01 / The problem

You already know the answer.
You just don't trust it.

Most big calls — the kind that change your runway, your living room, or your next five years — get made on a mix of gut, a half-finished spreadsheet, and a Reddit thread at 1AM. That's not a strategy. That's a coin flip with extra steps.

— 01 · gut feel

"It just feels right."

Your gut is wonderful at picking restaurants. It is hilariously bad at modeling 5-year cash flow, opportunity cost, and a 7-variable interaction. Sorry.

— 02 · the spreadsheet

The spreadsheet you opened once.

It works! For exactly your friend's situation in 2019. Half the cells are still guesses, half the assumptions are baked in, and nobody else can read it.

— 03 · chat with AI

Confident. Wrong. Convincing.

You ask a chatbot. It writes 800 confident words and invents three numbers along the way. You feel informed. You're not. You decide anyway.

Decisions deserve a better tool than spreadsheets and AI vibes. DDD IQ is here to help.

02 / How it works

Seven steps from "hmm" to "okay, do that."

Each model is a structured decision engine — a set of math and market data that applies to a specific question. You only bring your situation. We do the rest — the market data, the math, and a verdict you can argue with.

01
PICK A MODEL

Choose the question you're stuck on.

Browse a library of decision models across real estate, cars, business, finance, and life. Don't see yours? Add your own — we'll build it.

02
YOUR SITUATION

Tell us about you — not a hypothetical you.

A few precise inputs. Your runway, your city, your hours, your priorities. The fewer assumptions we have to invent, the closer the model gets to your actual life.

THE VERDICT

One answer. With the work shown.

A verdict. The recommended path, a confidence score, and the handful of metrics that actually decided it. Everything else is one click away.

AI STRATEGIST

A second read — in plain English.

The numbers are the answer. The strategist is the context: why this is right for you specifically, what the model can't see, and what you should worry about anyway.

AI Strategist

What this means for your situation

You have 12 months of runway at $5K/mo, which gives you ~$60K to work with. The SaaS path burns ~$750 over 3 months for an MVP, leaving 11+ months of buffer. Consulting starts billing in 3 months with no build cost — but pulls $3.4M behind by year five. The tension is real: consulting pays the rent faster…

 

07
FLIP LOGIC + FEEDBACK

The line where this answer changes.

Every verdict comes with its breaking point. If your runway drops, if your burn climbs, if rates move — the math flips. We tell you exactly when.

⚡ FLIP CONDITION

This shifts to Consulting if your runway drops below 9 months, or your monthly burn exceeds $6,500/mo. Either one collapses the math.

03 / The library

A model for every "should I…"

These are just a sample. More models are added every month. And if yours isn't there yet — propose it. We build the ones our community asks for first.

04 / FAQ

What you are probably asking.

So is this just ChatGPT with a logo?+
No. DDD IQ runs structured decision models — actual math, with named inputs, sourced market data, and a verdict you can trace back to specific numbers. The AI Strategist sits on top of the math, not in place of it. Every figure in your verdict can be edited, and the recommendation updates live.
Where do the market numbers come from?+
For each model we research the key variables that matters — ARPUs, churn, comps, daily rates, mortgage rates, EV incentives — we cite the source and a reference. If our pull is wrong for your situation, edit it. Your edit feeds the math, not the cloud.
What if my decision isn't in the library?+
Click "Add your decision" on the dashboard. Tell us the question, the variables you'd weigh, and what "good" looks like. We prioritize the most-requested models — most go live within a couple of days.
Is it really free?+
Free to sign up, free to explore, and your first decisions are on us. After that, models run on a small points system — buy what you need, when you need it. No subscription required.
Does it tell me what to do?+
It tells you what the math says — and exactly where that answer breaks. Whether you follow it is up to you. The flip-condition card is there so you know which assumption to watch.
Will my inputs be private?+
Yes. Your inputs and decision history are only visible to you. We never sell or share your data, and you can delete your account (and everything attached to it) at any time.
