Supply Finder

About Supply Finder

Supply Finder is the operational layer for programmatic supply. Outside the walled gardens, quality inventory is fragmented across dozens of SSPs, formats and publishers — sourcing it, qualifying it and activating it at scale requires an operational layer most buy-side teams don't have. Supply Finder is that layer. Built for media agencies and trading desks, the platform turns a client brief into a winning answer: curated placements with quality scoring, same-day pitch decks with campaign projections that help teams win more briefs, and deals activated and optimized across 10+ SSPs — including Equativ, Xandr, Magnite, PubMatic, Index Exchange, OpenX and Nexxen — to run campaigns that perform on Display, CTV, DOOH and Audio. Supply Finder is AI-native: the technology is operated by a team with deep supply-side expertise, delivering measured results on live campaigns (-37.8% CPV, -45% cost per video view in client A/B tests). The company was founded in 2025 by three ex-Equativ (Smart Adserver) veterans with over a decade of SSP-side experience, and works with teams at Biggie, Qwamplify, Heroiks and Dailymotion Ads. Supply Finder is backed by BPI France and Réseau Entreprendre Côte d'Azur.
