3Square is the
Decision Intelligence OS
for hybrid-AI teams
100% problem validation based on 100+ interviews with engineering leaders across 50 organisations.
See every decision. Steer every outcome.
Real-time visibility and active guidance across your entire hybrid workforce — human and AI.
What's the point of going 10x speed, if you're going in the wrong direction?
The vast majority of critical business context is trapped in human heads. Agents are now entering the workforce. We're moving from human speed to machine speed. The result? Misalignment, rework and revision. Missed opportunities and risks that compound faster than any team can manage.
We automatically capture decisions as they happen. Org-wide. In existing workflows. With zero overhead to engineers. We build an authoritative, living organisational memory — centred around the why behind every decision made, and the goals it serves.
We supply that intent as context to decision makers at the exact moment they need it — ensuring every decision is grounded in organisational purpose, not just technical correctness.
We provide the active guidance system for decision makers. New ways to direct. New ways to intervene & drive alignment to goals. New ways to manage risk.
Together, these form the new operating system for the hybrid AI workforce. Enabling organisations to make high-quality decisions at 10x the speed.
3Square integrates into existing engineer workflows
Zero overhead to engineers. IDE agnostic. Model agnostic — use any preferred coding agent.
Engineering leaders are already seeing it
100+ interviews. 50+ organisations. 100% recognised the problem.
We tried documentation. We tried wikis. We tried making engineers write things down. None of it stuck. 3Square captures context as a byproduct of how we already work. That's the difference.
Decision trade-offs and compromises are not systematically captured. The technical risk accumulation is invisible until major issues surface — which can cost us millions.
You're systematically capturing decisions, intent, and rationale — which is the company's IP. This may be more valuable than the codebase itself.
