Product-Led Growth: 70K Downloads in 30 Days

Baydin launched Boomerang for Gmail with a two-month prototype and got 70,000 downloads in 30 days while still in private beta. Users were so desperate for the product they hacked around invite codes and hosted Chrome extension files on their own servers. That is what product-led growth looks like when you nail product-market fit.

In this episode, Aye Moah reveals how a team of just eight people turned a simple Gmail plugin into a profitable mid-7-figure business on under $400K in total funding. She explains how product-led growth powered Boomerang's expansion through viral loops, a porous paywall, and voluntary subscriptions that revealed their ideal pricing.

Baydin discovered their freemium SaaS pricing by letting users pay whatever they wanted. People started paying in multiples of 12, thinking in monthly terms, which revealed the price ceiling the team needed. That insight shaped their transition from free to a structured model that drove product-led growth at scale.

🔑 Key Lessons

• 🛠️ Build your MVP in weeks, not months, to test product-led growth fast: Baydin built Boomerang's first version in two months and launched into private beta immediately. The scrappy approach let them validate demand before investing in infrastructure.
• 💰 Use voluntary subscriptions to discover pricing: Instead of guessing a price, Baydin let users pay whatever they wanted. Payment patterns in multiples of $12 revealed users were thinking monthly, which shaped the eventual tiered pricing structure.
• 🚀 Build viral loops at moments of delight for product-led growth: Baydin prompted users to share at the exact moments they were happiest with the product. This low-cost tactic created sustained organic growth without any marketing budget.
• 🔄 Design a porous paywall that turns free users into promoters: Instead of a hard cutoff, Boomerang let free users extend access by referring friends or sharing on social media. The paywall itself became a customer acquisition channel.
• 📉 Keep referral programs simple or users will not engage: Baydin built a gamified referral wheel with variable prizes including Kindle Fires, but users found it confusing. The engineering effort far exceeded the growth impact.
