1) If you want to H1B yourself, you have to demonstrably give up control of your company to a US citizen. What if none of the co-founders are American? What if you're a solo founder?
2) The B1 visa only gives you 6 months to figure out an alternative. It's unclear what the alternative is, and why add that stress during what is a critical time for your startup?
3) If you have $100K you could go for an E2 visa, but it does not lead to a green card. You have to renew every 2 year. Exiting your company? Get ready to exit the country. It also requires you to create a few (single digits) jobs within the first three years, but that seems less onerous
4) My lawyer suggested that an O1 would be unrealistic unless you've been recognized publically somehow.
5) If you have $500k to $1M, you could apply for an EB. I don't, so can't comment too much here.
Fianally, across the board there's an issue of time and money. Dealing with this stuff will be a big headache that will distract from your company.
