How Sunflower grows

A/B tested a priming screen right before the paywall with the mascot bee: 'We want you to try Sunflower for free. We'll remind you before your trial ends,' then shows the paywall. Addresses trial anxiety. Tested a couple of versions of the screen.

Before Sunflower had any revenue or monetization, hunted down the #1 sobriety influencer (Eric, 'Mr. Impulsive', 50-100M views/month, biggest on Facebook Reels then TikTok) and made him 'VP of Sobriety' with salary and equity instead of paying per post. Pitched it as a mission and a go-to-market role, not a post buy. He links the app in all his content, sits in the company Slack where the team shares user feedback ('this app saved my life'), knows the roadmap, and iterates on how he drives link clicks. Supplemented by a few smaller influencers and paid ads. Guest says the same was done at Reddit and Replicate; for bootstrappers suggests pitching a big creator a 50/50 partnership where you build an app for their audience.

Moved from a monthly-only paywall to adding an annual plan, then made the annual plan (paid upfront, no trial) the default selection, since paying annually right away is the best action for a consumer app. Also offers weekly, monthly and annual so users self-select.

Copied Tolan's paywall pattern: pay-first default with a toggle that lets users switch to a free trial.

Started as a ChatGPT wrapper, then prompt optimization, then an agent ('Sam') with app-wide context and memory: proactively follows up (e.g. on payday), replies to posts in the community, runs prompted sessions. Risky conversations escalate to a clinical team under a VP of Therapy; biometrics and data erasure protect users from abusive partners. Next: integration with a teletherapy clinic (relapse scores to therapists, homework follow-ups).

First deck led with the founder's track record (Rupa 5 to 75M, 4,000% UA growth), ~23K MAU, 762 reviews and a 1M downloads/month dream; it largely failed. Post-YC deck: a big future market, proof of product-market fit and outcomes (users staying sober), positioning within AI, a revenue chart going up (not users), and a letter of intent for a pilot to show a bigger market.

After 3-4 years of failing to fund the idea (even after growing Rupa), put in $100K of his own money and pitched people who had profited from Rupa's exit to invest.

Non-technical founder went through a coding boot camp (2020-2021) and built v1 himself because nobody would build it: a sobriety timer, sunflower graphics bought on Fiverr, and a simple CRUD journal. Launched on Product Hunt, then improved step by step.

Launched as a free product inspired by Duolingo's years of free growth, aiming to collect users and monetize later. Investors wanted revenue, and AI token costs scaled to hundreds of thousands of dollars, so introduced a first paywall with a single monthly subscription.

Because people struggling with addiction are very price-sensitive and often short on money, tested lowering prices rather than raising them.

The sobriety timer (how long you've been sober) is the core job to be done; the team focuses on making it as motivating as possible and bundles AI sponsor, tools, community and content around it. Guest says the AI companion alone would have horrible engagement, retention and payment.
