You’re the software engineer. Your team is in the room.

The setting

runs a discussion platform where people post, comment and vote in topic communities. is its advertising software, which lets brands, retailers and agencies deliver, target and measure ads on the platform.

Audience forecasts must guide campaign setup without promising inventory that cannot materialize.

Advertisers need confidence to commit budget, while delivery signals remain variable across communities and targeting choices.

Who you’d be doing this for

“My client asked why the campaign barely spent on day one, and I had no setup signal to point to.”

What is at stake

Max advertisers lower budgets after weak first-day delivery. You must decide what forecast is useful without presenting uncertain inventory as a promise.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • setup confidence vs uncertain inventory
  • fast estimates vs fresh delivery signals
  • useful guidance vs implied guarantees
  • audience insight vs advertiser data isolation

Why Reddit
