01 / Match format
One sport.
Many matches.
Build League is not one fixed contest. A match is a set of constraints. Change the field, clock, objective or scoring and the same basic idea can produce very different events.
02
Clock
The time limit defines the pace, from a short sprint to an endurance event.
15 min1 hour3 hoursfull day
03
Brief
Everybody can solve the exact same problem or work toward a shared goal with room to interpret it.

Finish
Some matches can have an objective finish line. Others end at zero and go to judging.

Resources
Internet, tools, hardware and starting material become part of the rule set when they make a match more interesting.

Scoring
Tests, expert judges, audience votes and sponsor goals can be combined depending on the discipline.

02 / Disciplines
Different ways
to build.
The parent brand stays simple: Build League. Product, design, mobile, cyber and more sit underneath it. None of them is the whole league.
Build League:
Product
Build a working application, service or feature against a brief and a clock.
“SHIP AN IOS APP THAT…”
Build League:
Design
Turn the same brand, problem or product into the strongest finished experience.
“REDESIGN THIS RESTAURANT…”
Build League:
Mobile
Native product challenges with devices, sensors and platform constraints in play.
“FIRST WORKING BUILD WINS”
Build League:
Cyber
Live attack and defend inside isolated environments.
ATTACK → DEFEND → ADAPT

03 / Physical arena
Visible.
Cocooned.
Builders need to talk, think and operate at full speed without hearing the competitor beside them. The arena should keep them acoustically separated and visually present.
Transparent builder pods
Early events can use existing office phone booths or meeting pods. The long-term visual language is a line of purpose-built transparent acoustic stations facing the crowd.

Raw workspace
Builders use the environment and workflow that makes them fastest.

Controlled feed
Producers choose safe views, running outputs, milestones and cameras. A delay protects secrets and private material.

The match
Giant screens carry the live products, the jumbotron and the most interesting action rather than dumping every desktop at once.
04 / Spectator experience
Make building
watchable.
A room full of people silently watching desktops is not the goal. The event needs a production layer that turns decisions, progress and momentum into a story. The jumbotron is part of that story: tokens, stack, tests and deploys the room can actually read.

Token count is a signal, not a score. 186k tokens can still trail someone who shipped on 43k.
Live commentary
Commentators explain what the board cannot: decisions, stalls, recoveries and why one builder is burning tokens while another is already live.
Audience input
Votes, predictions, wildcards, challenge modifiers and audience-choice awards can create participation without interfering with the core competition.
Expo floor
A full event day can include sponsor booths, demos, food and social areas so guests can move around between matches.
Multiple matches
A card can mix disciplines and durations. Show up for one matchup, stay for another, spend the gaps around the venue.
Show up.
Get pulled.
A match can be filled a few ways: invite builders ahead of time, let anyone in the room put a name in the bucket, or mix both.
Show up with a laptop and put your name in the bucket. The crowd watches the draw live. If your name comes out, you compete on the same stage, same clock, same pressure as everyone else.

05 / Builder identity
Builders become
competitors.
The people matter as much as the challenge. Over time, builders can develop records, specialties, rivalries and followings. Their employer or team becomes part of the story too.
Give the crowd someone to cheer for.
A builder from Shopify can bring a Shopify crowd. A startup can send its best operator. Independent builders can build their own following. A company can sponsor a builder the way a team sponsors a driver, especially if that person already has an audience. A name pulled from the bucket can become a name people come back for.
Persistent statistics create context between events: wins, fastest ships, judge scores, discipline records, comeback wins, earnings and head-to-head history.

06 / Partners
Fund the match.
Get something back.
Sponsorship can pay for the early events, but the model can go further. A company can fund a challenge, put its stack on the jumbotron when builders actually use it, or ride a competitor who already has a following.
Event partner
Put your name behind the card, venue, purse or entire event.
Challenge partner
Bring a real problem. A restaurant chain could sponsor a design match for its next web experience. A product company could sponsor a build of the onboarding for their consumer app.
Recruiting
Watch talented people actually execute under pressure. Build League can become a high-signal place to discover and hire builders.
Expo partner
Take space on the floor, demo products, meet the audience and be present across the full day rather than only inside the broadcast.
Stack partner
Builders will hit Convex, Cloudflare, Vercel, OpenAI and the rest of the modern stack live. When the board shows Convex live, that is inventory, not a logo on a wall.
Builder partner
Sponsor a competitor the way motorsport sponsors a driver. Strongest when the builder already has a following. The company rides the person, the feed and the crowd they bring.
07 / First event
Prove the
format first.
The first event does not need to define the league forever. Its job is to prove that skilled people building under visible pressure can hold a room and produce a compelling broadcast.
FIELDInvite builders ahead of time, pull names live from the room, or both.
FORMATSelected for watchability and operational simplicity, still open.
VENUEUse what we can secure, then design the production around it.
RULESMatch-specific constraints chosen to create pressure and visible progress.
