Audiences, campaigns, lead scoring and attribution on records you own.
Audiences, campaigns, consent, lead scoring and attribution in your own workspace, on the same records as sales. Ten years of SegmentStream measurement, now one layer you can run on SegmentStream, with our experts if you want them.
Our engineers build it with you, or your team builds it with its own agents.
Sound familiar?
A customer in five places
Every tool keeps its own copy of the customer, and none of them agree.
Audiences in the wrong place
Consent lives in the email tool, leads in the CRM, and the two disagree.
Platforms grade their own homework
Every platform claims the same conversion, and the totals add up to more than revenue.
Campaigns that run themselves, by your rules.
Preparing and sending campaigns, unsubscribes and delivery events as workflows, each checking consent before anything goes out.

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.
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. You pay only for what runs.
curl -fsSL https://segmentstream.com/install.sh | shBuilt for other teams too
Start a pilot.
Our forward-deployed engineers build one solution on your data, in your own workspace, as code you own. Tell us what you run today and what you want; your note goes straight to our founder.
- One solution, on your data, in your own workspace
- First version live in two weeks
- Parity proven before anything is switched off
- Fixed scope and price, credited to your contract if you continue
Not ready for a pilot? Send the form anyway with your question. An engineer will reply, not a sales rep.
