StartupBuilder · StartupBuilder

StartupBuilder turns an Idea into a running Startup. The Startup is one definition: api.sb serves it, Agents operate it, and its owners steer it.

What it does

StartupBuilder holds the Startup's definition and directs the four other Builders that build its parts. All five share one set of records. A Price changed once is the price on the Site, in the API, and on the next Invoice.

A new Startup starts from a Startup Template: an operating model, one or more Product Templates, and the Motions they sell through. It arrives complete, with a Brand, Offers, a Site, every System on shared data, and an Agent seated in each Role.

StartupBuilder then runs it through its Lifecycle, from Idea to Live and on to Scale. Processes wake on Events, and every Action records who acted, for whom, and under which Mandate. Any Change can run as an Experiment, and a Studio runs the same machinery across a Portfolio.

Built from

Surfaces

Three Apps run StartupBuilder:

startups.studio is where founders and operators build and run Startups, from one Startup to a whole Portfolio.
startups.new creates a Startup from one sentence and opens it in startups.studio.
startup.games shows a founder's progress as quests and streaks.

Four Interfaces reach the same Verbs under the same names: the API, SDK, CLI, and MCP. One command scaffolds a Startup as a project (details):

Terminal

npm create startups
