Dear non-executive team members,

All of my options have vested, and I haven’t been offered any new ones so my earning potential here is no longer all that great. Worse, as we’ve operated and developed better understandings of the problems we face it seems less likely than ever that we’ll achieve the vision we set out to achieve. Finally, the blackout periods are having a real negative effect on my ability to diversify my wealth and avoid the high risk of this company’s success chances. Therefore I’m leaving on a “high note” while we can still plausibly call this endeavor a success, and after I’ve left will convert all my equity in this venture into other forms of wealth while not having to report it
