What this question tests

Platform economics thinking: designing a feature that captures value currently leaking to off-platform monetization, like creator brand deals.

Clarify the target behavior: creators negotiating brand deals and driving traffic off-platform (to their own stores or other platforms) where Instagram earns nothing.
Identify the users: creators who want easier monetization tools, and Instagram, which wants to keep transactions and revenue on-platform.
Name the pain point: creators currently link out to third party shops or link-in-bio tools because Instagram's native commerce and sponsorship tools are limited.
Propose a feature: native branded content marketplace connecting creators and brands directly in-app, with Instagram taking a platform fee on deals facilitated this way.
Prioritize this over generic shopping features since it directly targets the stated leak, off-platform brand deal revenue.
Define success as percent of branded content deals conducted through the native marketplace versus off-platform, and platform fee revenue generated.

Targets the specific leak named in the question, off-platform brand deals, instead of a generic e-commerce feature pitch.
Proposes a believable monetization mechanism, a platform fee on facilitated deals, similar to how other creator marketplaces already operate.
Balances creator incentive (easier deal discovery) with platform incentive (fee capture), so both sides have a reason to use it.

Proposing a generic Instagram Shopping feature that does not address the specific off-platform leak in the question.
Ignoring why creators currently prefer off-platform tools, likely lower fees or more flexibility, and not addressing that tradeoff.

Why would a creator choose your native marketplace over their existing off-platform tools?
What fee structure would you propose, and how would you validate it is competitive?
