our call

Start with Sovendus — highest vibe code, weakest moat.

RTB House

RTB House is not a software app; it is a full-stack demand-side platform (DSP) and ad exchange buyer executing real-time bidding in milliseconds. AI can build a catalog sync and bid configuration UI, but it cannot grant you ad exchange seats, sub-20ms bidding infrastructure, or billions in ad credit lines.

you can rebuild

  • Client-side tracking pixel script and event ingestion pipeline.
  • E-commerce product catalog feed parsing and inventory syncing.
  • Rule-based audience segmentation (e.g., cart abandoners past 7 days).
  • Dynamic ad banner template generation and HTML product rendering.
  • Basic campaign management dashboard and performance reporting UI.

what you lose

  • Access to global SSP ad inventory (Google Open Bidding, PubMatic, Magnite, Index Exchange).
  • Sub-20ms real-time bidding infrastructure distributed across global data centers.
  • Proprietary deep learning algorithms optimized specifically for dynamic display retargeting.
  • Fully managed service including custom creative design and campaign optimization.
  • Enterprise-grade ad fraud protection, brand safety, and viewability filtering engines.

real moats

  • Proprietary deep learning bid valuation models trained on multi-billion dollar conversion data.
  • Direct DSP exchange seats, massive buying scale, and established credit lines across global SSPs.
  • End-to-end managed service with dedicated yield ops teams and custom dynamic ad creative generation.
  • Direct integrations with Privacy Sandbox Protected Audience API (PAAPI) testbeds at enterprise scale.

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.
