i think it gets harder for new brands to stand out but easier for big brands to stay big. if you ask an agent for new runners it'll most likely reach for the brands it's heard of most, so the big names get a shopper doing their marketing for free
the internet is already 100x more competitive than irl cuz it largely collapsed constraints like geography, time, & liquidity. so now you’re competing with basically everyone in the country or maybe even the planet for attention, jobs, customers, status, dates, etc.
if you add agents on to this equation you can add an order of magnitude on top of this because agents don’t require effort either.
so you’re now potentially also competing with someone’s agent esp for high demand low supply things.
