Competitor weakness map

  • iFax ($17.99-27.99/mo): 2.9 stars on SiteJabber. Free trial scams. No AI — just sends images. No document understanding, no routing, no auto-fill. 1990s technology with 2020s pricing.
  • CamScanner ($7M/mo): Malware scandal. Privacy nightmare — Chinese-owned, sends data to servers. Dark pattern subscriptions. No document understanding — just OCR and PDF conversion.
  • Artisan (Ava): Horizontal — no industry-specific playbooks or compliance awareness
  • Dashboardly ($39/mo): Profit analytics only — no fulfillment monitoring, no payout reconciliation alerts, no content-to-revenue attribution
