How Startups Grow with word of mouth

Tony is a Vietnamese indie hacker who quit his corporate job in August 2021 with only 300 MRR in revenue from Black Magic to pursue building multiple products. Within one year, he grew to nearly $20,000 MRR across three main products: Black Magic ($10k/month, a Twitter growth tool), Snapper ($4.2k/month, a screenshot tool), and Dev Utils (~$4k/month, a developer toolbox). His success came from building an audience on Twitter, creating products that solved his own problems, and leveraging viral loops that kept compounding.
