Hey Learners! 📚 They say you learn something new every day, and that’s true.. if you’re a Waivly Learn reader.

It’s that time of the day where you get to learn something brand new or level up your knowledge and skills on a topic you’ve already started to explore.

Today, we’re learning about user retention. Let’s dive in!

The Science of User Retention

Getting people to try your product is one thing. Getting them to stick around? That’s the real challenge. Retention isn’t just a metric—it’s a signal that you’re solving a real problem. Without it, even the most aggressive growth tactics will fizzle out. That’s why the smartest startups obsess over it early.

At its core, user retention is about value and timing. Are users getting value fast enough? Are they coming back because your product becomes more useful over time—or just because you reminded them to? Strong retention loops start with an “aha” moment that shows clear value, followed by a consistent pattern that reinforces it.

There are three key stages to retention: activation, engagement, and habit. Activation is the user’s first win—think “sent my first message” or “uploaded my first doc.” Engagement is what gets them to do it again. And habit? That’s when they stop thinking about it and just do it. Your job is to guide users through all three stages with as little friction as possible.

The AI Report

There’s a reason 400,000 professionals read this daily.

Join 400,000+ professionals at Google, Microsoft, OpenAI, and more who start their day with The AI Report — the #1 B2B AI newsletter. We cut through the noise and show you exactly how to use AI tools to save time, boost productivity, and stay ahead at work.

No hype. No fluff. Just real-world use cases, expert prompts, and actionable tools.

Not all users are equal, though. Segmenting by behavior—rather than just demographics—helps you find your best-fit audience. Who sticks around the longest? Who drops off after Day 1? This isn’t about guessing—it’s about using data to double down on what’s working and fix what’s not.

Retention isn’t just a product problem—it’s a full-team effort. Marketing sets expectations. Onboarding drives the first experience. Support clears the path when things go wrong. The best startups treat retention as a shared metric, not just something for product managers to worry about.

One underrated trick? Make users feel progress. People love seeing streaks, milestones, saved time, or even just a friendly “you’re all caught up.” These small nudges create emotional hooks that build habit and reduce churn.

In the end, great retention isn’t about hacks—it’s about building something people would miss if it disappeared. Make it useful, make it sticky, and above all—make it worth coming back to.

Hey Learners! 📚 They say you learn something new every day, and that’s true.. if you’re a Waivly Learn reader.

It’s that time of the day where you get to learn something brand new or level up your knowledge and skills on a topic you’ve already started to explore.

Today, we’re learning about why AI needs good data. Let’s dive in!

TODAY’S LESSON

^{_{WHERE AI GETS ITS SMARTEST IDEAS}}
Why AI Needs Good Data

If AI is the engine, data is the fuel. And just like you wouldn’t put dirty gas in a sports car, you don’t want to train an AI model on messy, low-quality data. The performance of an AI system—how smart it seems, how accurate its responses are, how useful it becomes—depends almost entirely on the quality of the data it's fed.

Good data doesn’t just mean a lot of it. It means accurate, relevant, unbiased, and well-labeled data. For example, training a facial recognition model on photos that are mostly of one demographic will skew its accuracy. The model might perform well for some people and terribly for others, not because the algorithm is bad—but because its foundation was flawed.

AI systems learn patterns from whatever you give them. If the training data includes typos, gaps, or inconsistencies, the model will internalize that noise. You might end up with a chatbot that confidently answers questions... incorrectly. Or a recommendation system that feels off because it’s drawing from outdated or irrelevant data.

Superhuman AI

This is why data cleaning and curation are just as important as the algorithm itself. Before any AI can be useful in the real world, someone has to make sure the input it’s learning from is solid. That means removing duplicates, standardizing formats, fixing errors, and making sure the data actually reflects the problem it’s trying to solve.

Context also matters. A dataset of restaurant reviews might be great for sentiment analysis—but not if you’re trying to build a voice assistant. The type of data you collect should always match the goal of the model. No matter how advanced the AI, it can’t compensate for input that doesn’t make sense.

At the end of the day, the saying “garbage in, garbage out” has never been more true. The smarter AI gets, the more important good data becomes. Want AI that feels truly intelligent? Start by feeding it something worth learning from.
