Operating systems

The Platform
Six verticals.
One operating system.
Each product targets a specific industry workflow, runs on shared infrastructure, and integrates with the rest of the platform. Customers buy individual capabilities and adopt the platform as their needs grow.
HookGrade
Creator analytics for YouTube thumbnails
Vision-model scoring across five performance dimensions — click appeal, emotion, contrast, readability, and face prominence — with prescriptive recommendations. Ships every thumbnail with a verdict before it's published.
Federal Data Infrastructure
211 government data feeds on a unified API
SEC EDGAR, FDA recalls, BLS CPI/JOLTS, NOAA weather, FEMA disaster declarations, USAspending, Census, and 200+ more — a single API contract across the public-data graph. Pay-per-event pricing built for production workloads.
Tendia
Property operations OS for small portfolios
Tenant intake, AI triage, vendor cascade dispatch, photo verification, invoice generation, and tax-ready ledger — the back office of a property management company, automated end-to-end. Built for 1–500 unit operators who can't afford AppFolio.
Grid Bot Pro
Production grid trading for Kraken & Coinbase
Geometric grid spacing, multi-layer risk gates, SQLite crash recovery, real-time Telegram alerts, and a built-in backtester. Lifetime license, source included, runs on a $5/mo VPS.
Eyrie
Competitive pricing intelligence
Real-time price monitoring across competitor URLs with multi-channel alerting and an AI strategy assistant. Shopify-native one-tap reprice. Built for merchants and SaaS founders who refuse to lose deals to a thirty-cent price gap.
PromptVault
Production prompt library, versioned and tested
A curated library of prompts validated at scale across frontier models. Versioned, model-aware, and refreshed when foundation models update. Built for teams who treat prompts as production code.
How we work
Vertical depth.
Operational rigor.
Software that runs itself.
The work humans hate doing — dispatching contractors at 2am, reconciling a thousand grant invoices, scoring every thumbnail before publishing — is exactly the work software should be doing. AeternaOS is the company building that software for the industries that need it most.
Built for production
Every product on this page runs against real workloads today. Nothing is a pitch deck. Nothing is theoretical. Software ships when it's ready to handle traffic at scale.
Engineered for unattended operation
Our systems are designed to handle the work humans shouldn't have to. Dispatch, triage, reconciliation, compliance — automated end-to-end with audit trails, not dashboards.
AI underneath, outcomes in front
Customers see results — emergency tickets resolved, click-through rates improved, compliance gaps closed. The machine-learning layer stays out of the way. You don't pay for tech you don't understand.
Vertical depth over horizontal sprawl
We build for specific industries with specific compliance, vendor networks, and regulatory pressure. Generic platforms lose to vertical ones at the seams. We live at the seams.
