The hub model: one page pointing at a body of work that lives elsewhere.
What they show
A deliberately small homepage that works as a directory rather than a portfolio: her current role as co-founder of Sundial, her book, her essays and newsletter, talks, and social channels. No case studies, no product screens. The substance is the writing, which covers how to adapt your leadership style as a team grows, career strategy, and how product development is changing, and it sits on other platforms that the site simply points to.
Why it works at this level
When your leadership thinking is already a book and years of essays, a portfolio site's only job is to route people to it without getting in the way, and that's exactly what this does. It's a useful counterexample to the instinct to put everything on one domain. The site also demonstrates the founder transition cleanly: a decade running design at Facebook is a single line, the company she's building now is the first thing named, and the writing is what carries continuity between the two. For a leader thinking about starting something, it shows that the audience you built as an executive is the asset you take with you.
What to steal
If your best thinking already lives in a newsletter, a book or a talk archive, make the homepage a clean index of it rather than reproducing it. Lead with what you're building now, not what you led before. Keep the past role to one line; the writing proves it.
What I'd change
One thing I'd push on. Every site here is good; this is the note I'd send the author.
There's almost nothing about Sundial itself on the page, so a visitor learns she's a founder without learning what the company does. One sentence would fix it.
