Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
saas-corpus
A citation-backed knowledge base of how real B2B SaaS companies were actually built. Adds 153 entries to Claude Code: 25 company case studies (Figma, Stripe, Linear, Notion, Snowflake, Datadog, Cursor, Harvey, Atlassian, Ramp, and 15 more), 100+ atomic notes with verbatim founder quotes and dated metrics, 8 function guides (PLG, sales-led, pricing, fundraising, hiring, founder leadership), 4 stage playbooks (pre-seed through scale), 7 failure post-mortems (Quibi, Fast, WeWork, Theranos, Jawbone, Clubhouse, Homejoy), 4 framework syntheses (Obviously Awesome, Play Bigger, MEDDPICC, Crossing the Chasm), and benchmark tables. When you ask Claude about SaaS strategy, fundraising, pricing, GTM, or founder decisions — instead of generic LLM advice, you get specific cases with verbatim quotes, dated numbers, and explicit "when this pattern applies / when it does NOT apply" guardrails to prevent cargo-culting. Every claim cites primary sources (S-1 filings, founder interviews, annual letters). Updated regularly. MIT l
