Inferior solutions are winning
because their proof is
stronger than yours.

For the early-stage founder

You have two or three customers who love what you do. None of it has been written down yet.

For the growth-stage founder

A competitor with a worse solution is winning deals you should win. They provided better proof.

For the marketing leader

Your team is producing proof assets. The sales team is not using them.

For the VP / CMO

Your proof programme exists on paper. In practice it is three customers and a Google Drive folder.

A PROOF PROGRAM
THAT ACTUALLY RUNS.

a proof program that actually runs

Most companies treat proof as a production task. Brief an agency. Chase a customer for a quote. Publish the PDF. Move on. Six months later the same five assets are sitting in the same folder and sales is still using none of them.

The problem is not the assets. It is everything around them. How proof gets captured, structured, activated, and kept current as the company grows. Without that infrastructure, every case study is a one-off.

With it, every new customer win compounds on the last.


Why I started 3DGE.

I’m Bart Kalmeijer, the founder of 3DGE.

After ten years working in marketing, the same problem showed up everywhere. Great work, happy customers, and almost none of it captured in a way that worked in the sales process.

The proof existed. In customer conversations nobody transcribed. In reviews on Capterra and G2, In NPS scores. In results that had never been written down.

The infrastructure to turn it into something that closed deals simply did not exist.

I built 3DGE to create that infrastructure. Not just better case studies. A proof program. One that runs, compounds, and keeps working as the company grows.

"Bart from 3DGE turned complex IT/cloud concepts into compelling content that drove real engagement. His work on case studies consistently elevated our B2B campaigns."

Frequently Asked Questions

Got Questions? We've Got Answers!

We only have a handful of customers. Is it too early for a proof program?

We have tried case studies before. They sat in a folder and sales never used them.

Our customers are in regulated industries. They cannot go on the record.

How is a proof programme different from hiring a case study writer or briefing a content agency?

How much time will this require from our team and how long before we see results?

What does working with 3DGE actually look like day to day?

What if we only need one or two case studies rather than a full program?
