Virality and word-of-mouth tactics

Comparing Israel (viral, #1) with other markets showed one key difference: network density. They tracked the percentage of new users who got 5 friends on day 1 (~60% in Israel vs ~20% elsewhere), which went with D90 retention of 25-30% vs about half that. The conclusion was to raise density 'whatever it takes' through growth features where users invite friends by using the product, not content marketing (which brings random people without friends). They shipped the common invite and sharing mechanics plus unusual ones (Group Picture, one-minute roll call). Content still seeds the first users, but product-led invites scale it.

Launched a free-for-life plan and put it front and center everywhere, including ads ('free-for-life ads'), to attract very small price-sensitive maid services who may pay later. Everyone goes through the same signup requiring credit card details, even for the free plan, and gets a 14-day trial with all paid features before choosing.

After the (blurred) scan result, the paywall offers two buttons: 'View results' (-> paywall) or 'Invite 3 friends'. Inviting leads to a share-your-invite-code screen; results unlock free once 3 friends download, finish onboarding and redeem the code. Friends get no benefit beyond helping. Target users are 13-25 and don't want to pay, so they post codes in TikTok comment sections. Branch was used for attribution/referral links. Repeated on Sprout and the newest app.

Trained an in-house model that predicts a speaker's origin from ~10 seconds of speech and launched it as a separate web app (accentoracle.com): no download, no gate, no trial; record your voice and get results instantly, then get invited into the BoldVoice app. Shared it in the monthly investor update; a Korean angel investor posted it on Threads. After it spread, invested in accuracy and stability.

Launched the first digital program in January (New Year's) as a 30-day group challenge: day-1 and day-30 photos, prize (~$100) for the winner, daily coaching in a Facebook group. Repeated monthly (Feb, March...). Used participants' before/after photos as organic marketing to a ~5K-follower Instagram. No paid media for years; growth spread by word of mouth.

Open X, LinkedIn and Instagram/Facebook friend lists in three tabs, go through every contact and circle anyone who fits the ideal customer (here: anyone with an event coming up), then ask them to try it. Apply The Mom Test: friends and family are encouraging, so be honest about whether you're validating or just looking for encouragement.

Spot a meme early (DaBaby's head as a car, seen the day it came out), pull an all-nighter building a simple game around it in a no-code builder (Buildbox), and put it on the App Store; then hire Unity developers once money comes in. A game makes a 2D meme interactive (you can be DaBaby), which is funnier and gets shared. Rafael ran this playbook on many meme games (e.g. a vegan teacher game).

Create accounts branded as an official sub-page, intern or co-founder of the app, with the App Store (or brand page) as the link or mention in bio. Warm each up so its Reels feed shows trending content in the target niche, using AI prompts that analyze videos and engage with fitting ones and skip the rest. AI also scans comment sections: skip videos full of irrelevant comments, reply where people are actively engaged, and reply only to people who ask questions or give opinions (not 'thanks for the video'). Comments must be context-dependent, never copy-pasted promotion; run several sub-campaigns with different angles. Funnel: comment -> reply or profile visit -> link in bio -> App Store. Most results come from a small share of comments that get exposure.

Jack launched Lovely with a simple tweet: what the app does (love notes on your partner's home screen widget), shown in context, plus the goal of taking it from $0 to $5K/month in 10 weeks. He quote-tweeted it about six times with updates and context; each one got more views because it was a story (can he hit the goal?) and a cool product. When Russian news covered the app, he tweeted about that too. When a user posted the widget used as a grocery list (16M views), he quote-tweeted it with 'I made this app, someone's now using it as a grocery list'.

A tree grows on screen as the user answers questions (plus a jungle river, XP, levels, unlockable trees and a chosen character). Because students study close together on campuses and in libraries, passers-by see the tree and ask what it is.

Noticed 'crashing out' was a viral emotion (Chloe's rant video, Justin Bieber's Nobu Malibu outburst turned into an album billboard). Added a big red 'crash out now' button that launches a breathing exercise, then posted a funny two-slide TikTok slideshow showing it.

For the Series Hamptons campaign (a TV-show-style series with 12 intern spots), Series put up a LinkedIn post and LinkedIn job, got ~2,500 applications, and Eunice personally texted many applicants to invite them into a 'race to the Hamptons' rather than just picking 12. About 150 joined. The race had challenges; one of the last was to invite as many people as possible.
