I quit my job 3 weeks ago. Today I’m launching my startup

Hello my friend. I did it. I fckng did it.

Three weeks ago, I quit my 9-to-5. Today, I finished my startup and I’m launching it: Polary.

Welcome to Polary. An AI cofounder that validates ideas, researches markets, builds launch plans in minutes instead of weeks, and guides execution step by step so you don’t waste time or money.

It’s still early, and I know there will be rough edges. I’m a bit nervous about this launch, but I hope you’ll welcome Polary warmly and help me shape it into something better every day.

On Monday, I rebuilt everything almost from scratch. By Friday, I had a full MVP — backend, frontend, AI agents, database, Stripe, Sentry, Google Analytics, Vercel, Supabase, domain, everything wired up and working. And not just wired up, but delivering: you type your idea, and under two minutes you get a validated business plan, a market analysis, financial projections, product roadmap, go-to-market strategy, and a step-by-step action plan. Then you can chat with your AI co-founder, who knows your entire context and guides you step by step.

I built the whole thing solo. Full backend, full frontend, full database, all integrations, all designs. In total, it’s been three weeks. Three insane, sleepless, failing-and-fixing weeks.

On August 4th, I left my 9-to-5. I was in Mykonos, celebrating the birthday of a friend who once saved my life. Almost everyone else was relaxing — I was building. I hadn’t taken a vacation in a year, but I couldn’t stop. I was failing, retrying, learning. I tested every LLM model inside Cursor, spent $500 on tokens, and when I refused to spend more, I figured out how to hack automation mode with better prompts and approaches. I didn’t know how to build AI agents. I didn’t know LangChain or LangGraph. I had never set up Stripe webhooks, Sentry, or built a full-stack app with design, hosting, analytics, and payments. And now I have.

Monday was the turning point. I wanted to fix a last bug before bed. Instead of going to sleep, I rebuilt my backend completely. Within one hour, I had a prototype working end-to-end. By 6 a.m. Tuesday, I had the core of the product. The rest of the week I slept at 3, 4, 5, sometimes 6 a.m. Every day, building.

I didn’t do it alone, though. Friends tested it. Some tested for days, some gave 20–30 minutes of sharp feedback. Others shared design ideas, output ideas, logic ideas. I couldn’t implement everything, but I logged it all. My backlog of improvements is inside the very app I built. I’m running my startup from inside my startup. I validated my own idea with my own tool. My AI advisor is advising me on how to launch itself.

That’s insane.

This is just the beginning. I’ve only built 3% of what I envision. I’m not going to build Cursor for entrepreneurs — I’m already building Cursor for entrepreneurs. An AI co-founder that validates your idea, researches your market, builds your launch plan in minutes instead of weeks, and guides execution step by step so you don’t waste time or money on guesswork.

And I’m building it for you. This isn’t marketing fluff. I mean it literally. It all started four months ago in a café. I posted on Reddit about my AI coding experiments, it blew up, and I built a free community. Then came the newsletter (now 3,450 subscribers, 40% open rates). Then paid guides on PRDs, product building, and more. Then a private curated community of 14 amazing people — small but powerful. We share, we test, we help each other. They’ve been with me every step. Screenshots, Looms, test links — I built in public, for them, with them.

Four months ago this was an idea. Today, it’s live.

I left my secure job at 24 because I believe there’s more for us as founders, makers, creators. Seven years ago I left my hometown, four years ago I left my home country, alone, because I knew I had to chase something bigger. Today, I live in a city I love. I’m not bragging. I’m saying: I took the bet, and I want to show you what happens when you take the bet too.

This is just the start. Maybe nobody will use it — maybe only one person will. That’s fine. I know now I can build from 0 to 100. I know I can learn anything. And if I can, you can too.

So here it is: my launch.

Under two minutes: your business idea validated, your market researched, your financials projected, your product roadmap built, your go-to-market outlined, and your next 20–30 steps ready. Then an AI advisor with your full context to guide you every step of the way.

This is for you ♥️

stay caffeinated.
lead the machine.
launch anyway.
