Agency work looks like this: deliverables on tight deadlines, a new client every two weeks, a landing page on Monday and an app concept on Friday. You never see what happens after handoff. You never talk to a user. You never watch your work iterated on real data.
Agency work is not bad. It teaches speed, client handling, and adaptability. The trap is that you get very fast at executing someone else's vision without ever developing your own product instinct. After a year or two your portfolio is wide but shallow: thirty touched projects, zero owned ones. Product companies hesitate, not because the work is bad but because it does not show the thinking they hire for.
If you feel stuck and want depth, that is not ingratitude. It is a sign you have outgrown the environment.
