AI-systems implementation

Florida · est. 2018

The operating substrate companies run on.

AI systems for the companies that actually run things. Workflow automation, multi-agent orchestration, and the operating substrate underneath. Built with civil-engineering discipline (FL EI, MSCE, PCI Journal coauthor); shipped as production software.

First principle

Engineering judgment runs end-to-end. Specification, design, code, and field operations all live inside the same practice. No handoffs between thinking and shipping.

Every deliverable lands as engineering work first and runs in production as software second, because they were actually built, not slide-decked.

Background

AI systems by practice.
Engineering-grade by training.
Founded in Florida, 2018.

Rarefied Earth was founded in 2018 in Florida to take graduate-level engineering discipline and apply it to AI systems and the operating substrate companies actually run on. The research-dominant background gives the engineering its grade; the software practice gives the systems their ship date.

Research-dominant

The firm's methodology comes out of five years inside USF's structural and materials labs. In-situ corrosion diagnostics on the Sunshine Skyway Bridge under Dr. Alberto Sagüés. A full MSCE thesis under Dr. Gray Mullins, P.E., on epoxy injection and carbon-fiber restoration of corroded prestressed-concrete pile bents. Co-authored peer-reviewed work in PCI Journal in 2025.

Field-grounded

Every workflow tool starts from time spent on the actual job: soil borings, bridge inspections, forensic site walks, drone flights, and underwater structural dives. The software exists because the field work made the gaps obvious.

Independent

Florida S-corporation. Direct delivery model. No agency markup, no subcontracted dev shop, no opaque platform clients can't self-host. The firm builds on standard tools (Python, PostgreSQL, FastAPI, Anthropic API) so any competent engineer can pick up the work later.

Build the Company · the productized offering

The operating substrate
Rarefied Earth runs on,
deployed into yours.

Eighteen months of operating substrate, refined in production on Rarefied Earth itself. Packaged as a single engagement that installs the same substrate into your company.

Where it lives

Your workspace.

Deploys as a filesystem layer into your Cursor workspace. No separate portal, no separate login, no SaaS surface.

What it connects

Your accounts.

Integrates with your own Stripe, Linear, Sentry, and Anthropic accounts. Your credentials, your data, never ours.

How it's operated

Via Cursor.

Your team's existing AI-assisted IDE is the operational surface. Agents are substrate-aware from the day of deployment.

Who owns it

You do.

Every byte of substrate state lives on your infrastructure. If Rarefied Earth disappears tomorrow, the substrate keeps running.

01 · What deploys

Twenty canonical modules.

  • Foundation
    Cross-Agent Context, Folder Taxonomy, Brand Starter Kit, Operator Protocol, Agent Charter
  • Voice + Capture
    Voice Guide, Mail Capture, Cursor Session-Start Hooks, Freshness Layer
  • Time + Money
    Cursor Session Attribution, Time + Billing Pipeline, Data Management Policy, Pattern Log, PDF Pipeline
  • Amplifier
    Agent Skills Layer, Client Onboarding Runbook + Script, MCP State Server, Cursor Cloud Agents, Shell Conventions
  • Growth
    Automated product flywheel

02 · How it ships

Five phases, one week of discovery.

  • Discovery week inside the client's daily operation
  • Five-phase deployment with modules layered in sequence
  • Every module customized to the client's voice, brand, and verticals
  • Engineering-led delivery; client-owned at handover
  • Audit pass and tuning session at 30, 60, and 90 days

03 · Why it earns its keep

The substrate ships debugged.

  • Every module is field-tested on Rarefied Earth before it deploys to a client workspace
  • Clients are the second installation, not the first to hit a bug
  • One setup fee plus monthly recurring; pricing scopes to substrate complexity, not a tiered SKU list
  • Architecture compounds across deployments; lessons from one client improve every future engagement

Capabilities

AI systems, engineered.

An AI-systems practice on one side, an engineering practice on the other, run as one integrated firm. AI is the work; engineering credentials are the discipline that makes the AI work serious. Engagements draw from either or both, depending on what the work calls for.

A

AI-systems practice (the work)

AI systems, agent orchestration & full-stack development.

  • AI & decision systems

    Anthropic and OpenAI APIs integrated into grounded, auditable decision logic. Human-in-the-loop by default. Multi-agent orchestration with credential boundaries and voice-rule enforcement. Built on the same architectural principles as the internal Chloe framework.

  • Workflow automation

    Document intelligence, sub bid leveling, spec parsing, field-note digitization, estimate-versus-actual feedback loops. The mechanical work that operators spend hours on, compressed to minutes.

  • Full-stack development

    Custom internal portals on Python, FastAPI, PostgreSQL, Microsoft 365 SSO. Integrations into Procore, Foundation, Primavera P6, WorkMax, and Excel. One role-based hub instead of five disconnected tools.

B

Engineering practice (the wedge)

Structural, forensic, and field engineering.

  • Structural design & analysis

    Bridge and structural design under FDOT Structures Design Guidelines, Standard Specifications, and Standard Plans. Construction plans, calculations, load ratings, rehabilitation design, post-design engineering services, and shop-drawing review.

  • Forensic investigations

    Cause-and-origin work, post-event damage assessment, failure analysis. Technical reports for insurance carriers, adjusters, and counsel. Photographic and GIS documentation built to hold up in litigation.

  • Inspection & field operations

    Bridge and structural inspection, geotechnical field work, FAA Part 107 commercial UAS for aerial documentation, AAUS scientific dive for underwater structural assessment. Field operations integrated with the engineering deliverable, not subcontracted.

Approach

How the work runs.

The firm commits to what can be shipped to production quality, not what looks impressive on a slide. The result: tools that get used, not tools that get demoed once and forgotten.

01 / SHADOW FIRST

Watch how it actually works.

Most construction-tech rollouts fail because someone built the wrong thing very well. Engagements start with shadowing: weeks spent observing how your team actually works before any code gets written.

02 / HUMAN-IN-THE-LOOP

AI drafts. Humans approve.

Field notes show the original photo alongside the extracted data. Daily reports require sign-off. The AI doesn't need to be perfect; it needs to be helpful.

03 / NO LOCK-IN

Standard tools, no proprietary anything.

Python, PostgreSQL, FastAPI, Anthropic API. Any competent developer can pick up the work and maintain it.

Client experience

A client portal built like the rest of your software.

Engagements run on a self-serve client portal. Invoices, project status, and payment all live in one account, accessed the same way clients access their other vendor tools.

01

Self-serve invoices

Approve, download, and pay invoices through your account. Email notifications when an invoice awaits sign-off.

02

Multi-rail payments

Stripe for cards and ACH bank-connect. Coinbase for crypto. Whichever rail your finance team prefers.

03

QuickBooks accounting

Invoices, payments, and reconciliation flow into the firm's QuickBooks ledger. Clean books, clean audit trail.

04

Secure bank connect

Bank-grade authentication via the Stripe rail. No paper checks, no manually-typed routing numbers.

Current work

Leadership

Led by an engineer who ships production code.

Joseph Scott. Five years of graduate structural research at USF, FDOT bridge engineering, forensic investigation work, and full-stack software development on one bench. The firm runs as a direct engineering relationship: the person reviewing your stack is the person writing the code.
