Economico for YC & accelerator startups

Know your numbers before Demo Day and after

Your next investor question may be about burn, runway or revenue. Keep the underlying activity in real books, then ask your own agent for an answer you can trace.

The spreadsheet scramble is a real founder problem

Founders build their own spreadsheets, pulling metrics from several tools by hand to answer investor questions. The difficult part is not only doing the arithmetic. You have to know which revenue was earned, what cash remains, what a contract commits you to, and what assumptions sit behind runway.

Start the record before the question

Use your own agent to record contracts, invoices, expenses and completed payments in one double-entry ledger. Ask it for MRR, ARR, burn and runway from the activity you have recorded. Inspect the statements, entries and definitions before putting a number in a deck or update. Economico does not write the deck or pull a bank feed for you.

Before the investor call
Show our burn, runway, MRR and ARR. What recorded activity and assumptions produced each number?

Share only what is ready to share

On the Startup plan you can create a revocable link to selected reports and source documents, and add your co-founder with their own role. Review the scope with your co-founder or advisor first; different investors may use different definitions. The record is there for your own decisions, too, long before someone asks for it.

A YC offer, and no fee on your revenue

Every founder gets the full product free on their own, with 100 events a month and no card required. Startup, for cofounders, employees and investors with their own access, is $29 a month or $299 a year per company. Nothing is charged on your revenue, however fast it grows.

YC companies get Startup on better terms. A company that signs up during its batch (Fall 2026: October through December) gets Startup free for 12 months with 10 active share links for investor updates; earlier batches get Startup for $10 a month for 12 calendar months, or $100 for one calendar year paid up front, with 5 active share links. To verify, give your agent a Bookface verification link to submit. See pricing for the terms.

The investor question lands

February runs hot — growth plus a big contractor bill. The answer is ready the moment the question is asked.

An investor asked for our burn — where are we?
