How One Startup Used a Single Instagram DM to Land 500 Beta Users

In this episode of Marketing for Startups with Fexingo: Early-Stage Growth, Founder-Led Marketing, and Scrappy Tactics, Lucas and Luna dive into a single, replicable tactic that landed 500 beta users in under a week. They dissect how a fintech startup called Pennywise (fictional name but real strategy) used personalized Instagram DMs — not ads, not influencers — to recruit power users from a competitor's comment section. They break down the exact message template, the targeting logic (people who commented on a specific post from Mint), the follow-up cadence, and the surprising conversion rate. Listeners will learn why this worked in mid-2026, how to avoid coming off as spammy, and how to scale a one-to-one outreach channel without burning out. No budget required, just a phone and a spreadsheet. #InstagramDM #GrowthHack #UserAcquisition #ScrappyMarketing #FounderLed #BetaLaunch #Fintech #Pennywise #SocialMediaOutreach #DirectMessage #ColdDM #MarketingStrategy #StartupGrowth #EarlyStage #Fexingo #FexingoBusiness #BusinessPodcast #StartupMarketing Keep every episode free: buymeacoffee.com/fexingo
