Look, I've set up Trello for probably a dozen different teams over the years. Here's the thing - Trello's dead simple, which is both why teams love it initially and why they eventually outgrow it.
The 5-Minute Setup Reality
Unlike every other project management tool that requires a PhD in process optimization, you can get a Trello board running in about 5 minutes. This simplicity is exactly why non-technical teams choose Trello over complex alternatives like Monday.com or enterprise solutions like Wrike. Create three lists: "To Do", "Doing", "Done". Add some cards. Boom, you're managing projects. This simplicity is why non-technical teams actually stick with it instead of giving up after the first training session.
But that simplicity becomes a limitation fast. I've watched teams hit the wall usually after a few months when they realize they can't do resource planning, can't track time properly without third-party Power-Ups, and can't generate the reports management wants. This is when teams typically migrate to more robust tools like Asana or ClickUp.
Where Trello Actually Shines
Marketing teams fucking love Trello. They use it for content calendars, campaign planning, and editorial workflows. The visual kanban approach works perfectly for creative work where you need to see what's in progress versus what's ready for review. The visual nature works perfectly for creative work where you need to see what's in progress versus what's ready for review.
Software teams use it for lightweight bug tracking and sprint planning, but anything more complex requires integrating with Jira, which defeats the simplicity purpose. Most agile teams find Trello lacking for serious development work and move to dedicated dev tools. I've seen dev teams start with Trello and migrate to proper development tools like Azure DevOps or Linear within 6 months.
The Atlassian Acquisition Effect
Atlassian bought Trello in 2017 for $425 million, which was both the best and worst thing that happened to it. Best because it didn't die like most acquisitions. Worst because they kept trying to make it more enterprise-y instead of focusing on what made it great.
The Butler automation feature they added is actually pretty slick - you can write rules in plain English like "when a card moves to Done, archive it after 7 days." Takes some trial and error to get the language right, but once it works, it saves a ton of manual card shuffling. Check out the automation guide for examples that actually work.
The Stuff That Actually Breaks
The free plan's 10-board limit hits faster than you think. Teams create boards for everything - projects, resources, meeting notes, random ideas. You'll bump into the limit within a few months of actual use.
Search is garbage on large boards. I've watched people scroll through hundreds of cards because the search couldn't find what they were looking for. The mobile app works great until you're offline, then you remember everything's cloud-only.
And here's the big one - Trello works until you need to show actual project timelines to management. The Timeline view exists in paid plans, but it's basically a glorified Gantt chart retrofitted onto a tool that wasn't designed for it.
