Ephemeris — An AI SaaS We Built to Run Our Own Company

Ephemeris is the AI SaaS Sagan Labs AI built to run its own company — an AI-native business operating system that unifies CRM and finance into one real-time platform, with an SEO command center, an AI daily brief, and a copilot woven through it. We are tenant number one: everything you would ask a client-facing product to do, we do to ourselves first. It is the clearest proof of our AI SaaS development — a multi-tenant, sellable platform we depend on daily.

The Problem

Companies run leads, pipeline, quoting, invoicing, recurring billing, expenses, and per-project profitability across a stack of disconnected tools that never quite reconcile. The founder who wants a single honest answer — what did this project make, what did the whole business make — has to assemble it by hand from exports. AI usually shows up as a chat box bolted onto one of those silos, inventing numbers instead of reading real ones.

Our Approach

Ephemeris merges CRM and accounting into one system so the pipeline and the ledger share the same source of truth, then lets AI do the heavy lifting on top: enrichment, expense classification, and a grounded copilot where every figure comes from a real database call, never a guess. Money is stored as integer cents and the books are held to a trial balance of zero, so the accounting is correct before the AI ever touches it.

The SEO Hub extends the same "one console" idea to organic search: each tenant connects Google Search Console over OAuth, a nightly pipeline pulls rankings, traffic, and Core Web Vitals into daily snapshots, and Gemini proposes keyword targets that a human approves. It is how we track our own marketing — and a module any tenant gets.

Architecture Highlights

• Two products, one truth. CRM and finance share a Postgres schema with row-level security, so multi-tenant isolation is enforced at the database, not the application.
• Correct-by-construction accounting. Amounts are integer cents, never floats; the ledger holds a zero trial balance, verified before and after every change.
• Grounded AI, not invented numbers. The copilot answers only from real query results, and AI keyword suggestions carry a source and an approval gate.
• Audited. An independent six-pass security and finance review passed, with hardening deployed and the books balancing throughout.

Outcomes

Ephemeris's goal is to let a company run itself from one instrument — pipeline, profit, and search performance in a single, trustworthy system — and to prove we can build a sellable AI SaaS by depending on it ourselves.

• Unifies CRM and accounting into one real-time, multi-tenant platform.
• Passed an independent security and finance audit with the books balancing throughout.
• Runs live with 196 SEO keyword targets seeded, tracking our own organic search — Sagan Labs as tenant number one.
