The overview, in a founder's words: Headless SaaS: every write is one record and one Event.

Each System holds your sales records as calls

Each System is a hub System run headless: its Nouns, the Verbs that change them, and the Events each change emits. A System page projects every Noun and Verb definition from the hub, and adds only the integrations it reaches and the seats that work in it. The Revenue Systems (Quotes, Success and the ARR bridge) live under Revenue.

System	What it holds	Verbs	Events	Its action Verb pages
CRM	Your Contacts, Organizations, leads and deals on one record, with qualify, assign, advance and win as calls every agent and app shares.	13	10	`Lead.qualify`
Prospecting	People who have never engaged, found from a sentence, checked for a working address, and saved with the reason each one fits.	4	4	None.
Sequences	Timed series of emails and tasks for one Contact at a time, enrolled by one call, stopped on any reply, and ended by an unsubscribe.	8	6	`Contact.enroll`
Mailboxes	The addresses your agents send from, warmed, rested and authenticated, with every Suppression and Consent read before each send.	9	9	`Message.broadcast`, `Message.schedule`
Scheduling	A booking link into each seat’s free hours, so an interested reply becomes a booked Meeting with a brief, not a thread of emails.	4	2	`Meeting.book`
Social	Posts from your own accounts on LinkedIn, X, Reddit, YouTube, TikTok and Instagram, published or scheduled by one call per site.	6	5	`Post.publish`, `Post.schedule`
Ads	Audiences, Campaigns and Ads on your own Meta, Google, Bing, LinkedIn, Reddit, X and TikTok ad accounts, spent only under a standing approval.	6	6	`Ad.create`, `Audience.create`, `Campaign.create`, `Campaign.update`
SEO	The search terms and AI questions your pages target, where each ranks, which answers cite you, and whether every page is indexed.	4	4	None.
Sites and content	Your Site, its pages and the Content on them, drafted from what ranks, published by one call, and submitted to search engines on every publish.	8	6	None.
Media	Videos, images and voice made from your records, cut to each site’s format, and finalized only once every claim reads from a live record.	6	6	None.
Forms and waitlists	Forms and Waitlists turn a visit into a lead, and the Visitor record joins earlier visits to the Contact once they sign up.	6	6	None.
Analytics and experiments	Every visit and Event as Metrics you query, watch and test against, so each Play is read by its number and not by a hunch.	9	8	`Metric.query`

The action Verbs are where your agents act

Each action Verb has its own page: Inputs, Outputs, Effects, what each site honors, what try does, and what refuses it. The four account calls (Integration.connect, Integration.call, Handle.connect and Mandate.authorize) live under Integrations.

Verb	System	What it changes	Page
`Post.publish`	Social	Puts a Post live from your account on one site, by API or by a browser agent signed in as you	Post.publish
`Post.schedule`	Social	Places a drafted Post on its account’s calendar for a set time	Post.schedule
`Message.schedule`	Mailboxes	Holds one Message until its send time, then sends it from your Mailbox	Message.schedule
`Message.broadcast`	Mailboxes	Sends one Message to an Audience, now or at a set time	Message.broadcast
`Contact.enroll`	Sequences	Starts each Contact on a Sequence, which stops on any reply	Contact.enroll
`Meeting.book`	Scheduling	Books a Meeting at a time both calendars hold free	Meeting.book
`Audience.create`	Ads	Matches a saved list of Prospects or customers to an Audience on your ad account	Audience.create
`Campaign.create`	Ads	Creates a Campaign on your ad account, with its stop rule, on spend you authorized	Campaign.create
`Campaign.update`	Ads	Changes a live Campaign’s budget, bids or status	Campaign.update
`Ad.create`	Ads	Adds an Ad, with its creative in the site’s format, to a Campaign	Ad.create
`Metric.query`	Analytics and experiments	Nothing: it reads a Metric as a trend, funnel or retention curve	Metric.query
`Lead.qualify`	CRM	Confirms a lead fits an offer and opens a deal for it	Lead.qualify

Every call takes the same four forms on one key

A System Verb is one Tool under one name on every Interface: the SDK, the REST API, the CLI and the MCP do tool. In try mode the call reads and plans, stores nothing and sends nothing.

TypeScript

import { $ } from 'startup-builder'

const plan = await $.try.Contact.enroll({
  audience: 'audiences/heads-of-operations',
  sequence: 'sequences/first-touch',
  from: 'dana@tryleaseline.app',
})

Terminal

npm i startup-builder@0.3
npx startup-builder do Contact.enroll --data '{"audience":"audiences/heads-of-operations","sequence":"sequences/first-touch"}'

Every change emits one Event you can hear

Each write emits the Event named for its Verb, such as Contact.enrolled or Post.published, and a webhook carries it out. A Trigger can start a Workflow on it unchanged, and Metric.query reads it back. Events and webhooks lists every one.

Every send passes one check before it leaves

Before any Message, Post or enrollment goes out, the platform reads Consent and every Suppression, the Mailbox cap and your standing approval that covers the send. A failed check refuses that one send with its code and its fix, listed at Checks, and the rest of the batch goes on.
