Privacy, quality and clear documentation
European teams tell us they want a partner who treats data protection and quality as the starting point, not an add-on. That is how we work.
GDPR by design
Data minimisation, consent, EU hosting and a signed data processing agreement before any personal data is touched.
Documentation you can audit
Written specifications, architecture notes, test reports and handover documents, so your team or auditors can follow every decision.
Accessible by default
Interfaces built to WCAG guidelines, helping you meet the European Accessibility Act for digital products and services.
Predictable contracts
Fixed scope and price, clear milestones and acceptance criteria, and full ownership of the code and IP.
What we build with LLMs
Custom LLM applications
Assistants, copilots and internal tools built around your workflows, not a generic chat window.
LLM integration
Add GPT, Claude or Gemini to your existing product through secure, well-tested APIs.
Open-source and private models
Deploy Llama and other open models on your own cloud when data must stay in-house.
Fine-tuning and evaluation
Tune models on your examples and measure accuracy with test sets before and after launch.
Guardrails and safety
Input and output filtering, PII masking, grounding checks and human review where needed.
Cost and latency optimisation
Model routing, caching and prompt design that keep responses fast and bills predictable.
How we approach LLM development
Choosing the right model
There is no single best model. We compare OpenAI, Claude, Gemini and open-source options on your real tasks for accuracy, speed, cost and data handling, and design the app so the model can be swapped later without a rewrite.
Grounded in your data
Most business value comes from connecting the model to your documents, databases and tools. We use retrieval (RAG), function calling and agents so answers come from your information and actions happen in your systems.
Built for production, not demos
We add evaluation test sets, logging, monitoring, rate limits, fallbacks and cost alerts from day one, so the app keeps working well after launch and you can see exactly what it is doing.
Security and compliance
Data minimisation, encryption, access control and providers configured not to train on your data. For healthcare we build to HIPAA requirements with BAAs in place for any service that touches PHI.
Built for Stockholm teams
Time-zone overlap
Central European and Indian working days overlap by three and a half to four and a half hours, so your team is online for stand-ups and calls every morning your time.
The GDPR and the Swedish Data Protection Act
We design to the GDPR and Sweden's supplementary Data Protection Act: data minimisation, consent, access controls, encryption, EU hosting and a data processing agreement signed before work starts.
Billing
Invoices in Swedish kronor (SEK), euros or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Industries we work with in Stockholm
Stockholm product companies work with us on SaaS, fintech and mobile apps with clean design, weekly demos and GDPR-aware engineering.
Music, gaming and digital media
Stockholm studios ship global consumer apps. We build AI agents, assistants and automation around these workflows.
Fintech
Near-cashless society expects frictionless digital payments. AI here usually means faster reporting, fewer manual steps and better customer replies.
Automotive and industrial
Manufacturers invest in connected products and electrification. We start with one costly process and automate it end to end.
Cleantech
Green steel and battery projects need data platforms. We build AI agents, assistants and automation around these workflows.
