If you're a second time founder, or have been a VC in the past, one thing against you in fundraising is that, although you're more knowledgable, you're more jaded and reticent to believe your own hype & leaps of faith.
No. I simply leveled up my ideas to match my scrutiny. The only thing I'm jaded about as a 2nd/3rd time founder is VCs so I save tons of time. Also jaded on need for co-founders for most startups. I just build and sell customers things they love. Going great!
