Engineering-grade AI for operating companies.
Rarefied Earth is an AI-systems implementation firm for operating SMBs. We build AI-augmented workflow automation, agent systems, and the operating substrate companies run on. Florida S-corporation (Earth Evocation Inc. d/b/a Rarefied Earth), founded 2018, based in St. Petersburg.
Your agents should know your company.
Groundwork is the public product name for the operating substrate Rarefied Earth runs on itself (internally: Build the Company). One system, two layers: BtC is the package; Groundwork is what customers buy and agents connect to.

- AI-systems implementation for the companies that actually run things: workflow automation, document intelligence, multi-agent orchestration, custom internal portals.
- Civil-engineering depth where it counts. The founder is a Florida Engineer Intern, MSCE (structural), and a coauthor of peer-reviewed prestressed-concrete restoration research in PCI Journal. In heavy-civil and construction-adjacent verticals, the credentials are the trust wedge.
- Groundwork, the productized layer: company memory, voice rules, billing, capture, and agent skills installed into the tools a team already uses.

Voice, brand discipline, agent charter. How the firm operates. |

Internal R&D framing. Trading was the test domain. Code stays private. |
Client engagement repositories, the ops substrate, and the thinking vault are private by design.
- Dogfood first. Every system ships to a client only after it has run on Rarefied Earth's own pipeline.
- Human-in-the-loop. AI drafts; humans approve. Irreversible actions sit behind a gate.
- No lock-in. Python, PostgreSQL, FastAPI, standard APIs. Any competent engineer can pick the work up later.
- Founder-operated. Joseph Scott, EI, MSCE · @saltymaverick
