Ask HN: Key Man Insurance for Startups?

Hey, I've been plotting to throw off the cruel yoke of salaried employment for a while now. Just a couple months before I was going to put in my notice and sneak off, though, I had a mild heart attack.

I can't leave my wife, kid, and business partner high and dry if something happens to me, but getting key man insurance seems like it's going to be vastly more difficult now.

Do any of you have recommendations for how to shop for it? I'm sure I'm not the first business owner to spend too many Sundays praying beneath the Golden Arches and pay the price for it.

(Sorry to submit this as its own post, but I've been digging pretty hard and not coming up with much..)
