Lay the Groundwork with Problem Clarity

Before writing a single line of code, reduce ambiguity around the problem you are tackling. Map the job-to-be-done, capture frustrations, constraints, and desired outcomes, then align your promise narrowly. Clarity here shortens build cycles, improves interviews, and keeps every experiment laser focused on learning that matters.

Interview to Learn, Not to Sell

Use open questions about recent behavior, not hypotheticals. Ask for screenshots, calendars, and invoices to ground stories in facts. Summarize what you heard, confirm understanding, and avoid pitching. Curiosity builds trust and uncovers constraints that later become differentiators in your product.

Landing Pages, Waitlists, and Smoke Tests

Describe the outcome, show pricing, and add a strong call to action. Buy targeted traffic, track scroll depth and click maps, and email responders quickly. Compare conversion across audiences, headlines, and promises to see where resonance emerges before writing production code.

Deposits, Preorders, and Letters of Intent

Ask for deposits that are refundable but meaningful, or secure a signed letter of intent describing problem, scope, and price. These artifacts force specificity and internal alignment. Celebrate small commitments because they validate urgency and shape the earliest version worth building.

Prove Real Demand Before You Build

Replace assumptions with small commitments that cost prospects something real: time, reputation, or money. Conduct structured discovery, run smoke tests, collect deposits, and track conversion through each step. When people volunteer effort repeatedly, you have signal stronger than compliments or likes.

Design the Minimum Lovable Product

Build the smallest thing that reliably delivers the promised outcome, then make the edges feel human. Remove choices, reduce setup, and highlight progress. Delight appears when friction disappears and results arrive fast, turning early customers into advocates who eagerly invite their peers.

Prioritize With Evidence, Not Ego

Score ideas by impact on the core outcome and ease of implementation. Use RICE or ICE frameworks lightly, then verify with interviews and data. Defer everything else. Speed compounds when you only build what shrinks time-to-value and increases weekly active usage.

Onboarding That Leads to the Aha Moment

Guide new users through one meaningful action that demonstrates value immediately. Remove optional steps, provide defaults, and show a sample result. Celebrate completion with clear next steps. Shortening the path to that moment increases retention and fuels word of mouth.

Read the Signals of Product–Market Fit

Look for users who would be very disappointed if your product vanished, strong weekly engagement, organic referrals, and expanding account usage. Triangulate quantitative metrics with heartfelt testimonials and support tickets. True fit feels like being pulled forward, not pushing uphill constantly.

Cohort Retention and Usage Depth

Plot retention by signup month and watch curves flatten above a threshold that sustains the business. Measure depth with key actions per user, per week. If value compounds over time, expansion revenue appears, churn drops, and you feel that unmistakable pull.

Activation, Time-to-Value, and Habit Loops

Track how quickly a new account reaches the first meaningful success event, then repeat it consistently. Design cues, routines, and rewards that encourage regular use. When behavior becomes automatic, your product graduates from occasional helper to essential daily companion.

Win Your First 100 Customers

Channel early energy into activities that compound: conversations, content, and communities. Show proof with case studies, benchmarks, and demos that tell real stories. Focus on a narrow beachhead, deliver astonishing outcomes, and let referrals multiply while you refine pricing and packaging.

Scale Responsibly Without Breaking Trust

Growth should strengthen reliability, not erode it. Choose boring, well-supported technologies, automate repetitive tasks, and document decisions. Invest in support, success, and reliability early. Customers remember how you handle hiccups, transparency, and recovery far longer than they remember your version numbers.
