Why Problem Interviews Matter More Than Technical Founders Think
Technical founders skip problem interviews more than any other kind. The reason is structural. They can build, so they reach for the build. They can solve hard problems with code, so they assume the problem they cannot solve with code is also a coding problem.
It is not. The problem of figuring out what to build is a conversation problem. And that mismatch is why technical founders, despite being absurdly capable, ship products nobody wants more often than they should.
The Specific Trap for Technical Founders
If you are technical, your default response to ambiguity is to start building. Building feels productive because it produces visible artifacts. You can show a co-founder, a friend, an investor. You feel competent during the building.
The interview round produces no visible artifacts. It is just notes in a doc. For a technical founder, that feels like the wrong kind of work. Soft, vague, unverifiable. Easier to dismiss in favor of one more sprint.
What You Are Missing By Defaulting to Build
Code answers the question, "can this be built." Interviews answer the question, "should this be built." They are different questions and they require different methods.
Technical founders frequently nail "can" and miss "should." The result is a beautifully engineered product that solves a problem nobody actually has the way you assumed they had it. The technical work is not wasted in the abstract. It is wasted in the specific. The next product you ship will involve different code because you will have learned what the audience actually does.
Why Your Instincts Are Particularly Untrustworthy Here
You are highly competent at building software. That competence creates a distortion field. Things that look easy or obvious to you are not easy or obvious to your customer. Workflows that you find painful are not always the workflows your customer finds painful.
If you are building for non-technical users, this gap is enormous. If you are building for other technical users, the gap is smaller but still meaningful. Your bias toward elegant abstractions does not match your customer's bias toward escape hatches and quick fixes.
Problem interviews are how you find out where your instinct is wrong. You will not figure it out by thinking harder. The data lives outside your head.
The Engineering-Brain Reframe
If it helps, think of problem interviews as input gathering for a system you are about to design. Before you commit to an architecture, you would spec the requirements. Interviews are spec gathering, just for the human-side requirements that no doc captures because no doc exists yet.
Skipping interviews is like writing the system without the spec. You can do it. The system might even compile. Whether it serves any actual purpose is a separate question, and you find out by running it - which, for a product, means launching to silence.
The Specific Failure Mode
The most common technical-founder failure mode is over-engineering for an imagined power user while the real audience is more casual. You add settings. You expose configuration. You support edge cases. The product becomes complex.
Then you launch. The casual audience finds the product overwhelming. The power user audience does not exist in the volume you assumed. The product flops not because the engineering was bad but because it was aimed at a user who was not there.
Interviews would have caught this. The interviewees would have shrugged at half the features you spent weeks on and lit up about the one simple workflow you under-built.
The Lazy Path Is Cheaper
Run ten interviews. Two weeks. Maybe three. Then build. The build will be narrower, more focused, and aimed at things real users said they care about. It will ship faster because the scope is smaller. It will land better because the aim is grounded.
The trade is genuinely good for technical founders. You gain calibration. You lose two weeks. The two weeks would have been spent over-engineering anyway.
Why This Compounds for Technical Founders
Technical founders who learn this skill early gain a compounding advantage. The combination of being able to build and being able to validate is unusually rare. Most builders cannot validate. Most validators cannot build. The founders who can do both ship products that work, repeatedly, and they look like they have some kind of superpower.
They do not. They just stopped letting their building reflex outrun their listening reflex. Problem interviews are the practice that builds the second reflex. Worth more than another framework, another stack, or another tool. Cheaper than any of them.
