Of course. My IP attorney (Tennille Christensen) reviewed the whole situation and signed off on it. I have her written opinion in my inbox. There were particular IP issues around the name and the domain, but I avoided those by changing the branding from what I was thinking originally.
None of the core technology is related to my work at Intuit. I wouldn't steal that even if I was unethical and reckless... a lot of it predates the internet. But I know there's a business there and I know that there is lots of room to innovate.
I'm not a lawyer, but as far as I know the non-compete it's unenforceable in California, where I live. It would be unwise to recruit from Intuit in the first year though. That would be inviting a suit.
