People
By builders, for people who carry the consequence.
Stonebridge is founder-led and deliberately small. The software is the headcount. The people are the ones who decide what it may do.
Founder & Principal
The principal

Collaborators
Engineers and quants
People who want to work on fail-closed systems with real feedback: broker fills, tax authority rules, tender deadlines. We work from written specs, red-first tests and independent review. See the open problems.
Independent review
A second set of eyes on every change
Every change to every system is reviewed independently before it ships, and the review's verdict travels with the release. We treat this as a structural role, not a favour.
Advisors
Forming
We are assembling a small group of advisors across systematic investing, tax practice and energy. If that is you, the Partner door is the right place to start.
