A track pack is practice beside the free concept cards: one worked example, one checklist, and one change in a prompt or a repo you already have. The Foundations token budget set is written. The other sets and the other packs are not.
There is no form on this page and nothing is stored. A waitlist link opens an email to support@buildsparkai.com with the tier and the track already in the subject. The Foundations token budget set is readable now. It is not a payment page.
Foundations, first
The first sets for the Foundations pack sit next to the live Foundations cards. The token budget set is written.
- Token budget A worked per-request and monthly cost example, with the input, output, and cached-input split, plus a pre-launch cost checklist.
- Context layout Decide what stays in the window for one real request, and what to drop.
- Prompt rewrite Turn a loose instruction into one a teammate could reuse.
One pack per track
- Foundations €39 once, not a checkout. The token budget set is on the pack page. Context layout and prompt rewrite are not written yet.
- Retrieval & Grounding €39 once. Practice for finding source text and keeping an answer tied to it.
- Agents €39 once. Practice for tools, loops, and what still waits for a person.
- Ship & Maintain €39 once. Practice for evaluation, cost, latency, and privacy after launch.
The email button is only the Foundations pack. Each pack page has its own waitlist link, with that track in the subject. Founding members ask for about 30% off from the same address. No payment is taken here.
