What Energy Data does

Energy-Data.io, a brand of Onyx Dynamics Ltd (incorporated in Mauritius, founded 2020), builds an agentic AI workspace called Ed for weather-normalized energy data analysis and IPMVP-compliant M&V reporting. The platform combines a proprietary Degree Day Database — fusing ISD, MADIS, DWD, and GHCN-Daily station records with ERA5 and MERRA-2 reanalysis — with deterministic regression services that produce auditable savings reports, statistical quality metrics (CV(RMSE), NMBE, R²), and methodology documentation aligned to ISO 50001, ISO 50015, and ASHRAE Guideline 14. Natural-language requests are interpreted by Ed and dispatched to these compiled calculation services; the architecture intentionally separates AI orchestration from numerical computation so every output is traceable to source data.

The product surface spans four distribution shapes: (1) Ed itself as a tiered SaaS workspace with a 7-day trial, Pro ($59/mo) and MAX ($159/mo) plans; (2) a REST API for embedded use inside EnMS platforms, priced at Essential/Advanced/Enterprise tiers ($47/$187/$297 monthly); (3) MCP connectors that surface degree-day lookups directly inside Anthropic Claude and (announced) OpenAI ChatGPT, including a free tier with no separate API key; and (4) a done-for-you Energy Consulting service line for AI workflow setup, ISO 50001 advisory, and on-demand M&V. Universal data ingestion handles CSV, XLSX, and PDF utility bills, performing automated column mapping, unit normalization, and timezone alignment. Hosted on Supabase over AWS in the EU region with isolated workspaces per customer.

Customers are energy managers, ESCOs, energy consultants, and corporate sustainability teams needing CFO-defensible savings verification; named logos include Toyota, FedEx, Rossmann, Millennium Hotels, Engie, GE, Shell, Kaercher, Bosch, Danfoss, DHL, PepsiCo, Harvard, and Decathlon. The go-to-market is product-led self-serve plus founder-led enterprise and consulting engagement, with content marketing (degree-day education, ISO standards documentation), community partnerships (EU Tech Chamber Energy Alliance, Climate Score Organization), and AI-assistant marketplaces as the top-of-funnel. The firm is bootstrapped — no funding rounds disclosed — and operates with a 1-10 core team supplemented by freelancers and advisor Karl-Heinz Schulte.

Emerging players

• Arcadia: Clean energy data platform serving utilities, developers, and corporate sustainability teams with interval data and ESG reporting. Adjacent rather than directly overlapping, but pursues a similar AI-enabled data infrastructure thesis.
• GridPoint: Building energy management and submetering analytics platform with live monitoring and savings tracking. Targets similar enterprise energy teams but adds hardware/sensor layer that Energy Data does not provide.
• 75F: Cloud-based smart building platform combining IoT hardware with analytics for HVAC and energy optimization. Comparable buyer (facilities and energy teams) but different delivery model (hardware-led vs software-only).
• BuildingIQ: Building energy analytics platform focused on HVAC optimization and continuous commissioning for commercial real estate. Overlaps with Ed's weather-normalized savings verification and portfolio management use cases.

Direct peers

• UtilityAPI: Automated utility data acquisition and customer enrollment platform serving clean energy and energy management programs. Comparable to Ed's universal data ingestion and API-first distribution model.
• EnergyCAP: Utility bill and energy data management platform for enterprise and higher-education customers. Overlaps with Ed's multi-site metering, bill ingestion, and portfolio dashboarding workflows.
• Degree Days.net: Long-standing specialist providing heating/cooling degree day calculations for building energy analysis. Most direct competitor to Energy Data's Degree Day Database and API offering, serving the same energy manager and ESCO buyer.

Broad incumbents

• Schneider Electric EcoStruxure: Global incumbent offering building automation, energy management, and sustainability suites. Competes at the enterprise level with bundled offerings that include M&V-adjacent analytics across a much broader portfolio.
• Siemens (Building X / EnergyIP): Global industrial incumbent offering building operations, energy data management, and grid analytics. Represents the bundled incumbent threat to Energy Data's standalone energy data analytics positioning.
• Honeywell Forge: Sustainability and building management platform from a major industrial incumbent. Provides overlapping energy analytics, benchmarking, and M&V-style reporting as part of an integrated facility operations stack.
