He grew an email list in the niche first, pre-sold lifetime licenses before writing any code, and later pulled in Google traffic with programmatic SEO pages, reaching about 30K dollars a month.

Subscribr's 7 tactics

Subscribr · B2C · AI scriptwriting for YouTubers

Pre-sell 50 cheap lifetime licenses, raising the price every 10, with full refunds

Sold out in 2-3 days for $20K before any code was written

After mocking up the product, offered 50 lifetime licenses at an 'absurdly low' price. The first 10 were cheapest and the price rose for each following batch of 10 to create FOMO. An offer so good people say yes, even if the first 10 were not profitable. Money-back guarantee: buyers could ask for a refund at any time; product promised within 60 days, then 2 more weeks to try it and request a refund. Treated a sell-out as validation.

Email daily for 7 days teasing benefits, then give only the launch date

Part of a presale that sold out in 2-3 days

Seven days of daily emails teasing the product's benefits (features too, but mostly emotional benefits and how it changes their life). Near the last day, push the coming presale but give no details, only a date. On launch day, queue several emails so people know exactly when it goes live, send reminders when the presale is about to end, and be highly visible on all social channels throughout.

Set a presale goal of 3 months' costs, then work out buyers needed

Target of $20K and 50 buyers was hit

Decided validation meant ~$20K, enough to fund about 3 months of his life building. Divided by his target price point for this customer type to get 50 buyers, then used expected conversion rates to estimate how big the email list needed to be before launching the presale.

Start a new X account, follow the niche, trade free tools for emails

Built an email list of 1,000+ people in a niche he was new to

Opened a brand-new X account with zero followers and followed everyone in the YouTube creator space. Created small free resources of value using his software skills and distributed them via viral giveaways on X to collect emails. Also posted raw build-in-public stories of his thinking to build trust.

Email your list weekly and personally ask each subscriber about your app idea

Feedback told him he had something worth pre-selling

Emailed the list about once a week with new findings, and in the background reached out to each subscriber individually to discuss the app idea. Replies to the emails became idea feedback. Weekly contact kept engagement high enough for the later presale.

Run faceless YouTube channels yourself to find the painful step: scriptwriting

Found the problem behind a $30K/month tool

While posting YouTube videos about his next-company ideas, he started building faceless YouTube channels with a team. Scriptwriting was the bottleneck: good scriptwriters were hard to find and ChatGPT's scripts were not good enough. He bet his developer and founder experience could build a tool that worked.
