Founder's: which is more innovative, an idea or execution?

You need both anyway... almost everyone has some ideas but not everyone can execute them and deliver results. An idea without execution is only a dream. :)

I think both!

I think execution. Innovation only begins when you seek feedback and iterate based on that feedback. The idea will always adapt and change over time throughout the startup process, but the one constant is your ability to pivot and change course when the feedback is directing you to do so.

I am on the execution side. Ideas without a plan to execute remind me of this "idea guy" https://hard-drive.net/hd/video-... “Listen, I’m the ideas guy,” reads a post Lee made on Steam’s community forums. “I’ll handle the social media and work on the story, but I need people to do the less important stuff like graphics, coding, sound design, AI and the rest of that boring bullshit.”

Execution is the true test of innovation, as it transforms an idea from concept to reality. A brilliant idea might be a dime a dozen, but innovative execution is what truly sets a founder apart.

Execution breathes life into ideas, making it the true measure of innovation. Shiv Bhushan Singh, it’s the meticulous and creative realization of an idea that truly sets a founder apart.

Both, but execution is way cool

I'll agree with others about the execution. The idea can be great, but many people can have ideas and they won't get you far without being turned into something others can actually see and use.

Execution every time, everyone has ideas

You can't have one without the other.
