Cardinal Stacks is a US-based studio that builds, rescues, and runs production software for businesses operating under real regulatory weight — healthcare, financial compliance, legal, and SEC-regulated workflows. Every engagement is led by a named senior engineer from scoping through handoff. Direct communication throughout. No junior handoffs, no account manager layers.
We started Cardinal because the existing options for founders and operators in regulated industries were broken in opposite directions. Traditional agencies bury the work under discovery calls, statements of work, and account managers. AI-coded prototypes ship fast but rarely survive contact with real users — let alone an audit. Cardinal sits between the two: a senior team that delivers production software on a flat fee with a written quote in two business days, then keeps it running on a flat monthly retainer.
Cardinal Stacks operates as a senior engineering team with production experience across regulated industries. Three named leaders, US-based delivery, direct communication throughout. No junior handoffs, no account manager layers.
Co-Founder, Technology & AI Systems
Kanji built Cardinal's operating stack (Pulse, Triage, Redactor, Worktree, Bug Catcher, and Scout) and the parallel-agent orchestration methodology that runs every engagement. His background spans AI systems architecture, parallel-agent orchestration, and production software across regulated environments. He shapes how Cardinal deploys AI at the infrastructure layer, from data handling through model orchestration.
Co-Founder, Operations & Strategy
Alex leads operations, client strategy, and go-to-market at Cardinal Stacks. He has founded and operated multiple companies across healthcare AI, medical billing, and SEC-regulated financial services, giving Cardinal direct operator experience in the environments its clients work in. He has personally overseen production deployments under HIPAA, SEC, and attorney-client compliance requirements.
CTO, Chief Software Engineer
Nasir leads engineering delivery at Cardinal Stacks. He brings senior software engineering depth across production systems in healthcare, financial compliance, and AI-integrated platforms. He is responsible for architecture decisions, code quality standards, and the engineering team that executes every Cardinal engagement.

Send a brief — two paragraphs, a Loom, a sketch, a memo, or a finished PRD. We read it, ask any clarifying questions in writing, and send back a written scope plus a flat number inside two business days. If the quote works, we start. If not, you keep the audit. No sales cycle, no upsell, no recurring contact unless you ask for it.
Every Cardinal engagement is delivered against the Cardinal operating stack (Pulse, Triage, Redactor, Worktree, Bug Catcher, Scout) — the same tooling we use to run our own production systems. After launch you own the code, the deploy, the data, and the bill. We hand over a written runbook and 30 days of free fixes for anything that surfaces.
