Your competitors are already
moving. You’re still planning.

Every week without a decision is a week of lost ground.

💡

Ideas stay ideas

You have the idea. Maybe even the budget. But without the right team, it never leaves the whiteboard.

Most AI ideas never get built

Competitors move fast

While you’re in meetings discussing feasibility, others are shipping. AI advantages compound quickly.

Speed is the only moat that matters
🔒

AI feels overwhelming

Models, APIs, integration costs, vendors — it’s a maze. Most SMBs don’t know where to start.

Complexity kills momentum
The solution

We build the thing.
You decide if it’s
worth continuing.

ProofWorks builds you a working AI prototype in 2–4 weeks. Not a slide deck. Not a proposal. A real, testable product built by engineers who’ve shipped real software. Then we tell you exactly what it would take to scale — and whether you should.

Clear go / no-go decision
Clarity

Concrete output.
Not vague consulting.

Everything you need to make a confident decision — nothing you don’t.

01

Working Prototype

A functional AI application built for your specific use case. You can use it, test it, and show it to stakeholders.

Real functionality, not a demo
Tested with your actual data
Hosted and accessible
02

MVP-Level Functionality

Not a toy. The POC covers the core workflow end-to-end, so you can validate real usage and spot real problems.

Core use case fully covered
Usable by non-technical teams
Performance benchmarked
03

Business Viability Assessment

We evaluate whether the idea makes business sense — ROI potential, operational fit, and where the real risks are.

Honest evaluation, no sales pitch
Estimated ROI breakdown
Risk assessment included
04

Next-Step Roadmap

A clear path forward. If it works: what scaling looks like and what it costs. If it doesn’t: why, and what to try instead.

Build vs. no-build recommendation

We build fast. Weekly updates. You stay informed without getting in the weeds.

Week 1–4
04
Deliver + decide

You receive the prototype, the assessment, and the roadmap. Make your call with confidence.

End of week 4

Built for real
business problems.

Not theory. Not hype. Just AI that actually does something useful.

⚙️

Process Automation

Replace repetitive manual work with AI that does it faster, cheaper, and without errors. Free your team for work that actually matters.

// VoorbeeldAuto-process incoming invoices,
extract data → ERP → done.
🛠️

Internal AI Tools

Give your team AI-powered tools that fit your actual workflow. Not generic chatbots — purpose-built assistants for your specific job.

// VoorbeeldAI that drafts client proposals
using your tone + past projects.
🔬

Product Idea Validation

Have an idea for an AI-powered product or feature? Test it before spending six figures on full development.

// VoorbeeldAI quality-check tool for
your manufacturing line.

Low entry. High clarity.

The cost of not knowing is always higher than €5.000.

Why €5.000 is obvious.

Compare what you’re risking against what you’re getting. The math isn’t close.

Even if you decide not to build it — you’ve saved months of effort and tens of thousands in development costs. That’s exactly what a POC is for.

Built by engineers
who ship real software.

No fluff. No buzzwords. Just people who know how to build and have the scars to prove it.

We don’t pitch ideas.
We build them.

ProofWorks was started by software engineers who got tired of watching good ideas die in slide decks. We’ve built production systems, shipped real products, and debugged things at 2am. We know what it takes to go from idea to working software — and we do it fast.

AI is our tool, not our identity. We use it where it makes sense, build around it where it doesn’t, and always focus on what actually solves your problem.

📈
Our promise
Speed + clarity + real output
01 — Philosophy

We don’t just talk about ideas. We build them.

Every engagement ends with working software. Not a report. Not a deck. Something you can actually use and test.

02 — Approach

AI is a tool. Clarity is the product.

We use the best available AI where it makes sense. But the outcome we’re delivering isn’t “AI” — it’s a confident, informed business decision.

03 — Standard

If it doesn’t work, we say so.

Our job is to give you the truth. Sometimes that’s a green light. Sometimes it’s “this idea has a fatal flaw.” Either way, you leave with clarity.

🔨

Real builds

Every POC is functional software. We test it with your data, against your constraints.

⏱️

Fast delivery

2–4 weeks, no exceptions. We scope tightly so we can ship fast without cutting corners.

🔍

Honest validation

We’ll tell you if your idea doesn’t work. That’s the point — you pay €5k, not €200k, to find out.

📚

Engineering depth

We’re not prompt engineers or consultants. We’re software engineers who understand systems, data, and scale.

Built different.
On purpose.

🧠

AI-native from day one

We don’t adapt old methods to AI. We build with the latest models, tools, and patterns from the ground up.

Speed is the product

Two weeks of focused work beats six months of planning. We cut scope to what matters and ship.

🎯

Validation, not vanity

We’re not here to impress. We’re here to give you a clear answer — even if that answer is “don’t build this.”

🩹

No BS, full stop

Fixed scope. Fixed timeline. Honest assessment. You know exactly what you’re getting before we start.

Everything you want to know.
Answered honestly.

Our starting price is €5,000 for a fully working prototype delivered in 2–4 weeks. The exact price depends on the complexity of your idea. We discuss this in the first call and give you a fixed price — no surprises.
Just your idea and 45 minutes for an alignment call. We handle everything else: tech choices, tooling, and hosting. If you have your own data we can use, great — but it's not required.
Then we tell you honestly. You get a clear analysis of why it doesn't work and what would work instead. Better to spend €5k finding out than €100k on an idea that doesn't work.
Yes. We work fully remote with no location restrictions. We work in Dutch or English.
You receive the prototype, the viability assessment, and the roadmap. If you decide to build further, we can guide the process or hand it over to your internal team. No obligation.
2 to 4 weeks, depending on complexity. We scope the project to fit that timeline — not the other way around. We'd rather deliver something smaller that really works than something large that's half-finished.
A POC proves whether something is technically feasible — for instance, whether AI can accurately extract data from your invoices. An MVP is a minimal product already serving real users. We deliver a POC with MVP-level core functionality: working well enough to validate whether it's worth scaling, without the overhead of a full product.
We pick the best model for your use case — typically Anthropic Claude for reasoning, OpenAI GPT for multimodal tasks, or open-source alternatives like Llama, Mistral or Qwen when privacy requirements call for it. We're not vendor-locked and always recommend based on what solves your problem best.
Yes. We work under NDA, host the POC on infrastructure you choose (AWS, Azure, GCP or your own environment), and hand over all code and access at the end. For sensitive data, we recommend open-source models running locally or via private endpoints — without data ever going to external AI providers.
Depends on volume and architecture. As a guideline: a production AI application for 100–500 users typically costs €15,000 to €60,000 to develop, plus monthly infrastructure and API costs of €200 to €2,000. The roadmap you receive includes a concrete estimate for your situation.
Yes. We integrate AI functionality into your existing system (CRM, ERP, custom web app) if it has an API or database layer. The POC stays small and focused: prove the AI feature works within your existing context, without rebuilding the whole application.
Good AI cases typically have one of these traits: lots of repetitive cognitive work (reading documents, classifying, summarizing), patterns in data humans can't track anymore, or decisions where consistency matters more than creativity. In the alignment call we'll tell you honestly whether your idea fits — or whether a different type of solution makes more sense.
