Example session with this skill installed

- Read your context and instructions
- Compiled the company research
Summary
Analysed 3 websites live on 2026-10-08 (about 10 s each, well under one cent in total). linear.app and notion.so share a modern Next.js + React stack on Cloudflare with a headless CMS; basecamp.com is deliberately lean.
Stack by site
| linear.app | notion.so | basecamp.com | |
|---|---|---|---|
| Technologies found | 16 | 15 | 6 |
| CMS | Sanity | Contentful | – |
| Framework | Next.js, React, styled-components | Next.js, React | Stimulus (Hotwire) |
| CDN | Cloudflare, Google Cloud CDN | Cloudflare | Cloudflare |
| Hosting | Google Cloud | Vercel | – |
| Analytics / ads | LinkedIn Insight Tag | LinkedIn Insight Tag, LinkedIn Ads, Naver Analytics | – |
| Marketing automation | – | – | Mailchimp |
Takeaways
- Headless CMS is the norm for product-led SaaS marketing sites: Sanity (Linear) and Contentful (Notion).
- LinkedIn is the paid channel both Linear and Notion instrument, a hint at B2B account-based campaigns.
Basecamp runs its own Rails/Hotwire stack with almost no third-party marketing tags, consistent with its privacy positioning.
Next steps
- Ask for full version numbers and confidence scores per technology.
- Take a mobile screenshot of each pricing page to compare positioning.
- Run the same check on a list of 50 prospects and filter for one technology.

Ask things like
- "What is linear.app built with?"
- "Which of these 30 prospects run HubSpot or Marketo?"
- "Does this competitor use Contentful or Sanity?"
- "Show me their pricing page on mobile."
