Successfully launching a product requires strategic efforts to gain the first 100 users, which lay the groundwork for future growth. This involves leveraging existing networks and engaging in genuine community interactions, as well as creating content optimized for SEO to attract organic traffic. Platforms like Product Hunt and Lovable Launched are valuable for reaching early adopters, and offering incentives like lead magnets can help expand the user base. Effective use of social media and cold outreach, when personalized, can also be beneficial, while collaborating with niche influencers can enhance credibility. Testing and iterating on ideas, such as through A/B testing, helps refine strategies, and only considering paid acquisition as a last resort can balance cost-effectiveness with growth. Once the first milestone of 100 users is achieved, scaling up involves deepening user engagement, expanding reach, and continuously enhancing product value based on feedback.
