Before building, founders in complex industries must deeply understand the operational rigor and nuances of their target vertical. This 'operator market fit' ensures the solution addresses real-world workflows, as a one-size-fits-all approach is doomed to fail.

Standard "discovery interviews" are often a form of "playing founder." It's arrogant to believe a few 30-minute conversations can yield the deep insights needed to build a game-changing product. True understanding comes from immersing yourself in the customer's work, not just casually interviewing them.

As companies grow, communication becomes fragmented across more people, increasing the risk of "translation errors." Regular, firsthand customer experience for all roles—not just founders—is essential to prevent internal models from diverging from customer reality.

Police are paradoxically resistant to change while also being dissatisfied with current conditions. This creates a challenging but navigable path for technology adoption. Founders must frame innovations as inevitable, beneficial evolutions rather than disruptive shifts to succeed in this market.

Alex Karp advises tech founders new to the defense sector to first build empathy and understanding by visiting a military base and talking with enlisted personnel and their families. He warns that approaching generals without this foundational context is a "huge mistake" that is likely to backfire.

The strongest companies are built by founders who have personally and painfully experienced the problem they're solving. This visceral understanding is non-negotiable. Without it, founders can't know what to build or how to achieve third-party validation, wasting immense time and resources.

Don't jump straight to building an MVP. The founders of unicorn Ada spent a full year working as customer support agents for other companies. This deep, immersive research allowed them to gain unique insights that competitors, who only had a surface-level idea, could never discover.

The only reliable way to understand a customer is to "forward deploy"—work alongside them in their actual environment. This direct experience of their job closes the context gap that interviews can't bridge, revealing unspoken needs and frustrations.

To truly understand B2B customer pain points, data and interviews are insufficient. Product teams must immerse themselves in the customer's environment, such as by working for an advertiser for a week or shadowing an accountant for a day, to gain firsthand workflow experience and develop deep empathy.
