Software didn't make businesses more efficient — it just moved the filing cabinet onto a hard drive. From Sabre Systems to PeopleSoft to QuickBooks, humans still had to do all the work. Now AI can finally edit the filing cabinet, not just store its contents.
Where this was said

There's an unusual origin to Lassie's technical edge: its founders were, for a significant period, not software engineers but billing clerks. Steijn Pelle — former Robinhood growth lead — and Frédéric Renken — former Superhuman product manager — sat at the reception desks of dental and gastroenterology offices and did the work. They opened envelopes, deposited checks, reconciled ledgers, and navigated insurance portals by hand. The pitch to get in the door was, as Pelle admits, deeply weird: 'Hello, I work on Robinhood's referral program, can I do your billing?' But the fact that every single practice said yes was the founding data point. The trust these doctors extended — giving Pelle and Renken access to HIPAA-sensitive financial records, the lifeblood of their business — was itself evidence of the severity of the problem. Frédéric Renken would later attribute the product's 98% automation rate directly to this period: you cannot build a product that does a job you've never actually done.
With AI coding tools like Cursor, Bhanu replicates an existing free tool for a new keyword in under 5 minutes. What used to be a multi-day build is now a lunch-break task.
Ahrefs, SiteGPT, Cal.com, PostHog, Datafast, Sibyl AI, Bento, Feather, Featurepace, Mintlify, Cloud Code, ChartMogul — Bhanu runs his entire business solo with these 12 tools.
PropGPT runs on React Native with TypeScript and Python for ML, Neon for the database, RevenueCat and Superwall for monetization. LLM costs are $20/month, data APIs $100/month, and after $10K in monthly marketing spend, margins sit at roughly 50%.
Game apps keep users engaged long enough for ads to pay off. Tool apps don't — so if you're building a utility, ads are almost always the wrong call and subscriptions are your only real lever.
Inside SEO Bot, a single button labelled 'Boost My Domain Rating' routes users directly to Listing Bot. That one interaction converts a user of one tool into a user of two — without any marketing cost.
Directory listings are a powerful but underrated growth channel — but only if your product is genuinely interesting enough to earn the click. AI products have a natural advantage here because they're easy to package in a compelling, clickable way.
The fastest path to Twitter growth isn't volume — it's forming sharp opinions about how the platform works and sharing them immediately. People cluster around those who understand the rules and say so out loud.
Sam had no coding knowledge, so he used ChatGPT voice mode to generate his entire codebase and copy-pasted it into Notepad. A friend later introduced him to Cursor, and he never looked back.
Copy days of Discord chat history, paste it into ChatGPT, and ask it to list recurring pain points. The ones that come up most often are your best product bets.
