How Do You Validate That the Problem Is Real?
Identify a Real Problem
- Talk to at least 30 potential customers before building anything. Not friends, not family—real prospective buyers who match your target profile.
- Understand their pain points deeply. Ask about their current workflow, how they solve the problem today, and what a solution is worth to them. Listen for emotional language—frustration, anger, resignation—which signals genuine pain.
- Validate that the problem is significant enough to pay for a solution. A useful litmus test: if the prospect wouldn't pay at least $500 per year to solve this problem, you probably don't have a viable B2B opportunity.
Market Research
- Analyze the market size and opportunity. I recommend a bottoms-up TAM calculation: how many companies match your ICP, multiplied by a realistic annual contract value. Top-down TAM numbers from analyst reports are nearly always misleading.
- Understand the competitive landscape. In my experience, having competitors is actually a positive signal—it means someone else has validated that the problem exists. Your job is to find a wedge where existing solutions fall short.
- Identify your unique approach. What insight do you have that incumbents lack? Often this comes from domain expertise—you've lived the problem yourself and understand a nuance that outsiders miss.
Key Questions
- Is this a real problem people have?
- Are people actively looking for solutions—are they searching for it, discussing it in forums, or cobbling together workarounds?
- Will they pay for a solution, and at what price point?
How Should You Build Your First Product?
Build a Minimum Viable Product (MVP)
- Focus on core functionality that solves the problem. Identify the single job-to-be-done that matters most and build only for that. Everything else is a distraction at this stage.
- Avoid feature creep. Every feature you add increases your surface area for bugs, extends your timeline, and dilutes the signal from customer feedback. I tell founders: if it's not directly related to the core problem, put it on a "later" list and don't look at it until you have 20 paying customers.
- Get to market quickly. A good target for B2B SaaS is to have a usable MVP in 6 to 8 weeks. If you're taking longer, you're probably building too much.
Customer Feedback Loops
- Engage with early customers continuously. I recommend weekly check-ins during the MVP phase—not just support tickets, but genuine conversations about what's working and what's not.
- Iterate based on feedback. But be disciplined about it. One customer's request is an anecdote; five customers independently asking for the same thing is a pattern.
- Measure what matters. At the MVP stage, the metric that matters most is engagement: are people actually using the product after signing up? If usage drops off after the first week, you have a value delivery problem.
Key Principles
- Start simple, add complexity only when needed
- Build for your specific customers, not everyone. The temptation to build a "platform" is strong—resist it until after PMF.
- Focus on solving the problem, not building features
How Do You Know the Market Wants What You've Built?
Early Customers
- Find your first 10 to 20 customers. These are not beta testers—they are paying customers. The act of paying, even a small amount, is a fundamentally different signal than "I would use this if it were free." I've seen startups with thousands of free users struggle to convert a single one to paid. Charge from day one.
- Understand why they're buying. Is it because of the core value proposition, or because of a secondary feature? One of our portfolio companies discovered their "killer feature" was actually the CSV export—customers cared more about getting data out than the dashboard the team had spent months perfecting.
- Learn what's working and what isn't. Pay close attention to which customers succeed and which churn. The pattern will tell you who your real ICP is, which is often different from who you assumed it would be.
Metrics That Matter
- Customer acquisition cost (CAC) — at this stage, track it even if it's mostly founder-led sales. You need a baseline.
- Customer lifetime value (LTV) — even with limited data, project it based on current churn rates and contract values.
- Net Promoter Score (NPS) — anything above 40 at this stage is a strong signal. Below 20, and you have serious product-value gaps.
- Retention rates — monthly cohort retention above 85% for B2B SaaS is the bar I use as a minimum threshold for PMF.
Signs of Product-Market Fit
- Customers are actively seeking you out—inbound starts outpacing outbound
- Word-of-mouth growth. When customers start referring others without being asked, something real is happening.
- High retention and engagement. Users come back repeatedly and usage deepens over time, not just at onboarding.
- Customers become advocates. They'll give you testimonials, join case studies, and defend you in buying committees without being prompted.
What Does Scaling to Fit Look Like?
Optimize Your Model
- Refine your value proposition based on what your best customers actually care about, not what you assumed they would care about
- Improve your product based on learnings from your first 20 customers. At this stage, you should have clear patterns on what drives retention and expansion.
- Optimize your go-to-market approach. If founder-led sales worked, document the playbook: the emails, the demo script, the objection handling. You'll need this to hire your first sales rep.
Build Systems
- Establish repeatable processes. If you can't describe your sales process in a one-page document, it's not yet repeatable.
- Build scalable infrastructure. This doesn't mean re-architecting everything—it means addressing the specific bottlenecks that will break at 2x to 3x your current scale.
- Create systems for growth, including onboarding playbooks, support documentation, and customer success workflows
Key Focus Areas
- Product improvements based on customer feedback
- Sales and marketing optimization
- Operational efficiency
- Team building — your first five hires after PMF are among the most consequential decisions you'll make
What Separates the Winners from Everyone Else?
1. Customer Obsession
2. Speed of Iteration
3. Focus
4. Metrics-Driven
What Are the Most Common Mistakes?
- Building Too Much: Over-engineering the solution before validating the problem. I've seen teams spend 18 months in stealth mode building a product that the market didn't need. The cost isn't just money—it's the opportunity cost of 18 months of learning you didn't do.
- Ignoring Feedback: Not listening to customers or dismissing negative feedback. Founders who explain away churn ("they weren't our target customer") instead of investigating it are setting themselves up for failure.
- Premature Scaling: Trying to scale before achieving product-market fit. Pouring money into sales and marketing before you have a product that retains customers is like pouring water into a leaky bucket. Fix retention first, then scale.
- Feature Creep: Adding features instead of improving core functionality. When a customer churns, the answer is almost never "we needed more features." It's usually that the core promise wasn't delivered well enough.
How Does the Lean Startup Approach Apply?
Build-Measure-Learn
- Build a minimum version. The key insight is that the "build" step should be the smallest investment that generates useful learning. Sometimes that's a landing page. Sometimes it's a concierge MVP where you deliver the service manually.
- Measure customer response with concrete metrics, not vanity metrics. Signups are vanity. Activation and retention are substance.
- Learn and iterate. After each cycle, ask: what did we learn, and does it change our hypothesis? If yes, update the plan. If not, keep going.
Pivot or Persevere
- Know when to pivot based on learnings. A pivot is not a failure—it's an informed course correction. Some of the most successful companies in our portfolio pivoted at least once before finding PMF.
- Don't pivot too early or too late. Too early means you gave up before gathering enough evidence. Too late means you burned runway chasing a dead end. My rule of thumb: give each hypothesis at least 8 to 12 weeks of genuine effort before considering a pivot.
- Make data-driven decisions about whether to change direction
What Tools and Frameworks Should You Use?
Customer Development
- Customer interviews — I recommend the "Mom Test" framework by Rob Fitzpatrick, which teaches you to ask questions that even your mom can't lie to you about
- Problem-solution fit canvas
- Value proposition design
Lean Startup
- MVP development
- Build-measure-learn cycles
- Pivot framework
Metrics
- North Star metric — pick one metric that best captures the value you deliver to customers and orient the entire team around it
- Leading and lagging indicators
- Cohort analysis — this is the single most important analytical tool in the pre-PMF phase because it reveals whether your product is actually getting better over time
