When Cal.com wins
- Privacy-conscious teams that want self-hostable scheduling
- Teams already in the open-source ecosystem who ship their own infra
- Buyers who want SOC 2 and HIPAA compliance without Calendly's $15,000 Enterprise floor
Where Cal.com is the wrong fit
- Solo professionals where Calendly's Free tier is already sufficient

- Buyers who do not care about open-source or self-hosting
When Postscript wins
- Shopify e-commerce stores doing $1M+ GMV with active SMS list growth
- Brands graduating from Klaviyo SMS or Attentive on cost
- Teams wanting a Shopify-native SMS experience separate from email
Where Postscript is the wrong fit
- B2B companies, where SMS is not a standard channel
- Creators or info-product sellers whose per-message economics do not match
- Brands without an SMS-friendly Shopify segment to drive ROI
