A living model
Every customer, shift and sale is simulated. Watch a day play out hour by hour, from doors open to last orders.
A range, not a guess
300 simulated years turn your assumptions into conservative, expected and optimistic outcomes.
What-if in seconds
Raise prices, add a hire, double marketing or cut rent. Revenue, profit and break-even update instantly.
Honest about uncertainty
Every output is a modeled estimate with visible assumptions — built for exploring a decision, not promising one.
For business ideas, too
Still just an idea? That’s exactly what it’s for.
You don’t need a lease, a business plan or real numbers yet. Pick a business type and Brick Sims fills in typical starting values you can change anytime — so you can see whether an idea holds up before you spend anything on it.
- No business plan or lease needed
- Typical numbers prefilled for your category
- Change any assumption and re-run in seconds

Example using typical category values. A starting point to refine, not a forecast.
How it works
Three steps. About a minute.
01
Describe your business or idea.
Pick a category, add a sentence about the concept, and set the city and size.
02
Set the economics.
Rent, budget, average spend, team, wages, hours and marketing — prefilled with typical values you can edit.
03
Simulate what happens.
365 days of customers, costs and cash — plus hundreds of alternate years to show the range.
Today the simulator runs on your assumptions plus category benchmarks for costs, seasonality and ramp-up. Next, it will layer in market, competitor and location data — so the model starts from what’s actually around your address.

FAQ
Questions, answered.
I only have an idea. Can I still use it?
Yes — that’s who it’s built for. You don’t need a lease, a business plan or real numbers. Pick a business type and Brick Sims prefills typical starting values for rent, staffing, pricing and traffic; replace any of them as your plan firms up.
How accurate is it?
Brick Sims produces modeled estimates, not forecasts. The prototype combines your assumptions with category benchmarks — cost-of-goods ranges, seasonality, ramp-up and capacity — and shows a range of outcomes so you can see which assumptions matter most.
Where do the numbers come from?
From you, first. Typical values are prefilled for each category so you have a starting point, and every one can be edited. Future versions will add market, competitor and location data.
What does the 3D preview show?
A replay of one modeled day: arrivals follow the simulation’s hour-by-hour demand, and each sale is counted as it happens. It’s an early look at where the product is heading — a living model of your business you can watch and tweak.
Is it free?
Yes. The prototype is free with no account. We’re testing interest in a $19 complete analysis, but nothing is for sale yet and no payment is collected.
