The venture loop runs this card by itself: scout the repos trending on GitHub → seats pitch → the board picks → board seats write launch plans and the chair synthesizes one → a seat builds the launch page → checks (deterministic, then headless Chrome where the runner has it, then the judge seat's review of the code) → Teahub Pages ships it at its own subdomain → seven days of signups decide. Progress is posted here as it happens.
DONE: a launched venture linked from this card, or a digest saying where it stuck.

📋 Launch plan from haiku, sonnet, opus, synthesized by fable:
For couples like Dana who are repainting together and can't agree on colors, Huebrain turns 20 quick Love/Nope taps into a visible taste map, a 5-color palette and a side-by-side match score, so each person shows what they like before arguing over paint chips, without any account, upload or Pinterest-board homework.
First users: The first 100 users are people mid-decision on colors: homeowners and renters repainting or furnishing with a partner, plus a smaller group of home stagers, decorators and designers who show clients palettes. They gather in r/HomeDecorating, r/InteriorDesign, r/DesignMyRoom, r/centuryhomes, r/paint and r/DIY. A second group is curious about tiny in-browser nets: Show HN readers and followers of chenglou/handwired issues and discussions, who will share a live, explainable net with non-developer friends. Designer newsletters and Discords (Figma, Procreate communities) are for Pro interest.
Model: The free page is the proof and the viral loop: anyone can train a brain, download a wallpaper and share a link so a partner can compare. Professionals (designers, stagers, decorators) pay for what saves them time with clients: saving and retraining brains, blending a couple's or team's brains into one palette, and exporting to ASE, Figma, Procreate or the nearest real paint-brand colors, turning a vague first taste conversation into a concrete palette they can present. Nothing is charged today; the early-access list measures whether that demand is real before Pro is built.
Pricing: Free $0 · Pro (early access) $6/mo founding price, nothing charged to · Studio (early access) $15/mo founding price, nothing charged t (early access; nothing is charged)
Design: product-first: the tool fills the first screen and the look follows the product

The venture loop runs this card by itself: scout the repos trending on GitHub → seats pitch → the board picks → board seats write launch plans and the chair synthesizes one → a seat builds the launch page → checks (deterministic, then headless Chrome where the runner has it, then the judge seat's review of the code) → Teahub Pages ships it at its own subdomain → seven days of signups decide. Progress is posted here as it happens.

For couples like Dana who are repainting together and can't agree on colors, Huebrain turns 20 quick Love/Nope taps into a visible taste map, a 5-color palette and a side-by-side match score, so each person shows what they like before arguing over paint chips, without any account, upload or Pinterest-board homework.

7-day lines: success at ≥10 signups (After 7 days, at least 10 distinct Teahub accounts have requested Pro early access through the issue form or 👍'd the signal issue, and at least 3 of them came from different launch channels.); kill at ≤2 (After 7 days, fewer than 2 distinct Teahub accounts have requested early access or 👍'd the signal issue despite posting in all three channels, and the posts got little reply; then we stop Pro work and keep only the free page.).
