Service Overview

AI Agent Development Solutions for Stockholm Businesses

Stockholm has produced two of the most publicly documented AI agent deployments in Europe. Klarna's OpenAI-powered customer service assistant, launched in 2024, handled the equivalent workload of 700 full-time agents within its first month and resolved 2.3 million chats in 23 languages with reported satisfaction parity to human agents. Spotify's AI DJ, built on the Sonatic acquisition and OpenAI generative voice, personalises listening for hundreds of millions of users. Ericsson runs agentic systems across 5G network management out of Kista Science City, SEB's chatbot Aida was one of the first European banking assistants in production, and Truecaller deploys ML agents for call screening at planetary scale. Codazz builds production AI agents for Stockholm fintech, gaming, telco, retail, and B2B SaaS teams operating in this same arena. We ship multi-step agents on OpenAI Assistants, Anthropic Claude with tool use, and LangGraph, deploy retrieval and tool-using agents through AWS Bedrock and Azure OpenAI in Sweden Central, and ground every build in EU AI Act risk classification, GDPR oversight by the Swedish authority IMY, and Finansinspektionen rules where banking or insurance is in scope. Our New York morning and Chandigarh evening hubs deliver fixed-fee builds with model cards, evaluation harnesses, and incident playbooks Stockholm risk and procurement teams can sign off without a second vendor.

What We Build

AI Agent Development Services We Offer in Stockholm

Stockholm enterprises buy AI agents to do real work, not to produce demo videos. Klarna's deployment displaced a measurable cost line and the company published the operating numbers, which has reset local expectations. Our agent services follow that bar. We build customer service and support agents on OpenAI Assistants, Claude tool use, and LangGraph with full conversation logging and human handoff; sales and revenue agents that draft follow-ups, qualify leads, and update Salesforce or HubSpot; internal copilots for legal, finance, and procurement with retrieval over SharePoint, Confluence, and Google Drive; and operational agents for incident triage, log analysis, and ITSM workflows. Every agent ships with an evaluation harness, prompt injection defences (input validation, system prompt protection, output filtering), and a documented EU AI Act risk classification.

⚙️

Task Automation Agents

Agents that run entire back-office workflows end to end — invoice processing, cross-system reconciliation, email triage, recurring reporting. Unlike RPA scripts that shatter when a field moves, these work from the goal and adapt to the interface they find, escalating the cases they are not confident about instead of failing silently.

Customer Support Agents

Support agents that resolve rather than deflect — authenticating the customer, pulling live order and subscription data, issuing refunds inside your policy limits, and closing the ticket. Complex cases transfer to your team with the full context already gathered so nobody has to repeat themselves.

Multi-Agent Systems

Teams of specialist agents coordinated by a supervisor that decomposes the goal, routes each sub-task, and verifies the result before accepting it. Built with typed contracts between agents, hard iteration and spend limits, and full replayable traces — so a wrong answer is debuggable instead of mysterious.

RAG & Knowledge Agents

Agents grounded in your own documents, with permission-aware retrieval that respects who is asking, iterative multi-hop search that reformulates when results are weak, and citations on every claim so a reviewer can verify in one click instead of trusting the model.

Industry Expertise

AI Agent Development for Stockholm's Key Industries

Three Stockholm verticals dominate our agent pipeline. Fintech is first: Klarna has set the public benchmark, but every Swedish bank and BNPL has internal projects in flight. We have shipped support agents, document extraction agents for KYC and AML, and internal copilots for compliance research under Finansinspektionen, EU Consumer Credit Directive, and EBA Guidelines on Outsourcing. Gaming is second: King, Mojang, Avalanche, Paradox, and Embark increasingly use agents for community moderation, player support, and live-ops content generation, with COPPA and EU DSA obligations where minors interact. Telco and B2B is third: Ericsson and Telia run agents for network operations, ITSM, and customer self-service, while Stockholm B2B SaaS (Mentimeter, Tobii, Sinch, Hemnet) deploy revenue and onboarding agents. We have shipped in all three.

Our Process

Our AI Agent Development Development Process

We run a five-week build cycle that maps to Stockholm enterprise governance. Week 1 is discovery: agent scope, EU AI Act classification (most customer service agents are limited-risk; HR and credit are high-risk), GDPR data inventory under IMY rules, and a tool inventory mapping every external API the agent will call. Week 2 to 3 is build: prompt engineering, retrieval pipeline if applicable, tool schemas, and an evaluation harness with at least 100 test cases reviewed by the client. Week 4 is hardening: red team for prompt injection, rate limit and cost guardrails, monitoring on Langfuse, Helicone, or Arize, and human handoff design. Week 5 is shadow deployment, A/B testing against existing flows, and gradual rollout with rollback. Weekly standups run 10:00 CET. All pricing is fixed-fee in SEK with milestone deliverables.

Technologies We Use for AI Agent Development

Default LLM choice for Stockholm clients depends on data residency and EU AI Act posture. For high-risk or sensitive workloads we use Azure OpenAI in Sweden Central (Gävle) or Sweden South (Sandviken), AWS Bedrock with Claude in eu-central-1 (Frankfurt, no Bedrock in Stockholm yet), or self-hosted Llama 3, Mistral, and Qwen on GPU clusters in AWS eu-north-1 (Stockholm). For lower-risk consumer agents we use OpenAI or Anthropic APIs directly with EU data processing addenda. Orchestration runs on LangGraph, LlamaIndex, or custom Python on FastAPI behind Cloudflare Workers. Vector storage on pgvector (Postgres), Weaviate, or Pinecone with EU residency. Observability on Langfuse (open source, self-hostable in Stockholm), Helicone, or Arize. Evaluation through Promptfoo, Ragas, and DeepEval, with red-team suites for prompt injection and jailbreak resistance.

Why Choose Us

Why Stockholm Businesses Choose Codazz for AI Agent Development

We combine world-class engineering with local market understanding to deliver ai agent development solutions that drive real business outcomes.

🤖

Klarna-Pattern Agent Builds

Klarna's OpenAI assistant handled 2.3M chats and the workload of 700 agents in its first month, the most public European deployment to date. We study that architecture and replicate it at Stockholm SMB and mid-market scale, targeting realistic 40 to 60 percent deflection within six months.

📜

EU AI Act Documentation

Every agent ships with a written EU AI Act risk classification, Annex IV technical documentation when high-risk, GDPR DPIA, and a Schrems II transfer impact assessment. Stockholm-listed companies (Klarna, Avanza, Sinch) face the strictest scrutiny and our documentation is built for that bar.

🛡️

Prompt Injection Hardened

Four-layer defence — input validation, structured tool schemas, output filtering with LLM referee, and a 100-plus case adversarial evaluation harness re-run after every prompt change. We red-team every agent before production using known jailbreaks (DAN, Crescendo, indirect injection).

🇸🇪

Sweden Central Data Residency

Azure OpenAI in Sweden Central (Gävle) and Sweden South (Sandviken), AWS eu-north-1 self-hosting for Llama 3 and Mistral, pgvector and Weaviate in EU regions, Langfuse self-hosted in Stockholm. No cross-border transfer when Finansinspektionen, IMY, or DORA scope demands EU residency.

Frequently Asked Questions About AI Agent Development in Stockholm

Have a question not listed here? Reach out to our team and we will get back to you within 4 hours.

Ask a Question

The number follows what you actually build: a scoped production agent (customer support, internal copilot, document extraction), larger multi-agent systems with custom tool ecosystems, complex orchestration, and EU AI Act high-risk documentation, or ongoing optimisation, prompt iteration, and evaluation maintenance. Scope drivers include discovery, build, evaluation harness, red team, monitoring, and shadow deployment.

The EU AI Act came fully into force across 2025 to 2027, and Stockholm enterprises (especially the Klarna, SEB, Ericsson tier) are running classification audits across their entire AI estate. Our discovery phase produces a written EU AI Act classification per agent. Customer service and information retrieval agents are typically limited-risk, requiring transparency obligations only (the user must know they are interacting with AI). Agents touching credit decisioning, hiring, education access, biometric ID, or critical infrastructure are high-risk and require conformity assessment, technical documentation, risk management system, data governance, human oversight, accuracy and robustness controls, and CE-mark equivalent registration. We deliver the technical documentation pack aligned with Annex IV when high-risk; legal sign-off and notified body engagement remain with your in-house counsel.

Yes, and we deliberately study the Klarna deployment because it is one of the few European agent projects with published operating numbers (2.3M chats in first month, 700 FTE equivalent, 25 percent faster resolution, parity CSAT). The architecture is well-understood: an OpenAI-based assistant with retrieval over the Klarna knowledge base, tool calls into Klarna's order, payment, and refund systems, multilingual support (23 languages, mostly through native model capability), and human handoff for complex cases. We replicate that pattern at Stockholm SMB and mid-market scale using OpenAI Assistants or Claude with tool use, a smaller retrieval corpus (typically 5,000 to 50,000 documents), and integrations with Zendesk, Intercom, or Front. Realistic Stockholm SMB results are 40 to 60 percent contact deflection in first six months, with CSAT within 5 points of human baseline.

Stockholm's data protection authority IMY (Integritetsskyddsmyndigheten) has been one of the more active GDPR enforcers in the EU, with rulings against Klarna, Spotify, and Tele2 on consent, access requests, and data minimisation. Our agent builds include a written Data Protection Impact Assessment (DPIA) before any personal data flows into the LLM, a documented lawful basis (usually legitimate interest for B2B, consent for sensitive B2C), retention limits enforced at the storage layer (pgvector or Pinecone TTLs), and a Right to Erasure pipeline that purges both vector embeddings and conversation logs on request. We also document Schrems II transfer impact assessments for any non-EU model provider, and prefer Azure Sweden Central or self-hosted models when sensitive PII is in scope to avoid cross-border transfer entirely.

Stockholm gaming studios (King, Mojang, Paradox, Avalanche, Embark) typically deal with multilingual player support at huge volume, in-game purchase and refund disputes, abuse and toxicity reports, COPPA-aligned minor protection, and live-ops content questions. Our gaming agents are built on Claude or GPT-4o with tool use into Helpshift, Zendesk, or AppsFlyer for player lookup, refund APIs, and ban-list services. Retrieval covers patch notes, FAQ, and known issue databases. We hard-code EU DSA obligations (clear reporting and appeal mechanisms), COPPA protections (no PII retention from confirmed-minor users, automatic human escalation), and Apple and Google app store dispute timelines. Deflection in production runs 50 to 70 percent on common L1 tickets, with the agent handing off cleanly to human support for refund decisions above a threshold.

Yes. Klarna, Trustly, Avanza, Nordnet, SEB, Handelsbanken, and Swedbank all operate under Finansinspektionen (FI) supervision, with overlapping rules from EBA Guidelines on Outsourcing, DORA (the EU Digital Operational Resilience Act, fully applicable since January 2025), the EU Consumer Credit Directive, and PSD2. Our fintech agents stay inside EU regions (Azure Sweden Central or self-hosted Mistral in eu-north-1), produce DORA-aligned ICT third-party risk documentation, ship with the technical resilience and incident reporting controls FI inspectors expect, and document EBA outsourcing notifications when the agent qualifies as a critical or important function. Output logging feeds existing SIEM and model risk management platforms. We have shipped under these constraints and welcome FI inspection-readiness reviews as part of scope.

Prompt injection is now the OWASP LLM Top 10 number one risk and has caused public incidents at Stockholm-relevant peers (the DPD chatbot incident, the Air Canada hallucination case, the Chevrolet of Watsonville $1 truck case). Our defence stack runs in four layers: input validation and PII redaction before the prompt reaches the model, system prompt isolation with structured tool schemas (Claude tool use and OpenAI function calling rather than string-based prompting), output filtering with both regex and a smaller LLM acting as a referee, and a behavioural evaluation harness with at least 100 adversarial test cases including known jailbreaks (DAN variants, Crescendo, prompt leaking, indirect injection via retrieved documents). We red-team every agent before production and re-run the harness after every prompt or model change.

Yes. Stockholm enterprise stacks tend to standardise around Microsoft 365 (Teams, SharePoint, Azure AD), Salesforce or HubSpot for CRM, ServiceNow or Jira for ITSM, SAP or Visma for ERP and finance, and either Workday or BambooHR for HR. Our agents integrate through documented connectors (Microsoft Graph, Salesforce APIs, ServiceNow Table API, Jira REST, SAP OData) with proper OAuth scoping and least-privilege service accounts. For Klarna and Spotify-style operations we have built custom tool layers against internal microservices, with mTLS and short-lived JWT auth. Tool schemas are versioned and tested, every tool call is logged with input, output, latency, and cost, and we provide a runbook for tool failures that distinguishes between agent error, integration error, and downstream system error so on-call engineers can triage in under two minutes.
