Why 400?

From Earth, the Sun and Moon appear the same size. They are not.

The Sun is 400 times larger than the Moon. But also 400 times farther away. Size on one side. Distance on the other. 400 to 400. That is why, during a solar eclipse, they align exactly.

Not a myth. Not a marketing invention. An observable relationship that turns difference into equilibrium.

That is what Faktor400 stands for: making relationships visible instead of staring at isolated numbers.

What does this have to do with your business?

For Amazon sellers, balance is not abstract. It shapes margin, cash flow, and growth every day.

Revenue alone is not enough. What matters is what remains after fees, PPC, returns, shipping, and cost of goods.

Growth alone is not enough either. If inventory, demand, and capital drift apart, growth quickly turns into pressure.

More ads are not automatically better. More data is not automatically better either. The relationship is what matters.

That is where we want to help: not with more dashboards, but with clarity about what is connected, what is drifting, and what matters next.

It's all about balance, isn't it? Your bank. Your decisions. Your direction. The Sun and Moon look equally large because 400× in size meets 400× in distance. Cosmic balance. Faktor400.

What we build

Faktor400 is a business analytics platform for Amazon sellers. 8 engines run in the background, analyzing your data around the clock and delivering:

  • Real numbers. 15+ cost components — from FBA fees to advertising costs. Your true profit, not an estimate.
  • Clear forecasts. Inventory predictions, revenue trends, cash flow scenarios — before you ask.
  • Concrete actions. Not "something could be better", but "raise this price", "reorder this product", "pause this campaign".

TrueProfit shows what is actually left. SmartForecast shows where your month is likely to end. AdOptimizer, RestockIQ, CashflowEngine, VisibilityTracker, CustomerIQ, and FeeEngine handle the relationships that usually get lost in day-to-day operations.

What you can expect from us

Numbers before claims.

If we call something important, it should be visible, measurable, or traceable.

Clarity before complexity.

Amazon is complex enough. The product does not need to add more noise.

Action before decoration.

A report is only useful if it tells you what to do next. Answers, not homework.

  • No AI buzzwords. Our engines are built logic with concrete outputs.
  • No feature gating. All 8 engines in every plan.
  • No data sharing. Period.

Built by sellers. In Germany.

Faktor400 is not a VC-funded experiment. It is the platform we wished we had as Amazon sellers — and eventually built ourselves. Every engine solves a problem we know from firsthand experience.

Built in Germany. German servers. GDPR-compliant. Your data never leaves the EU.

See the balance. Decide better.
