- "The idea is the core of a company and what defines it entirely"
But ideas change. An early stage company might work on a completely different idea next week, or a company that has not found product/market fit might pivot. Will the company have changed? It will still have the same founding team, still have the same employees, and the same tech. I don't think there is any evidence (none was provided) for how an idea "defines a company entirely".
- "That’s where an investor’s evaluation will start and end"
Bullshit. I know you are (were?) an investor, but it would be wrong to say that your method of evaluation is the way all people evaluate. Could a team of idiots with a great idea get funding? To give a pathelogic case, could a team with an amazing idea to change social networking, made up of unproven non-coders in a distributed team spread across the Eastern Europe, get funding? No.
- "Idea = “market + problem + opportunity”"
Well, if you redefine the term, its quite easy to say it has value. But even this disregards the value of the team.
- "If an investor turns you down, they probably think that, in order of probability: your idea is bad"
Again, different investors are different. There are plenty who look at the team first.
- "BUT, extraordinary teams executing extremely well on any idea doesn’t guarantee success."
Any team worth anything will pivot away from a bad idea.
But the biggest criticism I think I have is that the reason "ideas are worthless", is because you can't think up a good market, opportunity, and customer base. You start with the kernel of an idea, and refine it through continuous customer development, until you have a product which may differ substantially from the initial idea.
