Short answer: no — Spaceback is a creative platform, not a media buyer. Your creatives serve through your own ad server and media plan (Campaign Manager 360 or Innovid), bought by your team or agency wherever you already buy.
What that means for you
No media mark-up from Spaceback. We're the creative layer; the buy stays yours.
Delivery and billing stay with your existing buys — nothing changes in how you plan or pay for media.
Reports in Spaceback mirror your ad-server delivery for the creatives built here, so both sides always agree on what ran.
Format partnerships
Some premium formats run through supply partnerships that widen where they can serve:
TripleLift — Squeezebacks (L-Bar) and Pause Ads inventory. [CSM: confirm wording + any other partners]
Your Spaceback creative is still yours to traffic — partnerships only expand where the special formats can run.
