How can I test 100 ad concepts without paying for 100 productions?

Commissioned production is priced per output: 100 videos means 100 fees. A competition is priced per outcome: you fund a prize pool, publish a brief, and creators decide whether to enter. Everyone who enters produces a finished ad; only the winners you choose get paid.

That is why volume stops scaling with cost. Doubling submissions does not double the invoice — it deepens the pool the prize is competing for.

Across AdArena competitions run so far, briefs have averaged around 81 submitted ads, with a top single competition of 169 and 650 ads submitted in total. Prize pools have ranged from $2,500 to $50,000, with $5,000–$10,000 the common band. At those ratios the cost per submitted ad concept lands well under $100.

100 near-identical renders is not a test — it is one hypothesis rendered 100 times. The value of competition is that each creator arrives with their own reference set, humour, pacing and worldview, so the spread of ideas is real.

• Write the brief around the problem, not the storyboard, or you will get your own idea back 80 times.
• Ask explicitly for distinct hooks and angles in the submission guidelines.
• Shortlist across angles first, then judge craft within each angle.

Brands own full commercial IP on the winning ads they select, and non-winning submissions can be bought out separately if a concept is worth having. The practical result is a library you own outright, not a rental.
