No Idea What to Build Next? Let Customer Complaints Talk

Feeling stuck? Not sure what you should work on next?
Is it time to build your product roadmap, but you only have a few eggs in one basket?

Ok, I got you.

We are product people, and our job is simple (but not easy): solve customer problems.
The real question is—how do you reliably identify those problems?

There’s one place you should always start.

Customer Support.🙌

They know your customers better than anyone else. They talk to them every single day. They hear the frustrations, the confusion, the anger, and the unmet expectations. Go sit with them. Talk to them. And most importantly, get access to their support tickets or complaints database.

That’s the Holy Grail.💥
There’s nothing more valuable than a well-maintained complaints database.

From Manual Pain to AI Superpower

Back in the day—before large language models were widely available—you had to manually go through this data. Teams relied on NLP pipelines, sentiment analysis, and keyword clustering to understand complaint context and categorize issues.

Best case?
It would take at least a week.💀

And as a product manager, you were lucky if someone on your team even had that skill set.

Fast forward to 2026.

ChatGPT, Gemini, Claude—and other AI tools—are now part of our everyday workflow.

Turning Complaints Into Insights (Fast)

Today, the process is dramatically simpler.

Make sure you’re using a paid, enterprise-safe AI solution
Ensure you’re not exposing sensitive company or customer data
Load the complaints data
Ask the right questions

👉For example:

“Here is a sheet of customer complaints in Greek, written in free text.I want you to extract key customer problems. Provide 10 main customer pain points. If some complaints cannot be categorized, place them in a group called ‘Other’. Include the number of customers per category.”

👉Then, follow up:

“Provide a deeper dive into the first category. Focus on issues related to money withdrawal. List the key issues and the number of customers reporting similar complaints.”

And then… keep going.

Drill deeper. Ask why. Look for patterns. Compare volumes. Identify trends over time.

From Chaos to Roadmap—In About an Hour

In roughly an hour, you’ll have:

Clear customer pain points
Quantified impact
Strong signals for prioritization
Solid input for your roadmap discussions

What used to take days—or weeks—now takes minutes.

Life didn’t just get easier. Product discovery got smarter.

Bridging the Gap: Guiding Stakeholders into the Age of AI

Bridging the gap: Guiding stakeholders into the age of AI Transitioning to the AI era isn’t always easy—especially in more traditional, old-fashioned industries. People are often reluctant to change or may believe that “if something works, why bother fixing it?” But the product lifecycle tells another story. At some point, every product will need a drastic revamp, a re-introduction to the market, or a complete phase-out. Let me walk you through my journey, and then we’ll dive into the practical aspects—which are, honestly, much more interesting! Who Am I? 👋 Hi folks! I'm Danai Aristeridou—a Product girl who landed (somewhat organically) in AI product management from a data science (DS) background. I still remember my early days in a hands-on DS role. Stakeholders struggled to understand what we were doing. There was a lack of trust and a need for control. We had to educate them, build understanding step-by-step, and iteratively move toward our goals. It wasn’t always smooth, but...

Common mistakes in product discovery sessions

What I enjoy most about the role of a Product Owner is product discovery. Many of these sessions have ended in failure 😓—but looking back, I now see those failures as invaluable. Connecting the dots helped me realize that each misstep carried a lesson. Out of these experiences, I’d like to share the most common mistakes I made (and I believe many newbies do too). Leading by example in reverse ! 💀 Using discovery sessions for validation: Let me explain by using a story. When I go to yoga, my lovely instructor always says "Use your mind like a beginner. Approach each position as if you’re experiencing it for the first time." . In Greek it's called the αρχάριος νους. Αccording to Shunryu Suzuki: In the beginner's mind there are many possibilities, but in the expert's mind there are few. I try to bring this principle into discovery sessions today—but it wasn’t always the case. In my early days, I’d tal...
