As answered by people managing Eloquent JavaScript and The Red Arc Data Deck.
The Red Arc Data Deck's answer:
TRA Data Deck is an India-first ESG and financial data platform, built ground-up for SEBI's BRSR framework and local disclosure standards, a space where global vendors barely scratch the surface. We track 1,000+ KPIs spanning carbon (Scope 1/2/3), NOx/SOx, water, waste, social, and governance metrics, every data point traceable back to the original filing.
What really sets us apart: 48-hour refresh cycles — not weeks, not quarters Customisable ESG data — no black boxes, no one-size-fits-all Dashboards and API in a single product — at a fraction of what incumbents charge
The Red Arc Data Deck's answer:
We cover India's top 1,000+ listed companies with BRSR-native granularity and full source traceability.
Lower total cost of ownership. Comparable (and locally richer) coverage at a meaningful discount to incumbents and we don't penalise you with per-seat pricing.
Workflow-ready from day one. Custom data points, ready-to-use dashboards, and a clean API mean you're integrated in weeks, not months.
Built for mid-market firms that need credible ESG and financial intelligence — without paying tier-1 vendor prices.
The Red Arc Data Deck's answer:
When SEBI mandated BRSR disclosures for India's top 1,000 listed companies, a wave of structured sustainability data suddenly hit the public domain. Global ESG vendors treated India as a tail market, and local solutions were fragmented and largely manual.
The Red Arc built Data Deck to fix that — a cloud-native platform purpose-built for Indian disclosure standards, priced for mid-market firms, and delivered through dashboards and APIs that fit how analysts actually work. Our mission is simple: bridge the gap between data complexity and business clarity.
The Red Arc Data Deck's answer:
TRA Data Deck runs on a modern, AI-native cloud architecture — leveraging GCP, FastAPI, and enterprise-grade AI to deliver ESG and financial intelligence at scale.
What that means for our customers:
The Red Arc Data Deck's answer:
We're currently building partnerships and running pilot engagements with organisations across the ESG, financial services, and corporate sustainability ecosystem.
The Red Arc Data Deck's answer:
Anyone making decisions that depend on credible ESG and financial data on Indian companies:

Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
