Big tech giants also have ton of interesting work to be done, yes the pace may be slower than what it would be at a startup or if you just go on a sabbatical. On the flip side, big tech can give you the resources you need to succeed. Why don't you find an intersection between your idea or the reason you leave the big tech and the big tech itself? Then work it out with your manager to transition to that. It may take time but how different it would be from working on your idea, pitching it etc? Why not opt for work of your choice in a big tech giant? Win-Win and even to win at startup lottery, eventually you need to reach the win-win stage!
