Most importantly, we have a really good team: Alexei Andreev, Eric Rogstad, Stephanie Zolayvar, Eric Bruylant, and support from some excellent advisers: Eliezer Yudkowsky3 and Anna Salamon4\. We have raised a modest pre\-seed round in 2016, all from individual rationalist / EA angel investors, which should last us for a bit while we grow the platform to secure future funding\. 5
In both the notes, "recent pivot", I'd avoid pivot framing, to go with the whole "we're building the next part" thing.
Also, the framing of "the final decisions are made by the core team" sounds vaguely power / conflict-y, I'd suggest something more gentle.
And mention Nate as a previous adviser?
