Matthew, I think you may have misinterpreted my response. The question being asked is whether seed stage investors invest at the idea phase or do they need to see more.
I answered that it depends. Every investor is different, every idea is different, and every entrepreneur pitching an idea to investors is different. So...it depends.
I shared a few examples where investors
may invest at the idea stage. May being the operative word.
I never suggested that investors should ignore looking at ideas or listening to pitches that are still in the idea phase. Nor did I ever say that I would
"refuse to even look at the idea" as you suggested in your response.
What I said was that seed investors aren't likely to invest at the idea phase. Investors are business people too. They only have so much time and a finite amount of capital to invest at any given time.
Your mention of Newton, Tesla, and Salk only support my response. Each of those men put their ideas into action. Anyone could've had the same idea but it was their execution that made all the difference.
Investors get pitched ideas every day. It's very common to be pitched the same idea by several different entrepreneurs. All things being equal, the investor will choose to invest in the business that has begun to execute on the idea and can demonstrate that they have what it takes to succeed.
