How to present your code to potential buyers?

An investor only cares about money. Investors start at the exit and work backwards. Knowing this, pitch your project in terms of the return they will get in their investment.

Key points would include:

• Your expertise: Do you know the market you want to sell in to? Are you leveraging your expertise in some way to make the project a reality?
• Risk: Using your already existing code base lowers risk in terms of both time and money. They will probably do technical due diligence to validate your claims, so be honest here.
• Time to Market: Having a code base in place will reduce their time to market, which may be significant.
• Vision: They need to know that there is a future for your product. This is your chance to get them excited!

Investment is about the future, not the past, so understand that you need to achieve what you are promising. The path you trod to get to where you are now may be interesting, but largely irrelevant to the investor. What I'm trying to say is sell the vision, not where you are now or where you've been.

Good luck and hope you get what you need!

If they're non-technical, it won't matter. It will be like trying to sell a high-end bike to people who don't know a bike from a car. 15k lines of code won't matter to them any more than 300k lines of code will.

You need to find something other than the actual code to wow them with.

Can you code up some demos and tell them how short time it will take them to build similar applications with your code? Like "If you use my code, you can build this multimedia application in 15 minutes without writing more than a few lines of code". Non-technical people generally love saving time and money.

It probably depends on how "slightly" they are in the non-technical department.
