About Vevang AI
We run our own books on it.
Vevang builds the AI Operating Partner and the AI CFO — and operates its own business on them. Every claim on this site traces to something running in production, because we are the first customer of everything we ship.
The mission
Close the software gap between the Fortune 500 and Main Street.
Palantir-grade technology for every business in America — at a price every business can afford.
“Palantir-grade” is earned in the mechanisms, not the adjective: per-tenant isolation enforced by the database, money-out locked to human approval forever, append-only audit spines under every action, and AI answers that cite the exact ledger entry or document they came from. The world’s biggest institutions run on software built this way. A landscaping company in Ohio doesn’t — it runs on spreadsheets, a part-time bookkeeper, and memory. Vevang exists to end that, at $10 to $2,500 a month instead of a seven-figure contract.
The thesis underneath it: every sales tool guesses “best customer” from clicks. We own the books, so we know who actually paid and left margin.Money-truth and growth-truth on one graph — that’s the whole company in one sentence.
The founder
Built by an operator, for operators.
Eric Vevang
Founder
Eric founded Vevang AI and leads the design and engineering of the platform — the ledger kernel, the agent runtime, and the trust architecture that locks money-out to human approval. He runs Vevang’s own operations and books on the products themselves, which is why the honest limits on this site read the way they do: they’re his limits too.
Eric is the byline behind Vevang’s citable pages — including the canonical definition of the AI Operating Partner.
What we build
Three products, one intelligence
AI Operating Partner
Command
The flagship: a real double-entry ledger plus an agentic salesforce on one ontology. Agents propose, you confirm, money-out is human-only at the database. From $1,500/mo.
Explore CommandYour AI CFO
Finance
The same intelligence pointed at your money alone: automatic books, exact cited answers, banker-ready reports, and a Watch that tells you first. From $10/mo, self-serve.

Agents
Custom multi-agent systems built on the same governed runtime — specialist agents, a synthesizing director, and honest live-vs-simulated labeling throughout.

The house rules, in public
- No cached balances anywhere. Every figure is computed live from posted ledger lines. A stale number is a lie with a timestamp.
- No LLM ever computes a money figure. The AI proposes, cites, and explains; deterministic code does the math.
- Failures say so. A failed read dims its tile with the reason — never a fake 0, never a guessed value.
- Agents propose. Humans confirm. Autonomy is earned and governed; money-out never gets it.
- No free tiers, no trials. Payment is the gate — it keeps the bots out and the incentives honest.
- We dogfood everything.Vevang’s own books run on the platform. When something breaks, it breaks on us first.
