ESG data platforms: the underwriting layer for the climate transition
Insurers, lenders, and asset managers need ESG data to underwrite. The platform that aggregates climate, social, and governance signals into a single API is the underwriting wedge.
Why now
Climate risk became a real underwriting variable in 2024-2026. Sustainalytics and MSCI ESG are expensive and slow. The API-first, real-time, lower-priced alternative is open.
The idea you could build today
Aggregate public data: SEC filings, EPA emissions, OSHA incidents, news mentions. Normalize into a single per-company score. Ship as an API. Per-query pricing.
Build stack
- ·Public-source ingestion (SEC EDGAR, EPA, OSHA)
- ·Postgres + Elasticsearch for the search graph
- ·Anthropic Claude for the entity resolution
- ·REST API for the per-company queries

The seed-round pattern hiding in the trendline
ESG OSS with velocity in the "source aggregation" or "per-company score" modules are the seed-stage tells.
Frequently asked
What about Sustainalytics / MSCI?+
Both are enterprise SaaS with multi-week onboarding. The API-first, per-query version wins the long tail.
