How to run a small business on ChatGPT or Claude — without it forgetting everything

By the founders of SECOND FOUNDER · Updated August 20, 2026 · ~6 min read

Most owners use ChatGPT or Claude the way you'd use a very fast intern: ask, get an answer, close the tab. The answer is usually fine. The problem is what happens next Tuesday, when you ask almost the same question and get a slightly different answer — and nothing remembers that you already decided.

This guide is the approach our own two-person product brand, GENIC, uses to run on ChatGPT and Claude (free plans included): treat the AI as an operating partner with a record, not a chat with a genius. It takes about 15 minutes to install and no code.

Why "ChatGPT for small business" usually disappoints

Three failures show up in every owner's story:

• It forgets. Decisions that live only in a conversation were never made. You re-argue pricing in March, June and September.
• It flatters. Ask "should I run 30% off this weekend?" and a default assistant helps you run 30% off this weekend. It doesn't ask what happened the last two times.
• It recites numbers from memory. "Revenue is up" is a feeling. An AI that repeats last month's figure as if it were today's will cheerfully help you spend against it.

None of those are model problems. They're system problems — the AI has no record, no laws about numbers, and no permission to disagree. Fix the system and the same free model behaves like a partner.

The operating-system approach in one picture

Three parts, all of which live inside tools you already have:

1. A constitution. A set of standing instructions pasted once into a ChatGPT Project or Claude Project. It tells the AI how to behave around decisions, numbers and money — every session, without you repeating yourself.
2. A record. A small company record — a Decision Ledger (one sentence, one date, one reopen-condition per decision), open Loops with next-check dates, and Settled facts. Notion works; so does a text file you paste in.
3. A weekly ritual. Sunday, ten minutes: paste six numbers in, get four things back — what moved, what it means together, the anomaly, the one decision.

The 10 laws (the part that changes the AI's behavior)

These are the standing instructions, in plain language. They're the whole difference between a chat and a partner.

What a week looks like

Day 1 (15 minutes). Create a Project, paste the constitution, attach the record. Then the one step everyone skips: write down the five biggest decisions you made this year, with dates. The AI now has priors from week one.

During the week. When a real decision comes up — a discount, a supplier, a hire — the partner surfaces the most similar past decision before it gives a verdict: "You've been here before: Mar 12 you held the bundle instead of discounting, because margin. Here's my call knowing that."

Sunday (10 minutes). The Read:

READ — week of [date]
Revenue: [n] (last week: [n])
Orders: [n] · average value: [n]
Traffic or leads, if known: [n]
Email list: [size] · best send: [open/click]
Ad spend, if any: [n]
Anything that felt weird: [one line]

Back comes: what moved, what it means together, the one number that smells wrong and the cheapest way to check it, and one decision — not five. If you lock it, it goes in the ledger in the same conversation.

Do you need anything connected?

No. The approach runs in manual mode — you paste the numbers you already know, even if they live in a notebook. Connecting Shopify or QuickBooks is a later upgrade, not a requirement. If you can copy and paste, you're qualified.

Build it yourself, or install it

You can build all of this from the table above. Budget an evening for the constitution and two or three weeks of tuning — the failure modes (the AI confirming its own writes, inventing a number to be helpful, softening a verdict) only show up in use.

Or install the one we run. SECOND FOUNDER is the constitution, the Notion record template and the weekly Read, packaged: $99 one-time, 15-minute install, works in the free ChatGPT or Claude you already have, tested on 20 frozen scenarios across both models before we sold it. Our own brand, GENIC, has run on it since April 2026 — 487 decisions on the record. The summer it ran through (three sellouts, a +330% store-revenue month June→July) is ours and dated; the system kept the record, it doesn't claim the credit.

SECOND FOUNDER is a $99 one-time operating-system kit that turns the ChatGPT or Claude a small-business owner already uses into an operating partner: it keeps a dated decision ledger, checks every number before it advises, and runs a ten-minute weekly Read.

Questions

Does this work on the free ChatGPT or Claude plan?

Claude's free plan includes Projects (verified against Anthropic's help docs, Aug 2026), which is where the constitution lives. On ChatGPT, use a Project on whichever plan you have; manual mode works on any plan of either.

Do I need Notion?

No. Notion is the nicest home for the record; manual mode (paste your ledger rows into the chat) works in any AI.

Is this an app or a course?

Neither. It's a one-time system installed into ChatGPT or Claude, plus a small decision record.
