# Tellstone

> Tellstone is team due diligence software for venture studios and accelerators. We help studios assess founding-team dynamics — compatibility, role fit, stress behavior, and blind spots — before they commit capital or cohort seats.

Tellstone runs a short behavioral simulation with each founder (about 20 minutes), then produces a team-level report covering cofounder compatibility, decision-making style, conflict patterns, and role coverage gaps. Studios use it to break ties in final selection, validate instincts from interviews, and surface risks not visible in pitch meetings.

## Who it's for

- Venture studios building or pairing founding teams
- Accelerators making final cohort selection decisions
- Early-stage investors evaluating team risk pre-check

## What makes it different

- Built specifically for founding-team dynamics, not general workplace personality (unlike DISC, Predictive Index, Gallup)
- Behavioral simulation, not self-report questionnaire — founders can't game it the way they game interviews
- Outputs are decision-ready: role fit, pairing risk, missing-piece hire profile
