Software Built to Make Connections

Our Story

The story of Double Helix Software began long before the company itself…

Stemma™

Stemma™ was designed around the idea that the family tree should be the center of the research environment.

Our Approach

Many of the best software ideas begin with someone saying, “There has to be a better way to do this.”
