Product foundations: What to build in your first 60-90 days

By Zofwe

You have an idea. Maybe it’s fully formed, maybe it’s just a feeling that something should exist. Either way, you need to turn it into something real. But where do you start? What do you build first? How do you avoid building too much or too little?

Product foundations is about answering these questions and building the first version of your product, the one that proves the idea works and sets you up for growth.

What are product foundations?

Product foundations are the essential pieces you need to launch and learn. They’re not everything your product will eventually become. They’re the minimum set of features that let you:

  • Validate your core idea
  • Get real users and feedback
  • Learn what actually matters
  • Build on a solid base

Think of it as building the foundation of a house. You don’t build all the rooms first. You build the foundation that everything else will sit on.

Why 60-90 days?

Sixty to ninety days is enough time to build something meaningful but short enough to force hard decisions. It’s long enough to build real features but short enough that you can’t procrastinate on hard choices.

This timeline forces you to focus on what matters most. You can’t build everything, so you have to choose. That’s good. Choosing forces clarity.

Step 1: Define your core value

Before you build anything, answer this: What’s the one thing your product does that makes it worth using?

Not three things. Not five things. One thing. If you can’t explain it in one sentence, you’re not ready to build.

Your core value should be:

  • Specific: Not “helps people learn” but “helps students practice math problems with instant feedback”
  • Valuable: Something people actually want, not just something you think is cool
  • Testable: You can tell if it’s working

Everything else can wait. If your core value doesn’t work, nothing else matters.

Step 2: Identify your essential features

Once you know your core value, identify the minimum features needed to deliver it. Not the nice-to-haves. Not the “wouldn’t it be cool if” features. Just what’s essential.

For each feature, ask: Can we launch without this? If the answer is yes, it’s not essential.

A good way to think about it: What’s the smallest version of this product that someone would actually use? Build that.

Step 3: Define your user flows

Map out how someone goes from discovering your product to getting value from it. Keep it simple. Three to five steps maximum.

For each step, ask:

  • What does the user need to do?
  • What information do they need?
  • What happens if something goes wrong?

Don’t design every edge case. Design the happy path first. You can handle edge cases later.

Step 4: Choose your tech stack

Your tech stack should be:

  • Familiar: Use technology your team knows or can learn quickly
  • Stable: Choose tools that will still be around in a year
  • Appropriate: Match the tool to the problem, not the trend

Don’t choose technology because it’s trendy. Choose it because it solves your problem and your team can work with it effectively.

For most products, you don’t need the latest framework. You need something that works and that you can maintain.

Step 5: Plan your first release

Your first release should be:

  • Small: Just enough to validate your core value
  • Complete: It should work end-to-end, even if it’s simple
  • Launchable: Real people can use it, even if it’s just a few

Don’t wait for perfection. Launch when you have something that works and provides value. You’ll learn more from real users than from perfecting in isolation.

Common mistakes

Building too much: Trying to include every feature you can imagine. Focus on your core value.

Building too little: Building something so minimal it’s not useful. Find the balance between minimal and valuable.

Waiting for perfection: Perfection is the enemy of launch. Ship something that works, then improve it.

Ignoring feedback: You built it to learn. Listen to what users tell you.

Not planning for growth: Build systems that can evolve, even if they’re simple now.

What comes after foundations?

Once you’ve launched and learned, you can:

  • Add features based on real feedback
  • Improve what’s working
  • Remove what’s not
  • Scale what matters

Your foundations should make this easy. If adding new features requires rewriting everything, your foundations weren’t solid enough.
