About us
We build and operate AI-native systems end to end, with deep expertise in real estate, healthcare, and digital experience.
More than 15 years of shipping production software across industries means we know the integration landmines,
the compliance requirements, and what it takes to run AI in production at scale.
Three primary offerings.
One engineering foundation
Level 1
NoviceYou have no AI governance, but your people are already using AI on their own, unmanaged. Your IT team knows it and doesn’t have a plan.
Where we’d start:
AI Skills Enablement — Soft Landing Program
Best for
- Claude Enterprise deployed, but barely
used - AI work currently siloed
Business value
- NDA review: 4 hours → 45 minutes
- Every specialist shares the same methods
- New hires get the workflows from their first day
Time to value
- 6–12 weeks · First live files on day one
Level 2
IntermediateYou’ve already piloted AI as a chatbot, internal tool, or proof of concept. But now it’s stalled. Nobody manages it end to end.
Where we’d start:
Managed AI Services
MAIS®
Best for
- AI is in production & oversight is the bottleneck
- Reliability matters more than speed
Business value
- Less manual effort, lower run cost
- Lower operational, security, and regulatory risk
- Predictable, KPI-driven outcomes
Time to value
- Ongoing — compounds as systems mature
Level 3
AdvancedYour engineering team already ships with AI tools. Now, you need discipline and predictability.
Where we’d start:
AI SDLC Adoption — RACE Programming
Best for
- Leadership needs ROI for the AI spend
- Licensed seats active, but adoption plateaued
Business value
- Reduce operational cost and manual effort
- Embed AI into core business workflows
- Achieve measurable, KPI-driven impact
Time to value
- 8–12 weeks · Baseline vs. after, week 9–10
Two speeds for building
Best for
- Problem-solving sprints, innovation initiatives, new product directions
What you get
≈10x velocity
• Expedited Product Development
• Production-ready solution
Business value
- Ships in days, not months
- Outcome-driven without you having to manage engineers
- A small AI-powered team of 3 replaces the traditional team of 9
AI-Accelerated Engineering
AI-Native Engineering at Scale
From initial system to enterprise-grade production — in as early as weeks
Best for
- Developing products, core platforms, scaling engineering teams
What you get
≈3x velocity
Engineering throughput with AI-native teams
Business value
- FLS brings the AI toolbelt and methodology
- Your team brings domain context and codecase
- We ship inside your release cadence and compliance posture
Two ways in: for legacy rewrites and SaaS replacement
Re-Engineer
Your critical business logic is locked in legacy code that agents can’t reach. We extract it (Code → Intent), then either rebuild it cleanly or enhance what you have.
Best for: systems no one fully understands, vendor lock-in, agentic AI readiness.
SaaS Exit
You’re paying full price for a SaaS platform and using 20-30% of it. We extract what you actually use and rebuild it as something you own.
Best for: enterprises overpaying for underused platforms, CFO–CTO alignment on OpEx reduction.
Awards & certifications
Our Partnership begins with trust
They are very good at understanding the requirements but more importantly they can think about the future requirements and future proof your project.
Qi Li
Physician Executive, Product Development At Intersystems
First Line Software has a large team, and because of the breadth of services, they can give you that flexibility to work on other projects. Adding another technology to your stack, for example, is one way they could support you.
Jay Thomas
Chief Strategy Officer, Triptych, USA
Deep industry knowledge and expertise, even in somewhat esoteric areas.
They were willing to go above and beyond to help clients in any and every way possible.
CEO, Modern Trials
The result is faster, with more consistent outcomes and reduced costs. We can capture and scale critical expertise, turning decision-making into a repeatable system that can be applied across domains.
Collin Sedmak
Founder, Heuritex
I’ve worked with other developers, but I found that the First Line Team is very knowledgeable and helpful. I would totally recommend them to anyone who’s looking into their services.
Technology Project Manager,

Why most enterprise AI stalls — and how we operate differently
Agents sit next to the work, not in it
People have to switch tools to use them, so they don’t. The agent’s data is a stale export, so its answers drift. Value never compounds.
Governance never gets a yes
CISO, Legal, and Compliance aren’t blocking AI because they dislike innovation. They’re blocking it because nobody gave them the controls they need to approve it.
Data goes stale
Most AI runs on snapshots. We connect to live systems of record, so outputs stay accurate.
Engineering that holds in production
AI isn’t a demo — it’s a system. We build scalable, reliable, maintainable solutions that perform under real-world constraints.
Claude Certified Architects on every engagement
The people writing your code hold Claude Certified Architect credentials from Anthropic — they know how these models reason, fail, and scale before the first line is written.
Take the next step
Bring your AI idea – we’ll help you scope it.
We’ll help clarify the use case, define success metrics, and outline a realistic first step.

FAQ
What allows you to ship AI solutions so quickly?
We leverage nine reusable AI components (RAIC). Our RAIC library is built to expedite approvals:
– Evaluation Tool gets CISO sign-off
– Quality Control clears Legal,
– Data Grounding Agent passes your CTO’s architecture review
– AI Search satisfies your DPO
– Prompt Management gives Audit its trail.
We don’t just move faster — we arrive with the evidence enterprise governance actually requires.
How do we get our teams to actually use the AI once it’s built?
We solve this at the architecture level with FLS Claw, our agentic mesh. Our agents live where your people already work: Slack, Microsoft Teams, WhatsApp. There’s no new tool to learn, no new habit to build, no friction between asking a question and getting an answer. Claw runs inside isolated cloud containers with zero-trust credential handling and prompt-injection defense built in, and connects via MCP to your systems of record so agents reason on live data, not stale exports. This is how AI stops being an app nobody opens and becomes part of how the work gets done.
What if the solution we need isn’t AI?
No problem! We may leverage AI in our engineering process, even for non-AI software solutions. We meet you exactly where you are, and leverage our top talent and technology to solve your problems.
Which industries does First Line Software support?
We go deep in real estate, healthcare, and digital experience — and we’ve shipped hundreds of systems across financial services, manufacturing, and other enterprise environments over 15 years. When you come to us in our depth domains, you get domain knowledge from day one. When you come to us elsewhere, you get engineering fundamentals that travel.
What’s the benefit of using a custom software firm versus an off-the-shelf AI product?
Product vendors ask “does your workflow fit our feature set?” We ask “what’s actually broken, and what would it take to fix it?” We don’t have a product to sell you — we build what solves your problem, inside your environment, owned by you. Off-the-shelf tools create invisible ceilings the moment your workflow diverges from the vendor’s assumptions. Ownership of the data, the model, and the IP is increasingly the differentiator.
Do you replace internal teams?
No — we amplify them. In RACE Mode we ship outcomes without touching your team. In AI-Accelerated Engineering we work shoulder-to-shoulder with your analysts and leaders so they leave the engagement faster than they entered it.
Which countries does First Line Software operate in?
First Line Software delivers exclusively from its entities in the Czech Republic, Poland, Germany, the Netherlands, Slovakia, Montenegro, the United Kingdom, Australia, and the United States.
First Line Software ceased all business operations in Russia effective 15 April 2022, following a strategic review completed in March 2022. As part of that decision, our Notice Regarding firstlinesoftware.ru — First Line Software brand, and ownership. Since that date the company has had no legal entity, no offices, no delivery centres and no personnel in the Russian Federation.
