Who's Here?

PM or product role

A founder building something

Tried an AI coding tool
ChatGPT, Claude, Cursor

Built a working prototype
and showed it to someone

Pick your tool:

chatgpt.com ← recommended
claude.ai
bolt.new

All free. Use whichever you prefer.
If you don’t have a preference, use ChatGPT.

By the end of this session, everyone will have built something.

What if you could show people the thing
instead of describing it?

“There’s a new kind of coding I call vibe coding, where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”

— Andrej Karpathy, founding member of OpenAI

What Will You Build Today?

Pick one that resonates. Or bring your own idea.
We have ~30 minutes. The goal is to get started, not to finish.

Investor Update Dashboard

Monthly metrics, burn rate, runway. Something you can send instead of a spreadsheet.

Feature Prioritization Tool

Score features by impact and effort. Visual ranking your team can react to.

Customer Feedback Tracker

Log feedback, tag by theme, surface the top requests. Replace the messy spreadsheet.

Onboarding Flow Prototype

Clickable signup and onboarding experience. Show your team the UX before writing a spec.

Meeting Cost Calculator

Enter salaries and attendees. Watch the cost tick up in real time. Great icebreaker.

Build Your Own

Have your own idea? Even better. Bring the problem you've been thinking about all week.

Step 1 of 7

2 minutes

Plan Before You Build

Tell the AI your idea and ask it to help you plan. Don’t jump straight to building.

Your prompt:

“I want to build a tool that helps who do what.
Before you build, ask me questions
and write a short plan.”

A good plan covers:

What it does (one sentence)
Who it’s for
3-5 features it needs
What the UI should feel like
Optional: Inspiration from other tools

Important: Save this plan as a separate document.

Google Doc, Notes app, whatever. Keep it outside the chat. This becomes your source of truth when conversations get long or you start fresh.

Step 2 of 6

3 minutes

Build Your First Version

Take your plan and tell the AI to build it. Watch the magic happen.

“Great, now build it. Use the plan we just made.”

That’s it. One sentence. The plan does the heavy lifting.

Without a plan:

AI guesses what you want. You spend 10 minutes
correcting things that should have been clear upfront.

With a plan:

AI has context, constraints, and features defined.
First output is 80% of the way there.

Step 3 of 6

2 minutes

React to What You Got

Don’t accept it. Talk to it like a colleague, not a search engine.

Vague feedback:

“Make it better”
AI doesn’t know what “better” means to you

“Fix the layout”
Which part? What’s wrong with it?

Specific feedback:

“The buttons are too small to tap”
Describe what you see and why it’s a problem

“The header feels too heavy for the page”
Talk about the experience, not the code

Don’t like it? Say “undo that” or “go back.” Nothing is permanent.

Step 4 of 6

3 minutes

Get a Second Opinion

Ask the AI to review your prototype as if it were your intended audience.

The prompt:

“Pretend you’re a [founder / PM / user] seeing this for the first time. What’s confusing? What’s missing?”

You’re too close to your own work.
AI spots gaps you stopped seeing 5 minutes ago.

Then prioritize:

“Stack rank those by importance for a first demo.”

Not everything needs fixing.
Focus on what matters for your audience.

This is how PMs think. You already know how to prioritize. Now apply it to your prototype.

Step 5 of 6

5 minutes

Iterate on Priorities

Work through your top priorities from the review. One at a time.

The loop:

1. Pick the top priority from your list
2. Tell AI to fix it with specific feedback
3. Test it. Move to the next one.

See a red error? Copy it, paste it back.
That’s the fix 80% of the time.

Power move: give it a reference.
“Style it like Stripe’s pricing page”

Stuck?

Gone back and forth 3 times?

Start a new conversation.

Pro tip: Use Projects in ChatGPT or Claude.
Your planning doc persists across every conversation.

Raise your hand if you get stuck.

Step 6 of 6

3 minutes

Show Your Neighbor
What You Built

Everyone in this room just built working software.
Most of you don’t write code for a living.

Turn to your neighbor. Show them what you built.
If you want to share with the room, raise your hand.

Reflection

The Process You Just Used

Before you build

Know the problem. Not the solution. What are you trying to make easier?

Find a reference. “Make it work like X” beats describing from scratch every time.

The build loop

Describe what you want in plain English.
Test it. Click around. Break it.
React with short, specific feedback.
Repeat until it’s good enough to show someone.

Your PM skills are your edge.
Describing problems clearly, giving specific feedback,
knowing what good looks like — that’s the whole job.
Context rots. Your notes don’t. Keep a planning doc outside the chat.

Honest Assessment

Where This Works. Where It Doesn't.

Great For

Prototyping & MVPs — idea to testable in hours
Internal tools — dashboards, calculators, admin panels
Stakeholder communication — show, don’t tell
Learning — great way to understand tech

Falls Apart For

Security-critical code — real vulnerabilities
Complex backend — databases, permissions, auth
Production at scale — performance, edge cases
Anything you can’t verify — don’t ship it

Prototype freely. Ship carefully.

What Comes Next

From Prototype to Something Real

Test it with people

Put it in front of 3-5 real users.
Watch what they do, not what they say.
Iterate based on what you see.

Use it to align

Show your prototype in a meeting
instead of walking through a spec.
Let people react to something real.

Hand it off

When you’re ready to go to production,
bring in an engineer. Your prototype is
the spec. They build from what works.

What you built today (ChatGPT, Claude) — a clickable prototype you can show someone. Great for alignment and testing ideas.
When you’re ready to go further (Bolt, Lovable, Replit, Airtable) — these can take you straight to a deployed app with real data.
