Ontology: one map of records, rules and relationships. Every app and agent works from it.

Complete AI-native infrastructure, from data to deploy.

Most companies stitch together a database, hosting, auth, a warehouse, pipelines and BI, then need engineers to keep it all running. SegmentStream replaces all of it with one managed platform.

One foundation for everything

The operating system for the whole company: people, apps and agents.

Connect your data and systems, define how your business works, and every app, agent and workflow runs on it, with roles and permissions built in.

Connect your tools and data sources once. Credentials stay with the platform, never in your code.

What companies build on it.

AI-native software and internal tools for sales, finance, marketing, operations, and support. Each built on the same building blocks and the same records.

Moving from another tool?

Your data comes over with its history while the old system keeps running. Our engineers can do the whole move.

Deals by stage, per product, with owners and close dates. The stages are ours, and so is the rule that only sales and growth see amounts.

For enterprises

Forward-deployed engineers, a fixed-scope pilot, roles and permissions, change history on every record, and EU or US data residency.

Enterprise features →
Company agent

A company agent in every team chat.

One agent that knows your company’s records and rules, in Slack, Teams, WhatsApp, Telegram and email. Your team asks it, assigns it work, and approves what it does.

  • Acts as the person asking

    Each person connects once. The agent answers with their permissions, and every change is recorded as theirs.

  • Asks before it acts

    Before it changes anything that matters, it shows the change and waits: confirm, edit or cancel.

  • Reads what your team sends

    Invoices, contracts, scans, spreadsheets and voice notes: it reads them and files what matters on the right record.

  • Works when nobody asks

    Every agent has its own inbox, and workflows start it on a schedule: it reconciles, follows up and reports back.

How the company agent works →
Workflows

Routine work, done without anyone remembering to do it.

Workflows start the work on a schedule, when a record changes or when another service calls, and hand it to the company agent when judgement is needed. Each runs under the same rules as your team and reports to a person when a decision is theirs.

  • Every morning at 07:00

    Reconcile the books

    Matches yesterday’s bank transactions to invoices and bills, and posts the three that don’t match to #finance with a suggested fix.

  • Weekdays at 08:00

    Follow up on leads

    Finds the leads nobody has followed up for three days and asks each owner in their chat whether to send the drafted follow-up.

  • When a deal is won

    Prepare the contract

    Drafts the contract from the deal and the client’s record, attaches it, and asks finance to approve before it goes out.

  • When an email arrives

    Sort the inbox

    Reads each new message to the shared inbox, files it on the customer’s record and flags the ones that need a reply today.

  • Every Sunday night

    Clean the CRM

    Merges duplicate companies and contacts, fills missing fields from your connections and lists what it could not resolve.

  • When Stripe calls

    Record a payment

    Records the payment against the invoice, updates the client’s balance and thanks them from your own domain.

Your code

Not another SaaS. Software your company owns.

Every app, the company database, workflows, pipelines and the agent are code in a git repository that belongs to your company. Clone it, keep a copy on GitHub, take it with you. Each push to main deploys that exact commit to SegmentStream.

Our own workspace repository. The folders our company runs on, the map of what each one does, and the command that clones them.

Any AI agent. The same rules for all of them.

  • Your own agent

Build with Claude, Codex or Cursor, and work with Claude or ChatGPT. Each agent acts as the person using it and sees only what their role allows. Your data, metrics and rules live in SegmentStream, not inside the agent, so you can switch any time.

Two ways to start.

Have us build it

Enterprise, with our engineers

Our engineers build the software your teams need in your own workspace, or move over what you run today, as code you own. It starts with a fixed-scope pilot.

Build it yourself

Self-serve, with your own agent

Install the CLI and tell your coding agent what your team needs. It creates the workspace, builds on the platform and deploys. Pay only for what runs.

“Agents will keep changing. Your company’s context shouldn’t have to. Keep it in one place you own, and every agent starts from what your team already knows.”
