Test algorithms with simulated users before deployment

The Problem

ML changes ship blind

Recommendation models and ranking changes go live with zero behavioral coverage. A/B tests take weeks. By then, the damage is done.

Tests don't reflect real usage

They validate output metrics, not behavior. The metrics may look good while real user journeys quietly degrade.

User behavior is sequential

Search, recommendations, and agents evolve over sessions through queries, clicks, and feedback loops. Static evaluation misses how systems actually behave over time.

The Solution

Digital twins testing out the ML product

01

Summarize key trajectories

Distill real user sessions into representative behavioral patterns that capture how people search, click, and adapt.

02

Evaluate full user journeys

Test how experiences evolve across sessions. Surface degradation in ranking quality, navigation paths, and feedback loops before release.

03

Understand impact before release

See how changes influence engagement and outcomes without exposing real users.

04

Minimize risky exposure in A/B tests

Enter experiments with stronger confidence and fewer unknowns.
