Sonar is a concentrated investment firm for founders reshaping their industries with software.
The problem found them. Entrepreneurship was the output of their story, not the starting point. Obsessed and incapable of walking away, these founders are building their life's work.
When we find them, we commit deeply — a handful of companies per fund, the full weight of Sonar behind each one.
