Big news: First Line Software has been named an OpenAI Select Partner within the OpenAI Partner Network!

We’re working with OpenAI OpenAI to help enterprises design, build, deploy, and scale AI solutions using the OpenAI API and models.

Our focus? AI that goes beyond the pilot stage and delivers measurable business results.

Because a successful AI demo is just the beginning. What matters is how it performs in production.

Meet the people behind the departments 👋

We asked three of our Department Managers three questions about leadership, teamwork, and what they’ve learned from the people around them.

Different experiences, different perspectives — but a lot in common when it comes to building strong teams: listen, communicate openly, make space to grow, and put people first.

Swipe to meet Arslan, Francisco, and Elena and hear their take. 💙

What happens when learning AI becomes a team experience? ⛺️

Over two months, our engineers are building practical AI skills, preparing for Claude Architect Certification, and learning how to apply Claude in real client projects.

But the Camp is about more than certification! Hear from our Department Manager, .vlahovljak Arslan Vlahovljak on how it all turned out!

Learning together. Building together. That’s our kind of camp.

Opticon by Optimizely gave us plenty to talk about — and even more to build on 💚

As an Optimizely Solution Partner since 2010, we’re turning what’s next in CMS, DXP, and AI into real solutions for our clients.

This summer, we launched FLS x Claude™ Architect Camp — a two-month learning journey designed to help every FLS engineer build practical AI skills, prepare for the Claude Architect Certification, and apply Claude by Anthropic confidently in real client projects 🚀

But learning hits differently when it comes from someone who’s already been through it.

Our colleague Petar Markovic, Frontend Developer & Claude Certified Architect, shares his top 5 certification insights — from where to study and how to practice to the mindset that helps when exam answers feel almost equally right.

🏁 Our team is at Ai4 - Artificial Intelligence Conferences , where AI leaders and innovators come together to explore how to turn AI ambition into real-world impact.

And we brought our pit stop idea with us. In Formula 1, a pit stop isn’t a breakdown — it’s where a skilled team quickly identifies what’s slowing the car down, fine-tunes it, and gets it back in the race.

That’s how we approach AI transformation: find the friction, tune what matters, and accelerate forward. From scaling AI to upskilling teams, we help businesses make AI actually work.

Every company working in AI right now sounds the same. Same promises, same buzzwords, same five claims.

So we skipped the script and answered the questions people actually ask us.

💬 A few questions we hear most:
— What does an «AI-Native» engineering company do day to day?
— Why do we run an AI Maturity Assessment instead of selling pilots?
— What happens after go-live, since that is where a lot of AI work quietly starts to drift?

We skipped the scripts and answered your questions about what AI looks like in production.

Watch the full Q&A, and if it lines up with where your organization is, the offer at the end is simple: a straight conversation about what is actually possible.

🚀 We Open-Sourced Our AI Evaluation Framework

Building AI is one thing. Making sure it keeps delivering reliable results after deployment is another.

That’s why we’re open-sourcing eval-ai-library — our AI evaluation framework featuring 15+ metrics for RAG systems and AI agents, developed through real-world production engagements across healthcare, real estate, and digital experience.

This is the framework we use to measure AI quality and reliability in production.
