Foundations Course – Lecture 14 – Time and Money

By Yonatan Stern| 1.02 Hours| English| Part of the Foundations Course
In this lecture Yonatan explains why 90% of well-funded, talented teams fail. This lecture explores the root causes of startup failures, emphasizing the critical interplay between time and money.
  • The Real Reason Startups Fail: Despite what founders claim, 9 out of 10 startups fail simply because they run out of money and time. Pressured by the Venture Capital model to grow rapidly, founders hire massive teams before they know how to sell, which burns through their cash.
  • Play the “Infinite Game”:
  • Branding Before Building: Don’t fall for the “if you build it, they will come” myth. You should start branding and creating market awareness before you spend expensive resources developing the actual product.
  • Target a “Beachhead” Market: Chasing a massive, billion-person market right away is a mistake. Instead, focus all your efforts on a very small, well-defined “beachhead” market segment so you can penetrate it easily and reach profitability.
  • Focus on the “Job to be Done”: Customers don’t actually want to buy your product; they want to buy the end result (e.g., they don’t want to buy shoe polish, they just want their shoes polished). Understanding this changes how you price and market your solution.
  • Keep Your Team Tiny: Relying on Price’s Law (the square root of your employees do 50% of the work) and Parkinson’s Law (work expands to fill the time allotted), the speaker emphasizes that adding more people usually decreases efficiency and adds unnecessary overhead.
  • Build “Lock-in” for Renewals: To ensure customers renew their annual contracts, you must design your product so they accumulate history or data within it. Once a customer’s valuable history is trapped in your system, the chance they will cancel drops to near zero.

The VCs themselves say that 1 out of 10 succeeds. And if 1 out of 10 succeeds, they do so well that they cover the expense of all the other nine that failed and even make more money. So from the VC perspective, they are a great success. The question is what about the founders, what about the companies? If you look at the same sentence spelled slightly differently, not one out of ten succeeds, but nine out of ten fail. That starts to be much more interesting. Nine out of ten companies fail. The question of course is why do they fail? This CB Insights did survey for 101 companies and they got these answers. Don’t worry about reading them, but if you add up all the percentages you will realize that we get to about 300%.

If you get to about 300%, I would assume that many people filled up three answers at least or something like that. There are many reasons. And when there are many reasons, people give you a lot of answers, then basically they don’t have the real answer. They blame this and they blame that and were not ready and the market was full and all of that stuff. But so many answers mean there is no answer why they fail. Let’s look at it from the VC firms. They see hundreds of companies every year. When we talk to them it’s anywhere between 2 to 300 to 1000 companies that they talk to or see every year. At the end, they invest in somewhere between two to four companies every year.
