Interview with Jonathan Fishner, co-founder of ChartDB — built a niche app to $9K MRR

Developers are taught to hunt for moonshot ideas. Jonathan Fishner did something quieter and smarter: he picked one tiny, painful corner of the developer workflow, made that corner delightful, and let the audience adopt it on their own terms. The result is ChartDB — an open source, self-hosted database visualization tool

AI app growth

Interview with Timo Köhler, Builder of a $50K Per Month AI App

Interview with Timo Köhler, Builder of a $50K Per Month AI App Most solo builders do not need another $97 playbook explaining why they should “build in public” until their thumbs stop working. They need a repeatable way to find customers, know what those customers are worth, and scale without

Interview with Ryan Yao, the Designer Who Turned a Cat Pomodoro Timer Into an $18K-a-Month App

Most AI-powered launch system for creators conversations start with a pile of tools, a complicated workflow, and someone insisting that the right prompt will replace actual taste. Ryan Yao’s story is more useful than that. He and his girlfriend built Cat on Chair, a playful Pomodoro timer for cat

Interview with Nevo David, Founder of Postiz and Builder of an Agentic Social Media SaaS Most advice about building an AI-powered launch system for creators gets stuck in the same loop: add AI, post vaguely about AI, wait for the algorithm to hand over a bag of money. Very elegant.

solopreneur

Interview with Jack Friks, the $40K/Month Solopreneur Building Apps Around His Own Problems

Most solo builders do not need another productivity doctrine, color-coded second brain, or $97 “work four hours a week” PDF written by someone who apparently outsourced reality. They need a way to build useful things, listen to customers, and stay sane long enough for the compounding to happen. Jack Friks

AI apps

Interview with Tomer, the Builder Who Localized an AI Calorie App to $80K a Month

Original ideas are wildly overrated. Not because originality is bad, but because most solo builders use it as a very expensive procrastination device. They spend six months trying to invent a market category, then act surprised when nobody understands the landing page. Tomer took the less glamorous route. He found

iOS app building

Interview with Will Baker, the iOS App Builder Behind a $10K/Month Lazy Method

Most solo builders do not need another sermon about waking up at 5 a.m., posting twelve times a day, and turning every hobby into a personal brand. They need an AI-powered launch system for creators that can get a useful product live, test demand without building an influencer management

Cal AI

Interview with Blake Anderson and Zach Yadegari, the Young Founders Behind Cal AI

Building an app has become absurdly accessible. That is good news, right up until the App Store starts feeling like a digital flea market where 400 identical habit trackers are fighting over the same exhausted customer.

Customer Discovery

Interview with Gaurabh Mathure, Product Designer Who Turned 72 Apps and Zero Revenue Into $6,500

AI startups

Interview with Reza, Creator of an AI Manifestation App That Reached $30K a Month

Most first-time builders do not fail because they cannot code. They fail because they spend six months building a large, vague product for a market that may not care. Reza took the opposite route. He found a specific behavior already happening on TikTok, built the smallest product that could serve

AI rendering

Interview with Piotr, the Solo Developer Who Simplified an AI Rendering App to $10K a Month

Most builders do not fail because they lack ideas. They fail because their product makes the first useful outcome feel like filing taxes in a submarine.

SaaS

Interview with Gaurav, the Founder Who Built a $69K/Month SaaS by Actually Talking to Customers

Most startups do not die because the founder had a bad idea. They die because someone spent three months polishing an idea that customers quietly did not care about. It is a very expensive way to receive feedback, especially when the feedback is silence. Gaurav, founder of Fastlane, built an

Interview with Roman, Founder of CareerHound and Builder of a $25K a Month Job Board

Most solo builders are currently being told to build an AI agent, an AI wrapper, or some mysterious “AI-powered launch system for creators” that apparently prints money while everyone sleeps.
