🚀 WhatsApp's secret to massive success? A tiny, scrappy team of under 30 engineers building native apps on 8 platforms — no code reviews, no sprints, no feature bloat. Founder Jan said "no" to 99% of feature requests to prioritize simplicity & reliability for every user, even grandmas in remote towns. Quality > quantity. A powerful lesson for AI-native startups today: focus on core impact, ruthless prioritization & lean teams. #startup #engineering #WhatsApp #AI #productivity #leadership
