Engineering for workthat cannot fail.

ArcRos is an engineering company of innovators and problem solvers. We build clinical software for health, and we are building toward defense. We find what is broken in the field and ship the software that fixes it.

Sectors

Two sectors. One discipline.

We build where software quality changes real outcomes. Health is our primary focus today: the clinics that care for people and the students training to staff them. Defense is where we are building next.

Physician fatigue is an engineering problem.

Clinical software that returns time to physicians. We work on the documentation load, handoff friction, and administrative drag behind burnout, and on the training pipeline that feeds it. It is designed with the clinicians who carry it, not for a buyer who never sees a patient.

Investment thesis

Three convictions

01

Start with the field, not the feature list

Legacy vendors sell modules. We start by mapping how work actually happens: who decides, what breaks, what gets patched manually. The product follows the workflow.

02

Replace incumbents, do not wrap them

Spreadsheets and aging SaaS cannot keep up with policy velocity, public accountability, or field precision. We build software for how operations run now.

03

One team, selective ventures

A senior engineering team works a deliberately small portfolio: health first, defense next. We enter sectors where domain judgment and technical precision compound. Not every exploration becomes a product.

Health / Portfolio

Clinical software, first

Health is our primary focus. Case Fidelity is the flagship; ArcRos Attending is the second clinical product beside it.

Defense

The sector we are building toward

High-stakes work carried on aging software, with decisions that have to hold up under review afterward: the same constraints we already build against in the clinic. We are in active research and development here. There is no shipped defense product, and we will not announce one before it is real. Arcanum is where the work starts, because institutional knowledge walking out the door is a problem defense feels on every rotation.

03ArcanumInstitutional knowledge that outlasts inboxes and turnover. Replaces tribal memory and scattered docs with a durable, searchable asset. It is the software line we are pointing at defense, where hard-won operational knowledge leaves with every rotation and posting.In development

Arcanum is in development under defense. We have not announced any other defense product.

Capabilities

What we build

Technical themes we reuse across ventures. Some are in production; others are in active development.

01
Problem definition
We extract real workflows from operators and encode them as versioned procedures. What ships reflects field reality, not imagined best practice.
02
End-to-end delivery
From scoped problem through build to what the buyer sees on day one. No black boxes, no handoffs that lose context.
03
Cross-sector build
Shared engineering foundations let a small team deliver across health and defense without rebuilding coordination from scratch each time.
04
Field-grade precision
Imagery, sensor data, and operational signals in; actionable output out. Software first, hardware agnostic.

Operating model

One team. Two sectors.

We publish how we work and where we are building. The parts that need discretion stay internal.
