A go/no-go you can stake your name on.
Fourteen days from kickoff, you have working software in front of real users and the data they generate. Go, no-go, or pivot. You are no longer guessing.
Don't
greenlight the
budget until you
have proof.
A working product, real user data, and a decision you can defend. All in 14 days, at a fixed price.

Normally for this project, you should at least take 18 months. We had the first requirement meeting on the 5th of January and we went live on the 3rd of April.

The problem
You're about to put your name on an untested idea.
The board wants proof.
You believe in the idea, but belief isn't ROI. Without real user data, every budget request feels like a gamble.
Months in. Zero traction.
You have polished wireframes, endless meeting notes, and a growing burn rate, but nothing a real user has actually used.
Top talent is checking out.
Great engineers want to ship, not sit in endless planning cycles. Every month without progress pushes your best people closer to the exit.
Competitors are testing.
While you're still debating scope, someone else is already testing with your customers. The market doesn't wait.
The solution
What changes the moment you have proof.
You don't defend it. The evidence does.
Board, CFO, CTO. They don't want your confidence. They want the data. You bring both.
The downside is capped before you sign.
Fixed price, fixed timeline, fixed scope. The worst-case number is on the table before you sign. Whatever happens during the build, your exposure does not change.
Your guarantees
Every risk you just read about. Eliminated before the build starts.
14 Days, Not Months
A functional product in front of real users while other teams are still debating requirements. You don't just move faster. You know sooner.
Fixed Price Guarantee
Your investment is locked before we write a line of code. Whatever happens on our end, your exposure doesn't change. Any extra time? We cover it.
30 Days Bug-Free
What you ship is what we stand behind. Any bugs in the first 30 days are fixed at no cost. You present it to stakeholders knowing the build is solid.
You have everything you need to make the decision. Your stakeholders don't, yet. Get a working product and the data to defend it, in 14 days at a fixed price.
How it works
Inside the 14 days.
No black box. Four milestones. One go-or-no-go decision.
- 01
Scope locked, in one call.
You hear the plan, push back where it matters, sign off. After that the price doesn't move and neither does the date.
- 02
Built like it's already in production.
Clickable design first, then working software on a production-ready stack. The thing you ship is the thing you scale.
- 03
Watched, not asked.
Five to ten people from your target market run real workflows. We measure what they do, not what they say. The data lands on your desk raw and timestamped.
- 04
A decision you can carry into the room.
Working software, user data, full technical handover. A clear go, no-go, or pivot. You walk into the next meeting with evidence, not opinions.
They didn't take our word for it either.
EasyEnergy needed to detangle from shared infrastructure and migrate their entire customer base to a new ERP without breaking production. Industry baseline: 18 months. We delivered in 13 weeks.
"Most agencies need more managing than they save you. Cermus was the opposite. They told us what they'd do, then did it."
Dennis Huizer, Managing Director, EasyEnergy
We embedded directly into Vattenfall's core product team to accelerate a multi-year delivery roadmap. Simpler tooling, faster releases, fewer manual steps.
"Everything that fell between the cracks at Vattenfall, the problems nobody wanted to touch, ended up with Cermus. And they solved it."
Roberto Heckers, Developer, Vattenfall
