# Create and seed custom AI segments

Your first-party data is often your strongest signal. DS-1 helps you turn that signal into scalable audience intelligence.

### How it works

{% stepper %}
{% step %}

#### Create and place a pixel

Create and place a pixel, then use its collected data to seed custom AI segments.
{% endstep %}

{% step %}

#### Seed a custom AI segment

DS-1 starts with the people you already know.
{% endstep %}

{% step %}

#### Expand your audience

DS-1 identifies people with similar characteristics. Your existing audience becomes the foundation for a larger, more relevant segment.
