Ten areas, one workspace

Each area has its own screens and shares the same contacts, permissions, approvals and audit log.

Email outreach

Campaigns that pass a safety check before they leave.

  • Templates with saved versions; a campaign sends a published version
  • Sequences with follow-ups and optional A/B tests
  • A safety check, a test email and approval before launch
  • Sending windows, hourly and daily limits, and scheduled starts
  • Automations that enrol contacts on a trigger and stop on exit conditions

Social publishing

Write a post once, adapt it for each account, publish after approval.

  • Connect accounts by logging in at the platform or with an access token
  • One post with its own version per account, checked against each platform's rules
  • Approval tied to the exact content, then schedule or publish
  • A calendar, a media library and saved hashtag sets

Advertising

Recommendations first. Changes only inside the limits you set.

  • Connect Meta Ads and Google Ads, and sync structure and daily metrics
  • Recommendations from fixed rules and from agents, each part labelled by its evidence
  • An approval level per ad account, from read-only to automation inside guardrails
  • Guardrails, a kill switch and a ledger of every change

Marketing Brain

State an objective, approve the plan, follow the run.

  • An objective is matched to a workflow from a fixed catalog
  • A person approves the plan before anything runs
  • Runs go step by step, stop at human gates and keep to an AI budget
  • A run creates drafts, recommendation links, insights and reports, and nothing else

Market intelligence

Collect what is happening, and keep facts apart from inference.

  • Sources: public feeds, public pages, Apify actors and your own results
  • Tracked topics and observations, each with its source and time
  • Competitor tracking with snapshots over time
  • Insights written by agents, always labelled as AI inference

Audience

Know who you may contact, and on what basis.

  • Contacts and businesses with tags, custom fields and a timeline
  • CSV import with column mapping and a quality report before anything is saved
  • Segments from rules that stay up to date, or fixed lists
  • Suppressions and consent status, applied to every send

Inbox and CRM

Turn replies into leads, tasks and meetings.

  • A reply inbox with classifications; an unsubscribe request suppresses the address
  • One lead per contact on a pipeline board, with tasks and notes
  • Lead scoring from fixed signals you can read one by one
  • Meetings logged by hand or received from Cal.com and Calendly

AI providers and agents

Use the models you choose, within the budgets you set.

  • Connect OpenAI, Anthropic, Google Gemini, xAI, DeepSeek or an OpenAI-compatible endpoint
  • Routing with fallback, and a model policy per agent
  • Budgets that cap what AI may spend, with a usage record per call
  • AI Studio: tasks that plan, write, review and explain

Analytics and attribution

Numbers that say what they rest on.

  • Every rate shows its basis and is flagged when the sample is small
  • Attribution models: last non-direct touch, last touch, first touch and linear
  • Tracked links and the journey of each contact
  • CAC and ROAS per currency; currencies are never added together

Administration

Decide who may do what, and see who did.

  • Roles made of permissions, including custom roles
  • An audit log whose integrity can be verified
  • API keys with a permission ceiling, and two-factor authentication
  • Compliance profiles with consent rules and sending hours

From a connected account to a measured result

The same five steps apply to an email campaign, a social post and a change to an ad account.

  1. Step 1: Connect

    Add an email provider, an AI provider and your social and ad accounts. Credentials are stored encrypted and are not shown again.

  2. Step 2: Build your audience

    Import contacts, read the quality report, record consent and group people into segments.

  3. Step 3: Create and approve

    Write templates, campaigns and posts, with AI drafts where you want them. A second person approves the exact content.

  4. Step 4: Send and publish

    Approved campaigns send inside their sending window. Approved posts publish at the time you scheduled.

  5. Step 5: Measure and learn

    Read replies, leads, meetings and attribution, then act on the recommendations.

People stay in control

AI provides drafts and recommendations. Fixed rules and signed-in people decide what happens. These safeguards are part of the product, not settings to switch on.

  • AI
    Drafts and recommends
    People and fixed rules
    Approve and execute
  • Human approval and four eyes

    Campaigns, social posts and ad changes are approved by a person, by default not the one who asked. An approval covers the exact content it was given for.

  • AI never sends, publishes or spends

    Agents run without permissions. They cannot send, publish, approve, change an ad account or lift a suppression, whatever they are asked.

  • Spend limits enforced in code

    Whether a change to an ad account is applied is decided by fixed rules over limits your administrators set, never by a prompt.

  • Safety check before launch

    A campaign passes a checklist on the server before it is submitted, approved, scheduled and launched. A blocking failure stops it.

  • Suppressions always win

    A suppressed address is left out of every send. Only a signed-in person with the permission can lift a suppression.

  • Evidence labels

    Observations and insights are labelled External data, Internal performance or AI inference. An inference is never stored as an observed fact.

  • Hash-chained audit log

    Sensitive changes are recorded in an append-only log. Each entry is chained to the one before it, so a changed or removed entry is detected.

  • Write-only, encrypted secrets

    Keys and tokens are stored encrypted, shown at most as a masked fragment, and never given to an AI model.

  • Tenant isolation

    Every record belongs to one organization, and data is read and written within that organization only.

  • Role-based access

    Every action checks a permission. A role is a set of permissions that an administrator can tailor.

Built-in connectors

Connections are made by an administrator inside the product, with a login button or a key, depending on the service.

Questions, answered plainly

What is GrowthOS?

A workspace for B2B marketing and client acquisition. It covers contacts and segments, email campaigns and automations, the reply inbox and lead pipeline, social publishing, advertising, market intelligence, analytics and attribution, with AI agents that draft and recommend.

Does the AI send or publish anything on its own?

No. Agents run without permissions: they cannot send, schedule, approve or launch a campaign, publish a post, change an ad account or lift a suppression. What an agent produces is a draft, a recommendation or an insight, and it stays inert until a signed-in person acts on it.

What stops a mistake from going out?

Several things. A campaign passes a safety check before it is submitted, approved, scheduled and launched. Campaigns, social posts and ad changes are approved by a person, by default not the one who asked, and an approval covers the exact content it was given for. Suppressed addresses are left out of every send. Every action checks a permission, and sensitive changes are written to the audit log.

Which platforms does it connect to?

OpenAI, Anthropic, Google Gemini, xAI and DeepSeek for AI; LinkedIn, Facebook Pages, Instagram, Threads, X, YouTube, Google Business Profile and TikTok for social; Meta Ads and Google Ads for advertising; Amazon SES or any SMTP server for email; Cal.com and Calendly for meetings; and Apify as a lead source. The connectors are built in, and each one uses your own account with the service.

Can I use my own AI provider?

Yes. An administrator connects one or more providers, chooses which model each agent uses and sets budgets that cap what AI may spend.

How is data protected?

Each organization's data is kept apart from every other's. Access is checked by permission on every action, two-factor authentication can be required, credentials are stored encrypted and cannot be read back, and sensitive changes are written to an audit log whose integrity can be verified. Backups and the security of the server belong to whoever runs the installation.

Is there a hosted or SaaS plan?

Not yet. There is no public sign-up today: an administrator invites each person to an existing workspace. A hosted service with self-service sign-up and plans is planned and is not available yet.

Where is the documentation?

A user guide is built into the product under Help, with a chapter for each screen, a quick start and a glossary. It opens after you sign in.

Your workspace is one sign-in away

Accounts are created by invitation from an administrator. If you have one, sign in to continue.
