After more than two decades working alongside early stage companies, I’ve seen what makes startups succeed and what causes them to stall or fail. Success in entrepreneurship often comes not just from what you do right, but from what you avoid doing wrong.
Here are six hard lessons I’ve learned about what not to do when building a startup:
- Don’t Build in a Vacuum
Too many founders develop products without validating them with real customers. Avoid falling in love with your idea before the market does. Customer feedback should shape your product early and often. - Don’t Ignore Cash Flow
Running out of money is one of the most common reasons startups fail. Don’t assume revenue will come quickly, plan your runway carefully and monitor cash flow religiously. - Don’t Chase Every Opportunity
Focus is key. Startups often dilute their efforts by chasing too many ideas or markets. Nail one niche before expanding. Be strategic and say no more often than yes. - Don’t Underestimate the Importance of Team Fit
Hiring someone just because they’re talented isn’t enough they need to fit the mission, values, and work ethic of your startup. One wrong hire can derail momentum. - Don’t Delay Marketing
Many founders wait too long to invest in marketing or believe "if we build it, they will come." Early traction requires early storytelling, community building, and brand awareness. - Don’t Avoid the Hard Conversations
Whether it’s with co-founders, investors, or early customers, hard conversations are inevitable. Delaying them only makes problems worse. Transparency and communication are leadership fundamentals.
The journey is never perfect but learning what not to do is often just as valuable as learning what works.
