our call

Start with Gorilla ROI — highest vibe code, weakest moat.

Gorilla ROI

Gorilla ROI is a wrapper that fetches data from Amazon's SP-API and formats it into Google Sheets custom functions. Building the technical integration takes days using Cursor or Claude. The only friction is navigating Amazon's strict SP-API security approval process.

you can rebuild

  • Custom Google Sheets functions for querying SKU-level sales, quantities, and revenue
  • Automated periodic sync of FBA inventory levels and replenishment projections
  • Amazon advertising report ingestion including TACoS, ACoS, and campaign spend
  • Itemized fee breakdowns including storage, fulfillment, and refund charges
  • Multi-region marketplace currency conversion and data aggregation

what you lose

  • Pre-approved Amazon SP-API app credentials (bypassing developer review)
  • Pre-made financial and inventory Google Sheets template library
  • Managed retry logic and automatic queueing for Amazon's burst rate limits
  • Zero-maintenance schema updates when Amazon changes SP-API endpoints
  • Shared infrastructure for handling multi-account API keys securely

real moats

  • Approved Amazon SP-API Developer Application status
  • Pre-built library of financial modeling templates natively linked to custom formulas
  • High switching friction for users who have built custom formula-heavy workbooks

Polar Analytics

Polar Analytics is a bundled warehouse-native BI stack with standard SQL pipelines and an MCP interface. You can replace the entire UI and reporting layer in days using LLMs, DuckDB/Postgres, and dbt; you pay Polar purely to avoid maintaining API integrations and data models yourself.

you can rebuild

  • Centralized executive e-commerce dashboards (MER, Blended CAC, LTV, ROAS).
  • Cross-channel ad spend aggregation (Shopify + Meta + Google + TikTok + Klaviyo).
  • Pre-built SQL transformations and semantic metric definitions.
  • LLM query layer / MCP endpoint for querying data via natural language.
  • Basic cohort analysis and customer retention heatmaps.

what you lose

  • Dedicated data engineer and customer success manager support included in enterprise plans.
  • Out-of-the-box maintenance of broken ad platform API endpoints and webhook ingestion failures.
  • Managed server-side conversion API proxying (Meta/Google CAPI).
  • Turnkey execution of statistically sound incrementality tests without hiring data scientists.
  • Zero-maintenance Snowflake instance hosting and optimization.

real moats

  • Pre-aggregated cross-platform data connectors kept current against constantly changing third-party ad APIs.
  • Standardized e-commerce metric definitions (semantic layer) tuned for thousands of edge cases in Shopify refund/tax/shipping reporting.
  • Turnkey multi-touch attribution and causal lift incrementality frameworks managed by dedicated data teams.
