Here is a write-up on couple of books that I liked reading and learning internals about start ups and how it all works. I would recommend both of them equally. Both have their own strong points in various topics. For example, 'High Tech Start Up' shines in the area of market analysis and product planning; 'Engineering Your Start-up' shines in the area of accounting and finance with lots of templates and ready-made excel sheets to get started with planning.
Again, just like any good book and education, learn as much as possible and see what makes sense and relevant for your situation.
First one: (Amazon link) High Tech Start Up, Revised and Updated: The Complete Handbook For Creating Successful New High Tech Companies
It has 14 chapters in total - spanning over 270 pages. The most impressive thing I liked in this book is market and product planning. According to the author, if we assume x-axis being a product and y-axis being a market - following quadrants can be made.
Quadrant 1: New Product and New Market - Missionary sales and tech push. This is where, consumers don't know they need the product and there is no existing product. Typically high risk and costly.
Quadrant 2: Existing Product and New Market - Marketing driven and essentially you are selling new use of the existing product.
Quadrant 3: Existing Product and Existing Market - Face lot of competition. Can be used for income substitution.
Quadrant 4: New Product and Existing Market - Tech push, market pull. Delivering value to existing problem.
It is good if you are in Q4 - where you already have the market and with your product you are innovating. If you are in Q1, you would need lots of money raising to do.
I found chapter 5, which deals with the business planning interesting in that, you would come to realize so many details that make up for a good planning.
Second one: (Amazon link) Engineering Your Start-Up: A Guide for the High-Tech Entrepreneur (2nd Edition)
It has total of 21 chapters spanning over 400 pages. Accounting, Finances, and Term Sheets are dealt really well in this book. 'Rule of X Competitors' and Financial Statements really impressed me from this book.
Rule of X Competitors: Take any market, at any point in time, there is a room for only X viable competitors. As from the definition, obviously, the smaller the X, the better. According to the author, if X is more than 7, you might want to reconsider the plan.
On the Financial Statements, it is tough to cover details in a post like this, however following quick 3 statements are something you want to keep track of all the time.
1. Balance Sheet2. Income Statement3. Cash Flow Statement
Final Note: Rules are there to break and laws are there to follow. So you can read and learn about how it is done typically but just adapt the rules according to your situation.
