‍Introduction: AI in Customer Support—A Reality Check

Klarna’s AI-powered customer support has been widely praised for automating 66% of customer inquiries, reducing resolution times from minutes to seconds, and improving operational efficiency. But behind this success is a story of trial, error, and painful lessons.

AI in customer support is often marketed as an instant solution—but as Klarna learned, implementing AI effectively is far from straightforward. Their first attempts at automation led to customer frustration, operational inefficiencies, and poor handoffs to human agents. This post breaks down what Klarna got wrong, how they fixed it, and the key takeaways for companies looking to deploy AI in their own customer service operations.

1. AI Misunderstood Customer Intent—Leading to Wrong Responses

What Went Wrong:

When Klarna first launched its AI-powered customer support, customers quickly became frustrated with irrelevant or incorrect responses. AI could recognize keywords, but it failed to grasp intent, leading to:

• Rigid and unhelpful answers that didn’t fully address customer queries.
• Lack of conversational flow, forcing users to rephrase questions multiple times.
• Misinterpretation of complex inquiries, causing unnecessary escalations.

As a result, customers often had to reach out multiple times to get a proper resolution, increasing workload rather than reducing it.

How Klarna Fixed It:

• Trained AI on real customer conversations, improving its ability to understand intent rather than just matching keywords.
• Implemented context tracking, so AI could reference previous messages instead of treating every inquiry as standalone.
• Introduced confidence scoring—if AI wasn’t certain about an answer, it would escalate the case to a human rather than providing a potentially incorrect response.

🔹 Key Learning: AI needs to process full conversation context, not just keywords, to avoid frustrating customers with irrelevant responses.

2. AI Took on Too Much—And Overcomplicated Customer Support

What Went Wrong:

Klarna initially tried to automate too many types of support requests, including:

• Disputes and fraud-related issues.
• High-stakes financial inquiries requiring human judgment.
• Multi-step interactions that required significant back-and-forth.

The result?

• AI often got stuck, unable to fully resolve issues that required deeper human understanding.
• Customers were forced into long, unproductive conversations with AI before finally being escalated to an agent.
• Support teams became overwhelmed handling escalations that could have been resolved faster had they been routed correctly from the start.

How Klarna Fixed It:

• Restricted AI to handling repetitive, transactional inquiries (e.g., order tracking, refunds, payment reminders).
• Built an AI routing system that detected complexity and transferred difficult cases to human agents sooner.
• Enabled AI to gather information before escalation, so when human agents took over, they had all relevant details.

🔹 Key Learning: Start with AI handling simple, high-volume issues before gradually expanding its scope. Complex cases should be escalated early to prevent AI bottlenecks.

3. AI Sounded Too Robotic—Breaking Customer Trust

What Went Wrong:

Initially, Klarna’s AI responses were:

• Too scripted and mechanical, making customers feel like they were talking to a machine rather than a helpful assistant.
• Lacking empathy, failing to acknowledge customer frustration in cases like delayed refunds.
• Overly formal or rigid, unable to match the conversational style that Klarna’s human agents used.

This impersonal experience led to lower customer satisfaction and a perception that Klarna was prioritizing automation over quality support.

How Klarna Fixed It:

• Trained AI with real customer-agent interactions to mimic a natural conversational tone.
• Implemented sentiment analysis, allowing AI to detect frustration and adjust its tone dynamically.
• Personalized responses, referencing past interactions so AI could respond in a way that felt more tailored and relevant.

🔹 Key Learning: AI should feel helpful and human-like, not robotic. Sentiment analysis and personalization are crucial for AI-driven support.

4. AI-Human Handoffs Were Messy—Causing Customer Frustration

What Went Wrong:

When AI failed to resolve an issue, it didn’t properly hand off conversations to human agents. Customers experienced:

• Having to repeat their problem from scratch after being transferred.
• Longer resolution times, as agents scrambled to get up to speed.
• Confusion about whether they were speaking with AI or a human.

This led to a worse experience than if AI hadn’t been involved at all.

How Klarna Fixed It:

• AI was upgraded to summarize interactions before escalation, ensuring agents had full context before taking over.
• Introduced AI-assisted human support, where AI helps agents by suggesting possible responses and pulling relevant data.
• Made the transition from AI to human seamless and transparent, so customers knew what was happening.

🔹 Key Learning: AI should never create more work for customers or agents. Smooth handoffs with full context are critical to maintaining efficiency.

5. Lack of Transparency About AI Created Customer Confusion

What Went Wrong:

In early versions, Klarna’s AI assistant did not clearly identify itself as AI, leading to:

• Customers assuming they were speaking to a human, resulting in disappointment when responses felt robotic.
• Unrealistic expectations—customers expected AI to have judgment and flexibility like a human agent.
• Loss of trust, as customers felt misled when they eventually realized they weren’t speaking with a real person.

How Klarna Fixed It:

• AI now clearly introduces itself as an AI assistant at the start of conversations.
• Customers are given the option to request a human agent upfront, avoiding unnecessary frustration.
• AI is positioned as a first-line support tool, not a replacement for human agents.

🔹 Key Learning: Always be transparent about AI. Customers should know when they are interacting with AI and should have an easy way to escalate to a human when needed.

Final Takeaways: Klarna’s AI Evolution—Lessons for Customer Support Teams

Klarna’s AI-powered customer support is now a highly efficient, well-integrated system—but only because they recognized and corrected major missteps along the way.

Key Learnings for Customer Support Leaders:

✅ Start Small: Limit AI to simple, repetitive tasks before scaling.
✅ Train AI for Context: AI should understand full conversations, not just keywords.
✅ Make AI Human-Like: Use natural tone and sentiment analysis to improve interactions.
✅ Ensure Seamless AI-Human Handoffs: Customers should never have to repeat themselves.
✅ Be Transparent About AI: Customers should always know when they’re talking to a bot.

By learning from Klarna’s mistakes, companies can avoid the pitfalls of AI automation and deploy AI support the right way—delivering efficiency without sacrificing customer satisfaction.

Klarna proved that AI in customer support isn’t a plug-and-play solution—it requires strategic implementation, ongoing training, and continuous improvement. Are you building AI support the right way? 🚀
