Predictable AI for critical infrastructure
Fathom is Olea's AI analytics suite built for the work that keeps utilities running. It pairs a conversational analytics interface with a deterministic workflow runtime so operations teams get trustworthy answers and repeatable processes — not black-box guesses.
What is Fathom?
Fathom brings AI analytics to critical infrastructure without the uncertainty. It combines Poseidon, a conversational interface that lets teams query their operational data in plain language, with Trident, a deterministic workflow runtime that processes data through auditable, repeatable pipelines. Together they deliver intelligence you can trust and results you can prove.
Ask Poseidon anything
Poseidon is Fathom's chat-based analytics interface. Operations teams ask questions in plain language and get AI-powered answers grounded in their actual data — device readings, meter health trends, pressure histories, and more.
Behind the scenes, Trident workflows feed pre-computed summaries into Poseidon's context while its agent queries remote data sources directly when deeper analysis is needed. The result is fast, accurate, and auditable.
- Ask questions about meters, devices, readings, and network health in natural language.
- Answers are grounded in live operational data, not generic training sets.
- Every response traces back to the source query and data it used.
- Works alongside existing dashboards — complements, does not replace.
Predictable AI for the work that matters
The AI industry is racing to build the most capable personal assistant. Products like OpenClaw — the open-source project that rocketed to 160,000 GitHub stars in weeks — promise an AI that can do anything: manage your inbox, browse the web, write its own new capabilities on the fly.
That vision is compelling. It is also the opposite of what government agencies and enterprises need.
When a municipal water department processes thousands of meter readings per day, or a defense contractor runs compliance checks across a procurement pipeline, the question is not “can AI figure this out?” The question is “will it produce the same reliable result every time, and can we prove it?”
That is why we built Trident.
What Trident is
Trident is a lightweight workflow runtime that orchestrates AI along predetermined paths. You define the steps. You define the inputs and outputs. You define the branching conditions. The AI provides intelligence at each step, but the process belongs to you.
A Trident workflow is a directed acyclic graph. Each node performs a specific task — classifying an input, extracting structured data, calling an external tool, making a decision. Edges between nodes carry data with explicit field mappings. Conditions on those edges control which path the workflow takes. Every output is validated against a schema before moving to the next step.
The result is an AI system that behaves less like a conversation and more like a production line.
Why it is different
The current wave of AI agents — OpenClaw, and the many products following its lead — are built around a simple idea: give the AI maximum autonomy and let it decide what to do next. This is powerful for personal use. It is problematic for organizations.
Predictable execution, not open-ended exploration. A Trident workflow follows the same path for the same inputs. There are no surprises. The AI does not decide to take a detour, try a creative approach, or call a tool you did not anticipate. This is not a limitation. It is the design.
Enforced structure, not hopeful formatting. When a Trident node produces output, that output is validated against a defined schema. The runtime does not ask the AI to “please return JSON” and hope for the best. It uses structured output tooling to guarantee the format. Downstream nodes can depend on upstream outputs because the contract is enforced.
Constrained scope, not unlimited access. Each node in a Trident workflow declares exactly which tools it is allowed to use. An agent node that needs browser access gets browser access. A node that extracts text from an image gets image tools and nothing else. Compare this to systems where the AI has broad, unrestricted access to the host machine by default — an approach that has already drawn criticism from cybersecurity researchers who found third-party plugins performing data exfiltration without user awareness.
Resumable by design, not restart from scratch. Trident checkpoints after every successful node. If a workflow fails at step seven of ten, you resume from step seven. You do not re-run six expensive LLM calls and three API requests to get back to where you were. For workflows processing thousands of items, this is the difference between manageable costs and runaway spend.
Why government and enterprise
Organizations operating in regulated environments share a set of requirements that personal AI assistants were never designed to meet.
Auditability. Trident emits structured telemetry for every event in a workflow: which node ran, what inputs it received, what outputs it produced, how long it took, how many tokens it consumed. This is not logging you bolt on after the fact. It is built into the execution engine. When a compliance officer asks “what did the AI do with this data and why,” the answer is in the trace.
Reproducibility. Given the same inputs and the same workflow definition, Trident follows the same path. The workflow manifest is a versioned artifact. You can diff it, review it, approve it through your change management process, and deploy it with confidence that it will behave the way it did in testing.
Minimal infrastructure. Trident coordinates workflows through signal files on the filesystem. There is no message broker, no Redis cluster, no Kafka topic to maintain. The entire runtime is roughly 7,200 lines of Python with no heavy dependencies. For organizations where every new infrastructure component requires a security review and an authority to operate, this matters.
Composability without complexity. Workflows can call other workflows. A document processing pipeline can invoke a classification workflow, which invokes an extraction workflow, which invokes a validation workflow. Each is independently testable, independently deployable, and independently auditable. You build complex systems from simple, proven parts.
Provider flexibility. Trident supports multiple LLM providers through a pluggable interface. If your organization requires a specific model for compliance or data residency reasons, you change a configuration value. The workflow definition stays the same.
The right tool for the job
AI personal assistants and AI workflow systems are not competing products. They solve fundamentally different problems.
An assistant excels when the task is novel, the user is present, and the outcome is subjective. Drafting an email. Researching a topic. Brainstorming ideas.
A workflow system excels when the task is known, the process is defined, and the outcome must be consistent. Processing meter readings. Classifying support tickets. Running compliance checks. Extracting structured data from unstructured documents.
The AI industry's current fascination with autonomous agents is understandable. Autonomy is impressive. But for the work that keeps infrastructure running, that keeps agencies in compliance, that keeps utilities delivering clean water — predictability is not a constraint. It is the entire point.
Trident gives you AI that follows the path you designed, produces the outputs you specified, and proves it did exactly what you asked.
