It's interesting how at least several of the failures were good ideas with bad timing/execution that others have replicated successfully.

iCab: Uber obviously was very successful with this ~same premise

Smart Charter: I assume you can easily book a private jet online now?

Founder's Forge: linking record-keeping and payment is what makes Ramp great; 10 years of fintech innovations made executing this much easier

Spark Innovations: this is basically the premise of Airtable

As they say: ideas are easy, execution is everything.

ideas are cheap. everyone has them. building a succesful business out of ideas is hard. really hard.

It’s honestly both. A good idea that’s actually feasible and has some kind of moat is extremely hard to come by.

Most things that are new but not working can be solved by "I should try this again later" after the landscape has changed a little, whether that's supporting technologies, how receptive your market is, if your market even exists yet.
