AppAlchemy: 12 Questions Answered From the Starter Story Interview, With Timestamps
AppAlchemy is an AI tool that generates mobile app designs, and its founder grew it with Reddit alone. In the Starter Story interview, founder Diego reports around $17,000 a month, four months after starting, with fewer than 100 followers on X and no ad spend. His method is a repeatable Reddit routine: warm up the account, collect many relevant communities, write posts that teach before they sell, and post the same piece widely two to three times a week.
We transcribed the interview with transcribe.so and asked it the same questions we ask every episode. Each answer below is written in our own words and points to who said it and the exact second, so you can check it in the video. All figures are self-reported by the founder and we have not audited them. We are not affiliated with Starter Story, and we sell a transcription service.

What does AppAlchemy do and how does it make money?
It turns prompts into mobile app designs quickly; he describes it as an AI coding editor, but for designing mobile apps (Founder, 01:20). It is a paid SaaS with more than 1,000 paying customers (Founder, 04:13). The interview gives no plan names or prices.
What numbers does the founder share?
Around $17,000 a month, from a product he started four months earlier (Founder, 00:58). Reddit alone put it in front of over one million people with no marketing spend (Founder, 01:03). More than 1,000 paying customers, about 20,000 signups from Reddit, and about 20,000 visitors a month (Founder, 04:13). Margins are about 70% (Founder, 10:39). The host notes he had about 70 followers on X when he first reached out (Host, 00:04).
Where did the idea come from?
From his own bill. He paid a freelance designer hundreds of dollars for a mobile app design (Founder, 01:33), and every small change cost extra (Founder, 01:43). An AI tool could save people that time and money (Founder, 01:47). Having had the problem himself was his first sign of demand (Founder, 02:04). The interview says nothing else about his background.
How long did it take to build, and with what?
About two weeks for the simplest possible MVP, then straight to marketing on Reddit (Founder, 02:11). His speed tips: avoid the newest libraries, because AI assistants are best at the most widely used ones (Founder, 02:28), and lean on ready-made UI component libraries (Founder, 02:38). The stack is a mainstream JavaScript framework with a hosted backend for auth and database, built in an AI coding editor (Founder, 10:22).
Who is the customer?
People who want to build a mobile app and would otherwise pay a designer, like he did (Founder, 01:33). When he searches for communities, he starts from topics such as no-code (Founder, 06:33). The interview does not describe a narrower group.
How did the founder use Reddit to validate and market AppAlchemy without an audience?
He says his first $1,000 in MRR and more came purely from Reddit (Founder, 02:16). He calls it the most underrated channel: reach at no cost (Founder, 04:44) and precise targeting, because there is a community for almost every topic (Founder, 05:05). His five steps:
-
Become a real user first. Use Reddit daily to learn what works and to warm up the account, since posts from new accounts are filtered automatically (Founder, 05:36).
-
Build a long list of communities, broad and narrow. His trick is Reddit's ad tool: start a campaign, never pay, and use its community targeting to find related subreddits (Founder, 05:59).
-
Write a post that gives value first. Pushy posts built around the product fail (Founder, 06:33). Start with a catchy headline (Founder, 07:01), give something useful, then plug the product. His winner was a case study of a successful mobile app (Founder, 07:28).
"every successful post starts with a catchy, attention-grabbing headline" (Founder, 07:01)
Where links are banned, he mentions a complementary product next to his own, which lowers the odds of removal (Founder, 08:24).
-
Post it to many subreddits. Volume raises the chance of hitting the front page, and even ten posts at about 10,000 views each add up to about 100,000 (Founder, 09:23).
-
Repeat with new formats, two to three times a week at most, or risk a ban (Founder, 09:50).
What does a post that fails look like?
He shows one: the product is named in the headline, the body lists features and links a chat server, and engagement is poor because readers wanted something interesting first (Founder, 08:51).
Which single post moved the numbers most?
He shows his best-performing post, the mobile app case study, as the model for the structure (Founder, 07:01). He does not give its view count or the signups it brought.
What does it cost to run?
The AI backends are the biggest cost at about $2,500 a month (Founder, 10:46), with about $20 a month for his coding editor and about $40 a month for hosting, and overall margins of about 70% (Founder, 10:39). Marketing costs nothing (Founder, 01:03).
What lessons does the founder draw?
Solve a problem in a growing market, such as tools for AI-assisted coding, not one in decline, such as tools for newspapers (Founder, 11:13). Spend your early time on marketing, not features nobody asked for, and use a small team's speed (Founder, 11:40). He describes no failure of his own.
What is the founder's advice?
"Right now is the best time to build." (Founder, 12:02)
Get a simple MVP and start marketing it as soon as possible (Founder, 12:07).
What did the host take away?
That you do not need an audience: a good working product and a strong marketing routine were enough (Host, 12:14).
The interview does not cover pricing: no plans, prices or price changes are mentioned.
What to copy
- Use ad-targeting tools for research, not ads. The suggestions they make are a free map of every community your buyer is in.
- Write one strong post and distribute it, instead of writing many weak ones. The work is in the headline and the value; the reach comes from volume across communities.
- Teach first and mention the product last. It reads as a contribution to the community, which is also what keeps the post from being removed.
