Supergrow

Devon had virtually no audience when he started — only ~600 Twitter followers and ~500 LinkedIn followers, and just 2-3 customers before launch. His first meaningful user acquisition came entirely through a Lifetime Deal (LTD) launch on the platform Rocketub. Rocketub reached out to Devon after noticing his journey on LinkedIn and offered to run the launch. Rocketub handled all marketing: emailing their list of hundreds of thousands of LTD buyers, running Instagram and Facebook ads, and creating all marketing assets (screenshots, videos). Devon's only role was building the product and handling customer support. The LTD launched at three tiers ($79, $199, $299) and was capped at 300 users over 3 days, generating $65,000 in gross revenue (~$40,000 net after Rocketub's 40% cut) and onboarding 250+ LTD customers. Of those 250+ LTD customers, roughly 20-25 became highly engaged power users who gave brutal, detailed product feedback via Intercom. These customers also became product evangelists — posting about Supergrow on LinkedIn, Twitter, and WhatsApp groups, which seeded word-of-mouth well before any organic growth efforts began.

Rocketub (an LTD platform) proactively reached out to Devon after spotting his LinkedIn journey posts — Devon didn't have to find or pitch the platform himself. This inbound partnership gave him access to a massive pre-built buyer list he never could have assembled independently as a solo indie hacker with no audience.

Devon does not explicitly call out failed channels. He implies that launching with cheap annual plans or free plans would not have generated sufficient revenue or validated feedback — free users tended to ghost rather than give useful feedback, and cheap annual plans wouldn't create the same urgency or cash infusion as LTDs.
