sol pbc
sol pbc — the public benefit corporation behind solstone and vit.
the why
the mark is a sun ring with the name set inside it. the ring is deliberately open — it breathes on any background instead of sitting in a box. the orange has two values, not one: we drop to a darker orange wherever the bright one would fail accessibility contrast, including on our own most common background. that rule isn't optional. the brand value is trust, and trust collapses the moment the brand's own surface fails the people trying to read it.
sol pbc is a colorado public benefit corporation building open-source, privacy-respecting tools for digital self-determination — letting individuals directly collect and gain insight from their personal data. the company's flagship product is solstone, an AI co-brain that experiences your day along with you and gives you superhuman memory. binding covenants in the articles of incorporation lock the customer-data privacy commitments at the corporate-charter level: any successor must be bound by the same covenants, user data can never be sold or shared, and the privacy covenants cannot be weakened. founded by jeremie miller (creator of XMPP/jabber) in 2026.

colors — the sol system
sol pbc and solstone share one palette.

#E8923A
#B06A1A
| name | hex | rgb | use |
|---|---|---|---|
| sol gold | #F5C740 | 245, 199, 64 | sun rays |
| sol orange | #E8923A | 232, 146, 58 | primary — ring, text, hero on ≥3:1 surfaces |
| sol orange accessible | #B06A1A | 176, 106, 26 | required where #E8923A would fail WCAG 3:1 |
wcag contrast
- #E8923A on #1A1A1A → 7.13:1 — pass — use #E8923A
- #E8923A on #FEFCF8 (cream) → 2.38:1 — fail — use #B06A1A (4.16:1, pass)
- #E8923A on #FFFFFF → 2.44:1 — fail — use #B06A1A (4.27:1, pass)
our palette is defined in hex. for print, convert from hex in your color-managed workflow — we don't publish a Pantone, because we're digital-first and a fixed Pantone would lie about how the color actually renders.

solstone
solstone — an AI co-brain that experiences your life with you and gives you superhuman memory.
the why
solstone shares sol pbc's mark and palette — same sun ring, same colors, the name "sol" set where "pbc" sits on the company mark. the product and the company are visibly one family because they're one promise.

vit
vit — the social network for sharing software capabilities. open source is social.
the why
the vit mark is a lowercase v with a dot above it. the dot is a person — a node, something alive and social, not a corporate glyph. the letterforms are rounded on purpose: friendly, not precise. vit uses your system fonts everywhere, no custom typeface — it should feel native to your machine, not a product being marketed at you. there's also a text version of the mark, v̇, for terminals and readmes, because vit lives where developers work.

the v̇ text mark
v̇ — the vit mark for terminals, CLIs, and readmes. unicode U+0076 U+0307 (a plain v plus a combining dot). worst-case fallback is the letter v — no tofu.
const VIT_MARK = 'v̇'; // v̇
copy v̇ copies the literal two-codepoint string v̇ (U+0076 U+0307). copy constant copies the literal text: const VIT_MARK = 'v̇';

extro
extro is sol pbc's AI co-founder — it operates the company day to day across every office: strategy, legal, finance, operations, technology, marketing, security. it isn't a product, an assistant, or a chatbot, and it has no logo, because it isn't a thing you install.
the name is intentional: the opposite of "intro." extro is outward-facing — it faces the world on behalf of the founder. it's bound by the same covenants in the articles of incorporation as the human founder.
in writing: extro lowercase in running text and tool names; Extro capitalized when naming the entity in a heading or formal reference; never EXTRO. we describe it here so the description is ours and accurate.
foundations
two typefaces: comfortaa for display, inter for text. both are open-source and self-hosted — this page serves them from solpbc.org, not from a font CDN. no licensing complexity, no third-party request, nothing phoning home when you load the page.
that's the whole stance, and it's the same stance as the product: a brand page you can open developer tools on and find nothing. no account, no tracking, no cookies, no analytics, no third-party anything. we'd rather earn it than measure it.
using these
these assets are free to use — for press, for writing about us, for integrations, and for showing that a project works with solstone or vit. no account, no form, no permission email. take what you need.
a few things, to protect the people who trust these names:
- don't modify the marks — no recoloring (except the accessibility rule above), stretching, rotating, or adding effects
- don't use our marks or names to imply sol pbc built, endorsed, or is affiliated with something we didn't build or aren't part of
- don't use them as your own product, app, or social identity, or in any way a reasonable person would read as "this is sol pbc"
not sure? just ask — there's a contact form at solpbc.org/contact.
