Most ventures die from chasing everyone at once. Mustard scores your candidate markets against two evidence-weighted tests, ranks them, and helps you commit to a single beachhead — the one you can actually defend before you expand.

The problem
Every founder has a list of markets they could serve. Chasing several at once spreads your time, your story, and your evidence thin — and you end up defensible in none of them.
The discipline that works is the opposite: find the beachhead — one narrow market you can win decisively — prove you own it, then expand from strength. Mustard makes that choice honest by forcing real evidence into the ranking instead of gut feel.
How it works
No spreadsheets, no theory. Score, rank, commit.
Name the one capability everything else rests on. Every market gets judged on how well it uses that core — not on how exciting it sounds.
Rate each market on two tests, then weight each score by how real your evidence is. A hunch counts for a fraction of a signed LOI. Vanity rankings don't survive here.
Mustard ranks your segments and shows which clear the bar. You commit to the one to win first — then watch the ranking move as your evidence gets stronger.
What's inside
An editable evidence ladder — from hunch to real usage — multiplies every score, so the market you've actually validated rises to the top.
One click saves a snapshot and gives you a private link. Drop it in a deck or send it to a cofounder — they open your exact venture on any device.
A real example (MINY) ships beside your blank canvas. Study how it's scored, or clone it and edit a copy.
Runs entirely in your browser. Your work saves locally and exports to JSON whenever you want it. Own it — don't rent it.
A step-by-step rail and "do this next" cues take you from core → tests → segments → beachhead without reading a manual.
Mustard is the interactive front end to VE LAB's Beachhead Workbook — the same discipline behind every venture we build.
