For ambitious founders

Discover the business behind your product

What you charge, what each customer agreed to, what they used and what it costs to serve them. Your own agents record it in one set of books, so you can ask what you earned, owe or spent and inspect the record behind every answer.

YC says yes

The standard deal wires $500,000 — $125,000 for 7% on a post-money SAFE plus $375,000 on an uncapped SAFE with an MFN. Cash up — and not a dollar of it is revenue.

We're in — record the YC standard deal.

The first invoice goes out

January's plan plus a credit pack Fern used up within the month: $3,200. Used credits are earned, so it's revenue — and accounts receivable, not cash.

Invoice Fern for January — the plan plus their credit pack.

February grows — and goes red

A second customer and a token overage — but a $5,500 prompt-engineering contractor lands too. Growth isn't margin yet.

Connect your agent

Hand your agent economi.co/skill.md. Your books this time, not Brightforge's.

The shift

The numbers are scattered just when you need to explain them

Founders spend time building their own spreadsheets, pulling metrics from many different sources to answer investor questions. The hard part is not only finding a number; it is knowing what it includes and where it came from. That matters before an investor call and when you make a decision for yourself.

Books from day one

Start with real books

Record your first contract, invoice and payment in an accrual, double-entry ledger. Read the balance sheet and income statement from the same posted activity.

Your agent, end-to-end

Use the agent you already trust

Your agent reaches Economico with scoped access. If it also has access to your inbox or CRM, it can bring the relevant facts into your books. Economico does not connect to those systems for you.

Built for how you bill

Record how your business earns and spends

Set the terms for a retainer, subscription, per-seat or usage contract, or a mix of them. Record invoices, vendor costs and payments against those terms, including supported stablecoin settlements when you use them.

Decisions, not just reporting

Know the number and its source

Ask for revenue, margin, burn and runway from what you have recorded. Inspect the underlying entries and assumptions before using a number in a decision or investor update.

The whole money loop

One record for the work and the questions that follow

Contracts, invoices, vendor bills, usage and credits feed the same ledger as your reports. Open the read-only workspace to inspect what your agent recorded and the numbers it reads back.

Not another AI bookkeeper

Your own agent can run the books

If you already work with agents, they can record finance activity and read reports in Economico. The ledger, documents and reports stay together; access is scoped to the business you approve. Keep your bookkeeper for the books and filings: Economico is your own record beside theirs, for the question you can't wait days to answer.

Who it's for

Made for founders who build their own product

The best fit is a pre-seed or seed founder who builds their own product and already uses a coding agent. Start with a new ledger or scope the setup around your existing books. Raising and bootstrapped founders can ask different questions of the same recorded activity.

Common questions

Frequently asked questions

What is an agent-native general ledger?

A double-entry general ledger your own agents run over MCP or CLI. They record agreements, activity, completed payments, and costs through typed tools, then read the resulting reports. Follow the AI-agent bookkeeping guide or compare the AI bookkeeping landscape.

How is Economico different from QuickBooks or AI bookkeeping tools?

Economico lets the agent you already use record activity in one ledger and inspect the source of a reported number. Compare that workflow with the accounting software or service you would otherwise use. A read-only workspace lets you inspect the same books without creating a second operating surface. Honest head-to-heads live under Compare.

Who is Economico for?

Pre-seed and seed founders who already work through agents such as Claude, ChatGPT, Codex or Grok, whether or not they write the code. Founders who build their own product fit best, because their agent can read pricing and costs from it. Existing books change the setup work; they do not rule you out. Agencies, ecommerce and multi-entity groups are outside our first target. See founder use cases.

What finance work can a solo founder run without hiring finance?

Your agent can create a contract, record an invoice for a customer, record completed payments and vendor costs, track startup credits, and ask for revenue and cash, and for burn and runway once you have recorded enough history. You decide what to do with the answers and move the money through your own bank or wallet.

Do I keep my bookkeeper or finance lead?

Yes, if they're doing the job. They keep the books and filings, and can review the same entries and reports you use. Your agents keep your own record in Economico, so a question doesn't wait for their reply or the next close. Multi-entity accounting and payroll are outside the current product.

Can I invoice in dollars and get paid in USDC?

Yes. Record a dollar-denominated receivable and a completed payment in a supported stablecoin, with the transaction reference and ledger entries. Economico does not initiate the transfer or email the invoice. Read the problem side on paid in USDC and the product side on stablecoin invoicing software.

How do I safely give my agent access to my financial data?

You approve a standard OAuth connection for your own agent, scoped to your Economico business and role. Economico does not get standing access to your email, CRM, bank, or files; your agent remains the integration layer. Review the limits, token controls, and a safe way to try it in the security and permissions guide.

What does Economico cost?

Nothing, for a founder on their own: the Solo plan is the full product for one owner, with any number of connected agents and 100 events a month included. No card required. Startup, for more people and shared views, is $29 a month or $299 a year per company with 1,000 events a month included. See pricing.

How do I connect my agent?

Tell the agent you already use: Set up Economico per https://economi.co/skill.md. MCP-capable hosts connect directly; shell-driven agents use @economico/cli. YC founders verify via a Bookface verify link. Jump to Connect your agent.

  • No new app to learn. Work through the agents you already use, and open the read-only workspace when you want to look
  • Free for a single founder, with 100 events a month included. No card required
  • Real double-entry books: every agreement and activity posts to one ledger you can inspect
  • Your agents stay yours. Economico connects to nothing on its own
  • New company? Start with your first agreement. Existing books need a scoped setup before past-period reports are reliable
  • Every write returns a receipt, and a retry with the same key never posts twice

Before you paste that in

What does it cost to start?

Nothing. A founder on their own gets the full product free on Solo, with any number of agents and 100 events a month. Startup, for more people, is $29 a month or $299 a year per company with 1,000 events a month included. Full pricing.

Do I have to give Economico access to my email, CRM, and bank?

No. Economico does not connect to those systems on its own. If your agent can access them, it can bring relevant facts into your books. You approve its Economico connection and can revoke that access later.

Is this real accounting, or a spreadsheet with a chatbot on top?

Real double-entry, accrual-shaped books, with a read-only workspace for the recorded activity and reports. Accountant-ready report and ledger exports are planned; review the current reports with your accountant.

Do I need to be a crypto business?

No. Bill and get paid in dollars. Stablecoins are supported for the founders who get paid that way — a capability, not a requirement.

Am I locked in? What if I outgrow it?

You can export the event history and exact source documents in a portable bundle. Practical accountant handoff exports are planned.

Can I actually get in — isn’t this early?

Yes. Every account starts on the Solo plan with the full product for its owner. If you’re a YC founder, your agent can walk you through optional YC verification — one link from bookface.ycombinator.com/verify — and the published YC terms can be included in a separately accepted paid order form.

I run Economico’s own books on Economico. My agents, Claude, Codex and Grok Bot, record the vendor agreements the company runs on, from Anthropic and Cloudflare to GitHub, then post each bill and payment against its agreement with the vendor’s invoice attached. When I want to know what we spend on models and infrastructure, I ask them, then check the entries in the workspace.
