Nicolaj was instrumental in getting Recon Instruments off the ground. As one of its first shareholders, he led the first angel round and subsequently helped raise millions of dollars from angel investors around the world, using his network and expertise to identify people that would invest in what seemed at the time to be a crazy idea. His personal drive and ability to simplify and drive clarity was hugely beneficial in navigating the sometimes complex process of early stage fund raising. I strongly urge entrepreneurs to follow his pragmatic advice in this book. It will get you results.

Getting a startup actually started, funded, and then operational is not for the faint-of-heart. It’s a complex and generally daunting process. Nicolaj’s “The Startup Funding Book” is your go-to how-to manual for navigating your path in building a startup you can be proud of. As an entrepreneur myself, I can say the book needs to be on your list of required reading!

Nicolaj Nielsen shows you how to analyse what funding your venture needs and assesses the pros and cons of every major source. He then helps you reverse-engineer the way investors will think about financing your business and teaches you how to align your pitch with their mindsets. The section on how to find and work with a co-founder is worth the price of the book alone. Read this book before you start your business — its practical, intelligent advice could save you many months and missteps.

Philip Anderson, INSEAD Professor of Entrepreneurship

When I read business books, I normally set out to highlight everything I find important in it with a yellow marker. I drop some books half way because I have marked almost nothing. I read others to the end because I frequently find important passages to mark up. And then occasionally I read books where I have to stop using the marker, since I would otherwise need to paint most of the book yellow. Nicolaj`s book falls in this third category. It is extremely concise and practical, and I would highly recommend it to anyone looking to raise capital for a start-up company.
