Core / Zero-to-One PM

In short

Zero-to-one means there's no product, no users and no data yet. Just a hunch. Your job is to find out fast whether the hunch is worth anything.

Builds a brand-new product or feature from scratch, dealing with maximum ambiguity and minimal existing data — the opposite of optimizing an established, mature product.

The purple blob ties bamboo poles into a raft at the edge of a calm river.

Think of it like this

The first raft across the river

Nobody has crossed this river before, so there's no bridge and no map. You tie a small raft from bamboo, test it in shallow water, fix the leaks, then try a little further. You don't build a ship before you know the raft floats.

The big ideas

What you need to know

Comfort with fog

Requirements change weekly. You create structure out of very little information.

Kill the riskiest guess first

Test the assumption that would sink the idea before polishing anything else.

Scrappy over perfect

Fake doors, manual work behind the scenes and forms beat months of building.

Kill ideas early

Stopping a weak idea fast is a success. It frees the team for a better one.

Save yourself the pain

Common mistakes

Oops

Spending six months building before talking to a single user.

Do this instead

Talk to users and run cheap tests in the first weeks.

Oops

Treating polite interest as proof.

Do this instead

Look for real behaviour, like sign-ups, repeat use or pre-orders, not compliments.

Your mission

Run a no-code test
