We have something to celebrate. Iron Software — the team behind the IronPDF, IronXL, and IronWebScraper libraries used in millions of .NET applications — has named ThreeB IT the Winner of the Excellence In Long-Term Client Partnerships award for 2025.
The certificate landed at Bergstrang 105 signed by Cameron Rimington (Founder & CEO) and Jacob Mellor (CTO). That's high company.
Why this matters to us
ThreeB IT has been building production software on Iron Software libraries since our earliest customer projects — long before "AI-generated PDFs" was a phrase anyone said with a straight face. The award recognises the long-term part of that relationship: years of shipping, not a one-quarter pilot.
Three patterns came up again and again in the partnership:
Speed at moments that matter. Our nationwide COVID testing platform went live in two weeks end-to-end during the pandemic — and the PDF generation feature that anchored it was running within hours of adding the IronPDF NuGet package. You can't fake that kind of velocity; the library just has to work the first time.
GDPR by default. "Because Iron Software doesn't store any data, GDPR compliance is simple. That's critical for every project we build." — Thimo Buchheister, CEO, ThreeB IT. In a country where data-protection sign-off can take longer than the actual implementation, that's a real moat.
Docker-first deployments. The documentation, especially the deployment guides for containers, made hybrid
.NET Framework/.NET Core/ cloud-native shipping smooth from day one.
Where the libraries run today
Across our customer base, Iron Software is the document and spreadsheet layer for:
- Kühne+Nagel — logistics workflows where customs paperwork has to be 100% accurate or the truck doesn't leave the yard.
- National COVID-19 testing infrastructure — certificates, lab reports, and exports against a moving regulatory target.
- Healthcare and fitness SaaS platforms — including our own products Xircuit and Outastory, where every membership invoice and trip log has to render cleanly across every device a customer might open it on.
The interview
Iron Software also asked Thimo to sit down on camera and walk through how we use the stack. The full interview is on the Iron Software YouTube channel:

What's next
We're going to keep doing what got us here: shipping things that have to work the first time, for industries where the cost of a bug isn't a CSS regression — it's a missed flight, a delayed export, or a compliance audit. Iron Software has been part of that story; we expect it to stay part of the next chapter.
"We'll integrate at least one Iron Software product in every future project. It's become part of our standard stack." — Thimo Buchheister
Thank you to the whole Iron Software team. We're proud to be on the wall.
