Why Problem Interviews Matter More for B2B SaaS Than Founders Think

B2B SaaS founders often skip problem interviews because their network is the audience. They have worked at the kind of company they are now building for. They know the workflow. They have lived the pain. Why ask?

Because the network is biased and the workflow is wider than your slice of it. The interview round is what catches both.

The Specific B2B Trap

You worked at one company. You saw one variant of the workflow. You assume the variant generalizes. It usually does not. Other companies have different team sizes, different existing tooling, different compliance constraints, different decision-making structures. The pain point you remember is real. The shape of it is specific to where you saw it.

The Buyer-User Gap

B2B SaaS specifically: the user often is not the buyer. The user feels the pain. The buyer signs the contract. Founders who only interview users build products that users love and buyers do not approve. Founders who only interview buyers build products that buyers like in theory and users never adopt.

You need to interview both. The interview round forces this. Your network usually skews toward one or the other.

The Procurement Tax

B2B SaaS unique: every product has to survive procurement. Security review. Data residency. Integration requirements. Existing-vendor displacement politics. Founders who skip interviews do not surface these constraints until late, often after building a product that cannot pass procurement at the customers who would otherwise want it.

The interview round catches procurement constraints early when they are still cheap to design around.

What You Are Listening For

Specific tools they currently pay for. Specific workflows that span multiple tools. The handoff between user and buyer. The procurement constraints. The internal champion who would push for the purchase. The objection the CFO would raise. None of these surface in the "I lived this workflow" gut feel. They surface in conversation.

Why B2B Interviews Are Easier Than They Look

B2B operators love being asked about their work. Most rarely get the chance. A polite cold message asking for thirty minutes lands surprisingly often, especially if you are clearly not selling. Founders who try this are usually startled by the response rate.

The Bottom Line

Your network is a sample of one. The workflow is wider. The buyer is often not the user. Procurement is real. Problem interviews map all four. Skipping them because "you know the space" is the most common B2B SaaS validation mistake. Run the round.
