What's new.

Waitlist open.

First public version of stax.report is live. The marketing site, the demo dashboard, and the waitlist form all work. The product itself is still in build.

If you join in the first 100 sign-ups, you lock in founding-member pricing of $29/mo flat — forever. Access opens in batches over the next four to six weeks.

• Live demo: the dashboard surface is clickable at /dashboard with sample data.
• Waitlist form: email, monthly spend range, and an optional pain-point field that shapes the build order.
• Footer pages: privacy, terms, security, and changelog all shipped.

Design system locked.

Tokens, type, component patterns all settled before product code starts. Paper-and-ink palette with a single brand accent — money green at #1F9D5C. Geist + Geist Mono with tabular numerals baked in.

• One accent color. Every other hue is informational, never decorative.
• Tabular numerals everywhere. Money columns line up to the pixel.
• Restrained radii. 7px buttons, 10px cards, 14px containers — no pillowy wellness vibes.

Provider matrix v1 finalized.

Mapped 8 providers across two axes: how billing data is reachable (API key, OAuth, invoice scrape) and how seats are reachable. The matrix decides build order — high-reach + high-volume first.

• API-key providers shipped first: OpenAI, Anthropic, Mistral, Google AI.
• OAuth providers next: Cursor, Copilot, ChatGPT Team, Perplexity.
• Card-feed fallback for anything else: Stripe Issuing, Brex, Ramp.

Reddit deep-dive concluded.

Four weeks reading every thread I could find about founders complaining about AI cost. ~300 posts across 7 subreddits. The three complaints that kept repeating became the brief — invisible subscriptions, unreadable UIs, variable cost-tracking pricing.

Output: a one-page brief that the entire product still maps to. Founding post →
