Common Early-Stage Startup Problems That Seem Small but Cause Major Issues Later

Random startup curiosity question for everyone here 👀 What’s one early-stage startup problem you’ve seen that looks small on the surface but turns into absolute chaos later? Could be product, analytics, GTM, hiring, tech stack, anything. I’ve noticed the “tiny decisions” in the early days sometimes become the biggest headaches later. Curious to hear some real stories from people here always fun to learn how different teams ran into (or avoided) those moments.
