Early-stage SaaS founders win by narrowing focus, starting marketing early, and building trust. Niche down to a specific ICP so your messaging speaks to real pain (e.g., third-shift hiring in manufacturing). Don’t wait for product readiness—begin 1–2 years ahead with thought leadership and top-of-funnel content so buyers know you before launch. Craft a unique perspective: map ICP challenges, use their language, and tie outcomes to problems. Use AI as an accelerant, not a shortcut—configure custom GPTs with your ICP, brand voice, and verify every claim. Invest 10–30% of seed in marketing, and leverage low-cost tactics: show up where your ICP gathers, give value, and win your first 25 customers personally. Balance sales and marketing; brand lifts average reps and shortens cycles. Iterate continuously based on feedback and market shifts. Pick one niche, publish one ICP-specific insight this week, and start a 90-day value-first marketing cadence.
