FOMO is a social proof marketing tool that displays recent customer purchase notifications on e-commerce websites. Ryan Kulp acquired the original 'Notify' Shopify app in 2016 with a few hundred customers and grew it to serve over 30,000 websites and billions of notifications annually. The company was recently sold to Relay Commerce after six years of growth, with over $1M in annual revenue, driven primarily by building 104+ native integrations, strategic partnerships, and a commitment to serving 'honest entrepreneurs.'

UserFlow is a no-code SaaS platform for building in-app onboarding guides and product tours, co-founded by Espen Fries Jensen and Sebastian. Started in 2018 (initially as Studio One, a video platform), it pivoted to interactive in-app guidance in 2019. With just two founders and a bootstrap approach (no VC funding), the company has grown to nearly $1M ARR by focusing on exceptional UX, product-led growth, and word-of-mouth marketing.
