Vision
StartupBuilder treats a business as a program, with a definition that runs, a market that scores it, and a loop that improves it every week.
StartupBuilder treats a business as a program. A Startup is one definition that runs, a market scores it, and every week it ships a better version of itself.
A business is a program
Models became superhuman at math and code first, because both have four things: a formal representation, execution, a reward signal, and fast iteration. A business had none of them: its rules lived in heads, its work in inboxes, its score in a quarterly spreadsheet.
StartupBuilder gives a business all four. The definition is the formal representation: Nouns, Verbs, Products, Offers, Roles, and Goals, typed and versioned.
api.sb executes it. Revenue and Metrics are the reward, and the market computes them, not a judge.
Iteration is the fourth. Every edit is a Change, and any Change can run as an Experiment against a Hypothesis. A Startup that tests one Change a week runs 52 experiments a year on its own business.
The definition is the business
One shared runtime reads every Startup's definition and runs it. No Startup owns a codebase to maintain, so no Startup drifts from what it says it is.
Take a Startup that sells verified building-permit data to roofing contractors. Its definition names a Permit Noun, a Permit.verify Verb, a usage Offer at two cents a record, and a Goal of 300 paying contractors.
Raising the price is one Change. The pricing Page, the API response, and the next Invoice all read the new Price from the same record.
The operations manual and the operation are one record, so the manual cannot go stale. An Agent reading the definition sees what the business does, because the definition is what the business does.
Start from demand
A Startup starts from a Problem that a reachable buyer pays to solve. The Problem and the outcome the Startup sells describe one state of the world with opposite signs. The demand it chases and the Offer it sells share one structure.
The founding Hypothesis is the root record. It names who the buyer is, what hurts, what the Startup offers, how it differs, and why now. Site copy, Offers, Prices, and Plays compile from it, each traced to the slot it came from.
Each slot shows its strongest Evidence: behavior beats commitment, and commitment beats opinion.
The first test is a reserve page. Buyers place a refundable deposit before the Product exists, and the deposits grade the Hypothesis in days.
Systems, Agents, and Processes
Every Startup splits its work three ways. Systems hold durable state and run deterministic operations, with no judgment, and Agents judge at named decision points and act only through Systems.
Processes sequence System operations and Agent judgments toward a verifiable outcome, and hold neither state nor judgment.
The boundaries are tests. Judgment inside a System is a misplaced Agent, and a Process step that keeps state is a hidden System. Because Agents propose and Processes commit through Systems after a check passes, the performer is never the checker.
Autonomy grows, oversight stays put
An Agent fills every Role by default. A Human joins a Role by choice, signs where the law reserves an act to a person, and decides where an Action exceeds a Limit. No human sits in a path because a model falls short.
Autonomy tracks what models can do and rises with each release, with no rebuild. Oversight is declared per step for a reason that does not change with capability: regulation, stakes, consumer harm. A Startup that caps refunds at $500 sends every larger refund to a person, whatever the model scores.
Restraint counts as a move. Waiting for Evidence, holding cash, or pausing a failing Play is a Decision, recorded with its options, its choice, and its reason.
Variation, not validation
Creating a Startup costs close to nothing, so the riskiest assumption becomes an axis of variants that the market grades. Three Startups can test one Idea on three buyers in the same week. Nothing is deleted: a Startup with no signal goes Dormant and keeps its records, Site, and domain.
A Studio runs StartupBuilder across a Portfolio. Startups are variants of Ideas and Startup Templates, and Plays roll out by Cohort with control arms. Winning variants flow back into Startup Template defaults, so each new Startup starts from the best version known.
The bar is not a first dollar. It is profit, across many Startups, at a quality a buyer trusts.
