VCs can only control the team. That is why they push this idea really hard.
Really? Pitch me one.
Two ideas for you off the top of my head:
Do CRM right for SMBs. (Sounds simple, but it's not, because of the S and the M in SMB).
Do time tracking right (timesheet management for contractors etc.). Never saw a single solution that didn't suck to the extreme.
Bonus tip: Here's a thing though: non techies won't have the advantage a technical person (i.e., adventurous software developer) has: The tech can do it with minimal resources and overheads. If you also have a business sense - that's great. Otherwise break existing market by offering a superior service dirt cheap (but not free!). Once you reach a critical mass, grandfather the existing accounts in their original early bird price and nudge the cost for new customers up a bit. Automate as much as you can and you have a side income with potential to be main income.
Part of the difficultly for me has been realizing that the it's not just a rare, good idea that matters—but that it's a rare and good business idea specifically. For instance, I've had a couple projects that gained interest by researchers, which I took as evidence that they might be uncommonly good; but getting the attention of researchers is different from getting the attention of investors for a reason, and it's still questionable whether either has even above average value as a business idea...
I'd argue both matter. It's just as easy to execute really well on a half-baked idea and get nowhere.
Some examples are SEO, entertainment, and mobile games.
"Everything" can mean every industry and their products.
Of course the movie does actually have to be made, and well, to succeed, but the idea for it is valuable in itself, so long as it is actually an original and interesting idea.
A cynic might suggest that VCs spread the "ideas are worthless" meme for their own benefit.
Or perhaps they only ever really encounter the "uber, for doughnuts" type pitches which indeed generally have little value.
Someone could see a $500/pm idea in this thread, being developed by a solo dev, and think: "that's a good idea". They put a team of seasoned devs on it and created their own $500k/pm version.
