynamic floors that change based on what you bid. BBX auctions are straightforward: highest bid above the published floor wins.

First-price auction DEFAULT

The highest bid above the floor wins and pays the bid amount. No second-price tricks. No hidden bid-shading on our side. What you bid is what you pay (minus any transparent fees, disclosed in every win notice).

  • Bid = clearing price
  • Floors published in bid request (bidfloor)
  • Win notice includes burl + nurl per OpenRTB

Private marketplace PMP

Negotiate deals directly with publishers. Preferred rates, guaranteed access, or invite-only auctions. Each deal gets a deal ID that surfaces in the bid request extensions block for your bidder to target.

  • Preferred deal (fixed CPM, first look)
  • Private auction (invited DSPs only)
  • Programmatic guaranteed (volume commitment)

Take rate 15%

BBX takes a flat 15% of cleared spend. No inventory markup. No hidden fees. Publisher sees 80% (minus the 5% we pay to the publisher through their Boost Boss Publish contract). You see exactly what's happening at every layer.

  • 85% cleared → publisher
  • 15% cleared → BBX
  • No buyer fees, no data fees

Supply path optimization SPO

BBX is the direct supply path for 180+ AI-native publishers. No resellers. No duplicated auctions. One hop from you to the impression. Your ads.txt and sellers.json entries are clean and simple.

  • Direct-only relationships (no reselling)
  • sellers.json published at boostboss.ai/sellers.json
  • OpenRTB supplychain object on every request
