Three main mistakes startup founders make.

usually coz they have trust issues

they try to save money and do it all by themselves

1. Choosing wrong co-founders 2. Building something nobody wants 3. Spend too much money too early

Totally agree with your top 3 mistakes! A few other common ones I've seen: 4) Chasing funding before nailing product-market fit 5) Hiring too fast without validating roles 6) Neglecting to build relationships with potential advisors/mentors early on. Avoiding these pitfalls can really boost a startup's odds of success imho.

1. developing a product without a user 2. designing a business plan without the customer (economic buyer) 3. following startup/entrepreneurship cargo cult.
