I build AI products that hold up to real users and real audits. Approvals, audit trails and tenant isolation before demos.

Vault AI

An AI workspace built for trust, not demos.

Multi-model workspaces, personas, knowledge bases, document processing, a realtime gateway, tenant isolation, audit verification and production guardrails. Built for teams whose AI use has to hold up to review.

Read the case study

problem

Most AI workspace demos collapse once a second tenant, a compliance reviewer, or a confidently wrong model shows up. Teams needed one place to use several models without losing control of their data or their audit trail.

what i built

A tenant-isolated workspace with per-tenant checks on every data path, human approval gates on consequential actions, verifiable audit records, and a realtime gateway that keeps voice and streaming inside the same guardrails.

what broke

Early guardrails lived in the UI. The first integration that bypassed the UI proved they had to move into the API layer, where they now sit next to the tenant checks.

what i'd do differently

Design the audit model before the first feature, not after the first customer asked for it. Every later system was easier because the trail already existed.

Arden AI / Haven Local

Local-first AI with human approvals.

Local model execution, scoped permissions, auditable actions, and a conservative interface for people who are not technical and do not want to be.

The long way to software

Seth Nordgren
seth nordgrencolumbus, oh

I finished a PhD in psychology before I shipped a single line of production code. I still think the most interesting software is the kind that respects how people actually work, not how a spec assumes they do.

That perspective shapes everything I build: AI workflows with human review, dashboards that surface the next decision, compliance tools designed around the moments people are most likely to skip a step, and mobile apps that respect attention instead of capturing it.

As CTO of Enigma Software Systems I lead product and engineering for AI tools that have to hold up to real audits, real scale, and real humans. Vault AI is the flagship, and the same thinking shows up in everything else I touch.

Outside Enigma I ship a lot: iOS apps, compliance tools, CRMs, dashboards. The throughline is not a stack. It is that every project is a small experiment in making software that gets used, not just installed.
