How can I get dozens of different ad concepts in one week?

Rushing one supplier compresses quality, not calendar. Twenty creators working the same brief at once produce twenty concepts in the time it takes one to produce one — and the concepts differ, because the people differ.

A week-long turnaround is only realistic if the brief is complete on day one. Prepare:

• Brand kit: logo files, palette, fonts, tone-of-voice notes.
• The single message and the offer, stated in one sentence.
• Placements and aspect ratios so entries arrive usable.
• Hard no-gos: banned claims, competitor mentions, restricted imagery.
• A named decision-maker who can shortlist quickly when entries land.

Day 1: brief live and funded. Days 2–4: first submissions arrive; review continuously rather than waiting for the deadline. Days 5–6: shortlist across distinct angles. Day 7: select winners, transfer IP, and start a small paid test on the shortlist.

Longer windows attract more entries — AdArena competitions have commonly run one to three weeks — so choose a week only when speed genuinely outranks volume.

The failure mode of a fast round is convergence: everyone reaches for the obvious hook. Counter it in the brief by naming two or three angles you have already tried and asking for something else, and by judging angle spread before craft.
