After working with dozens of startup founders, I've noticed the same patterns repeat. The same excitement. The same blind spots. The same lessons learned the hard way.
If you're building right now, here's what I'd want you to know upfront:
1. 𝐁𝐮𝐢𝐥𝐝 𝐟𝐨𝐫 1,000 𝐮𝐬𝐞𝐫𝐬, 𝐚𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭 𝐟𝐨𝐫 100,000
I still remember watching an app freeze on launch day. The founder had a flood of signups—exactly what he wanted. Then nothing worked. The database couldn't breathe.
Firestore rules. Cloud Functions. Caching strategies. These sound like "tech debt" until they're "why is my app crashing." They're not nice to have. They're survival tools.
2. 𝐘𝐨𝐮𝐫 𝐢𝐧𝐯𝐞𝐬𝐭𝐨𝐫𝐬 𝐰𝐨𝐧'𝐭 𝐮𝐬𝐞 𝐭𝐡𝐞 𝐚𝐩𝐩. 𝐘𝐨𝐮𝐫 𝐮𝐬𝐞𝐫𝐬 𝐰𝐢𝐥𝐥.
Demo day happens once. Tuesday at 2pm happens every week.
Founders pour energy into what investors will see. But the busy mom trying to reorder her kid's favorite snack? She doesn't care about your pitch deck. She cares that the button works and the checkout doesn't glitch.
That's where retention lives. That's what actually builds a business.
3. 𝐓𝐡𝐞 "𝐬𝐢𝐦𝐩𝐥𝐞 𝐚𝐩𝐩" 𝐝𝐨𝐞𝐬𝐧'𝐭 𝐞𝐱𝐢𝐬𝐭.
Someone asks: "Can we just add a quick cart feature?"
Quick cart touches:
• Authentication
• Inventory logic
• Payment processing
• Order state management
• Push notifications
• Tax calculations
Every "small" feature is a system. Respect the system, or the system will humble you.
4. 𝐇𝐢𝐫𝐞 𝐟𝐨𝐫 𝐩𝐫𝐨𝐛𝐥𝐞𝐦-𝐬𝐨𝐥𝐯𝐢𝐧𝐠, 𝐧𝐨𝐭 𝐣𝐮𝐬𝐭 𝐜𝐨𝐝𝐢𝐧𝐠.
I've worked with developers who write beautiful code that solves the wrong problem. And I've worked with developers who write simple code that asks "why" before "how."
The best ones challenge assumptions. They ask "who is this for?" and "what happens if?" They save you from building the wrong thing perfectly.
That's what I try to bring to every project.
5. 𝐘𝐨𝐮𝐫 𝐚𝐩𝐩 𝐢𝐬 𝐧𝐞𝐯𝐞𝐫 "𝐝𝐨𝐧𝐞."
Launch day feels like a finish line. It's not.
Real work starts when real users show up. Feedback comes. Priorities shift. You learn what actually matters.
Budget for iteration. Plan for change. Build like you'll need to rebuild.
Founders: What lesson did you learn the hard way? Drop it below—I genuinely want to hear.
Recruiters: Following these conversations is how you spot developers who think beyond syntax. Let's connect.
