The $1M Mistake You’re Making Before Writing a Single Line of Code
How to validate B2B SaaS opportunities before burning through your runway
Imagine this:
A development team churning out code.
A sales team frantically making calls.
Money leaking out like water from a rusty pipe.
And yet—no clear understanding of what customer problem they’re actually solving.
Sounds absurd? Welcome to the world of misguided B2B SaaS development.
How to Stop Burning Millions on the Wrong Opportunity
“We just had technology looking for a problem. A solution looking for a problem.”
That’s how one product executive summed up their company’s failure after millions in funding had swirled down the drain like a toddler’s rubber duck.
That isn’t an isolated incident. In my research interviewing dozens of B2B SaaS leaders, this pattern emerges again and again. I’ve seen the same train wreck play out in slow motion throughout my career in B2B software—probably just like you have.
Running an engineering team is expensive, especially in today’s funding climate. Yet too often, these resources aren’t moving the company toward Product-Market Fit—they’re being wasted on unvalidated assumptions about customer needs.
Let me share two examples from my interviews with B2B SaaS leaders:
One startup hired full engineering and sales teams while still trying to discover what customer problem they were solving. They ran out of money before finding Product-Market Fit. Their dream didn’t die from a lack of talent or effort, but from a fundamental error in sequencing.
Even established companies fall into this trap. One Enterprise SaaS vendor spent 18 months and millions of euros building a solution—only to realize no customer wanted to buy it.
The Lightbulb Moment That Saves Millions
While most companies burn cash in the dark, some product leaders take a different approach. They systematically explore a dark room until they find the light switch. Once they flip that switch, everything illuminates at once.
One founder described their process:
“When I founded my company, I started by talking to about 30 potential customers. I mapped out how they had approached this problem. I concluded that it would make sense to start building something.”
No premature programming. No hasty hiring. Just methodical investigation that paid off.
When they finally launched, customers responded immediately. Why? Because they had already done the hard work of understanding exactly which problems to solve, for which customers, and how.
The Four Fatal Flaws That Kill B2B SaaS Opportunities
Miss any one of these four critical factors, and your product is dead before it starts. These separate winning opportunities from expensive failures.
1. Customer Problem: Does it actually exist?
Many B2B SaaS companies skip problem discovery entirely. One company learned the hard way that their problem didn’t exist:
“The management decided to create something without analysis to back it up. We developed a product, tried it out, and concluded that no one would pay for it. A lot of time was wasted.”
2. Customer Prevalence: Is Your Problem Common Enough?
A handful of interested prospects isn’t enough. You need a sizable group of target customers with the same challenge.
One founder got this right:
“We went to talk to companies [and we learned that] this is a real problem, because the process is so laborious, and companies also have to leave money on the table.”
They discovered a problem common and significant enough to warrant a new solution.
3. Current Solutions: Are They Bad Enough?
Your product can’t just be better—it needs to be dramatically better than existing solutions. Otherwise, inertia wins, and customers stick with “good enough.”
One product leader discovered an opportunity where an entire market segment was poorly served:
“Many competing digital solutions were made from the perspective of the head office and company management. No-one offered anything at all for the [practical work on the ground]. We focus on that.”
4. Budget Reality: Will They Actually Pay?
Interest and enthusiasm don’t pay the bills. Customers must have such an acute need for a solution that they’re ready to throw money at it.
The best proof? One founder told me what happened when they showed their prototype to a customer whose problems they had discovered earlier:
“The customer said the solution was so good that we should set up a company, that they would pay the costs upfront, and they would act as our reference customer.”
That’s real validation.
Why “Move Fast and Break Things” Breaks B2B SaaS
Tech’s favourite advice is silently killing B2B SaaS companies:
🚫 “Just ship something!”
🚫 “Get customer feedback quickly!”
🚫 “Move fast and break things!”
This might work for consumer apps—but for B2B SaaS? It’s a death sentence.
Enterprise software isn’t a mobile app you can pivot overnight. It’s an oil tanker. Course corrections are expensive, and U-turns are nearly impossible.
Flip the Sequence: Discover First, Build Later
The real difference between successful B2B SaaS leaders and the ones who burn through their runway? It’s all in the sequence.
They invest in deep problem discovery before writing a single line of code.
They treat opportunity selection like a scientific expedition, not a random walk in the dark.
Think problem discovery takes too long? Consider this:
✅ Two skilled people can validate an opportunity and discover the customer problems of even a complex domain in a few weeks or months.
❌ A full engineering and sales team can waste millions chasing the wrong problem for a year—or more.
One B2B product executive in my research put it bluntly:
“Product discovery is critical. The most certain way to fail in discovery is to not do it.”
The time spent validating the right problem is a rounding error compared to the cost of building the wrong solution.
