our call

Start with Fomo — highest vibe code, weakest moat.

Fomo

you can rebuild

  • Recent order notification toast rendering
  • Shopify order webhook receiver and event queuing
  • Geo-location display based on order IP or city
  • Customizable popup styling, position, and timing controls
  • Impression logging and click-through analytics

what you lose

  • Pre-built integrations with third-party platforms like Mailchimp or Trustpilot
  • Out-of-the-box visual CSS customization UI
  • Native A/B testing engine for popup variations
  • Complex device-level and URL-matching targeting rules
  • Managed global CDN handling high impression throughput

real moats

  • Turnkey pre-built integrations library across 100+ SaaS platforms
  • Zero-code installation for non-technical store owners
  • Managed edge infrastructure optimized for millions of low-latency requests

Sovendus

Writing the post-checkout widget and backend logic takes under two weeks with AI. However, Sovendus is an ad network relying on critical mass; building the software leaves you with an empty platform and zero customer acquisition power for your merchants.

you can rebuild

  • Iframe and script tag rendering on checkout confirmation pages.
  • Dynamic coupon code generation and allocation pipelines.
  • Merchant reporting dashboard for impression, click, and conversion analytics.
  • Basic customer segmentation by cart value, location, and language.

what you lose

  • Access to millions of active, high-intent European shoppers on post-checkout pages.
  • Turnkey monetization of your own post-checkout confirmation page traffic.
  • Automated clearinghouse settlement between cross-promotional retail partners.
  • Pre-negotiated offer inventory from top European enterprise and mid-market brands.

real moats

  • A locked network of 5,000+ European e-commerce publishers generating massive cross-network traffic volume.
  • Contractual exclusivity agreements with large mid-market brands preventing multi-homing on alternative checkout networks.
  • Decades of historical conversion data optimizing offer matching algorithms across European consumer demographics.
