Why Startups Fail: “The Mistakes We Made Boiled Down to One Thing”

Many startups fail by not validating their ideas early on with real-life customers. Entrepreneurs need to get out of the building and validate their ideas with actual customers. Only by searching for the real pain points and unmet needs of the customer, can you find a proper solution supported by the proper business model.



Remember, it doesn’t matter how passionate you are about your idea and how great you think your product will work, all that matters is what your customers think of your product.

For example, according to Business Insider, the startup Dever failed because they focused on ”on building the accelerator while minimizing our contact with users and customers.” The founders reasoned that they “knew how great it (the product) was and time spent talking to customers was time we could be hacking!” In a Lessons Learned blog post, the founders shared that they “should have focused more on customer development and finding a minimum viable product (MVP).”

Building a startup is not about building a business model of what you think works, but the process of searching for the actual business model itself.

How do we nail the business model? The key answer lies in rapidly testing your theories with customers in order to deliver the minimum viable product necessarily to satisfy your customers’ needs. Therefore, you need to get out of the building and constantly ask your customers not about improving your product ideas, but to identify their needs and pain points first. From there, you can then ask yourself whether your product idea can solve your customers’ needs and pain points.




If your product idea doesn’t fit with your customers’ needs and pain points, then you need to ask yourself “why?” and figure out how your product can meet market fit. You may need to pivot and change your whole product idea before you find the one that works. This step is the first crucial process of seeking the business model that works: finding product-market fit.

Once you figure out your product-market fit, you can move on to planning out your distribution model, key resources, key activities and other parts of the business that will help support your product delivery to your customers. Adhering to this process will save you months of work and give you a higher chance to succeed.

For more on the Customer Development process, key tools, and steps to build a successful startup, check out How to Build a Startup, by Steve Blank. In this course, you’ll learn the essential business skills it takes to bring your idea from conception to market.

New! Applied Cryptography Available with Certificates and Coaching

Whether you’re aware of it or not, every time you conduct a Google search, buy something on Amazon, or even log in to your Udacity account you are transmitting private information. 

The only thing preventing someone from intercepting and using that information is cryptography.

Bitcoin (the protocol) uses cryptography to securely transfer bitcoin (the currency) from one person to another
In Applied Cryptography, you’ll learn the science of secrets. Specifically, you’ll learn how to securely send messages and manage accounts securely on websites. You’ll understand the difference between symmetric and asymmetric cryptography and their common applications.

Today, we’re excited to announce Verified Certificates and Coaching support for Applied Cryptography. With the full course experience, you’ll have access to a personal Coach who will help you tailor your learning goals and offer their help if you get stuck on a problem. Plus, after solving some final problems, you’ll earn a certificate verifying your new cryptography skills.

Learn Differential Equations in Action

I remember starting engineering school and dreading the differential equations course I’d eventually have to take. Upperclassmen loved to taunt us with horror stories about professors talking a million miles a minute in math jargon and coursework so abstract and complicated that problems felt meaningless.

This is not that course.

Differential Equations in Action will teach you to create solutions to systems of differential equations using numerical approximation methods, which we’ll code in Python. 

The methods you’ll learn in this class are the same ones that physicists, engineers, biologists, economists, social scientists, and professionals in many other fields rely on every day in their work.

We’re very excited to now begin offering Coaching support and Verified Certificates for Differential Equations in Action. With the paid course, your personal Coach will be available to help you set learning goals and work through any problems you may be stuck on. Plus, after passing an assessment completing the course, you’ll earn a snazzy Verified Certificate to show off your new knowledge.

See you in class!
