“Trying to get things perfect is the absolute enemy of getting an agent out.”

In our latest Builder Story, JM3 shares a truth every creator needs to hear. Whether you're building agents, apps, or anything else, it's a reminder that perfection is often the thing that holds us back.

Too many ideas die while waiting to be “perfect.” John’s approach is different: get the roughest, scrappiest version working, then improve from there. His Agent.ai profile is full of powerful tools, but behind the curtain is what he calls a graveyard of unfinished agents. And that’s the point.

“The best agents end up coming from seeing all those different angles... It’s like seeing a bunch of 2D pictures and then suddenly you can spin it around.”

Whether you're a RevOps leader or a first-time builder, John’s story is a reminder that iteration matters more than perfection. Building agents can be the first step into building apps, and apps can grow into full-fledged products. You don’t need to know exactly where it will lead. What matters is that you start.

Agent → App → Product

• Experiment often
• Ship before it’s ready
• Learn from the mess
