About

How this is made, and why you can check it.

This teaches securities mechanics, tax deadlines and equity math to people who will act on them. That deserves a page explaining where the content comes from and what it refuses to do.

The arithmetic is code

Cap tables, SAFE conversions, option pool shuffles, exit waterfalls, runway and SaaS metrics are computed by pure functions with unit tests and documented formulas, not written out as prose and hoped over. Where more than one accepted method exists, the product names the one it uses and says why.

No language model performs arithmetic anywhere in this product. Every number you see in a lesson is asserted in a test against the calculator that produces it, so the worked example in the text and the tool you use afterwards cannot disagree.

Legal and tax content cites primary sources

Formation, tax and compliance lessons cite the original documents: IRS publications and forms, the Small Business Administration, the Delaware Division of Corporations, the Federal Trade Commission, the Copyright Office and SEC investor alerts. Fundraising content is grounded in public model documents rather than hearsay.

Where something is common practice rather than law, it is labeled as common practice. Where it varies by state, it is flagged as jurisdiction dependent. Where it is one person's opinion, it says so. The product does not borrow authority it does not have.

What it will not do

  • It will not tell you what to do. It is education, not legal, tax, accounting or investment advice, and it says so on every page.
  • It will not assume you should raise venture capital. Bootstrapping is treated as a real strategy, not a consolation prize.
  • It will not cover jurisdictions it does not know. The legal and tax material is United States only and scoped to Delaware C corporations and home-state LLCs.
  • It will not track you, email you without being asked, or sell anything to anyone about you.

Built to a standard you can inspect

36 lessons and 105 glossary terms sit behind a test suite that checks the content as strictly as the code: that every worked figure matches the calculator, that every cross reference resolves, that no lesson runs longer than the time it claims.

The interface targets WCAG 2.2 AA. Every route is scanned by axe in continuous integration and color contrast is measured by hand in both themes. The site you are reading now ships no third-party JavaScript, no cookies and no analytics beacon, and the app works with the network switched off.
