Crafting a Breakthrough Product: A Strategic Narrative

To build a breakthrough product, we must focus on solving a real, painful problem in a way that is radically better—10x easier, cheaper, faster, or more delightful. These kinds of products don’t emerge by accident. They’re the result of deep insight, obsessive motivation, or a unique capability that others don’t possess.

A founding hypothesis is the cornerstone of this process. Like a scientific hypothesis, it makes a clear prediction:

Our customer will choose us over alternatives because we solve a particular problem in a differentiated way.

Each component of this hypothesis—your target customer, the problem you’re solving, and your differentiation—must be tested through small experiments. If it doesn’t hold, revise and iterate. This process begins in the foundation sprint and is validated through back-to-back design sprints to refine, choose the right solution, build it, market it, and ship it.

Competition: Reframing and Redefining

Identifying your competition is about more than just listing players in your category. It must include:

Direct competitors: who offer similar solutions
Indirect competitors: including workarounds, substitutes, or even internal tools
Non-consumption: when people aren’t solving the problem at all

If, during customer interviews, they don’t mention cost, time, or effort when describing their current solution, the problem may not be painful or urgent enough.

Example:

In the video conferencing space, Google Meet was poorly positioned when evaluated on network size or video quality—areas where Zoom and others excelled. But when the competition was reframed along dimensions like ease of use and many-to-one conversation capabilities, Google Meet stood out and found a compelling foothold.

Another example is Slack, which competed not only with other chat tools but also against the dominant system of email. This is what it looks like to position against the most “mighty” competitor by reframing what success looks like.

Differentiation and Strategic Advantage

Differentiation lies at the intersection of:

What customers truly value
What your team can uniquely do

This becomes the core of your strategy. It’s what inspires your team and justifies your product’s existence in a crowded market.

To keep differentiation top-of-mind and actionable, codify it in your company’s operating principles. These principles help guide consistent decisions over time.

Example:

Google used the principle: “Faster is better than slower.”
This embedded speed into their culture and product DNA, ensuring teams prioritized fast, responsive services.

Designing Better Approaches: The Magic Lenses Framework

You should never commit to the first solution idea that comes to mind. Instead, pause and generate multiple alternatives—at least three. This helps explore the solution space thoroughly.

To evaluate these ideas, use the Magic Lenses framework, which consists of evaluating ideas using multiple 2x2 matrices, each offering a different perspective.

Team of Rivals: Diverse Strategic Lenses

Bring in people with differing priorities: - A Product Visionary who cares about experience and quality - A Finance Lead who focuses on margins, costs, and revenue - A Pragmatic Engineer who assesses feasibility and complexity - A Marketing/Growth Expert who considers virality, distribution, and adoption

Each brings a unique lens that helps pressure-test the ideas.

Custom Lenses:

You can also create company-specific lenses. These reflect your differentiators or context.

Example:

If you’re building an app that recommends places to visit, one lens might be a “middle-of-nowhere” perspective—prioritizing utility for users in low-density or underserved areas, rather than optimizing for urban users only.

By checking which idea repeatedly lands in the top-right quadrant (i.e., high feasibility and high value) across multiple lenses, you’re more likely to land on a superior solution.

Experimentation and Iteration

Your founding hypothesis remains just a hypothesis until you prove it. The only way forward is to experiment in tiny loops. Test assumptions quickly. See what resonates with users. Learn. Then iterate.

This approach prevents over-investment in unproven ideas and increases your odds of building something that truly clicks.
